With time and practice, Little Hua will be well on his way to mastering the English language.。

As a normal student, learning English well is always a challenge. However, there are several effective ways to improve your English skills. In this essay, I will share my own experience and give some tips on how to learn English well as a normal student.Firstly, it is important to build a solid foundation of English grammar. Grammar is the backbone of any language, and it is essential to have a good understanding of it in order to communicate effectively. Therefore, it is necessary to spend some time studying grammar rules and practicing them in writing and speaking.Secondly, reading is a great way to improve your English skills.

It is important to practice speaking regularly, even if it is just for a few minutes a day. Speaking with confidence and fluency takes time and practice, but it is achievable with consistent effort.Fourthly, using technology can also be helpful in learning English. There are many apps and websites that offer English language courses and exercises. Some popular ones include Duolingo, Memrise, and Quizlet. These tools can help you to learn new vocabulary, practice grammar, and improve your overall language skills.Finally, it is important to stay motivated andconsistent in your English learning journey.

A new study by the British government has discovered the mental health of the country's teenage girls has become worse.the survey,which included 30,000 14yearold students in 2005 a nd 2014,showed 37 percent of girls with psychological stress,up from 34 percent in 2005.British boys' stress level was actually seen to fall over the same time period,from 17 percent to 15 percent.The report's authors pointed out the“advent of the social media age”could be a major contributing factor for increased stress among teenage British girls.“The adolescent years are a time of rapid physical,cognitive(认知的)and emotional development,”Pam Ramsden,a lecturer in psychology at the University of Bradford in the United Kingdom,wrote in a recent blog post.“Teenagers interact with people in order to learn how to become competent(有能力的)adults.In the past, they would engage with parents,teachers and other adults in their community as well as extended family members and friends.Now we can also add social media to that list of social and emotional development.”Throughout adolescence,girls and boys develop characteristics like confidence and selfcontrol.Since teenage brains have not completely developed,teens don't have the cognitive awareness and impulse(冲动)control to keep from posting inappropriate content.Furthermore,this content can easily be spread far and wide with disastrous influences.Social media can also feed into girls' insecurities about their appearance,Ramsden said.These sites are often filled with images of people with body type unattainable to the normal person.However,these images and the messages tied to them gradually become societal standards.1.The statistics in the second paragraph show that ________.A.more and more children in Britain have mental health problemsB.few girls in Britain suffered from psychological stress in 2005C.more boys in Britain are suffering from mental pressure nowD.more British girls feel psychologically stressed than boys do now2.Contrary to traditional ways of interaction,social media ________.A.helps teenagers develop qualities like confidence and selfcontrolB.has many negative effects on girls' characteristic developmentC.makes teens aware of potential danger of the inappropriate contentD.teaches girls to care about their appearance to meet societal standards 3.The underlined word“advent”in Paragraph 3 can be replaced by“________”.A.arrival B.endC.disappearance D.invention【解题导语】一项新研究发现,英国少女的心理健康状况变得更糟;分析表明,社交媒体时代的到来可能是造成英国少女心理压力加大的主要因素。

T Linguistic forms having the same sense may have different references in different situations.14. F In semantics, meaning of language is considered as the intrinsic and inherent relation to the physical world of experience.15. T Contextualism is based on the presumption that one can derive meaning from or reduce meaning to observable contexts.16.

英语专业八级考试TEM-8阅读理解练习册(1)(英语专业2012级)UNIT 1Text AEvery minute of every day, what ecologist生态学家James Carlton calls a global ―conveyor belt‖, redistributes ocean organisms生物.It’s planetwide biological disruption生物的破坏that scientists have barely begun to understand.Dr. Carlton —an oceanographer at Williams College in Williamstown,Mass.—explains that, at any given moment, ―There are several thousand marine species traveling… in the ballast water of ships.‖ These creatures move from coastal waters where they fit into the local web of life to places where some of them could tear that web apart. This is the larger dimension of the infamous无耻的,邪恶的invasion of fish-destroying, pipe-clogging zebra mussels有斑马纹的贻贝.Such voracious贪婪的invaders at least make their presence known. What concerns Carlton and his fellow marine ecologists is the lack of knowledge about the hundreds of alien invaders that quietly enter coastal waters around the world every day. Many of them probably just die out. Some benignly亲切地,仁慈地—or even beneficially — join the local scene. But some will make trouble.In one sense, this is an old story. Organisms have ridden ships for centuries. They have clung to hulls and come along with cargo. What’s new is the scale and speed of the migrations made possible by the massive volume of ship-ballast water压载水— taken in to provide ship stability—continuously moving around the world…Ships load up with ballast water and its inhabitants in coastal waters of one port and dump the ballast in another port that may be thousands of kilometers away. A single load can run to hundreds of gallons. Some larger ships take on as much as 40 million gallons. The creatures that come along tend to be in their larva free-floating stage. When discharged排出in alien waters they can mature into crabs, jellyfish水母, slugs鼻涕虫,蛞蝓, and many other forms.Since the problem involves coastal species, simply banning ballast dumps in coastal waters would, in theory, solve it. Coastal organisms in ballast water that is flushed into midocean would not survive. Such a ban has worked for North American Inland Waterway. But it would be hard to enforce it worldwide. Heating ballast water or straining it should also halt the species spread. But before any such worldwide regulations were imposed, scientists would need a clearer view of what is going on.The continuous shuffling洗牌of marine organisms has changed the biology of the sea on a global scale.

The list goes on.Legislation like the Clean Water Act and Wild and Scenic Rivers Act have provided some protection, but threats continue.The Environmental Protection Agency (EPA) reported yesterday that an assessment of 642,000 miles of rivers and streams showed 34 percent in less than good condition. In a major study of the Clean Water Act, the Natural Resources Defense Council last fall reported that poison runoff impairs损害more than 125,000 miles of rivers.More recently, the NRDC and Izaak Walton League warned that pollution and loss of wetlands—made worse by last year’s flooding—is degrading恶化the Mississippi River ecosystem.On Tuesday, the conservation group保护组织American Rivers issued its annual list of 10 ―endangered‖ and 20 ―threatened‖ rivers in 32 states, the District of Colombia, and Canada.At the top of the list is the Clarks Fork of the Yellowstone River, whereCanadian mining firms plan to build a 74-acre英亩reservoir水库,蓄水池as part of a gold mine less than three miles from Yellowstone National Park. The reservoir would hold the runoff from the sulfuric acid 硫酸used to extract gold from crushed rock.―In the event this tailings pond failed, the impact to th e greater Yellowstone ecosystem would be cataclysmic大变动的,灾难性的and the damage irreversible不可逆转的.‖ Sen. Max Baucus of Montana, chairman of the Environment and Public Works Committee, wrote to Noranda Minerals Inc., an owner of the ― New World Mine‖.Last fall, an EPA official expressed concern about the mine and its potential impact, especially the plastic-lined storage reservoir. ― I am unaware of any studies evaluating how a tailings pond尾矿池,残渣池could be maintained to ensure its structural integrity forev er,‖ said Stephen Hoffman, chief of the EPA’s Mining Waste Section. ―It is my opinion that underwater disposal of tailings at New World may present a potentially significant threat to human health and the environment.‖The results of an environmental-impact statement, now being drafted by the Forest Service and Montana Department of State Lands, could determine the mine’s future…In its recent proposal to reauthorize the Clean Water Act, the Clinton administration noted ―dramatically improved water quality since 1972,‖ when the act was passed. But it also reported that 30 percent of riverscontinue to be degraded, mainly by silt泥沙and nutrients from farm and urban runoff, combined sewer overflows, and municipal sewage城市污水. Bottom sediments沉积物are contaminated污染in more than 1,000 waterways, the administration reported in releasing its proposal in January. Between 60 and 80 percent of riparian corridors (riverbank lands) have been degraded.As with endangered species and their habitats in forests and deserts, the complexity of ecosystems is seen in rivers and the effects of development----beyond the obvious threats of industrial pollution, municipal waste, and in-stream diversions改道to slake消除the thirst of new communities in dry regions like the Southwes t…While there are many political hurdles障碍ahead, reauthorization of the Clean Water Act this year holds promise for US rivers.

The passage conveys the impression that_______.A. Canadians are disinterested in natural resourcesB. private and public environmental groups aboundC. river banks are erodingD. the majority of US rivers are in poor conditionText CA classic series of experiments to determine the effects ofoverpopulation on communities of rats was reported in February of 1962 in an article in Scientific American. The experiments were conducted by a psychologist, John B. Calhoun and his associates. In each of these experiments, an equal number of male and female adult rats were placed in an enclosure and given an adequate supply of food, water, and other necessities. The rat populations were allowed to increase. Calhoun knew from experience approximately how many rats could live in the enclosures without experiencing stress due to overcrowding. He allowed the population to increase to approximately twice this number. Then he stabilized the population by removing offspring that were not dependent on their mothers. He and his associates then carefully observed and recorded behavior in these overpopulated communities. At the end of their experiments, Calhoun and his associates were able to conclude that overcrowding causes a breakdown in the normal social relationships among rats, a kind of social disease. The rats in the experiments did not follow the same patterns of behavior as rats would in a community without overcrowding.The females in the rat population were the most seriously affected by the high population density: They showed deviant异常的maternal behavior; they did not behave as mother rats normally do. In fact, many of the pups幼兽,幼崽, as rat babies are called, died as a result of poor maternal care. For example, mothers sometimes abandoned their pups,and, without their mothers' care, the pups died. Under normal conditions, a mother rat would not leave her pups alone to die. However, the experiments verified that in overpopulated communities, mother rats do not behave normally. Their behavior may be considered pathologically 病理上,病理学地diseased.The dominant males in the rat population were the least affected by overpopulation. Each of these strong males claimed an area of the enclosure as his own. Therefore, these individuals did not experience the overcrowding in the same way as the other rats did. The fact that the dominant males had adequate space in which to live may explain why they were not as seriously affected by overpopulation as the other rats. However, dominant males did behave pathologically at times. Their antisocial behavior consisted of attacks on weaker male,female, and immature rats. This deviant behavior showed that even though the dominant males had enough living space, they too were affected by the general overcrowding in the enclosure.Non-dominant males in the experimental rat communities also exhibited deviant social behavior. Some withdrew completely; they moved very little and ate and drank at times when the other rats were sleeping in order to avoid contact with them. Other non-dominant males were hyperactive; they were much more active than is normal, chasing other rats and fighting each other. This segment of the rat population, likeall the other parts, was affected by the overpopulation.The behavior of the non-dominant males and of the other components of the rat population has parallels in human behavior. People in densely populated areas exhibit deviant behavior similar to that of the rats in Calhoun's experiments. In large urban areas such as New York City, London, Mexican City, and Cairo, there are abandoned children. There are cruel, powerful individuals, both men and women. There are also people who withdraw and people who become hyperactive. The quantity of other forms of social pathology such as murder, rape, and robbery also frequently occur in densely populated human communities. Is the principal cause of these disorders overpopulation? Calhoun’s experiments suggest that it might be. In any case, social scientists and city planners have been influenced by the results of this series of experiments.11. Paragraph l is organized according to__________.A. reasonsB. descriptionC. examplesD. definition12.Calhoun stabilized the rat population_________.A. when it was double the number that could live in the enclosure without stressB. by removing young ratsC. at a constant number of adult rats in the enclosureD. all of the above are correct13.W hich of the following inferences CANNOT be made from theinformation inPara. 1?A. Calhoun's experiment is still considered important today.B. Overpopulation causes pathological behavior in rat populations.C. Stress does not occur in rat communities unless there is overcrowding.D. Calhoun had experimented with rats before.14. Which of the following behavior didn‟t happen in this experiment?A. All the male rats exhibited pathological behavior.B. Mother rats abandoned their pups.C. Female rats showed deviant maternal behavior.D. Mother rats left their rat babies alone.15. The main idea of the paragraph three is that __________.A. dominant males had adequate living spaceB. dominant males were not as seriously affected by overcrowding as the otherratsC. dominant males attacked weaker ratsD. the strongest males are always able to adapt to bad conditionsText DThe first mention of slavery in the statutes法令,法规of the English colonies of North America does not occur until after 1660—some forty years after the importation of the first Black people. Lest we think that existed in fact before it did in law, Oscar and Mary Handlin assure us, that the status of B lack people down to the 1660’s was that of servants. A critique批判of the Handlins’ interpretation of why legal slavery did not appear until the 1660’s suggests that assumptions about the relation between slavery and racial prejudice should be reexamined, and that explanation for the different treatment of Black slaves in North and South America should be expanded.The Handlins explain the appearance of legal slavery by arguing that, during the 1660’s, the position of white servants was improving relative to that of black servants. Thus, the Handlins contend, Black and White servants, heretofore treated alike, each attained a different status. There are, however, important objections to this argument. First, the Handlins cannot adequately demonstrate that t he White servant’s position was improving, during and after the 1660’s; several acts of the Maryland and Virginia legislatures indicate otherwise. Another flaw in the Handlins’ interpretation is their assumption that prior to the establishment of legal slavery there was no discrimination against Black people. It is true that before the 1660’s Black people were rarely called slaves. But this shouldnot overshadow evidence from the 1630’s on that points to racial discrimination without using the term slavery. Such discrimination sometimes stopped short of lifetime servitude or inherited status—the two attributes of true slavery—yet in other cases it included both. The Handlins’ argument excludes the real possibility that Black people in the English colonies were never treated as the equals of White people.The possibility has important ramifications后果,影响.If from the outset Black people were discriminated against, then legal slavery should be viewed as a reflection and an extension of racial prejudice rather than, as many historians including the Handlins have argued, the cause of prejudice. In addition, the existence of discrimination before the advent of legal slavery offers a further explanation for the harsher treatment of Black slaves in North than in South America. Freyre and Tannenbaum have rightly argued that the lack of certain traditions in North America—such as a Roman conception of slavery and a Roman Catholic emphasis on equality— explains why the treatment of Black slaves was more severe there than in the Spanish and Portuguese colonies of South America. But this cannot be the whole explanation since it is merely negative, based only on a lack of something. A more compelling令人信服的explanation is that the early and sometimes extreme racial discrimination in the English colonies helped determine the particular nature of the slavery that followed. (462 words)16. Which of the following is the most logical inference to be drawn from the passage about the effects of “several acts of the Maryland and Virginia legislatures” (Para.2) passed during and after the 1660‟s?A. The acts negatively affected the pre-1660’s position of Black as wellas of White servants.B. The acts had the effect of impairing rather than improving theposition of White servants relative to what it had been before the 1660’s.C. The acts had a different effect on the position of white servants thandid many of the acts passed during this time by the legislatures of other colonies.D. The acts, at the very least, caused the position of White servants toremain no better than it had been before the 1660’s.17. With which of the following statements regarding the status ofBlack people in the English colonies of North America before the 1660‟s would the author be LEAST likely to agree?A. Although black people were not legally considered to be slaves,they were often called slaves.B. Although subject to some discrimination, black people had a higherlegal status than they did after the 1660’s.C. Although sometimes subject to lifetime servitude, black peoplewere not legally considered to be slaves.D. Although often not treated the same as White people, black people,like many white people, possessed the legal status of servants.18. According to the passage, the Handlins have argued which of thefollowing about the relationship between racial prejudice and the institution of legal slavery in the English colonies of North America?A. Racial prejudice and the institution of slavery arose simultaneously.B. Racial prejudice most often the form of the imposition of inheritedstatus, one of the attributes of slavery.C. The source of racial prejudice was the institution of slavery.D. Because of the influence of the Roman Catholic Church, racialprejudice sometimes did not result in slavery.19. The passage suggests that the existence of a Roman conception ofslavery in Spanish and Portuguese colonies had the effect of _________.A. extending rather than causing racial prejudice in these coloniesB. hastening the legalization of slavery in these colonies.C. mitigating some of the conditions of slavery for black people in these coloniesD. delaying the introduction of slavery into the English colonies20. The author considers the explanation put forward by Freyre andTannenbaum for the treatment accorded B lack slaves in the English colonies of North America to be _____________.A. ambitious but misguidedB. valid有根据的but limitedC. popular but suspectD. anachronistic过时的,时代错误的and controversialUNIT 2Text AThe sea lay like an unbroken mirror all around the pine-girt, lonely shores of Orr’s Island. Tall, kingly spruce s wore their regal王室的crowns of cones high in air, sparkling with diamonds of clear exuded gum流出的树胶; vast old hemlocks铁杉of primeval原始的growth stood darkling in their forest shadows, their branches hung with long hoary moss久远的青苔;while feathery larches羽毛般的落叶松,turned to brilliant gold by autumn frosts, lighted up the darker shadows of the evergreens. It was one of those hazy朦胧的, calm, dissolving days of Indian summer, when everything is so quiet that the fainest kiss of the wave on the beach can be heard, and white clouds seem to faint into the blue of the sky, and soft swathing一长条bands of violet vapor make all earth look dreamy, and give to the sharp, clear-cut outlines of the northern landscape all those mysteries of light and shade which impart such tenderness to Italian scenery.The funeral was over,--- the tread鞋底的花纹/ 踏of many feet, bearing the heavy burden of two broken lives, had been to the lonely graveyard, and had come back again,--- each footstep lighter and more unconstrained不受拘束的as each one went his way from the great old tragedy of Death to the common cheerful of Life.The solemn black clock stood swaying with its eternal ―tick-tock, tick-tock,‖ in the kitchen of the brown house on Orr’s Island. There was there that sense of a stillness that can be felt,---such as settles down on a dwelling住处when any of its inmates have passed through its doors for the last time, to go whence they shall not return. The best room was shut up and darkened, with only so much light as could fall through a little heart-shaped hole in the window-shutter,---for except on solemn visits, or prayer-meetings or weddings, or funerals, that room formed no part of the daily family scenery.The kitchen was clean and ample, hearth灶台, and oven on one side, and rows of old-fashioned splint-bottomed chairs against the wall. A table scoured to snowy whiteness, and a little work-stand whereon lay the Bible, the Missionary Herald, and the Weekly Christian Mirror, before named, formed the principal furniture. One feature, however, must not be forgotten, ---a great sea-chest水手用的储物箱,which had been the companion of Zephaniah through all the countries of the earth. Old, and battered破旧的,磨损的, and unsightly难看的it looked, yet report said that there was good store within which men for the most part respect more than anything else; and, indeed it proved often when a deed of grace was to be done--- when a woman was suddenly made a widow in a coast gale大风,狂风, or a fishing-smack小渔船was run down in the fogs off the banks, leaving in some neighboring cottage a family of orphans,---in all such cases, the opening of this sea-chest was an event of good omen 预兆to the bereaved丧亲者;for Zephaniah had a large heart and a large hand, and was apt有…的倾向to take it out full of silver dollars when once it went in. So the ark of the covenant约柜could not have been looked on with more reverence崇敬than the neighbours usually showed to Captain Pennel’s sea-chest.1. The author describes Orr‟s Island in a(n)______way.A.emotionally appealing, imaginativeB.rational, logically preciseC.factually detailed, objectiveD.vague, uncertain2.According to the passage, the “best room”_____.A.has its many windows boarded upB.has had the furniture removedC.is used only on formal and ceremonious occasionsD.is the busiest room in the house3.From the description of the kitchen we can infer that thehouse belongs to people who_____.A.never have guestsB.like modern appliancesC.are probably religiousD.dislike housework4.The passage implies that_______.A.few people attended the funeralB.fishing is a secure vocationC.the island is densely populatedD.the house belonged to the deceased5.From the description of Zephaniah we can see thathe_________.A.was physically a very big manB.preferred the lonely life of a sailorC.always stayed at homeD.was frugal and saved a lotText BBasic to any understanding of Canada in the 20 years after the Second World War is the country' s impressive population growth. For every three Canadians in 1945, there were over five in 1966. In September 1966 Canada's population passed the 20 million mark. Most of this surging growth came from natural increase. The depression of the 1930s and the war had held back marriages, and the catching-up process began after 1945. The baby boom continued through the decade of the 1950s, producing a population increase of nearly fifteen percent in the five years from 1951 to 1956. This rate of increase had been exceeded only once before in Canada's history, in the decade before 1911 when the prairies were being settled. Undoubtedly, the good economic conditions of the 1950s supported a growth in the population, but the expansion also derived from a trend toward earlier marriages and an increase in the average size of families; In 1957 the Canadian birth rate stood at 28 per thousand, one of the highest in the world. After the peak year of 1957, thebirth rate in Canada began to decline. It continued falling until in 1966 it stood at the lowest level in 25 years. Partly this decline reflected the low level of births during the depression and the war, but it was also caused by changes in Canadian society. Young people were staying at school longer, more women were working; young married couples were buying automobiles or houses before starting families; rising living standards were cutting down the size of families. It appeared that Canada was once more falling in step with the trend toward smaller families that had occurred all through theWestern world since the time of the Industrial Revolution. Although the growth in Canada’s population had slowed down by 1966 (the cent), another increase in the first half of the 1960s was only nine percent), another large population wave was coming over the horizon. It would be composed of the children of the children who were born during the period of the high birth rate prior to 1957.6. What does the passage mainly discuss?A. Educational changes in Canadian society.B. Canada during the Second World War.C. Population trends in postwar Canada.D. Standards of living in Canada.7. According to the passage, when did Canada's baby boom begin?A. In the decade after 1911.B. After 1945.C. During the depression of the 1930s.D. In 1966.8. The author suggests that in Canada during the 1950s____________.A. the urban population decreased rapidlyB. fewer people marriedC. economic conditions were poorD. the birth rate was very high9. When was the birth rate in Canada at its lowest postwar level?A. 1966.B. 1957.C. 1956.D. 1951.10. The author mentions all of the following as causes of declines inpopulation growth after 1957 EXCEPT_________________.A. people being better educatedB. people getting married earlierC. better standards of livingD. couples buying houses11.I t can be inferred from the passage that before the IndustrialRevolution_______________.A. families were largerB. population statistics were unreliableC. the population grew steadilyD. economic conditions were badText CI was just a boy when my father brought me to Harlem for the first time, almost 50 years ago. We stayed at the hotel Theresa, a grand brick structure at 125th Street and Seventh avenue. Once, in the hotel restaurant, my father pointed out Joe Louis. He even got Mr. Brown, the hotel manager, to introduce me to him, a bit punchy强力的but still champ焦急as fast as I was concerned.Much has changed since then. Business and real estate are booming. Some say a new renaissance is under way. Others decry责难what they see as outside forces running roughshod肆意践踏over the old Harlem. New York meant Harlem to me, and as a young man I visited it whenever I could. But many of my old haunts are gone. The Theresa shut down in 1966. National chains that once ignored Harlem now anticipate yuppie money and want pieces of this prime Manhattan real estate. So here I am on a hot August afternoon, sitting in a Starbucks that two years ago opened a block away from the Theresa, snatching抓取,攫取at memories between sips of high-priced coffee. I am about to open up a piece of the old Harlem---the New York Amsterdam News---when a tourist。

推理英文作文提升方法初中英文:To improve reasoning skills in English writing, there are several methods that I have found helpful. First, reading is essential. Reading a variety of materials such as news articles, fiction, and non-fiction books can expose you to different writing styles and help you understand how authors use evidence to support their arguments. Second, practicing writing is crucial. Writing regularly can help you develop your own writing style and practice using evidence to support your arguments. Third, learning and using logical connectors such as "therefore," "however," and "in addition" can help you connect ideas and make your writing more coherent.To illustrate, I used to struggle with writing argumentative essays because I had difficulty organizing my thoughts and using evidence effectively. However, after reading more and practicing writing, I learned how tostructure my essays and use evidence to support my arguments. Additionally, learning logical connectors helped me transition between ideas and make my writing flow more smoothly.中文:为了提高英语写作的推理能力,我发现有几种方法很有帮助。

逻辑思维锻炼英语作文Title: Enhancing English Writing Skills through Logical Thinking Exercises。
In today's globalized world, proficiency in English writing is increasingly essential for academic, professional, and personal success. However, mastering English writing requires more than just memorizing grammar rules and vocabulary; it demands critical thinking and logical reasoning skills. In this essay, we will explore how logical thinking exercises can significantly enhance English writing abilities.First and foremost, logical thinking exercises stimulate analytical skills, which are crucial for constructing coherent and persuasive arguments in English writing. When confronted with complex issues or topics, individuals need to dissect the information, identify key points, and evaluate their relevance. Logical thinking exercises, such as puzzles, riddles, and deductivereasoning tasks, train individuals to break down problems systematically and derive logical conclusions. These skills directly translate into English writing by enabling writers to organize their thoughts logically, present evidence effectively, and build convincing arguments in essays, reports, or articles.Furthermore, logical thinking exercises fostercreativity and innovation in English writing. While some may perceive logic as rigid and structured, it actually provides a framework within which creativity can flourish. Engaging in exercises that challenge conventional thinking patterns encourages individuals to explore alternative perspectives, devise unique solutions, and express ideas imaginatively. For instance, brainstorming sessions, where participants generate diverse ideas related to a given topic, can inspire inventive approaches to English writing tasks, leading to original content and engaging narratives.Moreover, logical thinking exercises cultivate problem-solving skills, which are invaluable in overcoming language barriers and tackling complex writing challenges. Whenfaced with linguistic obstacles or ambiguity in English writing, individuals equipped with strong problem-solving abilities can effectively navigate through linguistic nuances, resolve grammatical errors, and clarify ambiguous statements. Through exercises that require identifying patterns, making inferences, and drawing conclusions, individuals develop the resilience and adaptability neededto address diverse writing obstacles confidently.Additionally, logical thinking exercises promoteclarity and coherence in English writing by emphasizing the importance of structure and organization. In order toconvey ideas effectively, writers must ensure that their writing is well-structured, with logical progression and coherence from one point to another. Logical thinking exercises, such as sequencing tasks and argument mapping activities, hone individuals' ability to arrangeinformation systematically and maintain coherencethroughout their writing. As a result, writers produce English compositions that are clear, concise, and easy to follow, enhancing readability and comprehension for readers.Furthermore, logical thinking exercises encourage critical analysis of language usage, enhancing individuals' understanding of English grammar, syntax, and semantics. By engaging in exercises that involve identifying errors, analyzing sentence structures, and interpreting meanings, individuals develop a deeper appreciation for the intricacies of the English language. This heightened linguistic awareness directly contributes to improved writing skills, as writers become more adept at selecting appropriate words, constructing grammatically correct sentences, and conveying precise meanings in their compositions.In conclusion, logical thinking exercises play apivotal role in enhancing English writing skills by fostering analytical thinking, stimulating creativity, cultivating problem-solving abilities, promoting clarity and coherence, and deepening linguistic awareness. By incorporating these exercises into language learning curricula and daily writing practices, individuals can effectively sharpen their English writing abilities andcommunicate more confidently and effectively in the global arena.。

M.R.Becwar)S ummaryWell-developed somatic embryos were selected from a repetitively somatic embryo line derived from embryonic axes ofimmature zygotic embryos of English walnut‘No.120’(Juglans regia L.)for germination and conversion studies.Ingerminating dishes,somatic embryos germinated into only shoots,only roots,or both shoots and roots.Without anypretreatment,28%somatic embryos germinated,while those treated with2.5–5.0mg lϪ1(7.2–14.4m mol)gibberellicacid(GA3)germinated at25–28%and those receiving a cold treatment of2–3mo.at3–4ЊC germinated at30–43%.However,only4–19%of the germinating embryos showed both shoots and roots.Treated with desiccation,either withCaCl2·6H2O or Ca(NO3)2·4H2O at20ЊC in the dark for3d,somatic embryos germinated at85–91%,57–69%of whichhad both shoots and roots.Treatment with2mo.cold storage in combination with desiccation using Ca(NO3)2·4H2Oresulted in92%of somatic embryos germinating,70%of which showed both shoots and roots.No significant differenceswere observed between solid and liquid germination media.After transferring the germinating embryos to plantletdevelopment media,52–63%of those with both shoots and roots developed into plantlets while11%with only shoots or9%with only roots converted into plantlets.Plantlet development was improved by using lower medium salts and sucroseconcentrations.The addition of activated charcoal enhanced root development,particularly root branching.Of131plantstransplanted,91plants were acclimatized to a greenhouse.Key words:plant regeneration;Juglans regia;dehydration;synthetic seeds.I ntroductionBiotechnology has been expected to assist plant breeding programs,but applications of biotechnology to plant breeding have frequently been limited by a lack of reliable systems for regenerating transformed plant cells.Somatic embryogenesis has been considered as a useful system for genetic transformation not only because somatic embryos can be induced to repetitively undergo somatic embryogenesis,but also the secondary somatic embryos can be germinated into plants.Successful somatic embryogenesis has already been achieved in various cells,tissues and organs from numerous plant species(Thorpe,1995);however, reports of the recovery of transgenic plants from somatic embryos are rare,partially due to the low efficiency of somatic embryo germination and conversion.In fact,low efficiency of somatic embryo germination and conversion has still remained a significant barrier affecting many of the embryogenic systems described (Merkle et al.,1995).It has been known for some time that treatments of matured somatic embryos with gibberellic acid(GA3),abscissic acid(ABA), chilling,etc.,can induce germination.In Juglans,complete plants have been regenerated from somatic embryos of Juglans regia aftera cold treatment of2–4mo.at2–4ЊC(Tulecke and McGranahan,1985).However,Lee et al.(1988)and Deng and Cornu(1992) obtained a very low conversion efficiency for somatic embryos of Juglans regia and Juglans nigraÂJuglans regia,respectively.Recently,desiccation treatment has been developed for enhancing somatic embryo germination and conversion of Vitis longii(Gray, 1987),Dactylis glomerata(Gray et al.,1987),Glycine max (Hammatt and Davey,1987;Parrott et al.,1988),Carya illinoensis (Wetzstein et al.,1989)and Picea glaucaÂPicea engelmannii (Roberts et al.,1990).Deng and Cornu(1992)have successfully exploited this for promoting the germination of somatic embryos of Juglans nigraÂJuglans regia.Our work was directed to investigate the effect of desiccation on the germination of somatic embryos of Juglans parisons were made with cold storage and GA3treatments.The influences of medium salts,sucrose concentrations,and activated charcoal on plantlet development were also investigated.M aterials and M ethodsSomatic embryo line.A repetitively somatic embryo line,derived from embryonic axes of immature zygotic embryos of English walnut‘No.120’(Juglans regia L.)(Tang et al.,1999a),was used in this study.This line has been maintained by a2-wk interval subculture on a basal DW medium (Tang et al.,1999b)at24ЊC in the dark for more than half a year.The newly formed somatic embryos were isolated and cultured on a basal DW medium 47*Author to whom correspondence should be addressed:Email htang.slfa-nw@agrarinfo.rpl.de48TANG ET AL.for2–3wk prior to germination treatments.Well developed somatic embryos,4–5mm in length,were selected for germination and conversion. Pretreatments to promote germination.1.Cold treatments:Somatic embryos placed on basal DW medium with orwithout0.5%activated charcoal were stored at3–4ЊC in the dark for2–3mo.prior to germination treatments.2.Desiccation treatments:Somatic embryos were placed in empty petri dishes(94Â16mm,20–30embryos each dish).One dish containing somatic embryos along with one80ml beaker containing about50ml of a supersaturated solution of either CaCl2·6H2O or Ca(NO3)2·4H2O was placed in an autoclaved Duran–Schott jar(80Â150mm).The jars were sealed tightly with4–5layers of Parafilm and put at20ЊC in the dark for 3d.At a constant20ЊC,the CaCl2·6H2O created a relative humidity of about32%,the Ca(NO3)2·4H2O about55%(Winston and Bates,1960).3.Cold treatment plus desiccation treatment:Following2mo.cold storageat3–4ЊC in the dark,somatic embryos were treated with a desiccation of Ca(NO3)2·4H2O as described above.Germination treatments.Following pretreatments,somatic embryos were placed on a basal DKW medium solidified with2.2g lϪ1Gelrite(25ml medium per94Â16mm petri dish)or an autoclaved Macherey–Nagel filter compress(85mm in diameter,2layers in a94Â16mm petri dish)soaked with20ml liquid DKW medium.In experiments involving gibberellic acid (GA3,Sigma),a filter-sterilized GA3solution was added to an autoclaved DKW medium solidified with2.2g lϪ1Gelrite(25ml medium per94Â16mm petri dish)to a concentration of2.5or5mg lϪ1(7.2or14.4m mol).The basal DKW medium used contained30g lϪ1sucrose(pH5.5)and was autoclaved at 115ЊC for25min.Somatic embryos without pretreatment were used as controls.Somatic embryos germinated in a growth room set at24ЊC with a16-h photoperiod and a photon flux density of about75m mol mϪ2sϪ1,provided by cool white fluorescent lamps.This experiment was repeated three times with 2–3replicates(individual petri dishes),14–16somatic embryos each,and data were analyzed using Duncan’s multiple range test.Plantlet development.After3wk on germination media,the germinating somatic embryos were transferred to the following six media solidified with 2.2g lϪ1Gelrite(pH5.5)(35ml medium in a175ml baby food jar,four germinating somatic embryos per jar or100ml medium in a1/2l Round–Weck jar,five germinating somatic embryos per jar)for plantlet development.1.DKW 3X0%sucrose;2.DKW 3X0%sucroseϩ0.5%activated charcoal;3.DKW 0X5%sucrose;4.DKW 0X5%sucroseϩ0.5%activated charcoal;5.1a2DKW 0X5%sucrose;and6.1a2DKW 0X5%sucroseϩ0X5%activated charcoal.Plantlet growth was evaluated at4wk post-treatment by measuring their shoot height,numbers of leaves,main root length,roots with branches and numbers of branches.Transplantation of plants.After washing thoroughly with water, complete plants with3–4leaves and well-developed roots were transplanted to plastic pots(11cm in diameter)containing Floration1compost (Floragard᭨GmbH,Germany)(1plant per pot)and watered thoroughly. Plants were then covered with transparent plastic bags and placed in a growth room as mentioned above.Over a3–4wk period,the bags were perforated,then removed.One week later,the plants were moved to greenhouse for further development.R esultsIn germination dishes,somatic embryos first showed an elongation of the root apex and then an emergence of a green shoot.Three types of germinating embryos(only shoots,only roots,and both shoots and roots)were observed and recorded in Table 1.Without any pretreatment,28%of somatic embryos germinated,but only4–6% of them showed both shoots and roots.Treated with GA3,somatic embryos germinated at25–28%,whilst treated with cold storage they germinated at30–43%.However,only5–19%of them had both shoots and roots.Treated with desiccation,either with CaCl2·6H2O or Ca(NO3)2·4H2O,85–91%of somatic embryos germinated and57–69%showed both shoots and roots.Treated with both cold storage and desiccation,somatic embryos germinated about1wk earlier than those with cold storage or desiccation alone and the percentages of the germinating embryos and the embryos with both shoots and roots were significantly higher than those with cold storage(P b0X01)but not significantly higher than those with desiccation.Fig.1illustrates the germination responses of somatic embryos to different treatments after a3wk period.No significantly different germination rates were observed between the solid and liquid germination media except those with cold storage treatments,in which somatic embryos germinated at significantly higher rates in filter compress supported liquid medium than on Gelrite-solid medium(P b0X05).After transferring the germinating embryos into plantlet develop-ment media,those with only shoots resulted in11%plantlets and 50%shoot cultures whereas those with only roots resulted in only 9%plantlets.Between52%and63%of those with both shoots and roots converted into plantlets(Table2).No significantly different conversion rates were found among the six different media;

and roots,as necessary to obtain high conversion rates.It has been reported that ABA accumulates during the maturation of somatic embryos,which induces somatic embryo dormancy (Rajasekaran et al.,1982).Germination cannot take place until the endogenous ABA decreased to an appropriate level.Chilling treatments can markedly reduce the endogenous ABA levels and promote germination (Rajasekaran et al.,1982).Other studies of somatic embryo germination found that the levels of GA 3and GA precursors can increase during the chilling process as ABA levels decrease (Pearce et al.,1987),and exogenously supplied GA 3stimulates germination.In walnut,complete plants have been regenerated from somatic embryos of Juglans regia after a cold treatment (Tulecke and McGranahan,1985).However,our studies showed that somatic embryos of Juglans regia germinated poorly when treated with cold storage alone.The addition of GA 3did not improve the poor germination.Similar results have been reported in Juglans nigra ÂJuglans regia (Deng and Cornu,1992)and Juglans regia (Lee et al.,1988).The ability to obtain germinating somatic embryos is not necessarily an indicator of continued growth and vigor,since plantlets removed from germination conditions often display poor or aberrant subsequent growth and vigor.This might suggest that further post-germination treatments are required.The germination of somatic embryos is often reported,but little mention is made of the continued development of resulting plantlets.McGranahan et al.(1987)reported that the root growth of the germinating somatic embryos of Juglans regia was improved by transfer to a simple White medium with lowered sucrose and added charcoal.This is in agreement with our results that plantlets grew much better on the half-strength DKW medium with a lowered sucrose concentration than on the full-strength DKW medium.The addition of activated charcoal aided plantlet growth in root development,especially by promoting root branches,which resulted in plantlets with more vigor.The use of lower medium salts during plantlet development might suggest that different stages of plant development may require different types or concentrations of basal salts.A cknowledgmentsThe authors thank Baumschule Anton Schott,Leiselheim am Kaiserstuhl,Germany for
