5. Unit 5: Writing PracticeSample Essay:In recent years, the use of smartphones has become increasingly prevalent. They have transformed not only the way we communicate but also the way we live our lives. However, some people argue that smartphones have had a negative impact on our society. In this essay, I will present both the advantages and disadvantages of smartphone use.On the positive side, smartphones have greatly enhanced our ability to connect with others. With just a few taps on a screen, we can instantly communicate with friends and family around the world. This has made it easier to maintain relationships and stay connected, even when we are physically apart. Additionally, smartphones provide access to a vast amount of information. With internet connectivity, users can quickly search foranswers to their questions, making learning and problem-solving more convenient.Yet, there are also drawbacks associated with smartphone use. One major concern is the negative effect on interpersonal communication. People are increasingly engrossed in their devices, leading to less face-to-face interaction. This can result in a decline in social skills and a lack of genuine connections. Moreover, smartphone addiction has become a serious issue. Many individuals find it difficult to detach themselves from their devices, leading to decreased productivity and increased stress levels.In conclusion, smartphones have undoubtedly revolutionized our lives, bringing numerous benefits. However, it is important to recognize and address the potential drawbacks. Finding a balance between utilizing the advantages of smartphones while mitigating their negative impact is crucial. By doing so, we can fully harness the power of technology while preserving the essence of human connection.。

They are eager to lead a life that is less stressful intellectually and less pressing economically. In their eyes, they could get a decent job without higher education.However, some students plan to continue their education. They find that the knowledge and skills acquired at secondary level of education are far from adequatein the job market. It is a fact that an ever-increasing number of graduates are returning to school, motivated by the need to update their knowledge and enhance their skills.All this indicates that lack of higher education can hardly qualify students for a competitive position. If I were able to choose for myself, I would prefer to stay and continue my education. I know my choice would mean a commitment of time and money. Opportunities, however, always take the form of hardships and risks. The days might be rigorous and painstaking, but they would certainly be fulfilling and rewarding, and would surely lead to a prosperous future.Unit2Text AI. 1-5 DACBBII Section A1. effectively2. response3. discover4. occur5. rare6. scientificSection B1. remove2. eventually3. opportunity4. renowned 6. remarkSection C1. to2. so3. to4. on5. in6. forIII. 1. fear 2. under 3. unavoidable 4. success 5. without6. reach7. between8. so that9. as long as 10. wiselyText BI Section A .1.

WritingSection CThe Most Important way to successAs a well- known proverb goes, “Where there is a will, there is a way”, which means that one can find a way to success as long as he or she has a strong will. With a strong will, one can focus all his energy on one point, which makes his success possible. Without a strong will, however, one can be easily distracted from his goal or discouraged by setbacks.History abounds with examples of strong-willed figures winning success. Look at the deeds of Gou Jian, king of Yue in ancient China. Defeated by Fu Chai, king of Wu, Gou tried every possible ins to steel his will. Eventually, with the help of Fan Li and Xi Shi, he managed to rebuild his country and his armies and had Fu Chai taste the bitterness of failure.In short, a strong will is the most important way to success. One should lose no chance to strengthen his will and remember: God helps those who help themselves.Unit 3Text AI. 1-5 A B B A BII．Section A1. recognition2. reflection3. undisputed4. loyalty5. essential6. assuranceSection B1. sought2. requested3. challenge4. mutual5. virtue6. generationSection C1. of2. in3. of4. of5. through6. inIII1.

WritingSection CWhen I graduate from college, I may not commit myself to a lifetime career, because I don' t know whether I can find the job of my dreams upon graduation, which I' m determined to spend my whole life on it. I think there are advantages of job-hopping.For newly minted college graduates, job-hopping can speed career advancement. Changing jobs and getting a promotion in the process allows employees to avoid the "dues paying" that can trap workers in a painfully slow ascent up the corporate ladder. Job hopping can also lead to greater jot fulfillment, because it means trying out a variety of roles and workplaces while learning new skills along the way.People often think today' s young workers like us change their jobs too often, and they lack the patience to settle down. Actually, we are more concerned than our predecessors with finding happi-aess and fulfillment in our work lives. Indeed, since humans have been proven to be terrible at pre-dicting what will make us happy, it's crucial that we find it through trial-and-error.Keys to Self-Assessment 1第一部分1-10 C B B C B B C A A A第二部分11-15 D B D C A第三部分Task 1 16-20 E A F B CTask 2 21-25 B E D C A第四部分26-30 F A D C B H第五部分31-40 H D C K L F E J B第六部分41. encourage 42 careful 43. particularly 44. implication 45. trained46. impression 47. communication 48. respectful 49. designer 50. logical第七部分WritingI'm very glad to have won the first place in the English Speech Contest.

At first, I have a good job with high salary, much more free time and fine environment. Thus, I have enough money to buy a car, a beautiful and comfortable house. What's more, I travel around the world in holidays. Second, I have a husband who loves me very much. He has a sense of responsibility; he concerns about me, encourages me, believes me and sup-ports me in life. We understand and love each other; we live a simple but happy life. Third, a family is full of laugh. Parents keep a healthy body; we live together all the time, so they never feel lonely. In addition, I often communicate with my child who is smart and considerate, and we are just like friends.

They are crazy for everything prevailing in society, from clothes to luxurious mobile phones. The reasons behind such a phenomenon can be summarized as follows. First, college students are open-minded and are willing to accept new things, so pursuing famous brands well reflects their pioneering spirit. Second, in modern society, famous brands mean fashion to some extent, which has drawn college students' attention. What' s more, some students were spoiled when they were children , which lead to such a terrible consumption habit. As far as I am concerned, college students should have the pioneering spirit. However, the spirit cannot be reflected in pursuing fashion, but in their great academic achievements. What they should do is to put determined efforts into studying to achieve better academic performance, instead of more expensive famous brand products.Unit 7.Text AI. 1-5D C B A A1. precisely2. hesitate3. wonderful4. emotion5. ignorance6. completeSection B1. attached2. attempts3. upset4. overwhelming5. prompt6. innerSection C1. took2. with3. for4. took5. in6. withIII1. choose2. opportunity3. view4. accordingly5. end up6. interact7. night8. what9. nonstopText BI SectionA.1.

However, in such a dilemma, quite a few graduates still choose to go back home. Well, they have their own reasons such as to complete their original dreams, to help build their hometowns, and to reunite with their families.As the Chinese old saying goes, what comes from the soil will return to the soil; falling leaves will settle on the root. Looked forward to your reunion with parents, longed for your intelligence to help develop your hometown, besides the job-hunting issue, upon the graduation it' s certainly better to go back to hometown than to stay in big cities.Unit 8.Text AI. 1-5 C C D B AII Section A1. perfection2. accomplishment3. persistent4. disposal5. effective6. motivationalSection B1. obstacle2. incredible3. vision4. perspective5. fulfill6. profoundSection C1. from2. in3. for4. at5. in6. ofIII1. confused2. natural3. intensionally4. likely5. potential6. called upon7.

Meanwhile the number of Chinese students especially the younger students studying abroad has been growing dramatically in recent years.What has brought about the huge growth That must be the result of the interaction of many factors! First of all, the United States has the world' s most advanced educational resources, you can never get this level of quality in China. Now more and more people are beginning to discover the benefits of quality education, so they send their children to the US. Second, more and more Chinese begin to accept western culture. There' s no doubt that studying abroad is a good way to learn it. Third, the Chinese begin to get rich. This is the direct cause of this phenomenon.Obviously, the US can provide the best education in the world. Thus, with the growing of fees, the authorities should enhance some policies to ensure the equity of education.Unit 9.Text AI．1-5 C C A C AII.

We will benefit a lot if we treat the difficulties as challenges and opportunities rather than threats. They are two different attitudes towardslife. The former reflects we have a positive mind and we want to solve all those problems, while the latter means we have a negative mind and do not have courage to face difficulties. Therefore, I think challenges play an important role in our life. They require us to improve ourselves constantly, so we will become stronger in the process of taking challenges.But, how should we prepare ourselves to meet challenges First, we should have a right attitude towards difficulties, which are opportunities to test our abilities rather than enemies who want to defeat us. Second, we should always believe ourselves. God helps those who help themselves. No one in the world should believe you more than you do. Finally, enjoy the pleasure of solving problems and overcoming difficulties. Real happiness comes from hard-won achievements. Difficulties and challenges are our friends who help us in our way to become a stronger person.Unit 10Text AI. 1-5 A B D D CII.

But it also brings the government a new problem, because too many young workers need to take the buses to work at rush hour. Then, some people suggest canceling the free ride for seniors at rush hour.I strongly disagree with the suggestion because it is a symbol of social progress to show our care and concern for seniors.No matter whether the government provides free bus travel for seniors or not, the demands for traveling won't decrease. The key to alleviate the traffic jam relies on more public transportation, wider roads and fewer private vehicles. We could encourage citizens to go to work by riding their bicycles or walk to work if the distance is not too far, which is also a good chance to exercise at the same Be. Also it is advisable for the seniors to avoid going out at the rush hour.In my opinion, we can go on giving due respect to seniors, but at the same time, the government should come up with more efficient ways to solve the problems of traffic jam rather than just cancel the free bus travel for seniors.Unit 11Text AI. 1-5 A D B A CII Section A1. merely2. intimate3. determine4. romantic5. perception6. intenseSection B1. convey2. revealed3. variety4. suspected5. potential6. personalitySection C1. to2. under3. as4. in5. of6. toIII1. everywhere2. get up3. enjoy 5. while6. daily7. since8. in touch with9. use 10. communicateText BI.

My best friend, Tom, has become addicted to online chat rooms and games for a while and our friendship has started to suffer. Here are my plans to maintain our friendship;On the one hand, I have signed up for us in a music club. My friend is a great fan of the Beatles. If there is a chance for him to join in a music club, he would be more than happier to accept. Then, he would be fully occupied by the schedule of the music club instead of being distracted on the Internet only.On the other hand, people can actually make friends and air their views freely online. When they feel frustrated, they may talk with a stranger online rather than with their parents or friends. When the chat is over, they feel contented and refreshed. Being a great friend of his, I will apply for a new account to contact him. Considered as a strange person, I can find his problems more easily and help him to solve them in certain ways.With my patience and accompany, Tom will eventually realize that online chatting is a waste of time. We can try to reduce the negative effects to the minimum and make online chatting our valuable assistant.Unit 12Text AI 1-5 A D B A BII Section A1. awareness2. resemblance3. permission4. emotional5. settlement6. justificationSection B2. manufactured3. refreshing4. empowered5. symptom6. nurturedSection C1. up2. with3. to4. away5. out6. setIII1.

Having a positiveself-image can give you the self-confidence that you need to get a better job, try new things and it will give you a general overall feeling ofwell-being.Another advantage of plastic surgery is the ability to correct physical defects. Some people are born with physical defects that have plagued themsince birth and cosmetic surgery can finally give them a shot at a normal life.If you are in good general health and decide that cosmetic surgery is something that you want to do, do research on the particular procedures that you are interested in so that you know what you are getting into.

Then you are able to make an informed and responsible decision.All in all, the advantages of cosmetic surgery can outweigh the risks if it can change your life for the better. Everyone deserves to look their best.Self- Assessment 3第一部分1-10 A C A B A B B B A A第二部分11-15 A B C A D第三部分Task 116-20 B D A F ETask 221-25 B D C A E第四部分26-30 F C E B A第五部分31-40 B F G D A J L I K E第六部分41. dissatisfaction 42. balanced 43. healthy 44. vigorous 45. shamed46. failure 47. perception 48. comfortable 49. impossible 50. fulfilled第七部分WritingIs Internet a Blessing or a CurseIn recent years the Internet has been wildly used for studying, contacting, shopping and many other things.

1.In paragraphs 1 and 2, the author tells a story about a professor in Robert A. Fowkes‟s class. What was strange about the professor?A:First, the professor said “ladies and gentlemen,” while ther e was only one student. Second, Robert A. Fowkes, th e only student in class, missed one class, but the professor didn‟t give the lecture Fowkes had missed, but gave the next one in the sequence.2.Why was the lecture system popular in the thirteenth century?A:In the 13th Century books were so rare and expensive that few students could afford them.3.In paragraphs 5–7, what does the author use an imaginary class to show us?A;The author uses an imaginary class to show us the inadequacy of the lecture system.4.In the imaginary class, what makes Mary and other students bored?A:The way the professor lectures: He is just reading from a stack of his very old notes.5.Why do Mary and her fellow students stick it out while some drop out of college?A:Mary and some other students become resigned to the lecture system and wait to become juniors and seniors. Then, they will attend smaller classes and at last get the kind of personal attention that real learning requires.6.In paragraph 10, the author discusses active learning and passive learning. Give some examples of both.A:Active learning: Students write essays, do experiments and then have their work evaluated by their instructors. Passive learning: Attending lectures.7.In what way do most students learn best?A;Most students learn best by engaging in frequent and even heated debate.8.According to paragraph 13, why do administrators love lectures?A;They can cram a lot more students into a lecture hall than into a discussion class.9.Why may smaller classes be exhausting to the teacher?A;Smaller classes may require energy, imagination, and commitment from the teacher, which can be very exhausting.10.According to the author, who should receive more lectures?A;Juniors and seniors.1.In paragraph 1, the author says that we are in the middle of a sixth great extinction. What are these great extinctions? Could you name some. In what way is the current great extinction different from the previous five ones?A;The difference lies in the fact that the previous five great extinctions have occurred for natural causes, but the current great extinction has been caused by human activities.2.What is the author trying to do with paragraph 2?A;The author gives us some examples to show what human needs have caused the current great extinct ion. Generally speaking, they are humans‟ needs for survival.3.Why did the buffalo and the passenger pigeon in North America become extinct?A;Both the buffalo and the passenger pigeon became extinct owing to overhunting by humans.4.What point does the author want to illustrate by writing about the European rabbits in paragraph 4?A;He wants to illustrate that natural habitats of some native species could be destroyed by the introduction of foreign species. The introduction of European rabbits into Australia is a good example. They multiplied quickly and threatened the habitat of native grazing animals in Australia by eating all the vegetation.5. In paragraph 5, the author states that humans endanger other species by destroying their natural habitats. What example does the author give to support this statement?A;The example is: The rapid shrinking of rainforest caused the loss of many species that made their homes in it.6. What can we learn from paragraph 8?A;Each life form occupies a special place in the ecosystem, and the disappearance of any species will affect other species in the ecosystem. But 74 species are dying out every day.7.What are the two advantages that biodiversity has over monocultures according to paragraphs 9–12?A;1) Biodiversity makes it possible for useful substances to be found in species we haven‟t got to test or study.2)Biodiversity will save humanity from being starved to death owing to their great dependence on a small number of species.8.In paragraph 10, the author writes about the Pacific yew tree. What makes the Pacific yew tree so highly valued today? What does the author want to tell us by mentioningthis tree? A;Because it is discovered that the bark of the Pacific yew tree contains a substance called taxol, which can effectively treat certain kinds of cancer. By mentioning this tree, the author wants to tell us that many species may die out before their value is discovered.9.What is the main idea of paragraph 11?A;Paragraph 11 mainly tells us that the value of the vast majority of species has yet to be discovered. It is very important for us to protect the diversity of species. If we don‟t, we will lose species that may turn out to be extremely important to our own survival.10.What point is suggested by the last paragraph?A;It suggests that it‟s hard to tell whether these protective methods will be effective or not now because the rapid human population growth may make it difficult to put these methods into practice.Unit51.At the beginning of the article, the author declares that, in order to solve the current confusion about the proper roles that men and women should play in marriage, he proposes to establish new marital norms. What pattern of marriage behavior does he propose? Is this pattern a traditional one or a brand new one?A;He proposes a pattern of late marriage followed by a modified traditional nuclear family in the early childrearing years. It is mainly a traditional pattern but with some changes.2. According to the first principle proposed by the author, should women be well-educated and work outside the home after marriage? Is this a traditional or modern idea?A;Yes. The author says women should be well educated and be trained according to their abilities for a socially useful paid job or career. Everyone should make work contribution in their lifetime. This is a modern idea.3. What is the second principle the author proposes? Is this a traditional or modern idea? A;The second principle is that young people should hold the expectation that they will marry only once and for a lifetime and that they will have children. This is a traditional idea.4. According to the third principle, what is the best age for marriage? Why? In addition, what‟s the possible result of late marriage? Is the author for or against this way of life? How do you know?A;The best age for marriage is late twenties or early thirties, or even later for men. The reason why society encourages people to marry relatively late in life is that at that time they are more mature, know better what they want in a mate, and are more established in their jobs or careers, and men have begun to have more stable sex life with a permanent sexual partner, all of which help reduce the risk of divorce. The reason why individuals, both women and men, also want to marry later is that they want to have time to pursue personal expression and fulfillment before marriage. One possible result of late marriage is long years of nonmarital cohabitation in young adulthood. The author is for nonmarital cohabit ation, but on the condition that it is associated with “serious, caring relationships,” not “sexual promiscuity”, because he writes that this is “an arrangement that often makes more sense than the alternatives to it,” meaning it is more sensible than livi ng alone ith one‟s parents.5.According to the fourth principle, what is the disadvantage of late marriage? How to overcome it?A;The disadvantage of late marriage is that, as people live a single life for 10 years or even more, they tend to be more eager to fulfill themselves, less willing to carry out family responsibilities, and therefore find it harder to adapt to marriage and childrearing. To overcome this disadvantage, young unmarried adults should be encouraged to save a large part of their income for a family fund, which will be used when the wife quits working outside and stays at home as full-time housewife after marriage and childbirth.6. From children‟s birth to their early or middle teen years, what childrearing arrangements does the fifth principle recommend to the parents? Is this strategy known as “sequencing” a traditional or new practice?A;This practice is mainly traditional but with some modifications, such as mothers‟ working parttime after the child is 3 years old or fathers‟ becomi ng the primary caretaker after the child is 18 months old if they wish.7.For women, it seems that the conflict between childcare and career development is unavoidable. To the author, which of the two is more important? What should the government do to make up to women for their career loss?A;To the author, childcare is more important since he says “it is possible to …make up‟ for career loss, but impossible to make up for child-nurturing loss.” He urges that the government institute parental leave and child allowance programs for families with young children to live on a single income, and develop “veterans benefits” type of programs that provide mothers with financial subsidies and job priorities when they return to the paid work force.8. According to the sixth principle, while the mother is ordinarily the primary caretaker of the infant, what domestic work should the father do? And after the infant is 18 months old, is any change possible to the father‟s role? Here is the father assuming the tradition al marital gender role or a new one? What should employers do accordingly to adapt to this situation?A;The father should be an active supporter of the mother-child bond as well as an auxiliary homemaker and care provider. He should take care of the house, yard and car and in many cases cook meals, clean the house, look after the child, etc. if he has the skills and talents. After the child reaches 18 months, it is possible that the father becomes the primary caretaker. Here the father is assuming a new role of auxiliary homemaker and care provider in addition to the traditional role of breadwinner. Accordingly employers must allow not only mothers but also fathers to be absent from work frequently while taking flex-time and part-time jobs because fathers also have to care for the children.9. As the seventh principle implies, will the situation last throughout their marriage that women do more domestic work and less paid work than men?A;No. In the earlier marriage life women will do more domestic work than men, but in thelater marriage life women will do more paid work than men partly because husbands, being older, will retire earlier than their wives and partly because due to hormonal changes, women become more work-oriented and men become more home-oriented in later life.10. In conclusion, in the author‟s opinion, which should have a higher priority for men and women in modern society, personal pursuits or parenting? For the benefit of both society and individuals, is it sensible to completely abandon the marital roles of men as the breadwinner and of women as the homemaker and childrearer associated with the traditional nuclear family? What marriage behavior does the author disapprove of? What marriage behavior does he advocate?A;During the parental years, parenting should have a higher priority over personal pursuits. Parents should limit their expressive freedom for the welfare of children.No, it is foolhardy to do so. When there are young children in the family, if the traditional marital gender roles are abandoned, then society will be in danger.The author disapproves of the “strive for androgyny”, that is, people struggling to play both the male breadwinning role and the female childrearing role at the same time. He advocates that people acknowledge, accommodate, and appreciate the different needs, interests, values and goals of different sexes.He disapproves of the “unisex pursuit of freedom with a male bias”, that is, both men and women pursuing freedom (success and fulfillment in career) that is traditionally possessed by men. He advocates that people give more importance and respect to family bond and childcare that are traditionally valued by women. By this, he suggests that the traditional division of labor is still nece should go on playing the traditional female childrearing role during the child-nurturing years.。
