美国梦对不同的人有着不同的含义。
但对许多人，尤其是对移民而言，它意味着改善自己生活的机会。
对于他们，美国梦的含义就是才能与勤劳能让你从小木屋走向白宫。
托尼·特里韦索诺并没有爬那么高，但他成功地使自己的梦想成真。
托尼·特里韦索诺的美国梦弗雷德里克·C·克罗弗德他来自意大利罗马以南某地的一个遍地是石头的农庄。
他什么时候以及怎么到美国的，我不清楚。
不过，有天晚上，我看到他站在我家车库后面的车道上。
他身高五英尺七、八左右，人很瘦。
“我割你的草坪，”他说。
他那结结巴巴的英语很难听懂。
我问他叫什么名字。
“托尼·特里韦索诺，”他回答说。
“我割你的草坪。
”我对托尼讲，本人雇不起园丁。
“我割你的草坪，”他又说道，随后便走开了。
我走进屋子，心里有点不快。
没错，眼下这大萧条的日子是不好过，可我怎么能把一个上门求助的人就这么打发走呢？等我第二天晚上下班回到家，草坪已修整过了，花园除了草，人行道也清扫过了。
我便问太太是怎么回事。
“有个人把割草机从车库里推出来就在院子里忙活起来，”她回答说。
“我还以为是你雇他来的。
”我就把前晚的事跟她说了。
我俩都觉得奇怪，他怎么没提出要工钱。
接下来的两天挺忙，我把托尼的事给忘了。
我们在尽力重整业务，要让一部分工人回厂里来。
但在星期五，回家略微早了些，我又在车库后面看到了托尼。
我对他干的活夸奖了几句。
“我割你的草坪，”他说。
我设法凑了一小笔微薄的周薪，就这样托尼每天轻扫院子，有什么零活，他都干了。
我太太说，但凡有重物要搬或有什么要修理的，他挺派得上用场。
夏去秋来，凉风阵阵。
“克罗先生，块下雪了，”有天晚上托尼跟我说。
“等冬天到了，你让我在厂里干扫雪的活。
”啊，对这种执着与期盼，你又能怎样呢？自然，托尼得到了厂里的那份活儿。
几个月过去了。
我让人事部门送上一份报告。
他们说托尼干得挺棒。
一天我在车库后面我们以前见面的地方看到了托尼。
“我想当学徒，”他说。

Firstly, it offers convenience. With just a few clicks, people can purchase items from the comfort of their own homes. This saves time and eliminates the need to travel to physical stores.Secondly, online shopping provides a wider variety of products. Customers have access to a global market and can choose from a vast range of items, including those that are not available in local stores. This gives shoppers more options to find the exact product they are looking for.Additionally, online shopping often offers better prices. Many online retailers offer discounts and promotions, allowing customers to find great deals. Furthermore, customers can easily compare prices between different websites to find the best value for their money.Disadvantages:Despite its benefits, online shopping also has some disadvantages. One major concern is the lack of physical inspection. When shopping online, customers cannot physically examine or try on products before purchasing them. This can lead to disappointment if the product does not meet their expectations.Another drawback is the potential for fraud and security risks. As online transactions require the sharing of personal and financial information, there is a risk of that information being stolen or misused. This can lead to financial loss and identity theft.Lastly, online shopping lacks the immediate gratification of traditional shopping. Customers have to wait for the product to be delivered, which can take several days or even weeks. This delay may not be suitable for individuals who need immediate access to the item.In conclusion, online shopping offers convenience, a wide variety of products, and better prices. However, it also has drawbacks such as the lack of physical inspection, potential for fraud, and delayed gratification. It is important for consumers to weigh both the advantages and disadvantages before making a decision to shop online.第七课综合填空1.respected2.encourage3.opportunities4.beginner’s5.interaction6.featuring7.techniques8.workshop9.improve10.participated第八课作文题目：Describe your favorite hobby and why you enjoy it.My favorite hobby is playing the guitar.

Unit 4 Lierature and ArtsText A 参考译文诗，如同这世界，可以说是有四个时代的，不过程度不同罢了；诗的第一个时代是铁器时代、第二个是黄金时代；第三个是白银时代；第四个是黄铜时代。
在诗的第一个时代，铁器时代，粗野的歌人，用震耳的旋律，歌颂更粗野的魁酋们的丰功伟业，当时，人人都是战士，各式社会的最高实践箴言是：“保持我们所有的东西，夺取我们所能夺取。
”，这箴言尚未以正义的名义和法律的形式装扮起来，而是刀光剑影的一句露骨格言，白刃相向就是meum et meum(而我之间)一切问题的裁判和公断。
在那些日子，只有三种职业兴隆（除了时时都兴隆的祭司职业以外），那就是王者、盗贼、乞丐的职业：乞丐多半是穷途落魄的王者，盗贼则多半是前途似锦的王者。
向一个陌生者询问的第一个问题是：“你是乞丐还是盗贼?”陌生人回答，往往先冒充乞丐，等到方便时机，便证明他堪称为盗贼。
每个人的自然欲望，是把他所能获得的权势和财产，尽量独占为己有，不择手段，强权就是公理；加上一个同样自然的欲望，那就是让尽可能多的人知道，他在这个普遍追求中夺得多少东西。
成功的武士变成魁酋，成功的魁酋转成王者：他接着便需要一个工具来宣扬他的功业的名声和财富的多寡。
这个工具他在歌人身上找到了，歌人事前在他的美力充分感发之下，是随时准备歌颂他的武力的。
这就是诗的起源：诗，正如其他职业那样，是因有这种商品的需求而兴起，按照市场范围的扩大而繁荣的。
所以，诗在起源时是歌功颂德的。
各民族最早的粗野诗歌，好像是一种简要的历史介绍，用臃肿浮夸的调子，颂扬一些杰出人物的功绩和财产。
诗的黄金时代取材于铁器时代。
这个时代开始之时，诗便开始回顾往事，一种类似扩大的国家行政体系的制度已经建立起来，个人的力量和勇敢已经不足以扩张武人勇士的势力，不足以使帝王废立和国家兴亡了，有组织的人群，社会的制度，世袭的继承等等，将予以抑制。
人们也更多生活在真理光辉之中，交换着观察成果，从而看出了鬼神的作用不是那么经常在他们之间发生，从古代诗歌和传说看来好像经常在他们祖先之间发生似的。

V. Keys to the ExercisesFocusing on ReadingTask 1Task 21) First, to understand the effect of GM crops on us and animals; second, to provide investigation intothe influence of GM crops on mammals, especially on their reproductive function.2) Because it is known that raw soybean contains a number of anti-nutrients and female hormone-likesubstances, a positive control group was created to guarantee the validity of the study.3) The major findings are: first, the mortality rate of the pups from the GM soya group was muchhigher and this high rate continued; second, the weights of the surviving rat pups were lower.4) Table 4 shows the weight distribution of the pups which reveals a much lower weight of the pupsfrom the GM soya group.5) Firstly, the transformation and the insertion of the foreign genes into the sexual/stem cells, or/andinto cells of the fetus. Secondly, the accumulation of Roundup residues in GM soya residues couldproduce negative effects of GM.Task 31) j 2) i 3) g 4) b 5) e 6) f7) c 8) s 9) d 10) q 11) w 12) x13) u 14) o 15) t 16) v 17) a 18) r19) h 20) n 21) m 22) p 23) k 24) l Task 4The most formal ones are: novel, stunt, impede, curb, hamper, allocate, dispense, persist, accumulate,presume, postulate, surmise, detrimental, pernicious, jeopardy, menace, perilTask 51) Therefore, we decided to carry out a study to see how the most commonly used GM crop affectedthe birth rate, death rate and weight gain of rat pups whose mothers were fed diets added withRoundup-Ready soya, a kind of GM food.2) This fact showed that the pups from the GM group were the same age as others, but changesappeared with the development of internal organs. A slight bad effect was found in the group withthe traditional soya, but this effect was not very important.3) The more surprising thing was that the pups were smaller, about half the size, so more milk shouldhave been given to the individual pups. They should have a better chance to grow best, unless theamount, and/or the quality of the milk, were not affected by eating the GM soya flour.Task 6Summary: GMO, with foreign genes from other species, displays certain novel characteristics andundergoes criticisms from scientists worldwide.Task 7Four major sources of the hazards of GMO have been discussed by scientists worldwide and thesehazards have been proved in many investigations. This study intends to f ind the effect of the mostcommonly used GM crop on the birth rate, mortality and weight gain of rat pups. Two weeks before their mating, three groups of rats which were sexually mature received respectively standard laboratory feed, feed supplemented with traditional soya and feed supplementedwith GM soya.It has been found that the GM soya group has a much higher rate of pup mortality than the other twogroups, and the pups continue to die over the period of lactation. This group also has lower weights.Task 8(omitted)Task 9(omitted)Task 10(omitted)Research Paper WritingTask 11) The methods section of Text 4 contains two parts: participants and procedure. The participant parttells the reader the participants (Wistar rats) and the number of rats used. The procedure part givesthe reader a summary of each step in the execution of the research.2) The writer divided the rats into three groups: the experimental group, the control group and thepositive control group. The division was intended to see how the GM crops inf luence the birth rate,mortality and weight gain of rat pups.3) Each step was made clear to prove the validity and reliability of the results and conclusion.

Snedecor, in honor of Sir Ronald A. Fisher, an English statistician knownfor his important contributions to statistics, including the analysis of variance. P stands for probability.They should be reported to show whether the difference in the means was statisticallysignificant.Task 9Past tense is used in the results section because the results were collected from the data in theexperiment.Task 10Similarity 1: Both sections use tables to report the data clearly and insert titles on the top of the tables.Similarity 2: Both sections use the past tense to present the data.Similarity 3: Both sections are concise and well-organized.Similarity 4: Paragraphs in both sections begin with an opening sentence telling the reader the aim ofthe experiments.Task 11Title: The number of different types of words recalled in different background music conditionsTask 12Table 1 The effects of time limit and television exposure on reading comprehensionTask 13—From the data it is evident that 36% of ...—The study of ... showed that ...—This fact indicated that ...—A slight negative effect was found in the group which ...—A very high rate of ... was observed in the group of ...—The subjectively estimated prevalence ... was somewhat greater for ... than for ... —Three manipulation-check questions indicated that ...—This survey of ... found that ...—A possible explanation for this finding may be ...—A one-way analysis of variance showed no significant effect of ...—Another one-way ANOVA indicated a significant effect of ...—... with no significant difference between the latter two groups.—No significant effect was found for ...—Unexpectedly, ... had no significant effect on ...—Unexpectedly, ... did not significantly affect ...Task 14shows; were; was; was; stopped; was; suggests; isTask 15(omitted)Academic Survival SkillsTask 1An academic essay is considered formal professional communication, with its primary goals asaccuracy, clarity and completeness. To achieve this style, formal language and clear organization shouldbe adopted. The language used in the article bears the following characteristics:1) Use formal words rather than verb phrases;2) Use long and complex sentences with clauses, nominal phrases;3) Avoid using f irst person or second person pronouns to achieve objectivity;4) Avoid using contractions.Task 21) Failure to protect the environment will cause children to suffer the most.2) These problems need to be addressed.3) However, endangered animals are available in many restaurants.4) Participating in social activities as volunteers can be of great significance to children.Task 3By comparing the above pairs of sentences, we can f ind the functions of nominalization. First, nominalization avoids the use of modal verbs (can, may, etc.), giving more logic to the statement;second, nominalization depersonalizes the statement by avoiding using first and second-personpronouns (I, you, we, etc.), making the writing impersonal and objective and increasing thecredibility; third, nominalization makes the sentence concise and succinct, thus easier for the readerto understand.Task 41) The model provides an explanation for the figure fluctuation in this period.2) But those skills can f ind their application in the exploration of the universe.3) The accidental release of radiation caused damage to a wide area for a long time.4) To obtain most readers’ acceptability and more profitability, the novel follows the most commonlyaccepted notions of morality and justice.5) The richness of the soil in this area contributes to the quick growth of the crops.6) The information explosion and the increasing obsolescence of knowledge are forcing upon highereducation a new set of demands.7) The times give signs on the necessity of modification in the legal system.8) The careful supervision of the crops is necessary for their survival at harvest time.9) Yet all of history has taught us that the denial of these ultimates and the placement of man at thecore of the universe will lead to mass selfishness.10) The knowledge of its sources and symptoms provides rational analysis of many things. Task 51) How we view the world is a reflection of how we view ourselves, and this gives us insight into ourinner thought patterns.2) That does not eliminate the need for us to continue to develop other clean energy sources like solar,wind, biomass, etc.3) Some analysts worried that the tax on the wealthy would discourage jobs creation and hampereconomic growth.4) This meeting highlights the importance of setting targets for progress.5) Too much criticism undermines the children’s co nfidence.Task 61) The opportunities offered by urbanization must be taken full advantage of.2) However, little control is exercised over online articles and speeches.3) The main effects of poverty can be illustrated by looking at those on the lowest incomes in richcities.4) Obviously, people were given jobs according to whether they were male or female.5) Although there are potential benefits of such techniques, the potential environmental and medicalconsequences of GMOs are seriously concerned about.6) A fairly consistent picture of its short-term effects on users in many publications are presented.7) Not much has been learned about the acute physiological effects of cannabis.8) People’s concerns can be understood if we look at the current anti-discrimination laws.9) The distinction between government policy and economic reality is made clear in the essay.10) Social conditions as well as the economic situation should be taken into account. Task 7I would prefer to use the ones in the left column.Task 81) Systems analysts can assist managers in many different ways.2) This program was established to improve access to medical care.3) Medical research expenditure has increased to nearly $350 million.4) Researchers have discovered that this drug has serious side effects.5) Exercise also will not eliminate medical problems related to blood pressure.6) Researchers have been investigating this problem for 15 years now.7) This issue was raised during the coroner’s inquest.8) He observed that the increase in life expectancy has led to some economic problems.9) Children under the age of 15 constitute nearly half of the country’s population.10) The study will conduct a series of experiments to test our hypothesis.Task 91) The study lacks solid evidence and therefore its conclusions are doubtful.2) The scientists are pretty fatigued after their lengthy experiment.3) The book attempts to explain the fundamental character of social life.4) The study confirms the fact that there is no research in this field.5) We noted a potential problem with the experimental design.6) The issue always generates a great deal of debate among academics.7) The group’s principal concern is to protect human rights.8) The research underlines the importance of an international trade agreement.9) There was an apparent discrepancy between the two sets of results.10) The primary cause of the failure was a sudden temperature change.VI.
