Even so, its scientists use some 12 million animals a year, most of them mice and rats, for medical research.Official statistics show that just 1.1 million animals are used in research in America each year.But that is misleading.The American authorities do not think mice and rats are worth counting and, as these are the most common laboratory animals, the true figure is much higher.Japan and China have even less comprehensive data than America.Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs.Alternatives to animal testing, such as using human tissue or computer models, are now strongly recommended.In addition, sharing all research results freely should help to reduce the number of animals for scientific use.At present, scientists often share only the results of successful experiments.If their findings do not fit the hypothesis being tested, the work never sees the light of day.This practice means wasting time, money, and animals lives in endlessly repeating the failed experiments.Animal experimentation has taught humanity a great deal and saved countless lives.It needs to continue, even if that means animals sometimes suffer.Europe s new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.16What is the main idea of this passage?AThe success of animal experiments should be ensured.BBan on the use of animals in the lab should be enforced.CGreater efforts need to be taken to reduce the number of lab animals.DScientists should be required to share their research results with each other.17Which of the following statements is true about animals used in the lab?AAmerica uses only about 1.1 million lab animals per year.BEurope does not use mice and rats as lab animals at all.CBritain does not use as many lab animals as China does.DJapan has limited data on the number of lab animals used each year.18Which of the following is mentioned as an alternative to replace animal experiments?AStatistical studies. BComputer models.CDNA planted in animals. DTissue from dead animals.19What usually happens to unsuccessful animal experiments?AThey are not revealed to the public.BThey are made into teaching materials.CThey are collected for future publication.DThey are not removed from the research topic list.BToday we will explain a very old saying that has had a big influence on rockandroll music. That saying is “A rolling stone gathers no moss”It has several meanings. One meaning is that a person who never settles down in one place will not be successful. Another is that someone who is always moving, with no roots in one place, avoids responsibilities.This proverb was said to be first used in the 1500s. But in the 1960s, the expression “rolling stone” became famous in the world of rockandroll music. It became the name of a song, a rock group and a magazine.Experts say it all started with a song by the American singer and guitarist Muddy Waters. He was one of the countrys top blues musicians until his death in 1983. His music influenced singers like Elvis Presley and Bob Dylan. In 1950, Muddy Waters recorded a song called “Rolling Stone”A British rock group is said to have taken its name from Muddy Waters song. The Rolling Stones performed for the first time in 1962.The groups members called themselves “the worlds greatest rockandroll band”In 1965, Bob Dylan released his song “Like a Rolling Stone”It is one of his best known and most influential works.It is an angry song about a woman who was once rich and successful. But now she is on her own，“with no direction home, like a complete unknown, like a rolling stone”In 1967, a young man named Jann Wenner started a magazine and he named it “Rolling Stone”The magazine reported on rock music and the popular culture that the music created. By 1971，“Rolling Stone” had become the leading rock music and counterculture publication. It is still popular today.20Which person can be described as a rolling stone according to the proverb?AA person who always changes his jobs.BA person who has a successful career.CA person who has no family.DA person who is out of work.21All of them are musicians except _AElvis Presley BBob DylanCMuddy Waters DJann Wenner22Who first used “rolling stone” as a name for music?AJann Wenner. BBob Dylan.CElvis Presley. DMuddy Waters.开放作文请根据下面提示，写一篇短文。词数不少于50。You are discussing the following picture with your English friend Jim. Now you are telling him how you understand the picture and what makes you think so._参考答案课时作业(五).1.C考查冠词的用法。in trouble 处于困境中；lose heart 失去信心。2B考查非谓语动词的用法。devote的逻辑主语就是主句的主语Principal White, 后面有宾语all his energy，所以用现在分词表主动。3B考查动词短语辨析。set up 成立，建立，符合句意。 pack up 包起来；add up 加起来； come up 出现。4B考查副词词义辨析。句意：我不能说自己是最好的，相对而言，我只是比别人付出更多努力而已。definitely意为“肯定地，当然地，明确地”；relatively意为“相对地，比较地”；obviously意为“显然地”；certainly意为“当然，一定”。根据句意可知B项正确。5C考查形容词辨析。acceptable可接受的，与to搭配，符合句意。available 可用的； considerable相当多(或大、重要等)的； practical 实际的。6D考查动词的时态和语态。根据句意可知，reward所表示的动作发生在“donated”这一动作之前，所以用过去完成时；分析句子结构可知，“reward”与“the two nurses”之间是逻辑上的动宾关系，应用被动语态。故选D。7A考查动词短语辨析。句意：她新买的电脑使用起来很困难，但她不知道向谁求助。 turn to 求助于；look for 寻找； deal with 处理； talk about 谈论。8D考查动词的时态和定语从句。句意：在过去这30年中，我们已经见证了，故用现在完成时；stage作先行词，后面的定语从句中缺少地点状语，所以用where。9B考查动词的时态。句意：已经成立一个工作小组去调查这个问题了。故用现在完成时的被动语态。10C考查动词的用法。escape后跟动名词作宾语；由于主语the little boy是burn动作的承受者，所以要用动名词的被动式。11D考查副词的用法。根据本句后半部分的内容可知这座岛屿在春天和秋天同样吸引人，所以用equally表示“相等地，同样”。12D考查固定搭配。将句子成分great trouble放回原处，即have trouble(in) doing可知答案是D。13B考查倒装结构。句意：只有在他们讨论这个问题好几个小时之后他们才作出决定。only修饰时间状语从句且位于句首时，主句应采用部分倒装的形式。根据状语从句的时态可以确定主句应用一般过去时态。故选B。14B考查名词短语的连词功能。the first time相当于一个连词，意为“第一次”。15B考查词语辨析。句意：她假装镇静但实际上在被提问时她十分紧张。 actually 实际上，相当于 in fact, as a matter of fact。.A用动物进行试验被人们的舆论推向了风口浪尖，然而，受诸多因素的影响，终止动物实验的道路依然任重而道远。尽管欧洲有严格的法律限制，但是仍然需要另找突破口。16C主旨大意题。文章第一段指出用动物进行试验难以杜绝的原因，第二段提到欧洲对动物实验的法律限制的效果并不理想，第三段讲了欧洲为限制动物实验所作出的努力，最后一段提到欧洲的新措施应该既要减少用于实验的动物的数量，又要改善科学研究的方法，所以C项最能概括文章大意。17D正误判断题。第二段的最后一句提到日本和中国与美国的数据相比甚至更不全面，由此可推知日本对每年用于实验室动物的数据记录有限。18B细节理解题。根据第三段第二句中的内容可知可用“人体组织”和“电脑模型”来取代动物实验。19A推理判断题。根据第三段中的倒数第二、第三句可知，科学家们只分享成功的试验，如果结果与假设不符，所做的工作将不公开。由此可推断不成功的试验不会展示给公众。B本文讲述的是谚语A rolling stone gathers no moss.“滚石不生苔，改行不攒财”对滚石音乐的影响以及滚石杂志的诞生。20A 推理判断题。从第一段的最后两句话可知这句谚语有两种含义，一种是那些不安心待在某个地方的人不会成功，另一种是那些扎不下来根儿的人不负责任。A项指的是经常换工作的人，符合题意。21D细节理解题。根据第三段可知Elvis Presley，Bob Dylan和Muddy Waters都是音乐家；根据最后一段可知Jann Wenner是开办杂志滚石的人。故选D。22D细节理解题。根据第三段的第一句“Experts say it all started with a song by the American singer and guitarist Muddy Waters.”可知，rolling stone作为音乐的名字最早是被Muddy Waters使用的。.Possible version 1：Jim, lets look at this picture. You see, the boy in the picture is showing off his strong right arm and proud of his great strength. However, his left arm appears rather weak. In my opinion, the picture wants to tell us that we should not overlook our weakness. Usually, we tend to take pride in our advantages just like the boy. But we really should know that the shortcomings, like the weak left arm of the boy, may prevent us from achieving success. So I think we ought to work on our weaknesses and strengths at the same time. What do you think, Jim?Possible version 2：Jim, lets look at this interesting picture. You see, the boy in the picture is happily showing off his strong right arm. It is clear that he is very proud of his great strength while he ignores his left arm, which appears so weak.In my opinion, the picture shows that we should keep a balance between our strengths and weaknesses. The boy in the picture only focuses on his strong right arm which symbolizes his strengths but ignores his thin left arm which represents his weak points. Consequently, he may encounter failure in the future. As we all know, we often spend all our time and energy strengthening our advantages. But we really need to work on the weaknesses. Otherwise, we will be dragged down by the shortcomings and never achieve success.Personally, I would not do so like the boy. What do you think, Jim?- 6 -
