Unit 2 Cloning一、阅读理解。

Sometimes, you just can't help it. Maybe you're watching a sad movie, or thinking about the friend who moved away. Next thing you know, there's a lump in your throat, your eyes are watering, and you have tears running down your cheeks.A professor of psychology at Tilburg University, in the Netherlands,has studied crying.According to Vingerhoets, there're three types of tears. Basal tears are the first type. They act as a protective barrier between the eye and the rest of the world.Next are reflex tears. They wash your eyes clean when something gets in them. Finally, there're emotional tears. “These are released in response to emotional states,” explains Vingerhoets.Scientists believe crying has something to do with how humans developed and learned to depend on each other. “Humans are very plex social creatures,” says Lauren Bylsma, a professor from Pittsburgh University, in Pennsylvania. “It seems that tears can make them get help and support from others.”She says another reason why we weep is that humans have the longest developmental period of almost any animal. It takes a long time to grow up.Vingerhoets agrees. “I think that the reason why humans shed(流出)emotional tears has to do with our prolonged(延长的) childhood,” he says. “That's the time when we're still dependent on adults for love,protection and care. The major advantage of tears is that you can target them at a specific person.”Vingerhoets says this ability could have e in handy in prehistoric times, when humans were living among dangerous animals. Loud crying could attract predators(捕食者). Tears were a safer way to get attention. “In this case, it's better to use a silent signal to ask for help,” he says. Vingerhoets and Bylsma do frequent studies to better understand why humans cry.1.The tears mentioned in Paragraph 1 should belong to ________.A.basal tearsB.reflex tearsC.happy tearsD.emotional tears2.What is Vingerhoets' attitude to the effects of tears?A.Passive.B.Positive.C.Doubtful.D.Indifferent.3.The underlined phrase of “a silent signal” probably refers to ________.A.a written languageB.predatorsC.tearsD.loud crying4.What is the best title of the text?A.Types of TearsB.Precious TearsC.Secrets of TearsD.On Tears参考答案： 1.D; 2.B; 3.C; 4.C解析： 1.[推理判断题。

“Cleverness is a gift while kindness is a choice. Gifts are easy—they’re given after all. Choices can be hard. ”—Jeff Bezos.I got the idea to start Amazon in 1995. I came across the fact that the Internet usage was growing at 2, 300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always want ed to be an inventor, and she wanted me to follow my passion.I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job. ” That logic mad e some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it was really a difficult choice, but ultimately, I decided I had to give it a shot. I didn’t think I’d regret trying and failing. An d I suspected I would always be haunted by a decision to not try at all.After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.【文章大意】本文讲述了亚马逊网站的创始人的成长故事。

Text 1M：Have you tried the fish? It is very tasty.W：As a matter of fact, I don't care for seafood.M：Really? What about the green vegetables?W：I like anything but seafood.Text 2M：I'm going to drop my information science class. I need to get up too early in the morning.W：Is that really the good reason to drop the class, Tony?Text 3M：Animals, including insects, do not have a language like ours. They do not talk to each other in words or sentences. But if we watch them, we can see that they do have ways of communicating.Can you see the rabbits' tail? When rabbits see this white tail moving up and down, they are warning each other to run. They know that there is danger. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is. Some animals say things by making sound. A dog barks, for example when a stranger comes near. A cat purrs when pleased. Some birds make several different sounds, each with its own meaning.Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah！” when we are frightened or pleased or when we dr op something on our toes. Of things, actions, feelings or ideas, we are able to give each other all kinds of different expressing. But we have something that no animals have—a large number of words which have the meanings, information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have.1．核心单词(1)differ (vi.) 不同；相异→difference (n.) 不同；差异→different (adj.) 不同的(2)cast (vt.) 扔；投；掷→cast (过去式/过去分词)(3)object (vi.) 反对；不赞成→objection (n.) 反对；不赞成；异议(4)obtain (vt.) 获得；赢得→obtainable (adj.) 可获得的；可得到的(5)owe (vt.) 欠(账、钱、人情等)；归功于……→owing (adj.) 欠着的；未付的(6)retire (vi.) 退休；离开→retirement (n.) 退休；退职→retired (adj.) 退休的(7)bother (vt.) 打扰 (vi.) 操心 (n.) 烦扰(8)strike (vt.& vi.) 打；撞击；罢工(n.) 罢工→struck (过去式/过去分词)(9)vain (adj.) 虚荣的；自负的；徒劳的(10)resist (vt.) 抵抗；对抗→resistance (n.) 抵抗力；反抗→resistant (adj.) 有抵抗力的2．阅读单词(1)exact (adj.) 精确的；准确的(2)commercial (adj.) 商业的；贸易的(3)undertake (vt.) 着手；从事；承担(4)breakthrough (n.) 突破(5)procedure (n.) 程序；步骤；手续(6)forbid (vt.) 禁止；不准(7)accumulate (vt.& vi.) 积累；聚积(8)assumption (n.) 假定；假想；设想(9)regulation (n.) 规则；规章；法规(10)reasonable (adj.) 合情理的；讲道理的；公道的【即景活用】用括号内所给单词的适当形式填空1．His explanation was not ________(reason), so all of us didn't accept it.答案：reasonable2．From the appearance, we can not tell the ________(differ) between the twins.答案：difference3．After his _______ (retire), he settled down in a remote village.答案：retirement4．Grey decided to move to the countryside and his mother made no ________ (object) to it.答案：objection5．What I want is ________ (exact) this one.答案：exactly6．We can't ________ (undertake) the work for the time being.答案：undertake7．It is difficult ________(obtain) reliable evidence.答案：to obtain8．We are playing a trick on a man who keeps ________(bother) me.答案：bothering9．His own pride ________(forbid) him to ask Tom's help.答案：forbids10．Will they be able ________(resist) the temptation to buy?答案：to resist联想积累1．快速掌握“获得”家族①receive收到，得到(信、命令、请帖等)；接受(欢迎，请愿等)②get获得；赚得；赢得③obtain得到，获得；达到(目的)④acquire获得；招致；学得；养成(习惯等)⑤gain获得；赢得，打胜(战争、官司)⑥be available可以得到的，可以买到的2．巧记合成词①fall down→downfall 垮台②get together→get­together 聚会③break through→breakthrough 突破④break out→outbreak 爆发1．all_the_time 一直；始终2．pay_off 得到好结果；取得成功；偿清3．cast_down 使失望；使沮丧4．in_favour_of 赞成；支持5．(be) bound to (do) ... 一定或注定(做)……6．strike ... into one's heart 使……刻骨铭心7．from time to time 不时；偶尔8．bring back to life 使复生；使复活9．in vain 白费力气；枉费心机10．in good/poor condition 状况很好/坏；情况很好/坏【即景活用】用所给短语的适当形式填空1．The house is really ________and it would cost too much to repair.答案：in poor condition2．She has succeeded.

Unit 2 Cloning阅读理解组块专练——练速度(限时：35分钟)Ⅰ.阅读理解AWe are all fascinated by mysteries. To some extent we love to expect strange phenomenon occurring before us. Here are some amazing unsolved mysteries.The Georgia GuidestonesOn one of the highest hilltops in Elbert County, Georgia stands a giant granite monument (花岗岩纪念碑). Carved in eight different languages on the four giant stones are 10 Guides.The origin of this strange monument is covered in mystery because no one knows the true identity of the man, or men, who constructed it. All we know is that in June 1979, a man identifying himself as R．C.Christian announced that he would build something to convey a message to mankind, but to date, no one knows who R．C.Christian really was.Bermuda TriangleThe Bermuda Triangle is a triangular area of the Atlantic Ocean. Many planes, ships, and boats are said to have disappeared in this triangle without a trace, which led to the belief that “supernatural” forces exist in this area of the sea.Could there truly be an unnatural force at work in this geographical triangle or are these disappearances merely coincidence? Either way, numerous people remain unwilling to step over the boundary line into the Devil’s Triangle.Loch Ness MonsterThe Loch Ness Monster is a legendary animal that supposedly lives in the depths of Loch Ness, a long narrow lake located in rural Scotland.Stories concerning the monster date back to the 6th century AD. Over the years thousands have reported seeing a long neck appearing from the water with a small head of an unknown creature. Pictures have even been taken of this “creature”，but most scientists refuse to believe any creature of this kind lives in the Loch Ness. So far, the evidence is inadequate, and the controversy continues.A．It is on one of the highest hilltops in Elbert County.B．There are eight different languages on the stones.C．The person who built it remains unknown.D．R. C. Christian could convey a message to mankind.解析：选C 细节理解题。
