Unit 2 Cloning 一、閱讀理解。 Sometimes, you just cant help it. Maybe youre watching a sad movie, or thinking about the friend who moved away. Next thing you know, theres 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, therere 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, therere 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(延長的) childhood,” he says. “Thats the time when were 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, its 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 tears B.reflex tears C.happy tears D.emotional tears 2.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 language B.predators C.tears D.loud crying 4.What is the best title of the text? A.Types of Tears B.Precious Tears C.Secrets of Tears D.On Tears 參考答案： 1.D; 2.B; 3.C; 4.C 解析： 1.[推理判斷題。根據(jù)第二段Finally, therere emotional tears. “These are released in response to emotional states,” explains Vingerhoets.可推斷出,第一段提到的淚水屬于emotional tears。] 2.[態(tài)度判斷題。根據(jù)倒數(shù)第二段可知其實文中這兩位科學(xué)都認為淚水有好處,即積極看待眼淚。] 3.[詞義猜測題。根據(jù)文中劃線前Tears were a safer way to get attention.的敘述可知,在這種情況下(在史前時期人類大聲哭泣會引來危險的動物),最好用這種“無聲的信號”來尋求幫助。因此這種無聲的信號就是前面所指的“眼淚”。] 4.[標題歸納題。文章從科學(xué)研究的角度對眼淚的種類、哭的原因等做了科學(xué)的分析,揭示了眼淚不為人知的秘密。故該項用作文章的標題最佳。] 二、單句語法填空 1．His efforts to raise money for his program were ___________ vain because no one showed any intention to take a cent out of their pockets. 答案：in 2．The new clothes in that shop are so beautiful that Anna cannot resist___________ (take) a close look at them, although she cannot afford them at present. 答案：taking 3．The students are forbidden, unless they have special passes, ___________ (stay) out after 11 p．m. 答案：to stay 4．This is only an ___________ (assume) that they won’t spend too much on the decoration of the house. 答案：assumption 5．Liu Lei insisted that he merely did what everybody would have done and strongly objected to___________ (call) a hero. 答案：being called 6．Not having prepared well, you are bound ___________ (suffer) great losses in the mercial trade. 答案：to suffer 7．The project ___________ (undertake) by the young engineer on his own turned out to be very successful. 答案：undertaken 8．Why bother ___________ (go) abroad to study, when there are so many good universities at home? 答案：going/to go 9．I wasn’t blaming anyone; I ___________ (mere) said errors like this could be avoided. 答案：merely 10．(2018四川自貢一診)Greatly ___________ (strike) by the beauty of the language, I thought how even today Shakespeare’s writing remains powerful and true. 答案：struck 三、完形填空。 My parents owned a 500-acre farm in Montana when I was young.
