9、cted. BIts beautiful.CIts humorous. DIts discouraging.答案与解析语篇导读:本文是一篇记叙文,主要介绍了作者救助一只小猫头鹰,给它做新的窝,帮助它回到父母身边的故事。1A推理判断题。根据第一段中的“Trying to help injured, displaced or sick creatures can be heartbreaking;survival is never certain.”可知救助受伤的、流离失所的、生病的动物是令人心碎的,因为我们救助的动物是否能活下去,也就是说我们为救助动物而花费的努力可能会白费,这是不可避免的。故选

10、A。2C推理判断题。根据第二段中的“She had found a young owl (猫头鹰) on the ground. When I arrived, I saw a 2to 3weekold owl”可知有人给作者打电话是因为有只小猫头鹰掉在地上了,作者赶过去看,文中并没有说小猫头鹰受伤了,作者只是过去看情况,所以D选项错误。故选C。3A细节理解题。根据第四段中的“I placed the chick in the nest, and it quickly calmed down”可知在作者把猫头鹰放在窝里之后,它很快就安静下来,所以是窝让小猫头鹰安静下来的。故选A。4B观点态度题

11、。根据前文描述可知作者为小猫头鹰做了窝,并且帮助它找回了它的父母,小猫头鹰父母还为它带回了午餐,作者的救助成功了,说明结局是美好的。再结合第一段的“However,when it works, it is simply beautiful.”可推测,作者感觉很美好,故选B。 B When a leafy plant is under attack, it doesnt sit quietly.

13、t all kinds of plants give out VOCs when being attacked .Its a plants way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract di

The attacker who was lunching now becomes lunch.In study after study, it appears that these chemical conversations help the neighbors.The damage is usually more serious on the first plant, but the neig

15、hbors, relatively speaking, stay safer because they heard the alarm and knew what to do.Does this mean that plants talk to each other? Scientists dont know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps t

16、he neighbors just happened to “overhear” the cry. So information was exchanged, but it wasnt a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. Theres a whole lot

19、is changing faster than ever.BPeople have stronger senses than before.CThe world is more complex than it seems.DPeople in Darwins time were imaginative.答案与解析语篇导读:本文是一篇说明文。研究发现,当多叶植物受到攻击时,它们不会坐以待毙,会发出VOCs,以此来保护自己或者与周围的植物通过化学物质进行交流。5D细节理解题。根据“reported that young maple trees getting bitten by insects s

20、end out a particular smell that neighboring plants can get.These chemicals come from the injured parts of the plant and seem to be an alarm”可知,当植物受到伤害时,会分泌一种特殊的化学物质。故选D。6A词义推测题。根据“Once they arrive,the tables are turned.The attacker who was lunching now becomes lunch”,一旦它们到达这里然后这些攻击者就会成为植物的午餐,根据语境,故选

21、A。7B细节理解题。根据“ In study after study, it appears that these chemical conversations help the neighbors.The damage is usually more serious on the first plant, but the neighbors,relatively speaking,stay safer because they heard the alarm and knew what to do”可知,植物在必要的时候会通过分泌化学物质,通知周围的植物保持警惕。故选B。8C推理判断题。根据

22、“imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear.Our senses are weak.Theres a whole lot going on”可知,这个世界远比我们看到或听到的更热闹、更亲密,我们认知能力有限,有很多事仍在继续发生,远比我们想象的要复杂。故选C。COn her first morning in America last summer, my daughter went out to explore her new neighborho

23、od alone, without even telling my wife or me. Of course we were worried; we had just moved from Berlin, and she was just 8. But when she came home, we realized we had no reason to panic.

24、th a few local dog owners. When this story comes up in conversations with American friends, we usually meet with polite disbelief.

25、ids spend 90 percent of their free time at home, often in front of the TV or playing video games. Such narrowing of childrens world has happened across the developed world. But German parents are generally much more accepting of letting children take some risks. “We are depriving(剥夺) them of opportu

27、psychologist like Professor Gray, but I know I wont be around forever to protect my girls from the challenges life holds in store for them.

30、more freedom is beneficial to their mental development12Which of the following words can best describe the authors parenting?AOpenminded. BIrresponsible.CCareless.

31、 usually meet with polite disbelief.”可知,当作者和美国朋友聊到孩子独自去认识新邻居时,他们通常感到难以置信。故选C。10B推理判断题。第三段段落大意:一项加利福尼亚的研究表明,美国孩子利用90%的闲暇时间,在家看电视或打游戏。这种压缩孩子世界的现象出现在发达国家。但是德国家长大体上更能接受让孩子们去冒险。根据段意可知,德国家长没有美国家长保护欲强。故选B。11D推理判断题。根据第四段“We are depriving(剥夺) them of opportunities to learn how to take control of their own li

32、ves”和“this increases the chance that they will suffer from anxiety, depression, and various other mental disorders, which have gone up dramatically in recent decades”可知,家长们剥夺了孩子去学习如何掌控自己人生的机会。这样会使孩子们在接下来的十年成长过程中增加了焦虑,沮丧和各种其他的心理问题的几率。格雷教授的话暗示了,要给孩子们更多的自由,有利于他们的心理发展。故选D。12A推理判断题。根据文章最后一段“I wont be around forever to protect my girls from the challenges life holds in store for them.And by giving kids more control over their lives, they learn to have more confidence in their own abilities.”可知作者育儿观是开明的。故选A。
