第一节（共15白头吟卓文君小题；每小题2.5分，满分37.5分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
A
There are as many different types of sleeper as there are animal varieties on the planet. There are dozers, dreamers, nappers and hardcore dead-to-the-worlders.
Dolphins
Dolphins face a bit of a problem as they spend their whole lives in the water, but as mammals they need to breathe oxygen to survive. How do they juggle this when unconscious? Dolphins shut down half of their brain, which rests, while the other half is alert and looking out for any potential dangers. As they do this, the dolphin will lie on the surface of the water in a behaviour known as “logging”.
Elephants
Elephants tend to nod off for a few minutes at a time throughout the day. Elephants only
manage about two hours of sleep per day, and that’s not even a concentrated block of shuteye. They tend to nod off for a few minutes at a time throughout the day. Possibly becau of this, most of their sleeping is done standing up, with just the occasional recumbent sleep.
Spiders
Of cour spiders have to be awkward. Even though animals sleep in a vast array of different ways, all of them, even bacteria, follow a 24 hour cycle, known as a circadian rhythm that is dictated by the rotation of the Earth. But scientists have discovered that certain types of orb-weaving spiders simply don’t bother with this. Their body clocks follow a 17, 18 or 19 hour cycle. Scientists aren’t exactly sure how the spider can even exist with this completely different body clock.
Koalas
One problem with trying to work out a creature’s sleeping habits is the difficulty of identifyi
ng what is actual sleep. It’s easier to study captive animals, but they can behave in a completely different manner to their cousins in the wild. Koalas studied in zoos were thought to sleep for up to 22 hours a day, but a more detailed study, looking at animals in the wild too, revealed that they in fact sleep for around 14 hours a day plus a healthy amount of resting on top of that. Their diet of eucalyptus leaves takes a lot of time and energy to digest.
Frogs
Frogs are incredible. They have managed to master practically every environment on the planet, no matter how hot or how cold. They not only u hibernation in winter as a sleep strategy, they also engage in something called estivation, where they reach a dormant state during the summer months to avoid overly hot or dry conditions. Despite all this knowledge, scientists aren’t sure exactly how frogs sleep during the months when they are active.
1. Which animal sleeps the longest hours a day according to the passage?
A. The dolphin B. The koala. C. The spider. D. The elephant.
2. What is still confusing to scientists?
A. How they can identify what is actual sleep.
B. How dolphins breathe oxygen when sleeping.
C. How spiders can survive a different body clock.
D. How frogs sleep when they are not hibernating or estivating.
energ

【1题详解】
细节理解题。根据第三段中“Elephants tend to nod off for a few minutes at a time throughout the day. Elephants only manage about two hours of sleep per day, and that’s not even a concentrated block of shuteye.(大象一天中每次都会打盹几分钟。长沙会战简介>九月旅游 大象每天只能睡大约两个小时，而且这还不是集中的睡眠时间)”；第四段中“Their body clocks follow a 17, 18 or 19 hour cycle. (他们的生物钟以17、18或19个小时为一个周期)”以及倒数第二段中“Koalas studied in zoos were thought to sleep for up to 22 hours a day, but a more detailed study, looking at animals in the wild too, revealed that they in fact sleep for around 14 hours a day plus a healthy amount of resting on top of that.(动物园里被研究的考拉被认为一天睡多达22个小时，但一项更详细的研究也发现，在野外的动物中，考拉实际上一天睡大约14个小时，除此之外还有健康的休息时间)”可知，考拉每天睡的时间最长。
故选B郊区英文。

细节理解题。根据最后一段中“They not only u hibernation in winter as a sleep strategy, they also engage in something called estivation, where they reach a dormant state during the summer months to avoid overly hot or dry conditions. Despite all this knowledge, scientists aren’t sure exactly how frogs sleep during the months when they are active.(它们不仅在冬天冬眠作为一种睡眠策略，它们还会进行所谓的夏眠，即在夏季达到休眠状态，以避免过度炎热或干燥的环境。尽管知道这些，科学家们并不确定青蛙在它们活跃的那几个月里是如何睡觉的)”可知，科学家们仍然困惑的是青蛙在冬眠或夏眠时是如何睡觉的。故选梦到妈妈死了D。
【3题详解】
主旨大意题。根据第一段“There are as many different types of sleeper as there are animal varieties on the planet. There are dozers, dreamers, nappers and hardcore dead-t
o-the-worlders. (地球上有多少种动物，就有多少种不同类型的睡眠者。有打瞌睡的，有做梦的，有打盹的，还有睡到天荒地老的)”结合文章主要介绍了海豚、大象、蜘蛛、考拉和青蛙这五种动物特别的睡眠方式。可知，这篇文章的主要内容是动物睡眠的不同寻常的方式。故选C。
