After several attempts at keeping my eyelids from fluttering closed and the book from collapsing on to my chest, I know it really is time to go to sleep. I affectionately place the book on the bed beside me. We sleep together, me and my book, me and those characters, me and my mixed-up dreams. Reading in bed seems to run in families. The last time my mother babysat for me, got home to find the house dark except for two small lights. One came from my son’s room, where I discovered the eight-year-old holed up under the covers with Goosebumps and a flashlight. At the other end of the house, my mother had already dozed off with her book.2. 单选题Researchers produced evidence to support what most of us already knew—that a cup of tea is the answer to any crisis.Dr. Malcolm Cross, a psychologist at City University London, tested the anxiety levels of a group of people following a （1）   situation and revealed that even a single cup of tea has a （2）   calming effect.

Sir Humphrey Gilbert was the first Englishman to send colonists to the New World. His initial expedition, which sailed in 1578 with a patent granted by Queen Elizabeth was defeated by the Spanish. A second attempt ended in disaster in 1583, when Gilbert and his ship were lost in a storm. In the following year, Gilbert’s half brother, Sir Water Raleigh, having obtained a renewal of the patent, sponsored an expedition that explored the coast of the region that he named “Virginia”. Under Raleigh’s direction efforts were then made to establish a colony on Roanoke Island in 1585 and 1587.The survivors of the first settlement on Roanoke returned to England in 1586, but the second group of colonists disappeared without leaving a trace. The failure of the Gilbert and Raleigh ventures made it clear that the tasks they had undertaken were too big for any one colonizer. Within a short time the trading company had supplanted the individual promoter of colonization.1. Which of the following would be the most appropriate title for the passage?2.

The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eyeControlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.Decades of studies of bird flocks led researchers to predict extra alertness in the more vulnerable, end-of-the-row sleepers. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.Also, birds dozing at the end of the line resorted to single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Rotating 16 birds through the positions in a four duck row, the researchers found outer birds half-asleep during some 32 percent of dozing time versus about 12 percent for birds in internal spots.“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness simultaneously in different regions of the brain,” the researchers say.The results provide the best evidence for a long-standing supposition that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds dozing side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.Useful as half-sleeping might be, it’s only been found in birds and such water mammals asDolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg”. He speculates that more examples may turn up when we take a closer look at other species.1. A new study on birds’ sleep has revealed that ____________.2. According to the passage, birds often half sleep because ____________.3. The example of a bird sleeping in front of a mirror indicates that ____________.4. While sleeping, some water mammals tend to keep half-awake in order to ____________.5. By “just the tip of the iceberg” (Line 2, Para. 8), Siegel suggests that ____________.问题1选项A.half-brain sleep is found in a wide variety of birds,B.half-brain sleep is characterized by slow brain wavesC.birds can control their half-brain sleep consciouslyD.birds seldom sleep with the whole of their brain at rest问题2选项A.they have to watch out for possible attacksB.their brain hemispheres take turns to restC.the two halves of their brain are differently structuredD.they have to constantly keep an eye on their companions问题3选项A.the phenomenon of birds dozing in pairs is widespreadB.birds prefer to sleep in pairs for the sake of securityC.even an imagined companion gives the bird a sense of securityD.a single pet bird enjoys seeing its own reflection in the mirror问题4选项A.alert themselves to the approaching enemyB.emerge from water now and then to breatheC.be sensitive to the ever-changing environmentD.avoid being swept away by rapid currents问题5选项A.half-brain sleep has something to do with icy weatherB.the mystery of half-brain sleep is close to being solvedC.most birds living in cold regions tend to be half sleepersD.half-brain sleep is a phenomenon that could exist among other species.【答案】第1题:C第2题:A第3题:C第4题:D第5题:D【解析】1.语义推测题。

根据第一段第一句Birds that are literally half-asleep—with one brain hemisphere alert and the other sleep—control which side of the brain remains awake, according to a new study of sleeping ducks.（根据一项对睡着的鸭子的最新研究，鸟类处于半睡眠状态，其中一个脑半球保持警戒，另一个脑半球用来睡觉——或者控制这一侧大脑保持清醒可知鸟类可以控制自己的睡眠，所以C选项“鸟类可以有意识地控制他们的半脑睡眠”正确A选项“发现半脑睡眠出现在很多鸟类身上”，B选项“半脑睡眠的特点是脑电波缓慢”和D选项“鸟类很少在休息的时候用整个大脑睡觉”：根据第二段第一句Earlier studies have documented half-brain sleep in a wide range of birds.（早期的研究已经记录了很多鸟类的半脑睡眠可知这是早期研究的结果，故错误推测因此C选项正确2.事实细节题根据第六段第一句single-hemisphere sleep evolved as creatures scanned for enemies（动物在观察周围以提防敌人时进化出了半脑睡眠），可知动物因为要提防敌人保护自己而发展出来半脑睡眠，所以A选项“他们必须提防可能的攻击”正确。

B选项“他们的大脑半球轮流休息”：这是半脑睡眠带来的影响和好处，而非原因，故错误C选项“他们的大脑的两个半球是不同的结构”：文章没有提到鸟类的脑部结构是怎样的，故错误D选项“他们必须时刻注意他们的同伴”：这属于半脑睡眠运用的地方和体现，而非原因，故错误因此A选项正确3.推理判断题根据第六段最后一句The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.（镜子那边的那只眼睛闭上了，好像镜子里的那只眼睛是同伴，而另一只眼睛则一直睁开着可知即使没有真正的同伴在，鸟儿也会视镜子中的自己为同伴，不一定非得要和同伴一起睡觉，结合鸟类的半脑睡眠是因为保护自己，所以C选项“即使是一个想象中的同伴也会给鸟一种安全感”正确，B选项“为了安全起见，鸟儿喜欢成对睡觉”和D选项“一只宠物鸟喜欢看到自己在镜子里的倒影”错误A选项“鸟儿成对打瞌睡的现象很普遍”：没有提到，故错误因此C选项正确4.事实细节题根据第七段最后一句Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.（也许保持一侧大脑清醒可以让睡着的动物偶尔浮出水面，以避免溺水。

可知一些水生哺乳动物为了在睡着时保持安全而发展出半睡眠状态，所以D选项“避免被急流冲走”正确A选项“警惕接近的敌人”，B选项“偶尔从水里冒出来呼吸”和C选项“感知不断变化的环境”没有提到，故错误因此D选项正确5.语义推测题根据第八段最后一句He speculates that more examples may turn up when we take a closer look at other species.（他推测，当我们进一步观察其他物种时，可能会发现更多的例子可知Jerome M. Siegel认为半脑睡眠可能也存在于其他生物，所以D选项“半脑睡眠是一种可能存在于其他物种中的现象”正确A选项“半脑睡眠与寒冷天气有关”和C选项“大多数生活在寒冷地区的鸟类往往是半睡眠者”：这里的冰山一角和天气寒冷无关，故错。
