Birds that are half-asleep—with one brain hemisphere (半球) alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.
Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled 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 groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. 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 napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half-asleep during some 32 percent of napping time.
“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say.
The results provide the best evidence for a long-standing assumption 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 napping 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 animals as dolphins, 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 supposes that more examples may turn up when we take a closer look at other species.
According to the passage, birds often half sleep because ______.
A. they have to watch out for possible attacks
B. their brain hemispheres take turns to rest
C. the two halves of their brain are differently structured
D. they have to constantly keep an eye on their companions
What is implied about the example of a bird’s sleeping in front of a mirror?
A. An imagined companion gives the bird a sense of security.
B. Birds prefer to sleep in pairs for the sake of their security.
C. The phenomenon of birds napping in pairs is widespread.
D. A single pet bird enjoys seeing its own reflection in the mirror.
While sleeping, some water animals tend to keep half awake in order to ______.
A. alert themselves to the approaching enemy
B. emerge from water now and then to breathe
C. be sensitive to the ever-changing environment
D. avoid being swept away by rapid currents
By saying “just the tip of the iceberg”, Siegel suggests that ______.
A. half-brain sleep has something to do with icy weather
B. the mystery of half-brain sleep is close to being solved
C. most birds living in cold regions tend to be half sleepers
D. half-brain sleep may exist among other species

Zoos divide opinion : there are those who think it is cruel to keep animals locked up while others believe zoos are essential for the survival of endangered species.
To argue that zoos imprison animals is to misunderstand what zoos are about. Without zoos many of the creatures we love and admire would no longer exist. Every single day,over one hundred animal species vanish. Scientists predict that as early as 2050 one quarter of the Earth’s species will become extinct.
Some animals are in danger because they are hunted. Alarmingly, the population of tigers has already fallen by ninety-five percent. Other species are in danger because of a lack of food. For example, there are fewer than 1300 giant pandas left in the wild.
Zoos have special breeding programmes to help those animals at risk. These breeding programmes are proving extremely successful. As Irene Shapiro from Zoo and Wildlife Support says, “the Puerto Rican Parrot has grown in numbers from just thirteen to about eighty-five and the Golden Lion Tamarin Monkey, which has almost ceased to exist twenty years ago, has been reintroduced back into the wild. ”
Unfortunately, not everyone understands this important role zoos play. For example, Brian Featherstone from the Anti-Zoo Forum says, “I can’t believe we take animals from the wild and put them in cages for the entertainment of the public! We should view them on film or TV in their natural environment.,’
However, this misses the point. A zoo does more than display animals to the public. It ensures their survival. Without zoos you would not be able to see many of these animals on TV or anywhere else!
1.What’s the writer’s attitude towards zoos?
A.He shows no opinion either for or against them.
B.He thinks that they are unnecessary and cruel.
C.He believes they play an important environmental role.
D.He expresses a desire that more of them be built.
2.The underlined word “vanish” in Paragraph 2 most probably means _____.
A.remain B.disappear C.become rarer D.get killed
3.According to the passage the world’s tiger population _____.
A.will rise by 5% next year B.is relatively stable
C.is 95% smaller than in the past D.has fallen to 95%
4.According to the passage some people do not agree with zoos because they _____
A.a(chǎn)re too expensive to run B.put animals in danger
C.do not provide enough food D.keep animals locked up
5.According to the writer ,the most important function of the zoo is to _____.
A.make a lot of money B.entertain visitors
C.ensure animals’ survival D.educate the public

第三部分:閱讀理解 (共20小題,每題2分,滿分40分)
第一節(jié):(共15小題,滿分30分)
Police in the Russian city of St. Petersburg were today searching for a rare missing leopard which was stolen yesterday when thieves attacked a TV producer and drove off in his luxury Mercedes 4×4.
The amur leopard, which was in the boot, is one of the world’s most highly endangered species, with fewer than 45 left in the wild in Russia’s remote far east. About 300 others are captive in zoos around the world.
According to its owner, Mikhail Barakin, the thieves were wearing masks. They attacked him and his driver, throwing both of them out of the vehicle, shortly after they drove to St. Petersburg with leopard from Moscow.
“She’s a female leopard cub and she’s incredibly tame,” Barakin told the Guardian this morning. “She’s just over a month old. The leopard was brought up in captivity.”
He went on, “We had been driving all night with the leopard in a travel cage. The plan was to take her to the vet. My driver and I were in the process of setting the leopard in the trunk of my Mercedes…when three masked assailants attacked us. They managed to get away with the car. My suspicion is the theft was done to order.”
Barakin said the leopard, a present from a Moscow businessman, was far more valuable than the stolen Mercedes. He has offered a £85,400 reward for its safe return, and says he is prepared to drop all charges if the thieves bring the animal back.
The leopard was to have been housed in a purpose-built enclosure on a country estate outside St. Petersburg, he added. Barakin said he had hired a specialist to look after it, and was planning to use the cub in TV commercials.
36. We can infer from the passage that the three assailants ______.
A. probably came for the leopard B. would return the leopard safely
C. didn’t know there was a leopard in the car D. were known to Mikhail Barakin
37. The leopard was believed to be more valuable because ______.
A. it was already tamed B. it could be kept as a pet
C. it would be used in TV commercials D. it was an endangered species
38. Mikhail Barakin drove the leopard to ______.
A. put her in a bigger place B. use it in TV commercials
C. put her in better care D. keep her in the zoo
39. If the thieves brought the leopard back, Mikhail Barakin would ______.
A. send them to prison B. give them a reward
C. give them the car as a reward D. not charge them
40. The underlined word “boot” in Paragraph 2 probably refers to ______.
A. a special cage B. a type of shoe
C. the trunk of a car D. a kind of camera
