第31题：
Birds that are literally halfasleep--with one brain hemisphere 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 flocks led researchers to predict extra alertness in the more vulnerable, endoftherow sleepers. Sure enough, the end birdstended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.
Also, birds dozing(打盹) 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 acompanion and the other eye stayed open.
Useful as halfsleeping might be, it's only been found in birds and such water mammals(哺乳动物) 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(冰山)" 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 ________ .
A) halfbrain sleep is found in a wide variety of birds
B) halfbrain sleep is characterized by slow brain waves
C) birds can control their halfbrain sleep consciously
D) birds seldom sleep with the whole of their brain at rest 
2. 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 
3. The example of a bird sleeping in front of a mirror indicates that ________.
A) the phenomenon of birds dozing in pairs is widespread
B) birds prefer to sleep in pairs for the sake of security
C) even an imagined companion gives the bird a sense of security
D) a single pet bird enjoys seeing its own reflection in the mirror 
4. While sleeping, some water mammals 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 
5. By "just the tip of the iceberg"( Line 2, Para. 8), 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

第32题：
A nine year old schoolgirl singlehandedly cooks up a sciencefair experiment that ends up debunking(揭穿……的真相) a widely practiced medical treatment. Emily Rosa's target was a practice known as therapeutic(治疗的) touch (TT for short), whose advocates manipulate patients' "energy field"to make them feel better and even, say some, to cure them of various ills. Yet Emily's test shows that these energy fields can't be detected, even by trained TT practitioners (行医者). Obviously mindful of the publicity value of the situation, Journal editor George Lundberg appeared on TV to declare, "Age doesn't matter. It's good science that matters, and this is good science."
Emily's mother Linda Rosa, a registered nurse, has been campaigning against TT for nearly a decade. Linda first thought about TT in the late '80s, when she learned it was on the approved list for continuing nursing education in Colorado. Its 100,000 trained practitioners (48,000 in the U. S.) don't even touch their patients. Instead, they waved their hands a few inches from the patient's body, pushing energy fields around until they' re in "balance." TT advocates say these manipulations can help heal wounds, relieve Pain and reduce fever. The claims are taken seriously enough that TT therapists are frequently hired by leading hospitals, at up to $ 70 an hour, to smooth patients' energy, sometimes during surgery.
Yet Rosa could not find any evidence that it works. To provide such proof,TT therapists would have to sit down for independent testing--something they haven't been eager to do, even though James Randi has offered more than $1 million to anyone who can demonstrate the existence of a human energy field. (He's had one taker so far. She failed.) A skeptic might conclude that TT practitioners are afraid to lay their beliefs on the line. But who could turn down an innocentfourthgrader? Says Emily:"I think they didn't take me very seriously because I'm a kid."
The experiment was straight forward: 21 TT therapists stuck their hands, palms up, through a screen. Emily held her own hand over one of theirsleft or rightand the practitioners had to say which hand it was. When the results were recorded, they'd done no better than they would have by simply guessing. If there was an energy field, they couldn't feel it.
1. Which of the following is evidence that TT is widely practiced?
A) TT has been in existence for decades.
B) Many patients were cured by therapeutic touch.
C) TT therapists are often employed by leading hospitals.
D) More than 100,000 people are undergoing TT treatment. 
2. Very few TT practitioners responded to the $1 million offer because ________.
A) they didn't take the offer seriously
B) they didn't want to risk their career
C) they were unwilling to reveal their secret
D) they thought it was not in line with their practice 
3. The purpose of Emily Rosa's experiment was ________.
A) to see why TT could work the way it did
B) to find out how TT cured patients' illnesses
C) to test whether she could sense the human energy field
D) to test whether a human energy field really existed 
4. Why did some TT practitioners agree to be the subjects of Emil's experiment?
A) It involved nothing more than mere guessing.
B) They thought it was going to be a lot of fun.
C) It was more straightforward than other experiments.
D) They sensed no harm in a little girl's experiment. 
5. What can we learn from the passage?
A) Some widely accepted beliefs can be deceiving.
B) Solid evidence weighs more than pure theories.
C) Little children can be as clever as trained TT practitioners.
D) The principle of TT is too profound to understand.

第33题：
What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a specialpurpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manual driven cars. A specialpurpose lane system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway（高速公路）capacity.
Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system way was in place, automated driving could begin whenever the driver was on suitably equipped roads. If specialpurpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp(入口引道).
As the driver approached the point of entry for the highway, devices install
ed on the roadside would electronically check the vehicle to determine its destinati
on and to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to auto mated control would take place on the
