10、 fill in the missing information.You can either use the exact words you have just heard or write down the main points in your own words.Finally,when the passage is read for the third time,you should check what you have written.The human body is a remarkable food processor.As an adult,you may consume

11、(S1)_ a ton of food per year and still not gain or lose a pound of body weight.You are(S2)_ harnessing,and consuming energy through the intricate(S3)_ of your body in order to remain in energy balance.To(S4)_ a given body weight,your energy input must balance your energy output.However,sometimes the

12、(S5)_ energy balance is upset,and your(S6)_ body weight will either fall or(S7)_.The term body image refers to the mental image we have of our own physical appearance,and(S8)_.Research has revealed that about 40 percent of adult men and 55 percent of adult women are dissatisfied with their current b

13、ody weight.(S9)_.At the college level,a study found that 85 percent of both male and female first year students desired to change their body weight.(S10)_.Thinness is currently an attribute that females desire highly.Males generally desire muscularity.The vast majority of individuals who want to cha

14、nge their body weight do it for the sake of appearance:most want to lose excess body fat,while a smaller percentage of individuals actually want to gain weight.Part II Reading Comprehension(35 minutes)Directions:There are 4 reading passages in this part.Each passage is followed by some questions or

15、unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Passage One Questions 11 to 15 are based on the following passage.Birds that are litera

16、lly half asleepwith one brain hemisphere alert and the other sleepingcontrol 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 charac

17、terized by slow brain waves.The eye controlled by the sleeping hemisphere keeps shut,while the wakeful hemispheres 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,e

18、nd 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(打盹)at the end of the line resorted to single hemisphere sleep,rather than total relaxation,more often t

19、han 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 a

20、nd 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,h

21、e 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,its only been found in birds and such water mammals(

22、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(

23、冰山)”He speculates that more examples may turn up when we take a closer look at other species.11.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 con

24、sciously D)birds seldom sleep with the whole of their brain at rest 12.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 consta

25、ntly keep an eye on their companions 13.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 pe

26、t bird enjoys seeing its own reflection in the mirror 14.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 c

27、urrents 15.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 D)half brain sleep is a phenomenon that cou

28、ld exist among other species Passage Two Questions 16 to 20 are based on the following passage.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 Rosas target was a practice known as therapeutic(治疗的)to

29、uch(TT for short),whose advocates manipulate patients“energy fieldto make them feel better and even,say some,to cure them of various ills.Yet Emilys test shows that these energy fields cant be detected,even by trained TT practitioners(行医者).Obviously mindful of the publicity value of the situation,Jo

30、urnal editor George Lundberg appeared on TV to declare,“Age doesnt matter.Its good science that matters,and this is good science.”Emilys 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 th

31、e approved list for continuing nursing education in Colorado.Its 100,000 trained practitioners(48,000 in the U.S.)dont even touch their patients.Instead,they waved their hands a few inches from the patients body,pushing energy fields around until theyre in“balance.”TT advocates say these manipulatio

32、ns 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

33、therapists would have to sit down for independent testingsomething they havent 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.(Hes had one taker so far.She failed.)A skeptic might conclude that TT practitio

34、ners are afraid to lay their beliefs on the line.But who could turn down an innocent fourth grader?Says Emily:“I think they didnt take me very seriously because Im 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

35、 of theirs left or right and the practitioners had to say which hand it was.When the results were recorded,theyd done no better than they would have by simply guessing.If there was an energy field,they couldnt feel it.16.Which of the following is evidence that TT is widely practiced?A)TT has been in

36、 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.17.Very few TT practitioners responded to the$1 million offer because _.A)they didnt take the offer seriously B)they d

37、idnt want to risk their career C)they were unwilling to reveal their secret D)they thought it was not in line with their practice 18.The purpose of Emily Rosas 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 t

38、he human energy field D)to test whether a human energy field really existed 19.Why did some TT practitioners agree to be the subjects of Emils 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.

39、D)They sensed no harm in a little girls experiment.20.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.

40、Passage Three Questions 21 to 25 are based on the following passage.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 re

41、served 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

42、 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

43、 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 installed on the roadsi

44、de would electronically check the vehicle to determine its destination 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

45、to auto mated control would take place on the entrance ramp.An alternative technique could employ conventional lanes,which would be shared by automated and regular vehicles.The driver would steer onto the highway and move in normal fashion to a“transition”lane.The vehicle would then shift under comp

46、uter control onto a lane reserved for automated traffic.(The limitation of these lanes to automated traffic would,presumably,be well respected,because all trespassers(非法进入者)could be swiftly identified by authorities.)Either approach to joining a lane of automated traffic would harmonize the movement

47、 of newly entering vehicles with those already traveling.Automatic control here should allow for smooth merging without the usual uncertainties and potential for accidents.And once a vehicle had settled into automated travel,the driver would be free to release the wheel,open the morning paper or jus

48、t relax.21.We learn from the first paragraph that two systems of automated highways _.A)are being planned B)are being modified C)are now in wide use D)are under construction 22.A special purpose lane system is probably advantageous in that _.A)it would require only minor changes to existing highways

49、 B)it would achieve the greatest highway traffic efficiency C)it has a lane for both automated and partially automated vehicles D)it offers more lanes for automated vehicles 23.Which of the following is true about driving on an automated highway?A)Vehicles traveling on it are assigned different lane

50、s according to their destinations.B)A car can join existing traffic any time in a mixed lane system.C)The driver should inform his car computer of his destination before driving onto it.D)The driver should share the automated lane with those of regular vehicles.24.We know from the passage that a car
