Directions: There are 4 passages in this part.Each passage is followed by some questions or unfinished statements.For each of them there are four choi ces 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.
Questions 21 to 25 are based on the following passage:
Unless we spend money to spot and prevent asteroids(小行星)now，one might crash into Earth and destroy life as we know it，say some scientists.?
Asteroids are bigger versions of the meteoroids(流星)that race acros s the night sky.Most orbit the sun far from Earth and don't threaten us.But th ere are also thousads whose orbits put them on a collision course with Earth.?
Buy $ 50 million worth of new telescopes right now.Then spend $ 10 million a year for the next 25 years to locate most of the space rocks.By the time we spot a fatal one，the scientists say，we'll have a way to change its course.?
Some scientists favor pushing asteroids off course with nuclear weapons.But the cost wouldn't be cheap.?
Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs.Experts think an asteroid big enough to destroy lots of life might strike Earth once eve ry 500，000 years.Sounds pretty rare-but if one did fall，it would be the end of the world.“If we don't take care of these big asteroids，they'll take care of us，”says one scientist.“It's that simple.”?
The cure，though，might be worse than the disease.Do we really want fleets of nuclear weapons sitting around on Earth?“The world has less to fear from
doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.
21. What does the passage say about asteroids and meteoroids?
A) They are heavenly bodies different in composition.
B) They are heavenly bodies similar in nature.
C) There are more asteroids than meteoroids.
D) Asteroids are more mysterious than meteoroids.
22. What do scientists say about the collision of an asteroid with Earth?
A) It is very unlikely but the danger exists.
B) Such a collision might occur once every 25 years.
C) Collisions of smaller asteroids with Earth occur more often than expected.
D) It's still too early to say whether such a collision might occur..
23. What do people think of the suggestion of using nuclear weapons to alter the
course of asteroids?
A) It sounds practical but it may not solve the problem.
B) It may create more problems than it might solve.
C) It is a waste of money because a collision of asteroids with Earth is very
unlikely.
D) Further research should be done before it is proved applicable.
24. We can conclude from the passage that .
A) while pushing asteroids off course nuclear weapons would destroy the world
B) asteroids racing across the night sky are likely to hit Earth in the near future
C) the worry about asteroids can be left to future generations since it is unlikely
to happen in our lifetime
D) workable solutions still have to be found to prevent a collision of asteroids
with Earth.
25. Which of the following best describes the author's tone in this pass age?
A) Optimistic. B) Critical. C) Objective. D) Arbitrary.
Questions 26 to 30 are based on the following passage:
Believe it or not，optical illusion (错觉) can cut highway crashes.Japan is a case in point.It has reduced automobile crashes on some roads by nea rly 75 percent using a simple optical illusion.Bent stripes，called chevrons (人字形)painted on the roads make drivers think that they are d riving faster than they really are，and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D.C.is planning to rep eat Japan's success.Starting next year,the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a major role role in as much as one fifth of all fatal traffic accidents,according to the foundation .To help reduce those accidents，the foundation will conduct its tests in areas where speed - related hazards are the greatest - curves，exit slopes，traffic c ircles，and bridges.Some studies suggest that straight，horizontal bars painted across roads can initially cut the average speed of drivers in half.However，t raffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons，scientists say，not only give drivers the impress ion that they are driving faster than they really are but also make a lane sppea r to be narrower.The result is a longer lasting reduction in highway speed and the number of traffic accidents.
26. The passage mainly discusses .
A) a new way of highway speed control
B) a new pattern for painting highways
C) a new approach to training drivers
D) a new type of optical illusion

C) will have a longer effect on drivers
D) will look more attractive
29. The American Association Foundation for Traffic Safety plans to .
A) try out the Japanese method in certain areas
B) change the road signs across the country
C) replace straight，horizontal bars with chevrons
D) repeat the Japanese road patterns
30. What does the author say about straight，horizontal bars painted acr oss roads?

Questions 31 to 35 are based on the following passage:
Amtrak(美国铁路客运公司)was experiencing a downswing in riders hip (客运量)along the lines comprising its rail system.Of major concern t o Amtrak and its advertising agency DDB Needham，were the long - distance wester n routes where ridership had been declining significantly.At one time，trains w ere the only practical way to cross the vast areas of the west.Trains were fast，ver，'luxurious，and quite convenient compared to other forms of transportation existing at the time.However，times change and the automolile became America's standard of convenience.Also，air travel had easily established itself as the fastest method of traveling great distances .Therefore，the task for DDB Needham was to encourage consumers to consider other aspects of train travel in order t o change their attitudes and increase the likelihood that trains would be consid ered for travel in the west.Two portions of the total market were targeted: 1) anxious fliers - those concermed with safety，relaxation，and cleanliness and 2) travel - lovers - those viewing themselves as relaxed，casual，and interested in the travel ecperience as part of their vacation.The agency then developed a campaign that focused on travel experiences such as freedom，escape，relaxation，and enjoyment of the great western outdoors.It stressed experiences gained by u sing the trains and portrayed western train trips as wonderful adventures.Adver tisements showed pictures of the beautiful scenery that could be enjoyed along s ome of the more famous western routes and emphasized the romantic names of some of these trains(Empire Builder，etc.).These ads were strategically placed among family - oriented TV shows and programs involving nature and America in order t o most effectively reach target audiences.Resultswere impressive.The Empire Bu ilder.Which was focused on in one ad.enjoyed a 15 percent increase in profits on its Chicago to Seattle route.

Questions 36 to 40 are based on the following passage:
Why does cream go bad faster than butter? Some researchers think they the answer，and it comes down to the structure of the food，not its chemical composition - a finding that could help rid some processed foods of chemical preservatives.C ream and butter contain pretty much the same substances，so why cream should sou r muchfaster has been a mystery.Both are emulsions - tiny globules(小球)of one liquid evenly distributed throughout another.The difference lies in what's in the globules and what's in the surrounding liquid，says Brocklehurst，who led the investigation.In cream，fatty globules and what's in the surround ing liquid，says Brocklehurst，who led the investigation.In cream，fatty globul es drift about in a sea of water.In butter，globules of a watery solution are l ocked away in a sea of fat.The bacteria which make the food go bad prefer to li ve in the watery regions of the mixture.”This means that in cream，the bacteria are free to grow throughout the mixture，”he says.When the situation is revers ed，the bacteria are locked away in compartments (密封仓) buried dee p in the sea of fat.Trapped in this way，individual colonies cannot spread and rapidly run out of nutrients.They also slowly poison themselves with their wast e products.”In butter，you get a self - limiting system which stops the bacteri a growing，”says Brocklehurst.The researchers are already working with food com panies keen to see if their products can be made resistant to bacterial attack t hrough alterations to the food's structure.Brocklehurst believes it will be pos sible to make the emulsions used in salad cream，for instance，more like that in butter.The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.
36. The significance of Brocklehurst's research is that ______ .
A) it suggested a way to keep some foods fresh without preservatives
B) it discovered tiny globules in both cream and butter
C) it revealed the secret of how bacteria multiply in cream and butter
D) it found that cream and butter share the same chemical composition
37. According to the researchers.cream sours faster than butter because bacteria_____ .
A) are more evenly distributed in cream
B) multiply more easily in cream than is butter
C) live on less fat in cream than in butter
D) produce less waste in cream t han in butter
38. According to Brocklehurst，we can keep cream fresh by ______ .
A) removing its fat B) killing the bacteria
C) reducing its water content D) altering its structure
39. The word“colonies”(Line 2，Para.4) refers to ______ .
A) tiny globules B) watery regions
C) bacteria communities D) little compartments
40. Commercial application of the research finding will be possible if s alad cream
can be made resistant to bacterial attack ______ .
A) by varying its chemical composition B) by turning it into a solid lump
C) while keeping its structure unchanged D) while retaining its liquid form
