PartReading Comprehension(35 minu tes)
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)nowone might crash into Earth and destroy life as we know itsay 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 onethe scientists saywe'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 fallit would be the end of the world.“If we don't take care of these big asteroidsthey'll take care of us,”says one scientist.“It's that simple.”?
The curethoughmight 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.

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
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

to happen in our lifetime
D) workable solutions still have to be found to prevent a collision of asteroids
with Earth.

Questions 26 to 30 are based on the following passage:
Believe it or notoptical 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 stripescalled chevrons (人字形)painted on the roads make drivers think that they are d riving faster than they really areand 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 accidentsthe foundation will conduct its tests in areas where speed - related hazards are the greatest - curvesexit slopestraffic c irclesand bridges.Some studies suggest that straighthorizontal bars painted across roads can initially cut the average speed of drivers in half.Howevert raffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevronsscientists saynot 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

Questions 36 to 40 are based on the following passage:
Why does cream go bad faster than butter? Some researchers think they the answerand it comes down to the structure of the foodnot its chemical composition - a finding that could help rid some processed foods of chemical preservatives.C ream and butter contain pretty much the same substancesso 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 liquidsays Brocklehurstwho led the investigation.In creamfatty globules and what's in the surround ing liquidsays Brocklehurstwho led the investigation.In creamfatty globul es drift about in a sea of water.In butterglobules 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 creamthe bacteria are free to grow throughout the mixture,”he says.When the situation is revers edthe bacteria are locked away in compartments (密封仓) buried dee p in the sea of fat.Trapped in this wayindividual colonies cannot spread and rapidly run out of nutrients.They also slowly poison themselves with their wast e products.”In butteryou 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 creamfor instancemore 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.

A) it suggested a way to keep some foods fresh without preservatives

40. Commercial application of the research finding will be possible if s alad cream
can be made resistant to bacterial attack ______ .
