阅读理解。     LONDON: What could possibly be wrong with planting trees? The benefits are obvious; they
firm the soil, take in extra water and take carbon dioxide out of the atmosphere. However, it now
turns out that planting trees could add to global warming.
     Tree roots do a great job of keeping soil firmly on the ground and out of the wind"s power. The
problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
     Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia.
Tons of dust are lifted as a thin film over the oceans surface. The dust fuels oceanic life.
     Dust from China is carried east and left in the Pacific Ocean. If a tree-planting program there is
successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked
away in the ocean.
      Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past
few years studying dust and says his work "shows clearly the complexity of the system and the
importance of not tinkering (粗劣地修补) with it without understanding the results. For this reason
the need is to focus on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the
land surface."
     An American scientist, Robert Jackson, has shown that when native grassland areas are invaded
(侵入) by trees, carbon is lost from the soil. "We are studying why the soil carbon disappears, but
one theory is that trees do a lot more of their growing above ground compared to grasses, so less
carbon goes directly into the soil from trees." says Jackson.
      In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to
be outweighed by the loss of carbon from the soil below ground. Countries that plan to combat global
warming by planting trees may have to think again.
     Solutions to environmental problems are often more complex than they first appear, and
understanding the Earth"s climate is a very great challenge.1. According to this report, dust from storms can do the following except ________.A. harm the earth"s climate    
B. take in carbon dioxide  
C. feed the life in the ocean    
D. keep carbon dioxide locked in the ocean2. Andy Ridgwell believes that _____________.A. dust plays a more important part than trees
B. trees shouldn"t have been planted in the past
C. carbon dioxide is harmful to everything on the earth
D. environmental problems are far less simple than expected3. Robert Jackson"s experiment proves that ____________.A. grassland areas should be covered by forests
B. carbon can turn grass into dust
C. trees hold more carbon than grasses
D. less carbon can make trees grow faster4. The underlined word "combat" in the last but one paragraph means ________________.A. learn about

came later for her, said Duret, who was handed dry clothes from onlookers. Duret caught a taxi with his
girlfriend shortly after.
     The rescue happened on the day before he left for France. Duret said he didn"t realize his story of
heroism had greatly moved New York until he was leaving the city the next morning.

阅读理解。                              Special Bridges Help Animals Cross the Road
                                                            - Reported by Sheila Carrick
     Why did the chicken cross the road? To get to the other side.
     Most people know this joke. But recently, some people have been much more worried
about how the grizzly bear(灰熊) and mountain lion can cross the road.
     "Millions of animals die each year on US roads," the Federal Highway Administration
reports. In fact,only about 80 ocelots, an endangered wild cat, exist in the US today. The
main reason? Road kill.
     "Ecopassages (生态通道)" may help animals cross the road without being hit by cars.
They are paths both over and under roads. "These ecopassages can be extremely useful, so
that wildlife can avoid road accidents," said Jodi Hilty of the Wildlife Protection Society.
     But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern
Arizona University found foot marks left by mountain lions on an ecopassage that went under
a highway. This showed that the lions used the passage.
     Builders of ecopassages try to make them look like a natural part of an area by planting
trees on and around them. Animals seem to be catching on. Animals as different as
salamanders(火蜥蜴) and grizzly bears are using the bridges and underpasses.
     The next time you visit a park or drive through an area with a lot of wildlife, look around.
You might see an animal overpass!1. The writer uses the example of "ocelots" to show that ________.A. wild animals have become more dangerous
B. the driving conditions have improved greatly
C. the measure for projecting wildlife fails to work
D. an increasing number of animals are killed in road accidents2. From the news story, we know an ecopassage is ________.A. an underground path for cars
B. a fence built for the safety of the area
C. a bridge for animals to get over a river
D. a path for animals to cross the road3. When the writer says that "Animals seem to be catching on", he means ________.A. animals begin to realize the dangers on the road
B. animals begin to learn to use ecopassages
C. animals are crossing the road in groups
D. animals are increasing in number4. The writer asks visitors and drivers to look around when traveling because________A. wild animals may attack cars
B. wild animals may jam the road
C. they may see wild animals in the park
D. they may see wild animals on ecopassages

阅读理解。     TOKYO-A child-like robot that combines the roles of nurse,companion and security guard
is to go on the market to help the growing ranks of elderly Japanese with no one to look after
them.
      The "Wakamaru" robot can walk around a house 24 hours a day,warning family,hospitals
and security firms if it perceives(notices)a problem.It will,for example,call relatives if the owner
fails to get out of the bath.
     Cameras implanted in the "eye-brows" of the robot enable it to "see" as it walks around an
apartment.The images can be sent to the latest cell phones,which display the pictures.
      Mitsubishi Heavy Industries which developed Wakamaru plans to start selling the meter-high
robots for about $15 000.
     Wakamaru,which speaks with either the voice of a boy or girl,is also designed to provide
companionship,greeting its "papa" when he comes home.
     It is the first household robot able to hold simple conversations,based on a vocabulary of
around 10 000 words.It cannot only speak but can understand answers and react accordingly.
     It will ask "Are you all right?" if its owner does not move for some time.If the answer is no,
or there is no answer,it will telephone preset numbers,transmitting images and functioning as a
speakerphone.
     Wakamaru will inform a security firm if there is a loud bang or if an unknown person enters
the house while the owner is out or asleep.It can recognize up to 10 faces . But like most robots
it cannot climb stairs.
     It can be set to remind forgetful people when it is time to take medicine,eat and sleep.
      Mitsubishi adapted Wakamaru from robots which already makes to go around nuclear power
facilities(设施).The idea to use the technology in the home came from a company employee.
     The project chief said:"Looking at the ageing of society and the falling birth rate we decide that
this could work as a business.We want to offer Wakamaru as a product that helps society.
     The technology has gained nation-wide publicity in Japan among increasing concern over how
to look after the ever-growing number of old people.The life expectancy of Japanese women has
shot up to almost 85,the highest in the world.
      At the same time,extended families are being replaced by nuclear families.This has left many
Japanese anxious about their elderly parents,whom they rarely see because of their long hours at
the office.1.Which of the following is TRUE about the Robot?A.It is used in some nuclear power facilities.
