阅读理解。     Illegal removal of coral (珊瑚) along Sri Lanka"s coastline increased the amount of destruction on the
island by last December"s tsunami, say researchers.
      Harindra Fernando, a fluid dynamicist (力学家) at Arizona State University in Tempe, made the connection
after a visit to his native Sri Lanka earlier this year. While serving as a scientific expert and translator for a
BBC-documentary team, he chatted with locals who said they saw the tsunami turn sideways when it hit
coral-which would have made it less powerful than in coral-free areas. Fernando linked this to trucks he had
seen last year carrying piles of coral away from the sea.
      Using the eyewitness reports, estimates (估算) of wave heights, and a series of divers to check the
presence or absence of corals, Fernando and his colleagues produced a map of coral gaps and wave flooding
along Sri Lanka"s southwest coast. 
     The tsunami reached significantly farther inland through the gaps: in one instance, the water traveled 1.5
kilometres long and knocked a passenger train off its tracks, killing 1,700. But only a few kilometers away,
where the coral was still undamaged, the wave travelled just 50 metres inland and caused no deaths.
      There is a similar phenomenon. In Nicaragua in 1992, a tsunami poured through a break in the coral reef
made to let boats through. "Within this passage, water went one kilometre inland," says Fernando. "But nearby,
where the coral was undamaged, there were still beach umbrellas standing."
      In Sri Lanka, coral is illegally mined to provide souvenirs for tourists, or to be used in house paint. Coral
harvesters sometimes blow it up with dynamite (炸药) in order to collect fish at the same time. Often, the
reefs in the best shape are those in front of hotels, as the hotel owners maintain them for the tourists. Fernando
hopes that his findings will encourage the Sri Lankan government to enforce (实施) its laws against coral
mining. 1. Harindra Fernando did all the following EXCEPT _____.

[     ]

A. serving as a translator for a BBC-documentary team
B. helping the Sri Lankan government enforce its laws against coral mining
C. producing a map of coral gaps along Sri Lanka"s southwest coast

B. coral-free area is a danger to passenger trains
C. in general, water travels 30 times farther inland in a coral-free area
D. it is urgent to enforce laws against coral mining 3. Which of the following may NOT be the cause of coral gaps?

[     ]

A. Boat passages.

阅读理解。    The food we eat seems to have a great effect on our health. Although science has made big steps in
making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has
shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related
to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized
that things commonly used to keep colors in meats and other food additives caused cancer. Yet, these
additives remain in our food, and it is difficult to know which things on the wrappings of foods are helpful
or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals,
and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to
animals not for their health, but just to make a profit. 
    The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although
some countries have tried to control such things, the practice continues. 1. According to this passage, we can know _____. [     ]
A. perhaps most of human illness is caused by what we eat
B. perhaps most kinds of cancer are related to what people eat
C. cancer was discovered in 1945
D. science has made food unfit to eat 2. Things that are used to keep colors in meats are _____. [     ]
A. harmful
B. useless
C. helpless
D. dangerous 3. All the additives _____. [     ]
A. are bright and colorless
B. are not bright and colorful
C. have indirect effects on our health
D. have direct effects on our health 4. People use additives _____.[     ]
A. to make food more unfit to eat
B. to improve the color and taste of the food
C. to change the color of the food
D. to take off the diseases of the food 5. Which of the following is NOT true? [     ]
A. Some wrappings of food are harmful.
B. Farmers try to make more money on the market by fattening their animals.
C. "The practice continues" means "things are still going on like that".
D. We needn"t take care of what we eat.
