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.

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.

people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is
becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert? Scientists think that people make deserts. People are doing
bad things to the earth.
Some places on the earth don"t get much rain. But they still don"t become deserts. This is because some
green plants are growing there. Small green plants and grass are very important to dry places. Plants don"t let
the sun make the earth even drier. Plants do not let the wind blow the dirt away. When a bit of rain falls, the
plants hold the water. Without plants, the land can become desert more easily.

small town in California found a happy answer.
Very 3 rain ever fell there. The town had no water 4 . The water it used was 5 from a river 300
miles away. As more people 6 live in the town, more water was needed. Now water has to be brought in
from 600 miles away. All these cost a lot of money.
The town 7 a plan. It found ways to clean its "dirty" water. Once the cleaned water was reused 8
many ways. Five man-made lakes were built. Here people could swim and fish and go 9 . They could have
picnics in their new parks. Farmers had more water for their crops. New factories can be built,now that they
have the promise of enough water.
In most places, water is used and thrown 10 . The town that saved its water has saved the town!
