2. Reading comprehension阅读理解………………
The area of desert in the world is growing every year. Many parts of the
world, which once had large populations and produced plenty of crops,have
become deserts. Dunhuang in China, deep in the heart of the Gebi Desert,
was once a great city.
Cattle are one cause of the problem. In good years, farmers increase the
numbers of their cattle. Then one year, the rains fail to come. The farmers do
not want to kill any of their cattle, so the cattle eat all the grass and anything
that grows on poorer land. If this continues for several years, the grass never
grows again and the land becomes a desert. One suggested answer is for farm
ers to limit the numbers of their cattle.
Another problem is that good soil is gradually lost. When trees are cut
down, there is nothing to hold the soil in place on the hillside. So when it
rains, the soil is washed down the hills and /into/ the rivers. Strong winds can
also blow away the valuable soil that lies on the top of the fields.
Air pollution comes from factories, power stations and cars. Chemicals in
the smoke from power stations cause a lot of damage. They can travel hundreds
of miles in the wild, before falling to the ground in the rain. But this“chem
ical rain" gradually destroys trees in the forests and kills fish in the lakes. In
Germany, over 50% of the country's trees had been damaged by the year 1986.
Time and time again there are serious accidents that pollute the air. In
1986 there was a bad accident at a nuclear power station in Russia. A cloud of1986
radiation crossed the whole of Europe. It is said that 125,000 people died in
Russia as a result of illnesses caused by the accident.
In 1984 there was a serious accident at a factory in India and a cloud of
dangerous gas covered the town of Bhopal. Over 2500 people were killed that
night, and hundreds of thouands of people were injured. Many of the injured
lost their sight.
Water pollution is caused by waste from factories and cities. Oceans are
able to clean themselves, but certain seas, once they become dirty, are not able
to do so. One example is the Mediterranean which lies between Europe and Africa.
It has only one narrow entrance to the ocean in the west. One quarter of the
shores of the Mediterranean are polluted and are no longer safe for swimming,
as a lot of diseases are present in the water. In most places it is not safe to eat
Lakes also have the same problems. Lake Baikal in Asia was once the
cleanest in the world, with over 700 different kinds of plant and animal life.
Now,however, the waters of this great lake, which is also the world's deepest
(over 1,740 metres), have been dirtied by waste from a chemical factory.
In 1989 an oil tanker hit a rock off the northwest coast of Alaska. 35,000
tons of oil poured /into/ the sea. The accident was one of the worst in history.
More than 34,000 birds and 10,000 animals were killed. 4,800 square kilo
metres of ocean were polluted.
