Exercise 3:Read the passage carefully and, choose the correct answer.
The scarcity of tigers and African elephants is more and more serious. They are endangered because
poachers hunt them in order to sell tiger pelts and elephant ivory.
At least 4,000 elephants are killed each year in order to meet the global demand for elephant ivory, which is
used to make carvings, jewelry and other products although it is illegal to sell ivory since 1989 anywhere.
"Americans should be aware that there is still a problem with elephant poaching and loss to the illegal
ivory trade," Ginette Hemley, Fund's vice president for species conservation, told The Washington Post in
September. And so our message is, 'Don't buy it, and don't take that chance'."
A Wildlife Fund report states that the United States seized 8,300 illegal ivory items between 1995 and
2002. Each week there are about 1,000 ivory auctions; the report said.
As for tigers, their parts are used in traditional Chinese medicine. Tiger bones are used as a pain reliever in
traditional medicine. Even tiger's whiskers are sold because some people in Asia think they are a good-luck
charm - like a rabbit's foot in the United States. "Part of our job is education," said Professor Dillon. "The
other part is law enforcement. So we have more than one strategy."

We are all slowly destroying the earth. The seas and rivers are too dirty to swim in. There is so much
smoke in the air that it is unhealthy to live in many of the world’s cities. In one well-known city, for example,
poisonous gases from cars pollute the air so much that traffic policemen have to wear oxygen masks.
We have cut down so many trees that there are now vast areas of waste-land all over the world. As a result,
farmers in parts of Africa cannot grow enough to eat. In certain countries in Asia there is too little rice.
Moreover, we do not take enough care of the countryside. Wild animals are quickly disappearing. For instant,
tigers are rare in India now because we have killed too many for them to survive. However, it isn’t enough

simply to talk about the problem. We must act now before it is too late to do anything about it. Join us now.
