Like many countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.

Today, London is much cleaner but there is a new problem: smog from cars. In December 1991, there was very little wind in London and pollution increased. As a result, about 160 people died from pollution in just four days.

Part of the problem is the new "out of town" shopping centres. In the past, people often walked to shops near their homes or went by bus. Now, many people drive to the new shopping centres. The small shops have disappeared and more people have to travel to do their shopping.

Many people are trying to reduce the use of cars in Britain. Some cities now have special bicycle lanes, so people cycle to work. Some people also travel to work together in one car to reduce pollution and costs.

A. The government once introduced a law against smog from cars and factories.

B. London is much cleaner than before, so nobody dies from pollution any longer.

C. Now smog in London mainly comes from cars.

D. People in cities now go to work by bicycle only.

2. Why do people drive to go shopping?

A. They prefer shops in big shopping centres outside of town.

B. Small shops near their homes have disappeared.

C. Many new shopping centres have appeared outside of town.

D. It has become popular to do shopping in large shopping centres.

3. How many examples are there in the passage of people reducing car use?

A. Two.

B. Three.

C. Four.

D. Five.

4. The word "improved" in the first paragraph probably means

A. got worse

B. reduced

C. became better

D. maintained

5. What is the best title for this passage?
