三、阅读理解
London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today. In fact, the “fog” was smog, a mixture (混合物) of smoke and fog. In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same kind of problem of air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.
26．What was the main reason for air pollution in London
A．There was too much smoke in the sky. B．There were too many factories in the city.
C．People burnt too much coal in the houses. D．Lots of people smoked at home.
27．How did the air in London become much cleaner
A．There was not so much fog in the winter later.
B．A law was made to stop people from burning coal in their houses.
C．Many factories in the city were closed.
D．Some of the factories moved away.
28．What does the underlined word “pea-soupers” refer to (指)
A．Coal. B．Smoke. C．Gas. D．Smog.
29．How many reasons make it more difficult for Chinese cities to solve the problem of air pollution
A．One. B．Two. C．Three. D．Four.
30．Which of the following sentences is not true
A．Using coal is much more expensive than using gas.
B．Factories made much more pollution in China.
C．The reasons for air pollution in London and Beijing are different.
D．The Chinese government has taken action to cut down air pollution.
四、选词填空
shop, make, many, throw, how, it, give, badly, careful, use
Dear sir, I would like to make a comment(评论) on the plastic(塑料) bags which we use in our daily life.
I thought that the ____31____ effect(影响) from all these bags on our environment was well-known and that most people know they should not keep ____32____ them but collect them in the dustbin(垃圾箱). However, one of the ____33____ near my home seems to use ____34____ bags than before. Red ones, white ones and blue ones—it ____35____no difference.
