A. True or False.
The world itself is becoming much smaller by using modern traffic and modern communica tion means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it,?drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It's bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Pollution by S02 is now the most dangerous kind of air pollution. It is caused by heavy traf fic. It is sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time.
You can make a difference on Earth Day and every day!

B. Choose the best answer.
In northern China during spring, big sandstorms often make trouble for people. Sandstorms usually happen in spring. They have happened in more than 10 provinces in northern China this year. People in southern China don't have to worry about this kind of bad weather. Most of the sand comes from the north of China. In northern China, lots of places have few trees and don't get much rain. People there have been cutting down too many trees. When there aren't many trees, the ground can't keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts, the ground becomes loose(松散的). Strong winds take the loose sand into the sky.
Sandstorms are bad for people's health. If people breathe too much sand, they could cough or have asthma(哮喘). Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear farmers' houses down.
What can you do to stop sandstorms? Here's an idea: Ask your parents to help you plant some trees this spring. If you see people cutting down too many trees, tell them about the dan gers of sandstorms, and ask your government to stop them.

The world is not only hungry,???1 ??it is also thirsty for water. This may seem strange?to you, since nearly 70% of the earth's surface is covered with water. But about 97% of that is?sea water, or salt water. Man can only drink and use ??2 ??3% — the fresh water from?rivers, lakes, underground, and other sources(源泉). And we can not even use all of that. Even worse, some of it has been made dirty.
However, as things stand today, this fresh water is still enough 3 us. But our?need for water is becoming larger and larger quickly —almost day by day. We should take steps to deal with this problem now and in this way we can get away from a serious world-wide water shortage (缺乏) later on.
We all have to learn how to stop 4 our valuable water. One of the first steps is to?develop ways of reusing it.
Today in most large cities, water is used only once and then sent out into a sewer system?(下水道). From there it returns to sea or runs into underground places. But even if every large?city reused its water, we still would not have enough. All we'd have to do to make use of sea wa ter in the world is to remove the salt. If we take these steps we will be ??5 ???no?danger of?drying up.

E. Answer the following questions.
Want a plastic shopping bag? Pay for it. That's what shoppers are told at cash counters of supermarkets, department stores and groceries across the country. Following a government order aimed at reducing pollution, retailers (零售商) stopped giving free plastic shopping bags from June 1st this year.
Plastic shopping bags do make shopping convenient, but they also harm the environment. According to the National Government and Reform Commission (NDRC), at?least 1,300 tons of oil is needed to make the bags given out by supermarkets alone every day. Plastic bags are not bio-degradable(生物所能分解的)and plastic accounts for 3—5percent of the daily waste, most of which come from plastic bags. To limit the use of plastic bags is to protect the environment.
But the question is; Can the Chinese people, who have enjoyed free plastic bags for more than ten years kick their habit? "It doesn't matter how much a plastic bag costs. What mattersis our effort to protect the environment," Wang?Yali said while packing things into a cloth bag.
But many customers think plastic bags are a necessity. "I have to use plastic bags, espe cially for fresh meat and vegetables, and I think 0. 1 yuan for a bag is acceptable," a woman surnamed Ye said.
What's your opinion then?
