The world itself is becoming much smaller by using modern traffic and modern communication means (通讯设备). 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 kind of pollution. Water pollution kill our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is from heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.

_______________________________________________________
2.How many kinds of pollution are mentioned in the passage?

People depend on plants. We use plants for food, cloth, shelter (住处), and even the air we breathe (呼吸).
Plants keep our air and water clean. Green plants give us oxygen (氧气). Oxygen is part of the air we breathe.
Plants are also part of the water cycle (水循环). Most of the water that a plant takes in goes back into the air.
Plants give us a lot of the food on the earth. Fruits, vegetables, and grains (谷物) come from plants. Without plants, we would not have bread, rice, carrots, apples, oranges, or bananas! Many people are growing plants to eat in their own gardens at home. Having your own garden helps the earth as well.
When you grow your own fruits and vegetables, you help cut down on pollution because big trucks don’t need to take your food to shops. You also help reduce the amount of rubbish because you don’t need to use bags for packing your food. You can just pick it out of the ground or off a plant and put it into a basket!
Trees are an important plant resource (资源). Trees provide wood to build homes and furniture. Trees are used to make lots of things around your home and at your school. And trees provide fruits that are good for you. Without trees, the earth would be a very different place.
1.________ is part of the air we breathe.
A.Sunlight B.Water C.Food D.Oxygen

When you think of the Arctic (北极), you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. “And now”, CNN says, “It’s the Arctic’s turn.”
German scientists have recently found microplastics in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1800 pieces of microplastics per liter of (每升) snow.
How is plastic pollution reaching the Arctic? According to scientists, “It’s clear that most of the microplastics in the snow come from the air.” They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.
Are they bad for us? Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What’s more, earlier studies have shown that microplastics may contribute to lung cancer risk.
Microplastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystems along the way. They start in our wastewater, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we’re eating the plastic as well.
1.We can learn from Paragraph 1 that________.
A.the Arctic is the last really clean place left on earth
B.the Arctic is an icy land of pure white snow
C.the Arctic is a beautiful icy land with clean air
D. the Arctic has been polluted by plastic rubbish
2.The underlined word “contribute” means “_______” in Chinese.
A.增加 B.捐献 C.造成 D.是……原因之一
3.Where do most of the microplastics in the snow come from?
A.From water. B.From air. C.From wind. D.From food.
4.Which of the following isn’t true?
A.We may breathe microplastics in Arctic.
B.Microplastics may cause lung cancer.
C.We don’t have to mind microplastics right now.
D. Microplastics have hurt ecosystems.
5.How does the writer end this passage?
A.By advising us to drink clean water.
B.By asking people not to eat sea animals.
C.By telling the seriousness of plastic pollution.
D.By showing the beauty of Arctic.
