Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation (聚集)of plastic in the ocean endangers marine life and pollutes the water.

Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean.

One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s.

The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are:

1. There are no fish here because of the lack of nutrients.

2. The zone also lacks the wind that is essential for sailing.

To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion(入侵)of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain.

To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics.

1. What can we learn from the first paragraph?

2. What is the direct influence of the plastic continent?

3. It is implied that the work of plastic recycling proves to be ______.

4.What can we learn from the passage?

高三英语单项填空中等难度题查看答案及解析

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.

There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.

Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.

These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.

We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.

The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

1. How many examples of environmental problems are given in the first paragraph?

A. 2                             B. 3                    C. 4                              D. 5

2. Which of the following is TRUE according to the passage?

A. In all there are three kinds of pollution

B. If people continue to pollute our planet, there will be no trees.

C. Industrial pollution has been completely controlled.

D. Laws have been passed to stop pollution and protect our environment.

3. The sentence “We hope that all these measures will be effective and bring back a healthy environment” can best be put at the end of paragraph _____.

A. 2                             B. 3                    C. 5                              D. 6

4. The writer’s attitude towards the future of the earth is _____.

A. despair                  B. negative          C. optimistic                  D. hopeless

高三英语单项填空中等难度题查看答案及解析

Airborne dust is normally seen as an environmental problem, but the lack of it is making air pollution over China considerably worse.

A new study suggests less dust means more solar radiation hits the land surface,which reduces wind speed. That lack of wind in turn leads to an accumulation of air pollution over heavily populated parts of China. The researchers found that reduced dust levels cause a 13% increase in human-made pollution in the region.

Hundreds of millions of people across China continue to be impacted by air pollution from factories and coal-fl red power plants. Studies suggest that the dirty、air contributes to 1.6 million deaths a year, about 17% of all mortalities. But this new research says that the human-induced pollution is being made worse or better by naturally occurring dust that blows in from the Gobi desert. Using models to simulate 150 years of wind and dust patterns in the region, the researchers found that the dust deflects significant amounts of sunlight. Without it, more heat from the Sun hits the land. Differences in the temperatures between land and sea cause the winds to blow. Without the dust, the land warms up more and that changes the temperature differential with the sea leading to weaker breezes - and more air pollution.

“There are two dust sources. One is the Gobi and the other is the highlands of north-west China, but we found the Gobi had much more influence," said lead author Yang Yang, from the Pacific Northwest National Laboratory in Washington State, US. “Less dust in the atmosphere causes more solar radiation to reach the surface. It weakens the temperature difference between the land and the sea and impacts the circulation of the winds and causes a stagnation over eastern- China and that causes an accumulation of air pollution.”

Another study has recently shown a link between declining Arctic sea ice and a major air pollution event in China. The authors of the new study believe that both theories could be true.

“Our study has the same mechanism: the weakening of winds causes more pollution, and what is behind this needs to be studied/ said Yang Yang, “We have two views on this kind of weakening of wind. They found the sea ice, we found the dust-wind interaction can also lead to weakening of the wind. I think both of them are important.”

The researchers believe that the study may inform broader questions about how natural human-created aerosols interact.

Many parts of the world, in addition to China, are now suffering from increased levels of air pollution and understanding how dust, winds and emissions work together may help limit some of the worst impacts of dirty air.

One of the key lessons from this study is that the absence of dusty conditions could mean the air you are breathing is worse for you, not better.

1.According to the new study, the formation of air pollution over heavily populated parts of China is due to_________.

A.the accumulation of dust B.the shortage of wind

C.the high level of living standards D.the rise of temperature

2.Whats the right sequence of cause and effect leading to the air pollution?

①the worse circulation of the winds

②more heat from the sun

③lessening temperature between the land and the sea

④less dust

⑤a worse stagnation

A.④②③①⑤ B.①④②⑤③

C.④①③②⑤ D.①⑤②④③

3.What might Yang Yang agree with?

A.Lack of dust from the highlands of north-west China means we can breathe better air.

B.There is little connection between declining Arctic sea ice and air pollution in China.

C.Declining Arctic sea ice and dust-wind interaction can cause weakening of the wind.

D.The interaction between dust, winds and emissions can worse dusty conditions.
