They hang from trees. They float in rivers and oceans. They are piled up in landfills(垃圾填埋场). Our frequent use of plastic products has, for many years, been a leading cause of serious environmental problems in the world. Last month, China drew up new guidelines(指导方针) aiming to bring plastic pollution under control across the country in five years’ time.

According to the new guidelines, the ban(禁令) on the use of non-biodegradable(不可生物降解的) plastic bags will have been applied to cities including Beijing and Shanghai by the end of this year. Other sources of plastic garbage will have been banned in these cities by the end of 2022. And that rule will have extended nationwide by late 2025.

Fortunately, China will not start from zero. Late last year, the country announced a national standard for biodegradable plastic shopping bags. It is technologically prepared for their production. Some regions have gained valuable experience that others can learn from. For example, Jilin province is leading the way by providing eco-friendly(环保的) shopping bags in some local supermarkets.

Given the size of China’s consumer market, one main obstacle(障碍) is the large number of plastic items that are being used by restaurants and e-commerce(电子商务) platforms. It’s estimated that nearly 25 billion plastic bags were used for deliveries in 2018. Most of them were rarely reused.

However, most Chinese people welcomed the government’s effort to reduce the use of plastics. “Beijing is thinking about the problem seriously,” said Tang Damin, a member of Greenpeace East Asia in Beijing. He added that the policy could be far more effective(有效) by using incentives(激励) such as a deposit(押金) return program on plastic products.

1.What does the writer want to tell us?

A.China has invented biodegradable plastic shopping bags.

B.Plastic pollution becomes more and more serious in China.

C.Greenpeace East Asia in Beijing worries about the plastic pollution.

D.China has drawn up new guidelines to reduce plastic pollution in five years.

2.According to the time line of the new guidelines,　　　 .

A.the rules will have extended nationwide by late 2025

B.plastic garbage will have been banned in Shanghai by the end of 2020

C.plastic bags won’t be allowed to be used in Beijing by the end of 2022

D.a deposit return program on plastic products will be put into practicing in 2023

3.What is the biggest challenge to follow the guidelines?

A.Most Chinese people aren’t used to using paper bags.

B.It’s hard to make effective policy to solve the problem.

C.Many supermarkets are still providing customers with plastic bags.

D.Restaurants and e-commerce platforms need large number of plastic items.

4.What does Tang Damin think of the new policy?

A.The new guidelines are not much useful.

B.People should be encouraged to follow the policy.

C.The new policy can help a lot to develop Greenpeace.

D.Beijing is thinking about the plastic pollution seriously.

5.After reading the passage, we can infer that　　　 .

A.people will order more take-out food

B.plastic bags will be widely reused in the world

C.biodegradable plastic shopping bags will become popular

D.there will be more people using paper products in the future

Once upon a time, a hippo lived in a river next to a big tree.

九年级英语单选题中等难度题查看答案及解析

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

1.The most important points of trees to man is ________.

A. they help him to make money

B. they give him cool

C. they give him wood and other things

D. they help him to stop drought and floods

2.In many places forests slowly disappear because ________ .

A. many trees have been cut down by man

B. new trees are not well looked after

C. man has not paid enough attention to planting trees

D. all the above

3.Land becomes desert after all trees are cut down because ________ .

A. roots of trees break up the soil

B. there are too many rainfalls

C. strong winds bring a lot of sand

D. there are no longer trees to keep the rain and protect the top-soil.

4. Which title best fits the passage?

A. Trees and Man.

B. The Function of Tree Wood.

C. How do People do with Trees?

D. The Usage of Tree Roots.
