题目内容

 The hole in the earth's protective ozone layer(臭氧层)won't repair itself until about two decades later than had been expected, scientists announced.

The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation(紫外线辐射), helping to make life on Earth possible. For many dacades, ozone was depleted(削减) by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.

Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere(平流层)over the past 27 years.

The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.

Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate(估计)ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.

Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.

1.According to the passage, the ozone layer _______

A.absorbs as much as sunlight as possible

B.protects man against ultraviolet radiation

C.controls the changes in temperature

D.prevents the production of carbon dioxide

2.The improved computer model is believable because _________

A.it was once proved by facts

B.it has been studied for 27 years

C.it was created by many scientists

D.it is related to satellites and airplanes

3.The underlined word “they” in the fifth paragraph refers to ________

A.the levels of ozone

B.ozone-depleting gases

C.the ozone holes

D.the areas far from the poles

 

【答案】

1.B

2.A

3.B

【解析】

试题分析:

1.B 细节题。根据第二段1,2行The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation(紫外线辐射), helping to make life on Earth possible.说明B正确。

2.A 细节题。根据第三段2,3,4行The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere(平流层)over the past 27 years.说明该模型在过去的27年中得到了证明,故A正确。

3.B 推理题。根据本句This new method allows us to more accurately estimate(估计)ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.

说明这里的they是指ozone-depleting gases,故B正确。

考点:考查环境类短文阅读

It was on a warm day last summer. I was walking by the sea. The waves came and went. But I didn’t see them. I was lost in my thoughts.

A row of small holes soon caught my eyes. They lay in the sandy earth by the side of a road. In a minute I would have stepped on them.

What are these holes? I wondered. It had an answer soon. A fat, hairy insect crawled up from the earth. It had a wide tail. It was using the tail to dig in the ground.

The insect moved round and round in one spot(地点). Soon it had made another hole. When it was finished, the insect hid at the bottom. It covered its head with sand.

By now my thoughts of the early morning had gone. This new hole and the insect were all my world. So I sat quite still by the side of the road. And I waited.

As I watched, a small ant crossed the road. It passed my foot, and then it crossed the sandy earth. In a little while it reached the edge of the hole. I saw it start to fall in. The ant tried to turn back. But it couldn’t.

And then I knew. I knew why the holes were there. For just then the fat insect came up out of the hole. It ate the ant who was trapped there.

Later I learned the insect’s name. It’s called ant lion. It digs holes to catch ants.

I’ll never forget that day. The holes looked so small to me. But to the ant and the ant lion they were the whole world.

I took my walks by the sea that summer. But I never again learned as much as I did on the one.

1. What did the ant lion use to dig holes?

  A. Its tail       B. Its feet.            C. Its head         D. Its whole body

2. Why did the ant lion hide in the hole?

  A. To keep the sun away           B. So no one would catch it.

  C. So the ant wouldn’t see it        D. To keep warm.

3. Why did “I” sit down by the side of the road?

  A. To think                           B. To eat her lunch

C. To watch the little holes          D. To catch ants.

4.Why did the ant lion dig the holes?

  A. To play a game                 B. To catch its food

  C. To hide its eggs                   D. To hide from its enemy

5.Why did “I” never forget that day?

  A. Learned something          B. Had a nice time

  C. Saw the ant lion whenever she took a walk

  D. Felt sorry for the ant.
