Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted to the cold, dry climates of the ice ages, but until now, no one has reached a satisfying answer.

Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier, will it still survive and continue to draw down CO2 ?

Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past. Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake mud. Going back to the last ice age means drilling deep down into lake sediments （沉淀物）which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled（未取样）.So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.

1.What does the underlined phrase “mopping up” in the second paragraph mean?

A. Giving up. B. Giving out.

C. Wiping out. D. Taking in.

2.How will the Amazon rainforest react to future climate change?

A. It’ll get drier and continue to remove CO2 .

B. There is no exact answer up to present.

C. It’ll get warmer and then colder and drier.

D. It’ll remain steamy, warm, damp and thick.

3.What’s the main idea of the last paragraph?

A. It’s important to drill deep down into lake sediments to collect information.

B. It’s impossible to prove how climate changes in the Amazon rainforest.

C. It’s hard to collect information for studies of the past climate in the Amazon rainforest.

D. It’s necessary to have specialized equipment and machinery to study the past climate.

4.What is the best title for this passage?

A. Studies of the Rainforests

B. Climates of the Amazon

C. Secrets of the Ice Age

D. Changes of the Rainforests

高三英语单项填空中等难度题查看答案及解析

I am traveling home. It is bitterly cold and snowy, but the warm train is right on time. I feel pleasantly satisfied as I look out at the rush hour traffic on the motorway. I feel more satisfied as the smell of fresh coffee announces the arrival of the drinks service. Swiss friends often tell me, proudly, that their rail service is the best in the world, but recently, one experience has proved that the great Swiss love affair with their railway has turned a little sour.

It all began with the decision to end ticket sales on trains. One cold morning I arrived at my local station only to find that the ticket machine was broken. No matter, I thought, I have got a smart phone, and I hurriedly set about buying my ticket that way. This was not as easy as I had expected, busying myself between credit card and phone with freezing cold fingers, but, by the time I got on the train to Geneva I had an e-ticket and I proudly showed it to the conductor. Unfortunately she told me that my ticket was not valid. Several weeks later a letter arrived from Swiss railways together with a fine for 190 francs ($ 210).

The good people there tell me the formal payment for my ticket from my credit card company arrived four minutes after my train left the station. That means, they say, that I bought my ticket on the train—and that is strictly prohibited.

Swiss railways say their policy is designed to protect honest ticket-paying passengers, but a quick look at their balance sheet suggests something else. The company is making about $2 million a month from fines.

Although train travel is still popular, those seats do not feel as comfortable; the coffee does not smell quite so good—because Swiss railways have lost, for now anyway, something far more precious than $2 million a month: good relations with their customers.

1.What can we learn from paragraph 1?

A. The Swiss trains usually come late.

B. Traffic on the motorway goes smoothly.

C. The author hates traveling on the Swiss train.

D. The author is generally pleased with the Swiss rail service.

2.Why did the conductor say that the author’s e-ticket was invalid?

A. It was purchased online.

B. It was paid for after the train’s departure.

C. It was purchased on a ticket machine.

D. It was paid on a smart phone.

3.What does the author want to show by telling the experience?

A. The fine was unfair.

B. The conductor was impolite.

C. E-tickets are getting popular.

D. Credit cards can be inconvenient.

4.What does the author think of the new policy of Swiss railways?

A. It attracts more people to travel by train.

B. It makes the company lose a lot of money.

C. It damages company-customer relations.

D. It protects honest ticket-paying passengers.

The wonderful experiment I am going to introduce proves that air is just all around and that it presses down upon us. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.

The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！

What you need:

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method:

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4）Quickly sit the egg on the neck of the bottle.

Result:

Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

Why it happened

As the paper burns, it needs oxygen and uses up the oxygen（air）in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.

1.Why is there the need to take care when you are doing the experiment?

A. The bottle could break.

B. You need to light the paper with a match.

C. The egg needs to be shelled.

D. The egg has to be perfectly placed on the neck of the bottle.

2.In the experiment, the burning inside the bottle can ________.

A. equalize the air pressure inside and outside

B. make a seal in the neck of the bottle

C. finish up the oxygen inside the bottle

D. produce more oxygen inside the bottle

3.How was the egg put into the bottle?

A. The oxygen inside the bottle sucked the egg in.

B. It became salt without the shell.

C. The neck of the bottle was wide enough.

D. The outside air pressure forced it into the bottle.
