A. The; the B. /; the

C. A; the D. a; a

试题分析:考查冠词。句意:除非我们创造一个少一些污染的世界,否则我们永远不能期望得到一个更蔚蓝的天空 。用不定冠词表示泛指,a bluer sky一个更蓝的天空,a less polluted world.一个少一点污染的世界,因此两个空都用不定冠词,故D正确。

考点:考查冠词

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 (反应) 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 muds. 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 aero-planes. Rivers tend to 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.The underlined phrase “mopping up” in the second paragraph means ____.

A. cleaning up B. taking in

C. wiping out D. giving out

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

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

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

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

D. There is no exact answer up to present.

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.The best title for this passage may probably be _____.

A. Studies of the Amazon

B. Climates of the Amazon

C. Secrets of the Rainforests

D. Changes of the Rainforests

They baby is just one day old and has not yet left hospital. She is quiet but alert (警觉). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise (同样地) when the researchers started with drumbeats and moved to spots.

1.The experiment described in Paragraph 1 is related to the baby’s .

A. sense of sight B. sense of touch

C. sense of hearing D. sense of smell

2.Babies are sensitive to the change in______.

A. the size of cards B. the colour of pictures

C. the number of objects D. the shape of patterns

3.Why did the researchers test the babies with drumbeats?

A. To reduce the difficulty of the experiment.

B. To carry their experiment further.

C. To see how babies recognize sounds

D. To keep the babies’ interest.

4.Where does this text probably come from?

A. Science fiction. B. Children’s literature.

C. A science report. D. An advertisement.
