It was Saturday when the entire summer world was bright and fresh. Tom looked at the fence, which was long and high, feeling all enthusiasm leaving him. He dipped his brush into the whitewash before moving it along the top board of the fence. He knew other boys would arrive soon with all minds of interesting plans for this day. As walking past him, they would tease him for having to work on a beautiful Saturday—which burnt him like fire.

He, putting his hands into his pockets and taking out all he owned with the expectation of letting someone paint, found nothing that could buy half an hour of freedom. At this dark and hopeless moment, a wonderful idea occurred to him, pouring a great bright light into his mind. He took up his brush and continued to work pleasantly with calm and quietness.

Presently, Ben Rogers came in sight—munching an apple and making joyful noises like the sound of a riverboat as he walked along. Tom went on whitewashing, paying no attention to the steamboat. “Hello!” Ben said, “I’m going swimming, but you can’t go, can you?”

No answer. Tom moved his brush gently along the fence and surveyed the result. Ben came nearer. Tom’s mouth watered for Ben’s apple while he kept painting the fence.

Ben said, “That’s a lot of work, isn’t it?”

Tom turned suddenly saying “Here you are! Ben! I didn’t notice you.”

“I’m going swimming,” Ben said. “Don’t you wish you could go? Or would you rather work?” Tom said, “Work? What do you mean ‘work’?”

“Isn’t that work?” Tom continued painting and answered carelessly, “Maybe it is, and maybe it isn’t. All I know is it suits Tom Sawyer.”

“Do you mean that you enjoy it?”

“I don’t see why I oughtn’t to enjoy it.”

“Does a boy have a chance to paint a fence frequently” said Tom.

Ben stopped munching his apple.

Tom moved his brush back and forth—stepped back to note the effect—added a little paint here and there. Ben watched every move, getting more and more interested, more and more absorbed. After a short time, he said, “Tom, let me whitewash a little.”

Tom seemed to be thinking for a moment before he said, “No, Aunt Polly wants this fence to be perfect. If it was the back fence, maybe you could do it. But this fence beside the street is where everybody can see it. It has to be done right.”

“Oh, come on, let me try. I’ll be careful. Listen, Tom. I’ll give you part of my apple if you let me paint.” “No, Ben, I’m afraid—” “I’ll give you all the apple!”

Tom handed the brush to Ben with unwillingness on his face but alacrity in his heart. While the riverboat worked and sweated in the hot sun, Tom, an artist sat in the shade close by, munching his apple, and planning how he could trick more of the boys.

Before long there were enough boys each of whom came along the street; stopped to laugh but soon begged to be allowed to paint. By the middle of the afternoon, Tom had got many treasures while the fence had had three layers of whitewash on it. If he hadn’t run out of whitewash, he would have owned everything belonging to the boys in the village.

Tom said to himself that the world was not so depressing after all. He had discovered a great law of human action: in order to make a man cover a thing, it is only necessary to make the thing difficult to attain.

The planet is getting greener, and we are responsible. Carbon dioxide generated by human activities is promoting photosynthesis (光合作用) and causing a beneficial greening of the Earth’s surface.

For the first time, researchers claim to have shown that the increase in plant cover is due to this “CO2 fertilisation (肥沃化) effect” rather than other causes. However, it remains unclear whether the effect can reduce any negative effects of global warming, such as the spread of deserts.

To home in on the effect of CO2, Randall Donohue of Australia’s national research institute, the CSIRO in Canberra, monitored vegetation (植被) at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is plenty of warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both.

If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 emissions (排放). Donohue says this lends strong support to the idea that CO2 fertilization drove the greening.

The extra plant growth could have knock-on effects on climate, Donohue says, by increasing rainfall, affecting river flows and changing the likelihood of wildfires. It will also absorb more CO2 from the air, potentially damping down (抑制) global warming but also limiting the CO2 fertilization effect itself.

Donohue cannot yet say to what extent CO2 fertilisation will affect vegetation in the coming decades. But if it proves to be significant, the future may be much greener.

1.According to the author, the increase in plant cover _____.

A. will speed up global warming

B. results from human activities

C. will stop the spread of deserts

D. promotes the CO2 fertilization effect

2.What does the underlined phrase “To home in on” in Para 3 probably mean?

A. To hold back. B. To cut down.

C. To improve. D. To observe.

3. The amount of vegetation in those monitored areas rose with _____.

A. the rise in CO2 emissions B. annual rainfall

C. the temperatures around D. the amount of sunlight

4.What’s the best title of the text?

A. More rainfall, less CO2 emission

B. How to deal with carbon emissions

C. Positive effects of global warming

D. CO2 emission making Earth greener

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

When you’re all comfortable and warm, watching the snowflakes pile up outside, you might wonder, what about the poor animals? No fire. No cocoa. No blankets. 1.

Well, it’s really people who aren’t designed to live in cold climates. 2. Geese have built-in down comforters. Bears have fur coats. Robins just fly south. But look at people. No fur. No feathers. No fair! And not everyone can jet off to Florida when it snows.

3. Mainly, our big brains. Still, it’s taken us a long time to figure out how to cope with cold weather, and along the way we’ve borrowed a few tricks from the animals, too.

When you put on a jacket, you feel warm. Why? Because your jacket traps the heat your body produces. Your body uses the food you eat as fuel to stay warm. 4. Active muscles burn more fuel and produce more heat. That’s why you shiver when you’re cold. By shivering, your body is doing its best to get your muscles moving and warm you up.

5. Even in the coldest weather, your brain needs lots of warm blood. That’s one reason why your feet and hands get cold --- your body is sending heat to your brain. If you put on a hat, you will find that your feet and hands get warmer.

A. How do they stand it?

B. It can no longer trap a layer of warm air.

C. If you run or jump around, you feel even warmer.

D. So what do people have to help beat the cold?

E. Animals have lots of cool ways to survive the winter.

F. That’s because water carries heat away from your skin.

G. The most important part of your body to keep warm is your brain.
