B

Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution：less water, less hydropower and less wind energy.

Scientists studied the effects of aerosol（浮质）pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.

Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense（凝结）onto a particle to form a raindrop. And if the cloud of fine droplets（小滴）moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.

Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate（微粒的）pollution over the oceans.

Good advice is like medicine for the soul. What kind of   36  have you recently received? Who do you go to get advice? Do you have a mentor（顾问）? A mentor is a   37  adviser.

At the top of a three-storey brick house Sue and Johnsy had their studio. In November a cold, unseen stranger, whom the doctors called Pneumonia(肺炎), touched one here and there with its icy fingers. Johnsy was struck down, and she lay, hardly moving, on her bed looking through the window at the blank side of the next brick house.

One morning the busy doctor invited Sue into the hallway(走廊).

“She has one chance in ten,” he said, “And that chance is for her to want to live. She has made up her mind that she’s not going to get well. I will do all that I can. But whenever my patient begins to count the carriages in her funeral procession(队列), I subtract 50 percent from her chance to live.”

After the doctor had gone, Sue went into the workroom and cried. Then she came into Johnsy’s room with her drawing board, whistling.

Johnsy lay hardly moving with her face toward the window. Sue stopped whistling, thinking she was asleep.

She arranged her board and began a drawing. As Sue was sketching, she heard a low sound. She went quickly to the bedside.

Johnsy’s eyes were open wide. She was looking out the window and counting backward.

“Twelve,” she said, and a little later “eleven”; and then “ten”, and “nine”; and then “eight” and “seven”, almost together.

Sue looked out the window. What was there to count? There was only the blank side of the brick house twenty feet away. An old ivy vine(常春藤) climbed halfway up the brick wall. Its branches clung(紧紧缠着), almost bare, to the bricks.

“What is it, dear?” asked Sue.

“Six,” said Johnsy, in almost a whisper. “They’re falling faster now. Three days ago there were almost a hundred. There goes another one. There are only five left now”.

 “Five what, dear? Tell me.”

 “Leaves. On the ivy vine. When the last one falls, I must go, too. Didn’t the doctor tell you?”

 “Oh, I never heard of such nonsense,” said Sue. “What have old ivy vine leaves to do with your getting well? Why, the doctor told me this morning that your chances for getting well real soon were ten to one! Try to take some soup now.”

 “There goes another. No, I don’t want any soup. I want to see the last one fall before it gets dark. Then I’ll go , too.”

 “Johnsy, dear,” said Sue, bending over her, “will you promise me to keep your eyes closed, and not look out the window until I’m done working? I need the light or I would draw the shade down.”

“Tell me as soon as you have finished,” said Johnsy, closing her eyes, “because I want to see the last one fall. I’m tired of waiting. I want to turn loose my hold on everything and go sailing down, down, just like one of those poor, tired leaves.”

1.By saying “Pneumonia touched one here and there” (in the first paragraph), the author means that _________.

A.some people were affected by the illnesses of others

B.pneumonia caused damage to the ivy vine

C.two people became ill

D.many people came down with the illness

2. How did Johnsy feel about the situation during the passage?

A. confident      B. hopeless        C. tired           D. curious

3.We can learn from the passage that _____________.

A.Sue came into the room whistling perhaps because she thought Johnsy might like the music.

B.Johnsy’s life was compared to the carriages in a funeral procession

C.Sue told a lie to Johnsy about the doctor’s words

D.Johnsy wanted to know about the falling ivy leaves to meet her own curiosity

4.The underlined word “subtract” in the third paragraph probably means “________”.

A. reduce      B. hope        C. add          D. doubt

5.The passage is probably taken out of ______________.

A. a newspaper    B. a novel

Rubber ducks are being used to help scientists understand global warming and melting glaciers. NASA researchers have  21   90 ducks into holes in Greenland's fastest moving glacier, the Jakobshavn Glacier between Greenland and Canada. The   22   have each been marked with the words "science experiment" along with an e-mail address. If they are found scientists will be able to  23   how the water moves through the ice and provide information about the   24   of glaciers. Scientists are still   25   about why glaciers speed up in summer and head towards the sea. One theory is that as the summer sun melts ice on top of the glacier's surface, the water moves to the bottom of the glacier, where it helps to   26   the movement of ice toward the coast. The Jakobshavn Glacier is believed to be the   27   of the iceberg that sank the Titanic in 1912. Robert Jones, the experiment organizer, said none of the ducks had been   28   yet. "We haven't heard back but it may take some time until somebody actually finds it and decides to send us a/an   29   that they have found it," he said. "These are places that are   30   so there aren't people walking around."
