Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.
The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.
The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is total amount of carbon stored in land plants.
The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.
Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用). That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.
Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.
All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.

Before World War I we spent our summer holidays in Hungary. I have only the dim(模糊的) memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world and my enthusiasm had led me into varied investigations(调查研究). I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious(清醒的) mind. Suddenly you fancy you see the answer to the riddle, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.
But curiosity, keen(敏锐的) eyes, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the excellent and essential qualities required is self-discipline, a quality I lack. A scientist, up to a certain point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.
小题1:The first paragraph tells us the author ______.
A.was interested in flowers and insects in his childhood |
B.lost his hearing when he was a child |
C.didn’t like his brothers and sisters |
D.was born into a naturalist’s family |
A.he didn’t live very long with them |
B.the family was extremely large |
C.he was too young when he lived with them |
D.he was fully occupied with observing nature |
A.a scientist as well as a naturalist | B.a naturalist but not a scientist |
C.no more than a born naturalist | D.first of all a scientist |
A.has a great deal of trouble doing mental arithmetic |
B.lacks some of the qualities required of a scientist |
C.just reads about other people’s observations and discoveries |
D.comes up with solutions in a most natural way |
Week by week her list grew: I was very thin, I wasn’t a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, then he asked. “Are the things she says true or not? Janet, didn’t you ever wonder what you’re really like ? Well, you now have that girl’s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn’t change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I go to fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it.“That’s just for you,” he said.“You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you’ll find it will be of help to you. Our world is full of people who think they know your duty. Don’t shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”
Daddy’s advice has returned to me at many important moments. In my life, I’ve never had a better piece of advice.
小题1:Which do you think would be the best title for this passage?
A.Not an Enemy, but the Best Friend | B.The Best Advice I’ve Ever Had |
C.My Father | D.My Childhood |

B.She had made a list of my shortcomings and she kept on adding new ones to it so that it was growing longer and longer. |
C.I was having more and more shortcomings as time went on. |
D.Week by week, my shortcomings grew more serious. |
A.Because he believed that what her daughter’s “enemy” said was mostly true. |
B.Because he had been so angry with his daughter’s shortcomings that he wanted to show this by keeping silent for a while. |
C.Because he knew that his daughter would not listen to him at that moment. |
D.Because he wasn’t quite sure which girl was telling the truth. |
A.He told her not to pay any attention to what her“enemy” had said. |
B.He criticized (批评) her and told her to overcome her shortcomings. |
C.He told her to write down all that her“enemy” had said about her and pay attention only to the things that were true. |
D.He refused to take the list and have a look at it. |

Maradona appeared to hit the ball with his hand into the net, and officials allowed the goal to stand despite protests by the English team. Argentina went on to win the 1986 quarterfinal match 2-1 and then win the World Cup.
In his most detailed comments yet, Maradona said he was unable to reach the ball for a header(头球) when he went up against the taller English goalkeeper, Peter Shilton.
After the score, Maradona said he quickly realized the line referee(裁判) had allowed the goal but none of themselves were figuring the goal would be effective.
“I was waiting for my teammates to hug me and no one came,” said Maradona, who was the team captain. “I told them, ‘Come and hug me or the referee isn’t going to allow it.’”
In his 20-year career before retiring in 1997, Maradona starred at Argentinas Juniors and Boca Juniors and in Europe. He also led Argentina league titles(冠军).
In 1991, Maradona failed a drug test and was banned for 15 months. Nine years later, FiFA chose him and Pele as the best players in soccer history.
Recently, he was appointed vice president of Boca Juniors. And with his new TV show, Maradona, 45, has returned to public eyes after years of dealing with drug and health problems.

There was no sign of a call box, nor was there anyone at that early hour I could ask. I had thought I might find a shop selling the Sunday papers or a milkman doing his job, but the town was completely dead.
Then suddenly I found what I was looking for. There was a small post office, and almost hidden from sight in a dark narrow street next to it was the town’s only public call box, which badly needed a coat of paint, I hurried forward but stopped in astonishment when I saw through the dirty glass that there was a man inside. He was very fat, and was wearing a cheap blue plastic raincoat and rubber boots. I could not see his face - he was bending forward over the phone with his back pressed against the glass and didn’t even raise his head at the sound of my coming nearer and nearer. Carefully and surprisedly, I remained standing a few feet away and lit a cigarette to wait my turn. It was when I threw the dead match on the ground that I noticed something bright red trickling from under the call box door.
