Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.

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.

Which of the following is in charge of the study?

A. The space agency NASA of the US.

B. The Department of Energy of the US.

C. Ramakrishna Nemani in Missoula.

D. Ranga Myneni in Massachusetts.

What’s the main cause of the plant growth put forward by the study?

A. Growth in population.

B. Regional features.

C. Seasonal variation.

D. Weather conditions

Why do scientists believe that reduced cloud cover has led to the plant growth in the Amazon area?

A. Because plants could take in more sunlight.

B. Because plants could get more rainfall.

C. Because plants could enjoy cooler air.

D. Because plants suffer less from natural disasters.

Which of the following descriptions about the years from 1982 to 1999 is TRUE?

A. It was the warmest on record.

B. Rainfall decreased little by little.

C. World population grew by 25%.

D. Stored carbon increased by 6%.

　　The way people hold to the belief that a fun - filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.

As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably(不可避免的)brought by such things as marriage, raising children, professional achievement, religious commitment (义务), self - improvement.

Ask a bachelor(单身汉)why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.

Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates（解放） time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

1. According to the author, a bachelor resists marriage chiefly because _______ .

A. he finds more fun in dating than in marriage

B. he believes that life will be more cheerful if he remains single

C. he is reluctant to take on family responsibilities

D. he fears it will put an end to all his fun adventure and excitement

2. Raising children, in the author’s opinion is ________ .

A. a rewarding task B. a thankless job

C. a moral duty D. a source of inevitable pain

3. From the last paragraph, we learn that envy sometimes stems from ________

A. hatred　　 B. ignorance C. prejudice　　　D. misunderstanding

4. To understand what true happiness is one must ________ .

A. have as much fun as possible during one’s lifetime

B. be able to distinguish happiness from fun

C. put up with pain under all circumstances

D. make every effort to liberate oneself from pain

5. What is the author trying to tell us?

A. It is important to make commitments

B. One must know how to attain happiness.

C. Happiness often goes hand in hand with pain.

D. It is pain that leads to happiness.

ROME: The legend of Leonardo da Vinci is covered in mystery: How did he die?Are the remains buried in a French castle really those of the master? Was the "Mona Lisa" a self-portrait in disguise (伪装)?

A group of Italian scientists believe the key to solving those puzzles lies with the remains, and they say they are seeking permission to dig up the body to conduct carbon and DNA testing.

If the skull is undamaged, the scientists can go to the heart of a question that has fascinated scholars and the public for centuries: the identity of the "Mona Lisa." Recreating a virtual and then physical reconstruction of Leonardo's face, they can compare it with the smiling face in the painting.

"We don't know what we'll find if the tomb is opened. We could even just find grains and dust," says Giorgio Gruppioni, an anthropologist who is participating in the project. "But if the remains are well kept, they are a biological record of events in a person's life, and sometimes in their death." Silvano Vinceti, the leader of the group, said that he plans to press his case with the French officials in charge of the said burial site at Amboise Castle early next week.

Leonardo moved to France at the invitation of King Francis I, who named him "first painter to the king." He spent the last three years of his life there, and died in 1519 at age 67. The artist's original burial place, the palace church of Saint Florentine, was destroyed during the French Revolution and remains that are believed to be his were eventually reburied in the Saint-Hubert Chapel near the castle.

"The Amboise tomb is a symbolic tomb; it's a big question mark," said Alessandro Vezzosi, the director of a museum dedicated to Leonardo in his hometown of Vinci. Vezzosi said that investigating the tomb could help identify the artist's bones with certainty and solve other questions, such as the cause of his death. He said he asked to open the tomb in 2004 to study the remains, but the Amboise Castle turned him down.

The group of 100 experts involved in the project, called the National Committee for Historical and Artistic Heritage, was created in 2003 with the aim of "solving the great mysteries of the past," said Vinceti, who has written books on art and literature.

Arguably the world's most famous painting, the "Mona Lisa" hangs in the Louvre in Paris, where it drew some 8.5 million visitors last year. Mystery has surrounded the identity of the painting's subject for centuries, with opinions ranging from the wife of a Florentine merchant to Leonardo's own mother.

That Leonardo intended the "Mona Lisa" as a self-portrait in disguise is a possibility that has interested and divided scholars. Theories have existed: Some think that Leonardo's taste for tricks and riddles might have led him to hide his own identity behind that puzzling smile; others have guessed that the painting hid an androgynous lover.

If granted access to the grave site, the Italian experts plan to use a tiny camera and radar to confirm the presence of bones. The scientists would then exhume (挖掘) the remains and attempt to date the bones with carbon testing.

At the heart of the proposed study is the effort to discover whether the remains are actually Leonardo's, including with DNA testing.

Vezzosi questions the DNA comparison, saying he is unaware of any direct descendants (后代) of Leonardo or of tombs that could be attributed with certainty to the artist's close relatives.

Gruppioni said that DNA from the bones could also eventually be compared to DNA found elsewhere. For example, Leonardo is thought to have rubbed colors on the canvas with his thumb, possibly using saliva (唾液), meaning DNA might be found on his paintings.

Even in the absence of DNA testing, other tests could provide useful information, including whether the bones belonged to a man or a woman, and whether the person died young or old.

Even within the committee, experts are divided over the identity of the "Mona Lisa."

Vinceti believes that a tradition of considering the self-portrait to be not just a faithful imitation of one's features but a representation of one's spiritual identity may have resonated (共鸣) with Leonardo.

Vezzosi, the museum director, dismissed as "baseless and senseless" the idea that the "Mona Lisa" could be a self-portrait of Leonardo. He said most researchers believe the woman may have been either a wife of the artist's sponsor, the Florentine nobleman Giuliano de Medici, or Lisa Gherardini, the wife of a rich silk merchant, Francesco del Giocondo. The traditional view is that the name "Mona Lisa" comes from the silk merchant's wife, as well as its Italian name: "La Gioconda."
