We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. “Did Jerry really care when I broke up(分开) with Helen?” “When I got that great job, did Jim, as a friend, really feel good about it?” “And was Paul friendly just because I had a car?” When we look back, these thoughts can make us feel bad. But when we look back, it is too late.

Why do we go wrong with our friends, or our enemies? Sometimes what people say hides their real meanings. And if we do not really listen, we miss the feeling behind the words. When someone tells you, “You’re a lucky dog!” Is he really on your side? If he says, “You’re a lucky guy!” That is being friendly. But “a lucky dog”? There is a bit of envy (嫉妒) in those words. What he may be saying is that he does not think you deserve (应得) your luck.

“Just think of all the things you have to be thankful for” is another phrase（短语） that says one thing and means another. It could mean that the speaker is trying to get you to see your problem. But this phrase contains the thought that your problem is not at all important.

How can you tell the real meaning behind someone’s words? One way is to take a good look at the person talking. Do his words fit the way he looks? Is what he says shown by the tone of voice?  The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save your another mistake.

　　The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.

　　This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi?billion?dollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”

  Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.

　　But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.

  In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.

　　But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said， “This is just wrong.”

5. The passage is about________.

A. a plan turning Mars into a little earth

B. the necessity of changing Mars

C. Mars supporting life

D. finding water in the Mars

6. Which of the following is NOT the reason why some scientists are against the plan?

A. The project would wipe out all the native lifeforms on the Mars.

B. The project will cost too much money and work.

C. We would ruin Mars.

D. We are destroying our own world at an unbelievable speed. 

7. We can infer from the passage that________.

A. water is a crucial factor for life

B. the project will have little effect on the native lifeforms supposed to live on the Mars

C. Monica Grady is in favour of carrying out the little earth project

D. the idea turning Mars into a little earth is nothing but a science fiction

8. Which of the following supports the conclusion of microbes living in the Mars’s soil?

A. Scientists found liquid water in the Mars.

B. Scientists found signs of methane in the Martian atmosphere.

C. Scientists found a lot of good soil on the Mars.

D. Scientists found some creatures living on the Mars.

 The hole in the earth's protective ozone layer（臭氧层）won't repair itself until about two decades later than had been expected, scientists announced.

The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation（紫外线辐射）, helping to make life on Earth possible. For many dacades, ozone was depleted（削减） by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.

Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere（平流层）over the past 27 years.

The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.

Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate（估计）ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.

Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.

2.The improved computer model is believable because _________

3.The underlined word “they” in the fifth paragraph refers to ________

Britain’s seed(种子) bank, the only one in the world aiming to collect all of the planet’s wild plant species, has reached its goal of banking 10 percent by 2010.

The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical(植物的)  gardens—will officially place the 24,200th species on Thursday, a pink, wild banana from China.

More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.                                                                                                                                                            

The seed bank is one of the largest and most diverse(多样的) in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.

The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human eating.

Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.

It is a race against time, Smith said, because in the last ten years alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.

"It is pressing and it is happening now. An area, the size of England, is cleared of primary vegetation（植被）every year." Smith said.

Because most of the world's food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.

For Kew's next goal—to collect a quarter of wild varieties（种类）by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.

Bobby Moresco grew up in New York’s Hell’s Kitchen, a poor working-class neighborhood on Manhattan’s West Side. But Hell’s Kitchen lies right next door to Broadway, and the bright lights attracted Bobby from the time he was a teen. Being stage-struck was hardly what a street kid could admit to his partners. Fearing their making fun of him, he told no one, not even his girlfriend, when he started taking acting lessons at age 17. If you were a kid from the neighborhood, you became a cop, construction worker, longshoreman or criminal. Not an actor.

   Moresco struggled to make that long walk a few blocks east. He studied acting, turned out for all the cattle calls (试戏通告)-- and during the decade of the 1970s made a total of $2,000. “I wasn’t a good actor, but I had a driving need to do something different with my life,” he says.

He moved to Hollywood, where he drove a cab and worked as a waiter. “ My father said, 'Stop this craziness and get a job; you have a wife and daughter.' ”But Moresco kept working at his chosen career.

   Then in 1983 his younger brother Thomas was murdered in a killing. Moresco moved back to his old neighborhood and started writing as a way to explore the pain of Hell’s Kitchen. Half-Deserted Streets, based on his brother’s killing, opened at a small Off-Broadway theater in 1988. A Hollywood producer saw it and asked him to work on a screenplay.

    His reputation grew, and he got enough assignments to move back to Hollywood. By 2003, he was again out of work and out of cash when he got a call from Paul Haggis, a director who had befriended him. Haggis wanted help writing a film about the country after September 11. The two worked on the writing Crash, but every studio in town turned it down. They kept trying. Studio executives, however, thought no one wanted to see hard lives in modern America.

Crash slipped into the theaters in May 2005, and quietly became both a hit and a critical success. It was nominated for six Academy Awards and won three -- Best Picture, Best Film Editing and Best Writing (Original Screenplay) by Paul Haggis and the kid from Hell’s Kitchen.

   At age 54, Bobby Moresco became an overnight success. “If you have something you want to do in life, don’t think about the problems,” he says, “think about other ways to get it done.”
