LONDON－Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets (彗星) in the direction of Earth, and its orbit will be changed too. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of U. S. National Aeronautics and Space Administration (NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet－effectively doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈) －by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth--with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped away from Earth”. This would greatly change our planet’s climate.
What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
If the plan is successful, Earth will have a working life of years.
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
What serious problems might the plan cause according to the passage?
| A．The comet might hit Earth and man might lose the Moon. |
| B．Earth might be moved too far away and man might be frozen to death. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
What does the underlined word “compromise” mean?
| A．Provide. | B．Recover |
| C．Share. | D．Endanger. |

Do American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting. But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for 10 to 15 minutes a day, and then other teachers who basically teach it for 60 to 70 minutes a day — which really for handwriting is pretty much.
Many adults remember learning that way — by copying letters over and over again. Today’ s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself. Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.
Handwriting involves two skills. One is legibility, which means forming the letters so they can be read. The other is fluency — writing without having to think about it. Fluency continues to develop up until high school.
But not everyone masters these skills. Teachers commonly report that about one fourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.
But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, which connects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75 percent of students choose to print their essay on the test rather than write in cursive.From Paragraph 1 we can learn ________.
| A．teaching handwriting is a basic requirement in teaching job |
| B．most teachers prefer to teach handwriting |
| C．teachers spend little time in teaching handwriting |
| D．a keyboard has taken the place of the handwriting entirely |
The underlined word “legibility” in Paragraph 3 means ________.
| A．being easy to read | B．being complex |
| C．being unexpected | D．being unreadable |
The best title for the passage is ________.
| A．How to improve handwriting in school |
| B．Right or wrong: the death of handwriting |
| C．Handwriting involves two skills |
| D．Handwriting lessons are on the way out |
The author’ s attitude towards whether still to learn handwriting in school is________.
| A．negative | B．objective |

When Peng Liyuan stepped off the plane in Moscow, the whole world wanted to know who dressed the elegant first lady. The reporter released the secret—Ma Ke.
Peng Liyuan has been wearing Ma Ke’s designs for more than a decade, a fact that was only highlighted recently when she was on her first state visit accompanying her husband President Xi Jinping. The elegant and attractive Peng, formerly a popular singer, has been compared with the US’ first lady Michelle Obama and France’s Carla BruniSarkozy, since stepping off the airplane in Moscow on March 22. Suddenly, everyone was curious to know more about the first lady’s wardrobe.
Even so, Ma prefers a lowkey approach. “If you eat a tasty egg why would you want to see the hen？” she says of all the media attention.
Ma’s relationship with Peng began 10 years ago after a concert in Guangzhou when a reporter told Peng she knew the designer behind the label Exception de Mixmind. Peng asked for an introduction because she was a fan of Ma’s designs and had been wearing them for years.
The two naturally became friends. Ma says:“The painting reflects the painter, and clothes reflect both the designer and the wearer. Someone desires fame and wealth, or love and sympathy; what you have in your heart is reflected in the design. Those who don’t share my philosophy won’t buy my clothes. Peng is a caring person, devoted to charity and environmental protection, which is exactly what I’m doing now.”
However, regardless of the brand, Peng’s support of Chinese labels has surprised millions of Chinese who favor foreign fashion brands.
“Instead she presented a vision of Chinese fashion, desiring to bring Chinese designers to the world stage, ” says a western designer.
The first lady’s doublebreasted coat and her black leather handbag aren’t available at any of Exception’s shops, though Exception’s physical stores do have seen a rising number of visitors.The passage mainly discusses________.
| A．the designer of the first lady Peng Liyuan’s dress, Ma Ke |
| B．the friendship between Peng Liyuan and her designer |
| C．Peng Liyuan’s clothes on her first state visit |
| D．the reactions to Peng Liyuan’s first visit to Moscow |
In the underlined sentence in Paragraph 3 Ma Ke mentioned “an egg and the hen” to show________.
| A．it is hard to explain “Which came first，the egg or the hen？” |
| B．paying such great attention to her was unnecessary |
| C．the outcome was more important than the process |
| D．her dissatisfaction with the media attention on her dress |
What can be inferred from the passage?
| A．First ladies compete with each other whenever they are together. |
| B．Peng’s suits can be bought in Ma Ke’s clothes stores. |
| C．Ma Ke offered to design the first lady’s clothes through her friends. |
| D．Peng had liked Ma’s designs long before she got to know her in the flesh. |
Which of the following statements is NOT true according to the passage?
| A．Peng wears the dress designed by a Chinese designer probably to support Chinese brands |

“Do you like doing things for people?” I asked a friend.
“Yes, most of the time,” she replied.
“Most of the time?”
“Well, I love to do things that are unexpected. I like to do little things most people wouldn't think about doing,” she said.
“But why did you say most of the time?”
“Well, sometimes after doing those little things people take advantage of you. I mean, they expect you to do it again. They ask you to do it. That’s when I don’t like it.”
It was odd that I had this conversation. This just happened to me. I love to do little things. I will pay for a meal card for the people in the office every time we have a meeting there. Not a big thing. It’s a little thing. $5.30 will pay for almost five lunches. Hey, big spender!
I also bought a bag of animal crackers for a friend at work. She was having a tough day and not very happy at all. I drove down to the Wal-Mart and picked up a huge bag for under $2.00. Her smile was worth it.
But one week she said, “Bob, we ran out of crackers. We love them so much.” I didn't want to do it. I smiled and she persisted. I finally admitted, “It’s different when I do it because I want to, but now you are trying to make me go to get them. It’s not the same.” But I bought it for her.
Unfortunately, a big fire in my family took away all the possessions we had. I didn’t know what to do and how to do it. What happened to me then surprised me most. I once had my bike repaired, but the repairman said “no charge” on hearing my sufferings. A stranger called James Kennedy read some pieces I’d written about our sufferings for Slate, the online magazine, and wanted to give us a new house across the lake from New Orleans. I refused but I felt moved. Another poet at the University of Florida also wanted to let his house to me free of charge while he was on holiday. My mates gave us more money for us to rebuild my home. When you do something kind for others, do you always get rewarded? Yes, but not in the way you might expect.What’s the main purpose of the first paragraph?
