An astronomer is making a case for launching pop singer Justin Bieber into suborbital(亚轨道的)space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.
It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”
Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.
None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.
Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.
A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling(充满)with cameras both inside and out, to give the public dramatic views of every mission.
Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.Why may Justin Bieber be sent into suborbital space?

Teenagers are often a difficult group. With all those hormones(荷尔蒙) flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food are likely to be happier than other teens.
The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are.
Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food.
Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining(克制) from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too.What can we learn from the text?
| A.Not smoking or drinking guarantees happiness. |
| B.Teens with flooding hormones can not be happy. |
| C.Playing sports can decrease teen’s unhappiness. |
| D.Unhappiness can certainly result in smoking and drinking. |
Which of the following might help teens quit anxiety?

| B.Taking exercise. |
| C.Eating junk food. |
| D.Going on a diet. |
Which can be the best title for the text?
| A.Ways to treat anxiety and depression. |
| B.Exercise and teenagers’ health. |
| C.Teenagers shouldn’t drink or smoke. |
| D.Teenagers’ lifestyle and their happiness. |
The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.
The fire started on Sunday morning in the house of the King's baker in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.
Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect, wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them was new St Paul's.
The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.It seems that the writer of the text was most sorry for the fact that ______.

Two students started quarreling at school. One student shouted dirty words at the other, and a fight began. What can be done to stop fights like this at school? In some schools, the disputants sit down with peer mediators(同龄调解者). Peer mediators are students with special training in this kind of problems.
Peer mediators help the disputants to talk in a friendly way. Here are some of the ways they use:
1) Put what you think clearly but don’t say anything to hurt the other. Begin with “I feel…” instead of “You always…”
2) Listen carefully to what the other person is saying. Don’t stop the other person’s words.
3) Keep looking at the other person’s eyes when he or she talks.
4) Try to see the other person’s side of the problem.
5) Never put anyone down. Saying things like “You are foolish” makes the talk difficult.
6) Try to find a result that makes both people happy.
Peer mediators never decide the result or the winner. They don’t decide who is right and who is wrong. Instead, they help the two students to find their own “win-win” result.The underlined word “disputants” refers to the students ________.

In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes(性别) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally(通常) see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神经) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(创造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller nerves than the two sides of a woman’s brain are.Which of the following is best to outline(概括) the article?
| A.Research on the brain. |
| B.Differences between men and women |

After my dad died on Aug.30, 2001, my mother made sure we marked each anniversary. At first, my brothers and sister and I would travel hours to get home, but eventually we got to the point where just one or two of us would make it back to go to Mass with her and spend the day together.
The great love of her life, the man who broke up with her right before her college graduation, only to return two years later claiming he'd traveled the world and hadn't found anyone to compare with her, remained a daily presence in her life.She spoke about him so often and kept his memory so alive that people were sometimes surprised to learn that he was gone. She took over the garden where he'd planted and made it on her own.
When the 10th anniversary of his death approached,my mom began talking about it and planning for it weeks in advance. The date on her kitchen calendar was circled and marked R.I.P. (Rest in Peace). Of course she wanted all of us there and settled the date for our coming back.
On Monday—the day before the anniversary—she went to Mass and walked downtown for lunch with friends, and later told my sister on the phone that she felt Dad still so close that as she was walking back home, she heard someone yell and thought, “Oh, there's Dick.”
That evening she went out to water flowers, just as my father, 10 years before, had gone out to the garden to pick vegetables before he died. A neighbor heard the tin watering can strike the ground as she fell and hit her head. My mother died within hours, on Aug. 30, 2011, the 10th anniversary.
