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.

A year ago, I paid no attention to English idioms, though my teacher emphasized（强调） the importance again and again. But soon, the importance of English idioms was showed in an amusing experience.
One day, I happened to meet an Englishman, on the road, and soon we began to talk． As I was talking about how I was studying English, the foreigner seemed to be astonished, gently shaking his head ,shrugging his shoulders, saying, “You don’t say! You don’t say!” I was puzzled, I thought, perhaps this is not a proper topic．Well, I had better change the topic． So I said to him, “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everybody back home will laugh at me if I leave China without seeing it. It was magnificent（壮丽的，不凡的）.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it. ” Soon I was interrupted（打断） again by his order “You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t request you to do so,” He answered, greatly surprised. I said, “Didn’t you say you don’t say?” Hearing this, the Englishman laughed to tears. He began to explain, “You don’t say actually means really? It is an expression of surprise Perhaps you don’t pay attention to English idioms” Only then did I know I had made a fool of myself.

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, especially their parents, don’t know them as well their friends do. In large families, it is often for brothers and sisters to fight with each other and then they can only go to their friends for advice. It is very important for teenagers to have one good friend or many friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication is very important in children’s growing up, because friends can discuss something difficult to say to their family members.
However, parents often try to choose their children’s friends for them. Some parents may even stop their children from meeting their good friends. The question of “choice” is an interesting one. Have you ever thought of the following questions?
Who choose your friends?
Do you choose your friends or your friends choose you?

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steer them away from fast food shops and bad eating habits.According to the text, what kind of children may eat more unhealthy food?
| A．Those who often take exercise. |
| B．Those who often watch television. |

| B．they are too busy to go out and play |
| C．they can' t choose what to eat |
| D．there are too many fast food shops around |

| A．tell a story | B．provide facts |
| C．give advice | D．compare opinions |
On January 11, 2007, as students sat and listened, a very important guest speaker named Richard, spoke to the students in the lecture hall. He not only showed the potential（潜能）within young adults, but encouraged them to work hard at their lessons.
Richard was a young child when his mother died and his father walked out. He was forced into many different foster homes（寄养家庭）where he felt unhappy. He did not know that his life was taking a turn for the worst.
His uncle, after getting out of prison, got him into drugs and alcohol. His uncle taught him that his place in life was either to be in prison or die trying to be “a man.” His uncle’s teaching almost started affecting him until a very important person came into his life: a teacher. This teacher taught him there is a place in the world for everyone and it isn’t related to drugs.
Richard is now a Harvard University graduate and has a great and loving family. Why? He was taught to have respect not only for others, but for himself.
After the meeting, it was hoped that the students realized within them there is a potential, and within everyone around them, is knowledge. As Richard reminded them, “Knowledge is power.”On January 11, 2007, students listened to a speech made by Richard, who graduated from ________.

An American spacecraft is moving closer to a dwarf planet(矮行星)called Ceres(谷神星). The American space agency's Dawn spacecraft is set to reach the planet-like object in March.
Space agency scientists will then place Dawn in an orbit(轨道) around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it.
Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta(灶神星). Both dwarf planets are in the main belt of asteroids(小行星), a group of large objects, between the planets Mars and Jupiter.
Marc Rayman is the chief engineer and director of the Dawn mission.
Scientists call Vesta and Ceres "protoplanets(行星) ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated(终止)."
Scientists believe Ceres is made of rock, and covered with ice.
The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed.
Carol Raymond is the deputy principal investigator(副首席研究员) of the project. He says Dawn made an unexpected discovery while orbiting Vesta.
"Instead of being bone dry, which we expected, there were patches on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past."
She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too.
If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments.
Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet.Which of the following about spacecraft Dawn is true?
| A．It was sent into space in 2008. |
| B． It is orbiting around the dwarf planet Ceres. |
| C． Its destination is just the dwarf planet Ceres. |
| D． It will gather information about Ceres until early 2016. |
What’s the meaning of the underlined word “patches”?
| A．spots | B．roles | C．sorts | D． kinds |
What do we know about Vesta?
| A． It is in the main belt of asteroids between the planets Mars and Venus. |
| B． It is another dwarf planet which Dawn will explore. |
| C． It is becoming a full-size planet. |
| D． It is made of rock, and covered with ice. |
The passage mainly tells us ______.
| A． Spacecraft , Dawn, is researching Ceres. |
| B． What Spacecraft , Dawn, is. |
| C．NASA Spacecraft, Dawn, is moving closer to a 'Dwarf Planet'. |
| D．How Dwarf Planet research program is carried out. |
