In the modern world, pressure is a serious problem. Today, most student are under too much pressure. Some students can’t get on well with their classmates. While others may worry about their tests. Even they can't get enough and good sleep. I’m always under pressure, too.
How can we solve the pressure problems? Here are my suggestions.
The first, tell your pressure to someone. I think a conversation with parents or teachers is necessary to solve the problem. We can talk our problems with our teachers or parents. My parents want me to be the top student in class. So they send me to all kinds of training classes at weekends. I feel tired and unhappy. Last Monday evening, I had a talk with my mother. I told her I was not lazy. I really felt tired. I needed time to relax. My mother agreed with me at last.
The second, learn to relax yourself. I think the most important way to relieve us from our pressure is to learn to relax ourselves. In order to relax ourselves, we can turn to some of our hobbies and interests. Different students have different ways. For example, we can listen to music, watch TV, or read some books. But for me I often exercise. I enjoy it. I think taking exercise can not only rest our brains and eyes but also help build our bodies. I think sports are really helpful to both my health and my study. We can also go for a trip. We can visit somewhere beautiful and peaceful to relax.

Maybe most people know that there is water pollution, air pollution and noise pollution around us, but few people know that there is another kind of pollution—light pollution. In fact, it can be everywhere, depending on the time of the day.
Light pollution is the result of the wasted energy. Instead of providing light for people on the earth, most bright light shines into the sky, because people don’t design lights very well. At the same time, lights are brighter than necessary. All these cause light pollution. Stars in the night sky always provide everyone with wonderful sights(景色), but light pollution prevents them from being seen.
Some scientists say that light pollution can also bring some health problems to people, especially to kids. So it’s the high time for us to do something useful to stop light pollution.
根据短文内容，判断下列句子的正(T)误(F)。Light pollution isn’t serious enough for us to stop it now.
All the people know light pollution well today.
Most light shines into the sky instead of providing light for people.

Light pollution doesn’t do harm to people’s health.
If you lose 12 times in a row (连续地), will you just give up? Dale Carnegie, a pioneer in public speaking and self-development, kept trying. And he became famous by showing people how to be successful.
Carnegie was born into a poor family in the United States. The boy didn’t see a train until he was 12 years old. In his teens, he had to get up at 3 am every day to milk the cows for his family.
When Carnegie first entered college, he felt upset because of his ragged (破旧的) clothes and ordinary(平凡的) looks. His mother encouraged him, “Why not try to be better in other things instead of just dress and good looks?”
Carnegie tried to be more active in college. He joined the debate (辩论) team. But one after another, he lost 12 competitions. The young man was very disappointed with himself. He said later that he thought of killing himself after failing so many times. But soon Carnegie was seen practicing public speaking on the riverside. His hard work paid off at last. In 1906, Carnegie won a famous speech contest and became well-known. “Believe that you will succeed, and you will,” he said.
In order to share his success, Carnegie opened schools and wrote books. His best-sellers(畅销书) include How to Win Friends and Influence People and How to Stop Worrying and Start Living. More than 50 million copies of his books have been translated in 38 languages. They are still helping people on the road to success.What did Carnegie have to do every morning in his teens?

What did Carnegie do to be more active in college?
What did Carnegie do after failing so many times?

Bicycle sharing systems are also known as yellow bicycle programs, white bicycle programs, public bikes, or free bikes. They are increasingly popular in Europe now. Paris has the world’s largest urban (城市的) cycle rental system.
This is a bike rental station in Paris. The worker is showing how to use a new self-service bike. They say that Paris will become “a green capital of bikes” and they plan to park 20,000 bicycles at 1,600 stations. Paris created this plan to improve the city traffic environment and reduce the waste gas displacement (废弃排气量).
At a rental station, you only have to put your credit card into the machine to rent a bike. It provides French, German, English and Chinese services. If you ride the bike for only 30 minutes to relax, you needn’t pay for it. A two-hour bike rent only costs you 4 euros.
These stations work for 24 hours every day, so a bike is rented for 10 to 14 times a day. In this way there are 200,000 people using bikes a day,
In the past few years, Paris has encouraged its people to ride bikes, but something unhappy has happened now and then. Some people break the traffic rules during rush hours. Some park their bikes everywhere. So how to park bikes is a problem that Paris will face. But this project is still a helpful way to improve its traffic environment. Don’t you think so?Bicycle rental system can help Paris become a ________.
| A．fashion capital | B．sleepy city |
| C．polite city | D．green capital of bikes |
Paris built many rental systems to_______.
| A．relax travelers | B．improve the environment |
| C．reduce traffic accidents | D．get money |
The machine at a bicycle rental system offers _______language services.
| A．two | B．three | C．four | D．five |
_______ people use bikes a day
| A．1,600 | B．20,000 | C．24,000 | D．200,000 |
From the passage we can infer that the author__________.
| A．thinks bicycle rental systems are great |
| B．doesn’t agree the idea of bicycle rental system |
| C．thinks Paris is a bicycle capital |
| D．thinks bikes are better than cars |
Sports can help you keep fit and close to nature. However, whether you are on the mountains, in the waves, or on the grassland, you should realize that sport you choose might have great influence on the environment.
Some sports are resource—hungry. Golf, as you may know, eats up not only large areas of countryside, but also lots of water. Besides, huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental changes. For example, in the dry places of Portugal and Spain, golf is often held responsible for (为…承担责任) serious water shortage(短缺) in some local areas.
There are many environment—friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes, and you don’t have to worry about resources and your purse. Simple and free, power walking can also help you stay healthy. If you walk regularly, it will be good for your heart. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and keep thin.
Whatever sport you take up, you can make it greener by using environment—friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms.” They are better replacements(替代) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership(会员身份). And best of all, it’s free.Which of following does the author most probably support according to the passage?
