    How to Become Fit?
    Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
    During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals, you won’t get enough calories, and then you will feel tired. By the way, calorie is just another word for energy. About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin better and make you healthy.
    Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that teenagers spend at least 30 minutes exercising, five times a week. That is easy to do! You can walk or ride your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability to focus on their study.
    If you follow the suggestions above, you will look and feel much better and become fit.

    Can you imagine a classroom without one thing that has long been considered a necessary part? No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seem to run out of ink at the critical moment.
    A “Paperless classroom” is what more and more schools are trying to realize. Students don’t do any handwriting in this class. Instead, they use hand-sized or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
    Having computers also means that students can use the Web. They can look up information on any subject they’re studying, from maths to social science.
    A high school teacher, Judy Herrel in Florida, US, described how her class used the Web. “Using a book that’s three or four years old is impossible,” she said.
    A paperless classroom is a big step towards reducing the waste of paper.
    “Think about the money and trees we could save with the computers,” she said.
    But, with all this technology, there’s always a risk that the machines will break down. So, in case of a power failure or a technical problem, paper textbooks should still be widely available (可得到的) for these students.
    小题1:The underlined word “critical” in the first paragraph probably has the same meaning as _______.
    A．worryingB．dangerousC．happyD．important
    小题2:You are sure to find __________ in a paperless classroom.
    A．pensB．computersC．test papersD．notebooks
    小题3:According to Judy Herrel, __________.
    A．the Web can talk the students everywhere
    B．the Web can take the place of teachers
    C．the Web is a better tool for information
    D．the Web is for downloading information
    小题4:The paper textbooks should still be widely available because __________.
    A．students won’t have trouble with their pens
    B．computers may break down sometimes
    C．students may not get all information from the Internet
    D．paper textbooks may give students more information

    Liu Xu is a student from a middle school in Guangxi. Once he was riding home when a  robber (盗贼) suddenly jumped out from the roadside. He pulled Liu Xu off his bike and rode away. Liu Xu was scared, but he didn’t run after the robber. He found a telephone and called the police at 110.
    “Safety is the first important in such a situation,” Liu said, remembering what his teacher had told him in his first aid class. “It is not safe to run after an adult who is stronger than you.”
    Liu’s school has compulsory (必修的) first aid education. Students must take the class once a week.
    Teenage safety has become a serious issue recently. According to a survey, about 16,000 teenagers die in accidents in China every year.
    At Liu’s school the first aid classes are to “teach students skills how to protect and save  themselves in emergencies (紧急情况)”. Students there often learn by role-playing in first aid classes. For example, one student performed as a stranger knocking at a door. Another one stood inside the door and asked several questions before letting the “stranger” in. Then they changed roles and did it again. They learned a lot while having fun at role-playing.
    The topics of the first aid classes are regularly updated (适时的). The students have learned skills for surviving in earthquakes. The teacher also taught the students not to go out at night. If someone tried to do bad things to them, they should quickly run into crowed place.

    The bell for class rang. All the students took out their 46 , waiting for the teacher. Our Chinese teacher, Miss Liu, had told us before that we were going to write a composition   47 class.
    A minute passed, and another, 48 the teacher didn't appear. We began to wonder what was the matter with her. Was she ill? Or had she forgotten about the class? 49 could tell. Soon some students began to study other subjects, some students began to talk and even made   50 .
    About ten minutes later, the door opened and Miss Liu 51 came in, smiling. She didn't say sorry to the class. We felt 52 angry. The teacher often told us never to be late for class and said it was 53 manners to be late. She also said that if we were late, we should make an apology (道歉) 54 at once or after class. But now she was late and had kept the whole class waiting for such a long time and didn't even tell us the reason. It was unfair.

    After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
    The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
    A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
    At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
    Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
    People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.
    小题1: What did scientists find in September 2010?
    A．A planet with water. B．A planet similar to the earth.
    C．A planet without life.D．A planet near the earth.
    小题2:According to the article, Gliese 581g ________.
    A．is at the right distance from its starB．moves around the earth
    C．is as far away from us as the moonD．can be reached in about 220 years
    小题3: Paragraph 5 is mainly about ______.
    A．the possibility of living on Gliese 581g
    B．the kinds of chemicals around Gliese 581g
    C．the way of looking for life on Gliese 581g
    D．the aim of studying the radiation on Gliese 581g
    小题4:Which of the following is the best title for the passage above?
    A．Gliese 581g, a Likely Living PlanetB．Gliese 581, a Likely Living Planet
    C．Gliese 581g and Its StarD．Gliese 581g and Radiation
