Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.
Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees) . Trees soak up carbon dioxide, one of the greenhouse gases, from the air.
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that is disappearing because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.
Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (聯(lián)邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do.
Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.

Be careful! Some people may use the truth to deceive. When someone tells you something that is true, but misses important information that should be included, he can create a false impression(印象).
For example, someone might say, "I just won 100 dollars on the lottery(彩票). It was great. I took that ticket back to the store and they gave me 100 dollars!"
This man is a winner, right? Maybe, maybe not. We then discover that he paid 200 dollars for 200 tickets, and only one ticket won. He's really a big loser.
He didn't say anything that was false, but he didn't give the other important information. That's called a half-truth. Half-truths are not lies, but in fact they are dishonest.
Advertisements sometimes use half-truths. It's against the law to lie in advertisements, so they try to deceive with the truth. An advertisement might say, "Nine-tenths of doctors believe that Fancy Pills will be good to cancer. " It doesn't tell you that they only asked ten doctors and nine of them work for the Fancy Company.
This kind of thing happens too often. It's a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
小題1:What does the underlined word "deceive" mean in Chinese?
A.坦白 B.引人注意 C.獲勝 D.欺騙

It is reported by Chinese Xinhua News that students waste more food than the national average. So the campaign on school food waste is getting popular across the country. The move is part of a national campaign started by students at different schools.
At East China University of Science, students who finish their food in the school dining hall get a special card when they return their plates after meals. Students can collect cards and exchange them for small gifts, such as books, schoolbags, magazines and umbrellas. “It’s been such a surprise,” said Liang Zhaoyun, 19, a student in Shanghai. “It has given us one more motivation to eat up our food.”
“The purpose of the campaign is not only to encourage students to finish their food. We hope it can also teach students to choose a more environment-friendly and healthy lifestyle,” said Tao Siliang from University of Traditional Chinese Medicine.
Other schools also pay attention to the quantity of food. At Nanjing No.9 Middle School, rice is divided into three different-sized bowls that students can choose from according to their own need. “It’s great because I can try different dishes at half price and don’t waste so much food,” said Fan Peng, 15, a student from this middle school.
What if you really can’t finish all your food? At Changchun Normal College, they provide a take-away service. “If you can’t finish all your food, you can get a box to take the left food home. Even if you feed the cat, it’s not wasted,” said Zhou Zeyong, a student who learns Chinese education.
“I’m happy that we’ve cut down waste since joining the school ‘eat-up’ meeting. But some food is poorly cooked, meaning that students are not willing to finish it all. Some schools have taken note of this. So if we hope students try to waste less food, we should also improve the service and keep an eye on the meal quality on weekdays at school. If not, you can’t complain students for throwing away much food,” said Wang Guangji, the head-teacher of Beijing No. 29 Middle School.
小題1:Why did we start the campaign on food waste at schools?  Because __________.
A.food waste at school is very serious.
B.students should not eat more food
C.it is students’ duty to eat less food
D.it’s easy for schools to start a campaign
小題2:Who can get some gifts at East China University of Science?
A.Students who buy some special cards.
B.Students who eat up all the food.
C.Students who do some dishes.
D.Students who spend money on gifts.
小題3:What’s Tao Siliang’s idea in the passage?
A.Getting small gifts is surprising.
B.Different-sized bowls make students happy.
C.Students should take a healthy lifestyle.
D.It’s a good idea to feed a cat with left food.
小題4:Which of the followings is true according to the passage?
A.The campaign is only to encourage students to eat up food.
B.We try to think up many good ways to help clear plates.
C.We will make notes if students waste much food again.
D.We shouldn’t complain students for throwing away food

Childhood is a time of fun and games. Many people still remember when they were young, they often played games like hide-and-seek and chess. Playing teaches children how to get with others, and it also helps to exercise the mind and body. However, children today spend most of their time in front of the computer, playing video games.
A recent survey found that in the US. Children between 8 and 12 spend at least 13 hours a week playing video games or "gaming". Boys of this age spend even more time, almost 16 hours a week. Although some people will say that gaming is helpful, it brings many problems as well.
One big problem is that kids who spend most of their time on games might have difficulty communicating with real people. They might have trouble sharing and resolving (解決) problems because they do not practice these skills when sitting alone at a computer.
Another problem is about health. Game players usually sit for hours without doing any exercise. And they might not eat healthily. As a result, they might be out of shape.
Next, game players might have trouble with their lessons. Many of them spend more time playing games than working on their homework. In the end, they fail in the exams.   
Finally, it is always possible that the gamers become addicted. Some people play four or five hours a day or even all day. This happened to a 28 - year - old Korean man. He spent about 50 hours playing an online game without sleeping or eating well. He died while gaming!
This is one example of the dangers of video gaming. It tells us that video gaming, like everything else, should not be done too much. A few hours a week should not hurt, but several hours a day just might be dangerous to your health.
小題1:Children of 8 to 12 in the US spend at least _________ hours a week playing video games.

It will not be possible to do it if they don’t have computer classes. Most of the homes have personal computers now and most children are already aware of the basics before they join school.

Tired of bad handwriting, Richie decided to perfect his penmanship (書法) last January. Though the year progressed, his writing didn’t. “My penmanship just got worse,” he says. “I get tired of trying to write neatly.”
Like Richie, many teenagers make resolutions in the New Year. More than half of Americans say they make a New Year’s resolution – but only one-third of them keep to it, reports the University of North Carolina, US.
Demanding (追求) perfection  stops people working on their resolutions, says Chicago life coach Alison Miller.
Resolutions sometimes can be unrealistic (不現(xiàn)實(shí)).. Going for a goal  that’s too hard to achieve can leave a person feeling sad. “Saying ‘I’m going to look like a super-model’ is going to make you unhappy,” she says.
Sure, it’s a great idea to aim for improvement, but not all resolutions are helpful. The difference between good and bad resolutions is whether you expect too much from yourself, Miller says. For example, it’s OK to say, “I’m going to eat fewer French fries,” but striving (力爭(zhēng))  for a perfect body isn’t reasonable.
Timing can also damage a resolution. Kevin M., 16, says he doesn't set resolutions because 12 months is unrealistic. “It’s too long and you start putting off keeping your resolution during summer,” he says.
He’s considering a career in music, but says school is his main focus. Knowing how hard he has to work, he says he’ll “be lucky to get 30 minutes a day” of practice. But a bit is better than nothing, and making reminders can help you make progress. Miller says teenagers should write down their goals and say to themselves, “What can I do today to make my goal a reality?”
“It’s just small steps along the way. It’s not about doing it all at once,” Miller says.
小題1:What’s the writer’s purpose by talking Richie in the first paragraph?
A.To advise people to keep their New Year’s resolutions.
B.To show that some people fail to keep their New Year’s resolutions.
C.To tell readers why Richie isn’t a good hand writer.
D.To show why New Year’s resolutions are important.
小題2:Many Americans stop working on their New Year’s resolutions because ______.
A.they think it is silly to make resolutions
B.they find keeping resolutions is boring
C.the time of keeping resolutions is too short
D.their choice of resolution turns out to be unrealistic
小題3:Which of the following statements would Miller probably agree with?
A.Teenagers should set themselves perfect goals.
B.To achieve your goals, you needn’t write them down.
C.People should try to realize their goals step by step.
D.A good resolution helps people realize their possibility.
