举一反三
In China, I had English classes five times a week since Grade Five. But I didn’t know textbook English could be so different from everyday English until I came to Hotchkiss School, Connecticut. When I first studied English, I was told to say “I’m fine.” when people say “How are you?” But in the USA, I found that people say “I’m good.” or “I’m tired.”
One day, someone greeted （问候） me with “What’s up?” It made me confused. I thought for a moment and then smiled because I didn’t know what to say.
Since then, I have learnt more and more differences between Chinese and American cultures. To my surprise, American girls spend a lot of time in the burning sun getting a tan (晒黑的肤色). In China, girls try every possible way to keep their skin white.
American students are hard-working like Chinese students. In China, schoolwork is almost everything, so we study hard and that’s it. But here, a “good” student not only gets good grades, but also does a lot for the public. That is to say, they get lots of knowledge at school and learn many life skills from social （社会的） work.
小题1:In China, Wang Jun had _______ English classes every week.
| A．five | B．four | C．three | D．two |
A. it was really important to learn English well
B. English he learnt in China was helpful to him
C. American students were more hard-working than Chinese students
D. textbook English was different from everyday English
小题3:What does the underlined word “confused” mean in Chinese?
| A．困惑的 | B．滑稽的 | C．紧张的 | D．伤心的 |
| A．they work hard at school | B．they try to keep their skin white |
| C．they hope to get a tan | D．they do lots of social work |
| A．My wonderful travel in the USA | B．After-school activities in American schools |
| C．What American students learn at school | D．My study experience in the USA |
The Chinese Medical Doctor Association released the 2013 China Sleep Quality Index (指数) on March 19 to mark World Sleep Day – March 21.
According to the index, nearly a quarter of Chinese people don’t sleep well. Half said that they feel tired after getting up and 15 percent people have trouble falling asleep.
Ye Jingying, a sleep expert at Beijing Tongren Hospital, says: “If people often wake up during the night, or always feel weak and tired in the day, they should pay attention to their sleep pattern (模式).”
Many people play with their cell phones or iPads before sleeping. The report said that this is one of the main reasons for bad sleep. Other reasons include stress and bad moods.
How to sleep well? Above all, get enough sleep. Seven to nine hours of sleep every night is perfect for an adult, and eight to nine hours is best for a teenager.
Forming good sleep habits is important. The report suggested that people need to keep away from digital devices (数码产品) for at least an hour before sleep. The lights keep their brains excited for a long while. Other suggestions include: try to go to sleep and wake up at the same time every day, even on weekends and during holidays, and do the same relaxing things before bed each night, like listening to soft music.
小题1:From Paragraph 1, which of the following is NOT true?
| A．The longer you sleep, the better. |
| B．Many Chinese people don’t sleep well. |
| C．Many Chinese people don’t care about sleep. |

Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.
In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.
In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.
As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.

Land pollution is caused by solid waste, such as cans, bottles and some plastic things which aren’t broken down quickly. It makes the environment look very bad. However, air pollution is more serious than land pollution. It is much worse in cities and towns because of the fumes(废气) from traffic and the waste from human activities. When people drive their cars, fumes which are most made up of CO2, NO2 and SO2 are given off. After the gases get into the air, they may mix with clouds. Then they will become some harmful chemicals (化合物) falling on the ground with rain. It is one of the reasons for soil erosion (土壤侵蚀) which is one example of water pollution.
Various kinds of pollution will cause many health problems. People have realized they must change this serious situation. There are many ways to control pollution. To develop alternative energy is very popular in many countries. China, for example, has made up its mind to be a leader in this field. It is trying hard to make full use of energy from the sun and wind. It has paid plenty of money to make electric cars and trains instead of traditional traffic. We should also take action to make our environment cleaner every day. Take cloth bags while going shopping and drive cars less. We have only one earth. We must take steps now to help protect our environment for the future wherever we are.
