Do you like to eat sushi(壽司)? Many people are afraid to eat it, because they think the bacteria(細(xì)菌) in it might make them sick. However, a new study shows that sea bacteria are good for people. The study finds that a special enzyme(酶) from sea bacteria is helpful to humans. It helps people to get more energy from food.

To people’s surprise, the enzyme is present only in the Japanese. The Japanese traditionally like to eat food rich in seaweed(海藻). And the seaweed is rich in this kind of enzyme.

However, the enzyme isn’t present in all the Japanese. During the study, just 5 out of 14 Japanese had the enzyme. All the Americans studied didn’t have the enzyme.

“The number is small,” said researcher Mirjam Czjzek. “But we can say that this enzyme is present only in the Japanese and not in the North Americans.”

Then some people think that maybe other people are able to get the enzyme if they eat a lot of seaweed. The study suggests that they collect uncooked seaweed to make their sushi.

Restaurant sushi is often cooked, which will destroy the enzyme. So, if you want to get that enzyme, you can travel to Japan to have a taste of the real sushi.

1. Sea bacteria are _______ for people.

A. helpful B. harmful C. important D. necessary

2. Why do the Japanese have the special enzyme?

A. Because they eat a lot of seaweed.

B. Because they were born with such an enzyme.

C. Because they get more energy from food.

D. Because they like to eat food full of bacteria.

3.Which of the following is FALSE?

A. The Japanese have a diet rich in seaweed.

B. All the Japanese studied have the special enzyme.

C. All the North Americans studied don’t have the enzyme.

D. The enzyme helps people to get more energy.

4.According to the study, about _______ of Japanese have the enzyme.

A. 5% B. 14% C. 35% D. 60%

5.Which of the following food has the enzyme?

A. Restaurant sushi. B. Restaurant seaweed.

C. Uncooked seaweed. D. Seaweed soup.

閱讀下面的短文，并根據(jù)文章后的要求答題。（請(qǐng)注意問(wèn)題后的詞數(shù)要求）

Recently using a mobile phone has become a fashion. Do you often send text messages (短信) to your friends or family? If you keep sending text messages over and over again, there may be something wrong with your fingers. Everybody using the mobile phones should be careful. If you don’t, you may get injured one day.

Text messaging or texting is becoming popular. But scientists have found out that texting can give us problems with fingers. Too much texting can make your fingers uncomfortable. When we press small buttons over and over again, we may have a disease called RSI. RSI is short for Repetitive Strain Injury (重復(fù)性力損傷).

Harriet Wilson is a doctor. She has many patients with RSI. She says we should check how much time we are spending in typing text messages. _________ we spend more than 10 to 15 minutes every day, we could have such problems in the future.

Mobile phones are getting smaller and smaller. And the buttons are getting closer together. Texting with a smaller phone is worse than using a larger phone with bigger buttons. So it’s a good idea to use a larger phone. If you use a computer keyboard and play video games for long, you may have the same problem. More and more people can find themselves with RSI.

1. What’s the result of keeping sending text messages over and over again?(no more than 8 words)

2. Translate the underlined English sentence into Chinese.

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources (資源)， we are short of others， for example， fresh water. It is reported that we will have no coal or oil to use in 100 years. So if we go on wasting our resources， what can we use in the future and where can we move? Think about it. (3) I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life， we can do many things to prevent (阻止) waste from happening， for example， turn off the water taps when we finish washing， turn off the lights when we leave the classroom， try not to order more food than we need， and so on. Little by little， everything will be changed. (4) Waste can be stopped one day， if we do our best.

A story happened when the telegraph（電報(bào)）was the fastest method of long-distance communication. One day, a young man went to an interview for a job as a Morse code operator（莫爾斯電碼報(bào)務(wù)員）.

Answering the ad in the newspaper, he went to the office address. When he arrived, he walked into a large, busy office filled with noise, including the sound of the telegraph. An office worker asked him to wait until he was called to go into the inner office. Seven other people were already in the waiting area for the interview. The young man sat down and waited with them. After a few minutes, the young man stood up, crossed the room to the door of the inner office, and walked right in. Naturally the other people wondered what was going on. They were sure that the young man made a mistake and would be refused.

A few minutes later, however, the boss came out of the inner office with the young man and said to the other people,“Gentlemen,thank you very much for coming, but the young man has got the job.”

The other people were surprised, and one of them said, “Wait a minute. I don’t understand. He was the last to come in, and we never even got a chance to be interviewed. Yet he got the job. That’s not fair!”

The boss said, “I’m sorry, but all the time you’ve been sitting here, the telegraph has been sending out the following message in Mores code: ‘If you understand this message, then come right in. The job is yours.’ None of you heard it or understood it. This young man did. The job is this.”
