【題目】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() 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.

1Sea bacteria are _______ for people.

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

2Why 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.

3Which 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.

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

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

5Which of the following food has the enzyme?

A. Restaurant sushi. B. Restaurant seaweed.

C. Uncooked seaweed. D. Seaweed soup.
