Do you like to eat sushi ? Many people are afraid to eat it, because they think the bacteria 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 . 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. Sea bacteria are _ for people. A) helpful B) harmful C) important D) necessary

Question: My parents divorced when I was 8 years old. Their marriage was a mistake of World War II. And about 50 years ago, I was the only child I knew who didn't have a father at home on Father's Day. Divorce was very uncommon back then. So when my friends were in town shopping for presents for their fathers, I decided since my mother was both Mother and Father, no one else was like her, who better deserved(be worth) a present on Father's Day than her? I bought her a little set of tools, just a few things, hammer, pliers and screwdriver and a box to put all these things in. I got some ideas from my grandfather and named it Mother's Tool Box. She was excited, more at the thought of being cared for on Father's Day than of the present. She always said she liked her Father's Day memories better than the Mother's Day ones. It made her feel special -- and she was. I have noticed in the past few years, greeting cards are even made for "Mother on Father's Day". Ever since then, my mother has got cards on Father's Day. By the way, she knew just how to use those tools and others she had ever used over the years. What did the writer decide to do when he saw friends shopping for Father's Day presents? A) Go shopping with his friends. B) Buy a present for his mother. C) Help his mother. D) Ask his grandfather for help.
