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. 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.

Evolution has changed our bodies and faces over thousands of years, and it's still happening. Here's how experts predict what people will be like in 1,000 years. We'll be about 1.83~2.13 metres tall because of improved nutrition and medical science. Our arms and fingers will get longer to reduce the need to reach too far. We'll have smaller brains, maybe because computers will help us memorize and think most of the things. There will be larger eyes and smaller mouths. And there may be fewer teeth as softer food needs less chewing and biting. We could even get our nutrition from liquids or pills in the future. We can expect other great changes too. Everyone will have the same shape of noses. That's because climate will have less influence on noses with the help of air conditioning and central heating. Besides, we will have more wrinkles as a result of looking at our electronic devices. We also may end up with saggy necks because extra sun will cause loose skin. And there will be darker skin as people move around the planet and races mix. ,. How will we usually memorize and think? A) By robots. B) By larger brains. C) By computers. D) By smarter brains.
