They say that there are some kinds of food people must eat every day. For example, people must eat some green and yellow vegetables. We shouldn’t eat too much meat. People also need to eat some fruits, bread and rice. Of course our bodies need some water and milk. Scientists say people in different countries and different places eat different kinds of food. They cook food in different ways. Different people eat at different times. In one place, people eat once or twice a day. But in another place, people eat three or four times. The scientists say when to eat and how many times to eat are not important. What we eat is the most important thing. Nowadays, the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. It’s bad for people’s health.

Many of these people can not fall asleep. The name of this problem is insomnia (失眠症). Many famous people in history had insomnia. Some of these people have special (特殊的) ideas to make themselves sleep. Benjamin Franklin had four beds. He moved from bed to bed to fall asleep.

You can walk, run, swim, skate or play ball games. Make sure you exercise in the following ways: you like what you are doing; exercise enough but not too much. It’s good to exercise twice a week. Thirty minutes each time is enough. Try all kinds of things until you find one, two or even three sports that are right for you. You can exercise in the gym. There is a lot of equipment there.

Here is some advice to help you protect(保护) yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet(厕所), and after you touch animals, because your hands may carry viruses. Cover your nose and mouth. When someone (某人) sneezes(打喷嚏) or coughs, flu viruses can travel as far as one meter through the air, so you’d better stand a proper distance (距离) while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your ( ) hands. Wear a mask(口罩). Some doctors say that masks can stop the flu as much as 80%, but if you don’t wash your hands often, it’s no use wearing a mask. And it’s necessary to wear the mask in the groups of people. Do sports often. Exercises will help make your body strong enough to resist the virus. ( )56.When did the H7N9 virus hit Shanghai? A．In 2014. B．In 2015. C．In 2012. D. In 2013.
