Spring is an inviting season for outdoor activities. But be careful—the warm weather is also a hotbed for viruses(病毒) and disease.  
This March, the influenza(流行性感冒) A(H7N9) virus hit Shanghai, Anhui, Jiangsu and Zhejiang. It was reported that by April 11 at least 35 people had been infected (被感染的) with the H7N9 virus, and nine of them had died.
The influenza A (H7N9) virus is one type of influenza A H7 viruses. Influenza A H7 viruses normally spread among birds.
This is the first time human infections with H7N9 viruses have been reported in China. Earlier reports were about H5N1 and H1N1.
All the three viruses are influenza A viruses but they are not the same. H7N9 and H5N1 are animal influenza viruses that could infect people. However, H1N1 viruses can be divided into two groups. One group can normally infect people and the other normally infects animals. Also, H1N1 can spread from human to human, but H7N9 probably can’t, according to the World Health Organization (WHO).
Most people infected with H7N9 looked like they had the common flu. Some people had bad pneumonia(肺炎). They suffered from a fever, a cough and shortness of breath.
But don’t be afraid – it is not easy to be infected with the virus. One of the possible reasons is close contact with sick poultry (家禽) waste. People may also be infected through breath, according to National Health and Family Planning Commission.
Here are some tips from the WHO that can protect you from being infected.
Wash your hands with soap and running water before you eat, after you use the toilet, and after touching animals or animal waste.
When coughing or sneezing cover your mouth and nose with a mask(口罩)，tissue(纸巾) or a sleeve.
Get a good rest and do exercises, which will help make your body strong enough to stand up to the virus.
【小题1】What’s the name of the influenza virus that hit Shanghai, Anhui, Jiangsu and Zhejiang this March?

People are busy working every day, so they do not have enough time to do exercises. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercises every day.
There are many kinds of exercises. Bending (弯腰) and stretching (伸展) helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is sometimes called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can Jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (举重)because it can make their bodies strong. Also, we need to do some warm-up exercises before weight lifting.

_______can help you keep healthy.

A. Do exercise B. Doing exercise C. Do exercises D. Doing exercises

American schools begin in September after the long summer holidays. There are two terms in a school year, the first term is from September to January, and the second is from February to June. Most American children go to public schools.
High school students study only four or five subjects at a time. They usually go to the same classes every day, and they have an assignment(课外作业) for every class. After class they have many activities.
After high school, many students go to college. They can go to a small one or a large one. They usually have to pay a lot of money for college education (教育). But there are scholarships (奖学金) for good students, and many college students work part time in order to get money for their education.
