In winter and spring, the flu is a kind of serious illness. In fact, it is hard for you to stay away from it. However, there are some ways to cut down the possibility of catching it.

    1    

According to a study, the immune system (免疫系统) in the body doesn’t work well in the cold weather, while viruses (病毒) don’t like the warm body. So wearing enough clothes may help keep away from them.

    2    

Although it’s possible for you to keep away from another’s coughing, you’re more likely to pick up viruses from something you touch. “Wash hands often. If there is no way to clean hands, try not to touch your eyes or nose,” said Dr. Walton. “This is a common way for viruses to get into your body.”

    3    

When you’re sleeping, your body is able to produce something to fight with viruses. People who sleep for seven to eight hours will have a stronger immune system than those who sleep less. According to Dr. Walton, if you can’t get enough sleep during the night, a 30-minute daytime nap (打盹) is enough to make up for the bad effect of the poor nighttime sleep on the immune system.

Taking enough exercise can keep the immune system working better. However, doing too much exercise may bring some bad results. For example, you may catch viruses more easily.

    5    

To keep away from the flu, having flu jabs is necessary and important. “It’s true that the jab can’t protect us against all kinds of flu, but it can save lives. I’m sure to have one every year,” says Dr. Walton.

【推荐3】As we know, the desert covers large areas of the Earth. In the desert, there is very little rain and it is very hot in the day and so cold at night. If you are a hiker (徒步者) or drive through the desert, it might be wise to know what you should do in order to be saved in the desert.

Drink a little water every hour. If you find a small piece of land where the earth is wet, dig deep to look for water. Another method of getting water is to cover a green plant with a plastic bag. As it breathes, the water vapor (蒸汽) will be collected inside the bag. Little by little, you can collect enough water to drink.

Plan to travel at night and sleep during the day, if you find you have to stay in the desert for a period of time. If you can find any shade (阴凉处) in the desert, use it to protect you from the strong sunlight.

Wear clothing in light color. It may seem like you’ll be cooler if you wear that kind of clothes, which actually helps your body to become cool and helps protect you from sunburn.

Prepare to signal (发信号) planes passing overhead if you are caught in the desert. During the day keep a smoky (有烟的) fire burning and at night, a bright, clean burning one. Spell out the word SOS on the ground as large as you can using whatever materials you can find. In this way, you have more chances to be saved.

【推荐2】Do you like Dinosaur Island?

The film Dinosaur Island? I went with my younger brother Dave to see it last Friday. I had a great time, but he closed (闭上) his eyes in many parts because the dinosaurs (恐龙) looked so real and he didn't laugh once. I thought the story was really exciting. The beginning and the ending were excellent!   

—George

I saw the advertisement (广告) for the film Dinosaur Island on TV. It looked great but it wasn’t as good as I hoped. I loved the beginning but the second half was boring, I think. I wouldn’t go and see it again. I like films about teenagers and their lives much more. I also like reading books about teenagers. I'd like to be a writer and write for teenagers one day.

—Robert

I didn’t want the film Dinosaur Island to end because I liked it so much! I read this story before I saw the film. I usually enjoy the books more, but this time was “ ▲” . I really loved the film! I read all about how they made the dinosaurs on the Internet after I went to see it. I think most young people will love seeing this film!

Being safe at school and in your everyday life needs knowledge. If you remember the following information, your life will be much safer.

Always notice the environment around you. You shouldn’t walk alone outside Make sure where the public phones are. If anything dangerous happens you can find them quickly.

Don't use earphones (耳机) when running in the playground or on the street. You will keep yourself from the outside world and can be easily surprised.

The school bag should be carried towards the front of your body instead of putting it on your back. When buses are crowded, it is easy enough for thieves to steal the things in your bag on your back.

If you are followed by a stranger, cross the street and go in the other direction; let the stranger know that you know he or she is there. Next, go and get help from others if it is necessary. Don't go home directly. You are safer on the street than you are in your home or in a lift.

If you have to take a bus to a place far away, try to get to the stop few minutes before the buses leave. This prevents a stranger from studying you. On buses, don’t sit alone, sit behind the driver or with friends. Don’t sleep.

Don’t play with matches or candles, because it may cause fire. If your house catches fire and you have to escape through smoke, move on your hands and knees with your head 30 to 60 cm above the floor. Please remember there is cleaner, cooler air near the floor during the fire.
