　Our eating habits （习惯）are very important for good health and a strong body. There are times when most of us like eating sweets and ice-cream better than meat and rice. Sweets and ice-cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite(食)。It's important for us to eat our meal at regular （规律的）time each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges often decided whether a man was telling truth by giving him some dry bread. If the man could not swallow the bred, it meant that he wasn't telling the truth. Though this seems strange and foolish, they though it was an excellent way of finding out truth. A man who is worrying something has difficulty in swallowing anything dry, because he loses his appetite.

It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold! Wait a moment. Could it just be a common cold or the flu (流感) that’s been going around?
A cold gives you a runny nose and cough. But it’s usually easy to deal with. Some take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.
On the other hand, the flu can be much more dangerous. It usually gives you fever. Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.
Don’t worry. If you get a flu vaccine (疫苗), it can stop you from getting the virus (病毒). Flu vaccines work by giving the body a small amount of flu viruses. This causes your body to develop antibodies (抗体). So next time you get the flu, the antibodies should help you.
The flu virus changes every few years. Therefore, there are so many types of flu, such as H1N1 and H5N1. The antibodies for one type of flu can’t help us against all types of flu. That’s why we need to get the vaccine every year.
However, good health habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen your immune system (增强免疫系统).
【小题1】If you have a common cold, usually you’ll feel better after ________.

The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧运动), strength building, and flexibility (柔韧) exercise. Make exercise a habit by arranging some time every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.
Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are five simple ways to make an exercise lifestyle change:
