Module 4 Seeing the doctor
单元话题阅读理解
一、阅读理解
Medical experts(专家)say most Americans do not get enough sleep. They say more Americans need to take a nap— to rest for a short period in the middle of the day. They give people advice to sleep lightly before continuing with other activities. The experts say naps might improve health by reducing pressure(压力).
Some European and Latin American companies have supported the idea of napping for many years. They ask people to leave work, go home and have a nap before returning to work. In the United States, some companies let workers rest simply in their offices. They believe this can help workers make fewer mistakes and also increase the amount of work of their workers.
Sleep experts say it is likely that people make more mistakes at work than at other times. They say people should not carry out important tasks when they feel sleepy. And they say the best thing to do is to take a nap. About twenty minutes of rest is all you need. Experts say this provides extra energy and can increase your effects(效果)of the day. But experts said that a nap should last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be difficult.

Early to bed and early to rise makes a man healthy, wealthy and wise.
This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.
Is this true Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you do not go to bed early, you can not have enough sleep. Then you can not think properly and you can not do your work properly. You will not be wise and you may not become wealthy！
Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us to sleep well.
When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.
Exercise helps the blood to move around inside the body. This is very important. Blood takes nutrition（营养）to all parts of our bodies. The brains in our heads also need blood. We think with our brains. If we keep our bodies healthy，and take exercise, we can think better！
Our bodies also need air to breathe. Without air we will die. Get up early in the morning and we can have plenty of clean，fresh air. That will keep us healthy and happy.

We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may also help us live longer.
Recently, researchers studied more than 55, 000adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average, three years longer than the non-runners.
Running may be good exercise. But it can be difficult on the body. Here are commonly shared ideas among fitness experts(健身专家)to lower the risk of injury(受伤) for a beginner.
▲Take it easy.
Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance (里程)or speed.
▲Get good running shoes.
You should find the shoes to offer the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometres.
▲Take good notes.
Take time after each run to write down notes about your exercise and your feeling of it. Look for things happening again and again. For example, you may find that your knees hurt when you run sometimes. But perhaps you feel great when you have a rest between running days. These notes will help you make the best plan for running.
22．In the second paragraph, we know ________.
A．a good habit of running may help you live longer
