阅读下面的短文，并根据短文后的要求答题。
According to a new survey, students’ safety has become a big problem. Nearly 50% of students say they are worried about robbery on the way to and from school. Now in many big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No. 25 Middle School, gives young students advice on how they should deal with danger.
If you are robbed
Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later.
If you are in a traffic accident
If a car hurts you, you should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. This is because you don’t know how seriously you are hurt.
If it is raining hard and there is lightning
Don’t stay in high places and stay away from trees.
When there is a fire
Get away as fast as you can. Put wet things on your body and try to find an exit. Do not take the lift.
If someone is drowning
If you can’t swim, don’t get into the water. Cry out for help.
Remember that danger is never as far away as you think. Take care of yourself at all times!将文中划线句子翻译成汉语:

Different weather makes people feel different. It influences (影响) health, intelligence (智力) and feelings.
In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.
The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ (智商) of a group students were very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面), can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).
Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18C, people become stronger.
Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is a “good weather” for work and health. People feel best at a temperature of about 18 centigrade (摄氏度).
Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather’s problem.People may have more intelligence when _____ comes.
| A．a rain | B．very hot weather |
| C．a strong wind | D．low air pressure |

| B．weather influences people’s lives |
| C．IQ never changes during weather changes |
| D．There is a good kind of weather for people’s work and health |
