Weather has a strong effect(影响) on people. It influences health, intelligence (智力) and feelings. In August, it is very hot and wet in the southern part of the United States. People there easily have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is hot at some times and very cold at other times. People in those states will have heart trouble after the weather changes in February or March.
The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of some college students were very high during storm, but after the storm, their scores were low. Storms can increase intelligence. Very hot weather, on the other hand, can decrease(减少) it. Students in many schools of the United States often do badly in exams in the hot months of the year(July and August).
Weather also has a strong effect on people's feeling. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel depressed during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 65F, people become stronger.
Low air pressure(气压) makes people feel free, but it also increases forgetful- ness. People leave more bags and umbrellas on buses and in stores on low pressure days. There is a“perfect weather”for work and health. People feel best at a tempera- ture of about 64F with 65 percent humidity(湿度).
Are you feeling sick, sad, tired, forgetful, or very intelligent today? The weather may be the reason.
【小题1】Intelligence may be lower______.
A．during a stormB．when it is sunny
C．on a very hot dayD．when you take in an exam
【小题2】 In the third paragraph,“depressed”means         .
A．兴奋的B．愉快的C．忧郁的D．担心的
【小题3】 In“perfect weather”,          .
A．both the fat and the thin are healthy
B．the students do very well in examinations
C．the air pressure is low
D．the humidity is 65 percent and the temperature is about 64F
We know that many animals do not stay in one place. Birds,fish and other animals move from one place  to another at a certain time. They move for different reasons: most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration（迁移）is probably the migration of the fish which is called “salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life. When it is old,it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they bccome too crowded. They move down to the low land. Sometimes they move all the way the seadide,and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of kind of lobster（龙虾）.Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody know where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t. Maybe living things just like to travel.

500 years ago in Britain, the burning of coal (煤) was increasing in cities like London. Coal was used in factories and also used to heat homes. Coal, when burnt makes a lot of smoke, which makes the air very dirty.
About 200 years ago, the Industrial Revolution (工业革命) began in Britain. Factories were built, and even more coal was burnt. Air pollution was becoming a really big problem.
Smoke and fog together make smog (烟雾). Smog was a big problem in London's winter. Because of the cold weather, more coal was burnt to warm houses and this made more smoke.
When smog stayed over a city, it became really hard to breathe and see clearly. In 1952, the Great London Smog happened and more than 4,000 people died because of the smog.
New laws (法律) were made in 1956 and 1968 to stop such sad things from happening again. These laws were called the Clean Air Acts.
These laws were made so that air would become cleaner. The laws encouraged people to use less coal or switch to other fuels such as gas. Factories started using tall chimneys (烟囱) so that the smoke would go high up in the sky and no longer cover cities, and new factories were built in the countryside. Smog appeared less often and the air became cleaner.
【小题1】From the passage, we learn that smog was a big problem in ______ in London.

A．springB．summerC．autumnD．winter
【小题2】The underlined words "switch to" mean "______"  in Chinese.
A．发明B．换用C．拒绝D．节省
【小题3】Which was NOT a way people in Britain used to make the air cleaner, according to the passage?
A．Factories built higher chimneys.
B．People began to use less coal.
C．More People began to ride bikes.
D．New factories were built outside cities.
【小题4】Which is the best title for the passage?
A．Air Pollution in Britain in the Past.
B．How to Make the Air Cleaner.
C．Smog Is Bad for the Environment.
D．New Laws to Stop Air Pollution.
