Different weather makes people feel different. It influences health, intelligence and feelings.

In August, it is very hot and wet in the southern part of the United States.   51   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 of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower.   52  Very hot weather, on the other hand, 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.   53   They even don’t like to do outdoor activities.

Low air pressure may make people forgetful.   54   There is “good weather” for health. People feel best at a temperature of about 18℃.

Are you feeling sad, tired, forgetful, or unhappy today?   55 

A．It may be the weather’s problem.

B．Warm weather can have a bad effect on health.

C．The wind can help people have more intelligence.

D．But fat people may have a hard time in hot summer.

E．people may have more intelligence when low air pressure comes.

F．People leave more bags on buses and in shops on low-pressure days.

G.．People there have heart trouble and other kinds of health problems during this month.

It will be hot—hot enough that most locals will have cleared town for cooler places. But because athletes competing at the 2004 Olympics have no choice but to stay in the hot weather, many plan to turn to science to stay cool.?

Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(织物) designed with hot weather in mind.?

“Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we're taking the warm out of warm up. It's like pre-cooling.”

Experts are predicting(预测) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).?

Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures.?       Drinking lots of water will help athletes keep cool, but humidity(湿度) remains a problem. The body's ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸发),resulting in dehydration(脱水) without the cooling.?

“Getting hot is a real problem because when our brains heats up, the brain waves are more like when you're really sleepy. Everything feels harder,” said Sleivert.

The passage mainly tells us that _______.

A. why it is very hot in Athens?

B. the hot weather is a big problem for Olympic athletes?

C. how important science is to every athlete?

D. the Olympics will be put off because of the hot weather?
