AWeather has a great influence(影响) on people．It influences people's 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 disease and other kinds of health problems during this month． In the Northeast and Middle West, it is very hot at some times and very cold at other times．People in these places may have heart disease after the weather changes in February or March．The weather can also influence intelligence． For example, in a 1982 study by scientists, the in scores of a group of students were very high during a storm, but after the storm their IQ scores were lower than usual level． So storms can increase intelligence．However, very hot weather can lower it． Students in the United States often do badly on exams in the hot months of the year．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 and they may feel unhappy during cold weather． In hot summer weather, on the other hand, fat people may feel unhappy． The sum- mer heat may make them tired and they are easy to get angry．( )21．lf thin people feel unhappy, the weather may be very _________．A．warmB． coldC． coolD． hot

根据下列材料请回答 31～35 题：ANow satellites are helping to forecast the weather．They are in space，and they can reach any part of the world．The satellites take pictures of the atmosphere(大气)，because this is where the weather form．They send these pictures to the weather stations．So meteorologists(气象学家)can see the weather of any part of the world．From the pictures，the scientists can often say how the weather will change．Today，nearly five hundred weather stations in sixty countries receive satellite pictures．When they receive new pictures，the meteorologists compare them with earlier ones．Perhaps they may find that the clouds have changed during the last few hours．This may mean that the weather on the ground may soon change，too．In their next weather forecast，the meteorologists can say this．So the weather satellites are a great help to the meteorologists．Before satellites were invented，the scientists could forecast the weather for about 24 0r 48 hours．Now they can make good forecasts for three or five days．Soon，perhaps，they may be able to forecast the weather for a week or more ahead．第 31 题 Satellites travel______．A．in spaceB．in the atmosphereC．above the groundD．above space

Questions 11 to 15 are based on the following passage.
Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.
But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
If children have flu-like symptoms, their parents （）A、are advised not to give them aspirinB、should watch out for signs of Reye syndromeC、are encouraged to take them to hospital for vaccinationD、should prevent them from mixing with people running a fever
