Read and answer the questions.
Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather’s fault (过错;责任). Different weather makes people feel different. 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 have heart trouble and other kinds of health problems during this month. In the northeast and the middle west, it is very hot sometimes and very cold sometimes. 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 study by scientists showed that the IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was lower. The wind can help people have more intelligence.
Weather also has a strong influence on people’s feelings. Low air pressure(气压) may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is “good weather” for work and health. People feel best at a temperature of about 18℃.
