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.

下列关于英国法的表述,正确的有:
①英国的律师制度,把律师分为出庭律师和事务律师,各负其责。事务律师不得出庭辩护,近年来事务律师可以在一些低级法院出庭辩护,但是关于两类律师的划分依然泾渭分明。②英国的辩护制度采用“辩护制”,即由原被告双方及其代理人相互辩论,法官不主动调查,充当消极的仲裁人,主持开庭审理。③英国的制定法数量不如判例法,但其效力和地位很高,可对判例进行整理、修改,现代一些重要的法律部门如社会立法即是在此基础上发展起来的。④英国的国会立法是近现代最重要的制定法,被称为“基本立法”。⑤英国的宪法具有很强的历史延续性,其渊源多样,其效力高于普通法律,修改程序也更加严格。
