Schools in the U.S. generally do not have a specific teaching plan for teachers to follow, and they certainly don’t have a set of textbooks that are taught by all school districts throughout the country. That’s why textbooks vary greatly from school to school, and from teacher to teacher even though they are all teaching the same subject in the same grade. Some schools provide books to use, but teachers do not strictly follow them. They only use them as a reference, and enjoy pointing out mistakes and wrong information given in the books. They often share their own points of view with their students. Teaching like this has many advantages. Teachers can bring out their expertise, fully elaborating their most familiar areas. Students are more interested in what they are studying. Also this flexible teaching style. benefits students in the development of critical thinking skills and the ability to apply them. On the other hand teaching like this also has many drawbacks. It causes uneven study levels. It is even more so among different schools and districts. Students in the same grade do not usually have a thorough understanding of a subject taught in the same school year. The teacher for the following year would have to spend a lot of time finding out what the students already know or do not know in the subject before starting his/her own teaching plan. Some parts may be repeated, resulting in waste of time; and other parts may not be covered at all.

Exams in American schools are much less rigid than those in China. Teaching is flexible, so are exams. Even if you memorized the whole textbook, it might not be of much help in the exams. My Chinese friend envied me for nothaving to worry about the competition for attending the best schools by takingendless exams.

Weather 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．

Before， I thought that a man who was wise and good would become rich， but now I know this is not always true． I learned it from my teacher． He is both wise and good， but he is not rich at all． He may become rich if he gives up(放弃) teaching and goes into business． But he likes his job and thinks it，s wonderful to help young people． He stays at school from morning till night and works very hard． He always smiles at us when we go to ask him for help． He is kinder to us than any other teacher in our school． I think it must be easier to learn history or math than to learn how to become a man like him． He scolds(责备 ) us when we do something wrong，but it makes us try to do better．We all wish to study with him as long as possible． But that may be impossible． Some of us may become doctors， some become businessmen， some be- come engineers， some become writers， but we all want one thing very much． It is that we all want to be teachers in the future．
