I dreamed of going to the USA when I was a middle school student. When I was in high school, I made up my 　1 to go to America.

　　　 I wanted to study English and American culture. And I didn’t want to study in college in Japan at all. In Japan, it is very 　2 to enter a famous college or university but easy to graduate, so students don’t study hard after they enter the college or university. This was one of the reasons why I came to America.

　　　 I came to America last September. I have been here for eight months. When I first came here, I was very surprised. There are many differences 　3 Japan and America. I felt it was very strange and interesting.

　　　 I was also very upset because I heard English 　4 . Whenever I watched TV, went shopping, or even 　5 a walk, I heard only English. Everything was very hard for me because I could hardly understand English. Now I am used to hearing English and I can talk with Americans more easily, 　6 things are getting better.

　　　 After I came here, I realized how much I love my family, how difficult it is to live by 　7 , how exciting it is to live in another country, and how important it is to do 　8 I want to do. If I didn’t come here, maybe I didn’t realize these things. This is the most important experience in my life. I’m going to stay here for about three years. I’ll never forget the life in the USA.

There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today- the wheel. This made it easier to carry heavy things and to travel long distances.
For hundreds of years after that there were few inventions that had as much effect(影响) as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People didn’t have to explore(探测) much anymore. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all became a big part of our life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came in 1935. It changed the kind of clothes people wear.
By this time most people had a very good life, Man has a desire to explore again, the world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.
In 1969 man took his biggest step from the earth. Americans first walked on the moon. This is certainly just a beginning thought. New inventions will someday allow us to do things we have never yet dreamed of.
