     Have you ever met anyone of your age from America? Do you think you would have a lot in common
  with middle school students there?
      With only one look, you can see lots of differences. For example, classes in American schools are
  smaller than yours. Most classes have no more than 30 students. Most students in the US don't wear
 school uniforms. And they don't have group exercises each day as the way you do. If they see your
 exercises, they will think you are very strange!
      In fact, Chinese students and American students have very different lives.
      What's the first thing you think about when you wake up in the morning? It's probably your lessons at
 school. Chinese students are very hard-working, always under lots of pressure (压力) from their parents
 and teachers.
      Chinese students study hard at night, and sometimes even on the weekend because their exams are
  very important.
      For Chinese students, school is life, but not for American students. They don't have to worry about
 passing exams all the time, so they can spend time in and out of school doing things they enjoy. Kids do
  different things for fun.
      Many American teachers think that just studying hard isn't enough to make a good student. They
 encourage (鼓励) students to try lots of different things.
