答案:【计分规则】: In the morning, take the school bus to go to bai for school. There is a class at 8 o'clock, a 45-minute session, a four-session at morning, and a three-session at three o'clock in the afternoon. What I want to say here is that American students do not have a fixed class. They have different students in different classes, there are four compulsory courses (American History, English, Mathematics, and Science), and three elective courses, so that they can basically know the grade. All classmates. My friend’s electives are Gym, Spanish and Band. He likes sports the most. I followed him to a basketball class and a frisbee class (similar to handball, with special rules, which is fun). Their main subject is more formal, but you can also get the paper from the seat, go to the toilet and go directly, without raising your hand to tell the teacher. In terms of difficulty, mathematics is really simple as long as it passes the language. When I went, they were studying logic and replacing them in equal amounts. But English and history are more strenuous. Basically, they can't understand what they are saying, but they can't understand clearly the details. So when I was in these two classes, I kept dozing off and started to work hard to listen and later gave up. Science is quite interesting. The teacher did the experiment, made a solar system with a flashlight and a plastic ball and hung it on the roof of the classroom, talking about the water cycle and the rotation of the earth. Spanish is much the same, and the orchestra is a wind orchestra, blowing under the guidance of the teacher.
