I came to the USA because I needed to study English here. I went to an English language school. I was not a beginner, but I was not good at English. At the end of the first term, I could read, write and speak, and I thought I was good at them. However, I was not good at understanding (理解) when people spoke to me. My teacher said,” Why don't you repeat (重修) the classes?” I was not happy. I made progress (进步) every month, so I did not want to repeat them. However, it was true — I was not good at understanding when people spoke to me. My teacher said, “Repeating the classes is a good way to practice listening. And if you repeat them, you will understand more spoken English.” In the end, I repeated the classes. In the second term, I studied the same books that I did in the first term. My teacher was right. It was a good idea. Now, after studying English for a year, I can understand more spoken English. And I know that reading, writing and speaking are not enough; listening is also very important.
