He often 4 us that English was very useful. And he also told us that English was quite 5 to learn if we decided to learn it well. In order to make us 6 learning English, he always asked us to recite (背诵) the text and played games 7 us in class. He also liked 8 us jokes in English. At first I could hardly understand a word and I was 9 to say anything in English. Mr James often smiled at me and said, "Don't be 10 . You are a clever boy. If you think you can, you can."
