I'm Chinese ,but I am in England now. I can speak English. But I sometimes make mistakes with English. It was sunny yesterday. My class went to the park. I said,“Let's fly cats in the park. ”My classmates all laughed. I didn't know why. Then my teacher said,“Cats are animals. We can't fly them. But we can fly kites. ”“I know my mistake. I wanted to say kites,not cats. ”I said. Then we laughed again. That was funny.
