例：We often visit the museum last year. 答案：visit改为visited
Last month, my English teacher asks me to take a part in an English speaking competition. But I doubt that I have the ability to win. It is known to all my classmates that I can always speak English as good as a native speaker. However, I dare not express my ideas, especially in public. My best friend Lisa has been encouraging me accept the challenge.
On her opinion, as long as I try my best, I will make it. After hear this, I have decided to have a try. I hope I will be luck.
