Lisa: You mean the English speech contest next week?
Mike: Yes. I hope I can win!

47. How did you change?
48. That's a smart way!

【分析】
补全对话需紧扣上下文语境梳理逻辑：46空承接Mike“之前不是这样”的表述，结合下句Lisa的提问“你过去很紧张？”，需填Mike过去的状态；47空承接Mike“过去怕犯错”的表述，Lisa需询问他改变的方式；48空是Lisa对Mike分享的应对方法的评价；49空回答Lisa关于“在公众说英语的感受”，结合后文Mike要参加演讲比赛，需填对应感受；50空是Lisa对Mike参加比赛的鼓励。
【解析】
1. 46空：前句Mike提及“之前不是这样”，后句Lisa问“你过去很紧张？”，故填体现Mike过去状态的句子：I used to be nervous to speak English.
2. 47空：Mike说过去怕犯错，Lisa询问他改变的方法，故填How did you change?
3. 48空：Mike分享了应对方法，Lisa评价该方法，故填That's a smart way!
4. 49空：问在公众说英语的感受，后文提到要参加演讲比赛，故填体现自信的句子：I feel much more confident.
5. 50空：Mike希望比赛获胜，Lisa给予鼓励，故填Good luck! / I believe you can make it.
【答案】
46. I used to be nervous to speak English.
47. How did you change?
48. That's a smart way!
49. I feel much more confident.
