【分析】
本题考查when和while引导时间状语从句的用法,核心是区分两者在时态上的搭配:while引导的从句通常接延续性动词,多用过去进行时;when可接短暂性或延续性动词,主从句时态需根据动作类型调整。解题时需先判断主从句动作是延续性还是短暂性,再转换引导词和对应时态。
【解析】
1. 原句中两个动作(玩电脑游戏、听音乐)都是延续性动作,用while连接,故填was playing computer games while。
2. 原句中“下雨”是延续性动作,需用while引导,对应过去进行时,故填was raining。
3. 原句中“我读书”是延续性动作,“下雪”是短暂性动作,转换为while引导延续性动作,主句用一般过去时,故依次填While; was reading; started。
4. 原句中“爸爸进来”是短暂性动作,用when引导,对应一般过去时,故依次填when; came。
5. 原句中“Betty做饭”是延续性动作,用while引导,对应过去进行时,故依次填While; was cooking。
【答案】
1. was playing computer games while 2. was raining 3. While; was reading; started 4. when; came 5. While; was cooking
【知识点】

2. 第2空:while引导的从句,强调过去动作正在进行时,另一个动作发生,从句用过去进行时;
3. 第3空:描述过去发生的动作,用一般过去时;
4. 第4空:when引导的时间状语从句用一般现在时表将来,主句用一般将来时;
5. 第5空:while引导的从句,强调过去动作正在进行时,另一个动作发生,从句用过去进行时;
6. 第6空:while引导的从句,强调过去动作正在进行时,另一个动作发生,从句用过去进行时;
