2. C。keep sth. doing 表示“使……持续某种状态”。
3. D。本题中catch意为“碰上”、“撞见”，catch sb. doing sth.表示“撞见某人正在做某事”，用-ing形式作宾语补足语。
4. A。第1空，interesting作
6、定语,修饰anyone；第2空, boring作宾语补足语。
5. D。caught stealing在此作定语, 修饰the girl，相当于who was caught stealing，-ing形式作主语补足语。
6. B。此处-ing形式作宾语补足语，表示宾语主动且正在进行的动作。leave sb. / sth. doing sth.“使……一直做…… / 持续某种状态”。
7. A。第1空，missing“丢失的”, 用作定语；第2空是see sb. doing sth.的被动结构：sb. be seen doing sth.; playing作主语补足语，强调动作正在进行。
8. B。此处是find sb. doing sth.的被动结构， smoking作主语补足语。
