文档标题和描述中提到的是一个英语语法练习,主要涉及状语从句和定语从句的混合使用。在英语语法中,状语从句通常用来修饰动词、形容词、副词或整个句子,表达时间、条件、原因、结果等关系;而定语从句则用来修饰名词或代词,起着形容词的作用,给出被修饰词的更多信息。
从给出的部分内容来看,我们看到了多个填空题,每个题目都涉及到特定类型的从句:
1. "don't know whether he is at home or not" 这里使用了whether引导的宾语从句,表示不确定的状态。
2. "man and the horse... fell into the river were drowned" 这是一个定语从句,用"that"来指代前面的"man and the horse"。
3. "I really don't know what to do" 这是know后面接的宾语从句,用"what"引导,表示不知道做什么。
4. "don't know whose pen it was" 这同样是一个宾语从句,同时也是一个定语从句,"whose"作为关系代词修饰"pen"。

6. "I don't know whether Mr. Green will come to see us" 这里再次使用了whether引导的宾语从句,表达不确定Mr. Green是否会来。
7. "Be careful! Don't break the bottles. Do you hear I said David? -- Yes, Mum." 这里"Do you hear"后面是一个宾语从句,省略了引导词"that"。
8. "Could you ring me up as soon as he arrives" 使用了"as soon as"引导的时间状语从句,表示一到就打电话。
9. "The doctor who/whom is leaving for London next month" 这是一个定语从句,who/whom修饰"doctor"。
10. "Do you know who the nurse is talking to" 这里"who"引导宾语从句,询问护士正在跟谁说话。
11. "He has been in the factory for two months since he left school" "since"引导了一个时间状语从句,表示自从离开学校以来。
12. "Do you know where Mr Black's address is" 和 "He may live at No. 19 or No. 18 of Bridge Street" 这里"where"引导宾语从句,询问地址在哪里。
13. "There is not much difference between the two. I really don't know which I should choose" 这里"which"引导宾语从句,表示在两者之间选择。
14. "My young sister who is eighteen years old is a college student" "who"引导的定语从句,修饰"sister"。
