即运用关系代词、关系副词或从属连词改写。如
1. The man is talking with a lady. He gave us a talk last week.
The man _________ gave us a talk last week _________ _________ with a lady.
【答案】who / that; is talking。定语从句who / that gave us a talk last week修饰先行词the man。
2. He didn’t want to miss the first bus, so he got up early.
He got up early _________ _________ he could catch the first bus.
【答案】so that。目的状语从句so that he could catch the first bus说明动词got up early的目的。
3. “Did you sleep well last night?” David asked her.
David asked her _________ _________ _________ well last night.
【答案】if / whether she slept。直接引语转换成间接引语时，如果直接引语是一般疑问句时，连接词要用if或whether，句子保持陈述句的语序。
4. Come on, or we’ll miss the early bus.
_________ we _________ hurry, we’ll miss the early bus.
【答案】 If; don’ t。if 引导条件状语从句。句意为：如果我们还不快一点，我们就赶不上头班车了。
祈使句与条件状语从句的相互转换。
5. John will go to bed after he finished his homework.
John _________ to bed _________ he finished his homework.
【答案】didn’t; until。not…until表示“直到……才”的意思。
