If ( it is) necessary, ring me up. e. He didn’t say a single word until ( he was ) asked. 3.as和than引导的比较状语从句中, 从句中和主句中相同的部分往往省略, 从句中只剩下比较对象 a. He is a head taller than I ( am tall ). than之后的人称代词是主格或宾格时, 有时意思不同, 如: a. She likes the dog more than me.=She likes the dog more than she likes me.她喜欢狗比喜欢我更多 b. She likes the dog more than I.=She likes the dog more than I like the god. 她比我更喜欢狗 4.含有no sooner…than…和hardly / barely / scarcely …when…的句子相当于含有as soon as…引导的时间状语的句子. no sooner或hardly放在句首时, 主谓要部分倒装 a. He had no sooner seen the policeman than he ran away. =No sooner had he seen the policeman than he ran away. =He ran away as soon as he saw the policemen. b. He had hardly sat down when the telephone rang. =Hardly had he sat down when the telephone rang. =The telephone rang as soon as he sat down.
