(他刚睡着，电话铃又响了。) 2)He had no sooner reached the door than he came back.(他刚走到门口就走回来了。) 3) He had hardly had time to realize what was happening when she pushed him out of the room.(他还来不及弄清发生了什么事，突然她把他推出房间去。) 4) He acted as if he had done something great.(他一举一动好象他做了一件什么了不起的事似的。) 5) I had written him three letters before he wrote back.(在他回我信之前我曾写给他三封信。) 6) They had lived in many countries before they settled in England.(在他们定居英国之前，他们曾在许多国家主过。) 7) I had hardly opened the door when he hit me on the head.(我刚开门他就一拳打在我的头上。) 8) We had hardly arrive when it began to snow.(我们刚到就开始下雪了。) 9) Hardly had we arrived when we had to go back.(我们刚到就不得不返回。) 2.no soonerthan, 这个 than 很多人好象都喜欢写 then , 似乎认为 then 比 than “说得通”。可是这毕竟是固定的搭配，不能一自己的想象来代替。 3. continually 与 continuously，前者是有间隙停顿的“不断”，后者则是有连续性的“不断”。例： 1)The baby is continually crying.婴儿不断地哭。 2)The river flows continuously.河水不断地流。 仅供学习与交流，如有侵权请联系网站删除 谢谢5
