【问】 As the old cock crows，so crows the young. (Prov)
 请分析句子的结构。另外so crows the young中的主语和谓语必须倒装吗?
 【答】 这是一种主从复合句，as引导从句，so引导主句。它和just as... so的意义和用法相同。so主句中的主语和谓语既可倒装，亦可不倒装，但后者用得比较普遍。

 因此看来，下面的试题是有片面性的(给的答案为A，其实B也是正确的)：
 As after his death，he defeated the force of injustice_______ the position in art that hadbeen kept from during his life.
 A. so did he gain B. so he gained
 C. and he gained D. and gained(《大学英语》，1996年第12期，P. 95)

 【问】(1) As soon as the sun had set we returned to our hotel. (NCE，Book 2 ，L. 14)
 (2) He had no sooner returned than he bought a fine house. (NCE，Book 2，L. 38)
 问题1：as soon as和no sooner... than的意思是否相同?
 问题2：as soon as和no sooner... than在结构上有什么区别?
 【答】 (1)as soon as与no sooner... than所表达的意思是相同的，都表示它所指的动作发生在另一分句所指的动作之前，并且都可译作“刚……就”。但是no sooner... than常常含有惊奇的意思。
 1. He had no sooner reached the door than he came back. (Dreiser)
 他刚到门口就返回来了。
 2. We had no sooner set out than a thunderstorm broke. (Wood)
 我们刚出发，就发生了暴风雨。
 3. The plane had no sooner taken off than it returned. (NCE)
 飞机刚起飞，就返回来了。
 (2)从结构上看，as soon as引出的是(时间状语)从句，而no sooner…引出的则是主句，than引出的是从句。另外，当no sooner位于句首时，其中的主语和谓语必须实行部分倒装：
 1. No sooner had he gone to sleep than the telephone rang once more. (Millington)
 他刚睡着，电话铃就又响了。
 2. No sooner had the meeting started than there was an uproar. (CGEL)
 会议刚一开始，就发生了喧嚷。
 3. “Did John see the accident?”“No，no sooner had he gone than the accident happened. ”(Michigan)
 “约翰看到事故了吗?”“没有，他刚走，事故就发生了。”
 as soon as与no sooner... than还有一个区别：as soon as可以与动词的一般现在时，一般过去时或过去完成时连用(主句可与动词现在时、过去时、将来时连用)，而no sooner...则只能与过去完成时连用(than从句只能与一般过去时连用)：
 1. “When can the doctor see me?”“ As soon as_________. ”
 A. he will be back from the hospital B. he can be back from the hospitalC. he back from the hospital D. he gets back from the hospital(TOEFL，75. 5)
 2. As soon as I got home my brother went out. (JED)
 我刚一到家，我哥哥就出去了。
 3. As soon as he had got into the car，I said good morning to him in French and he repliedin the same language. (NCE，Book 2，L14)
 他一上了车，我就用法语向他道声早安，他也用法语作了回答。
 4. As soon as he had done it，he knew it was a mistake. (Chambers)
 他刚一做完这件事，就知道了这是错误的。
 5. No sooner had he arrived than he began to complain. (MED)
 他刚一到达就开始抱怨。
 最后，as soon as引出的从句可以放在主句之后，而主句no sooner却不能放在than分句之后：
 He started as soon as he received the news. (OSD)
 他一得到消息就出发了。
