解释这两句后基本上可以把倒装句的主要规则弄清楚了。
1. When I came that evening, the door of the Cookesy's sitting-room was open and through it came laughter, stamping offeet, and television music. 如你所说是由于后面的主语太长,置于句首后,后面的through it显得太短,引起句子“头重脚轻”,而且对于读者阅读来说,句子也有“
失重”感。through it前置后,可以与句子前面的"the door"吻合,主题先提出来;
2. To this class belongs the most astonishing work that the author accomplished.这一句先将
介词短语"To this class"置于句首,然后才是主语"the most astonishing work ..."。这样处理的原因主要是"the most astonishing work ..."后面有一个
定语从句,这是作者应用倒装句行文的最佳方案。不妨将此举句子还原:"The most astonishing work that the author accomplished to this class belongs."。我们马上就发现定语从句在这里将主句的主谓部分割裂的很远,不说作者的行文困难读者阅读时也费解。(这里的"belong to ..."是词组)
3.
英语倒装句分为完全倒装与部分倒装。全句倒装是将谓语部分都放在主语前面:
A. Here are some registered letters for you.
B. In came a man with a white beard.
部分倒装(只是组动词,
情态动词,系词"be"等):
A. At no time will China ever behave like a superpower.
B. I couldn't answer the question. Nor could anyone else in oue class.
更多其他的倒装句形式与特殊性,内容较多,不在此一一例举了,你可以查阅相关语法书的“句子语序”栏目。
很好,祝你成功!
