C. 在陈述句中

　　陈述句在一般情况下用自然语序;但由于英语语法的某些原因，陈述句也要使用倒装语序。这些原因大致可以归纳

　　1) 为了避免句子部分内容不必要的重复，常用"so + be动词(助动词、情态动词)+主语"或"neither / nor + be动词(助动词、情态动词)+主语"的倒装句式。其中第一个句式表示"与前面所述的肯定情况相同"， 第二个句式表示"与前面所述的否定情况相同"。例如：

　　His brother is a college student; so is mine.

　　他弟弟是大学生，我弟弟也是。

　　His brother is not a college student; nor is min .

　　他弟弟不是大学生，我弟弟也不是。

　　He used to have his further study abroad; so did I.

　　他曾去国外深造过，我也去过。

　　He didn‘t use to have his further study abroad; neither did I.

　　他没去国外深造过，我也没有。

　　One of my friends can speak three foreign languages; so can his wife.

　　我的一个朋友会说三门外国语，他的妻子也会。

　　One of my friends cannot speak three foreign languages; neither can his wife .我的一个朋友不会说三门外国语，他的妻子也不会。

　　They are now preparing for their final examinations; so are we .

　　他们正在为期末考试作准备，我们也一样。

　　They are not now preparing for their final examinations; nor are we .

　　他们没在为期末考试作准备，我们也没有。

　　2)具有否定意义的词或短语置于句首时(除否定词修饰主语外)，句子一般要写成部分倒装句。这类词或短语常见的有：not, never, seldom, hardly, rarely, scarcely, by no means, under no circumstances, in no way, at no time, no sooner … (than), hardly … (when), not only … (but also), not until… ,等。例如：

　　Hardly had she sat down when she heard someone knocking at the door .

　　她还没来得及坐下来，就听见有人敲门。

　　Not until twelve o‘clock did he go to bed last night .

　　他昨晚直到十二点钟才睡觉。

　　Never have my sisters been to Hong Kong before .

　　我的妹妹们以前从未去过香港。

　　No sooner had I returned home from New Zealand than I bought a house and went to live there.我从新西兰一回国，就买了一栋房子并在那儿住下了。

　　So far as I know, seldom does Mary come back to see her mother.

　　就我所知，玛利几乎很难回来看她妈妈。

　　Scarcely a drop of rain fell here last fall . (否定词修饰主语时，句子不用倒装。) 去年秋天，这儿几乎没下一滴雨。

　　3)当so, often, only等表示程度、频率的副词放在句首时，句子一般要倒装。例如：

　　Only in this way can you come up with a solution to the problem.

　　只有这样，你才有可能想出解决这个问题的办法。

　　So serious was the situation that everybody faced a test.

　　形势如此地严峻，每个人都面临着一场考验。

　　So hard did he overwork that he fell ill at last. 他太操劳过度以致最后病倒了。
