部分倒裝用法歸納

部分倒裝，即將主語與助動詞倒置，其結構與一般疑問句大致相同。英語中構成部分倒裝的主要情形有：

1. 含否定意義的詞(如 never, hardly, seldom, little, few, not until, not, not only, no sooner, no longer, nowhere, by no means 等)置于句首時，其后用部分倒裝。如：

Never have I seen read such a book. 我從未讀過那樣的書。

Little do we know his life. 我們對他的生活了解得很少。

By no means should you tell him about it. 你絕不要告訴他這事。

2. only 加狀語(副詞 / 介詞短語 / 從句)放在句首時，其后用部分倒裝。如：

Only in this way can you do it well. 只有這樣你才能做好。

Only when he returned home did he realize what had happened. 當他回到家里時，才知道出了什么事。

3. so / neither / nor 表示前面所說的情況也適合于后者時，用“so / neither / nor+助動詞+主語”這樣的倒裝句式。如：

He can sing English songs and so can I. 他會唱英語歌，我也會。

He didn’t see the film, and neither did I. 他沒有看這部電影，我也沒有看。

She is every beautiful and so was her mother when she was young. 她很美，她媽媽年輕時也很美。

4. 當虛擬條件句含有 were, should, had 時，可省略 if，將 were, should, had 置于句首。如：

Were I Tom(=If I were Tom), I would refuse. 如果我是湯姆，我就會拒絕。

Had I realized that(=If I had realized that), I would have done something. 我要是明白了這一點，我可能會采取某種行動(from www.hz123456.com)。

5. so...that 結構中，將 so+adj. / adv. 置于句首時，其后要用倒裝語序。如：

So cold was the weather that we had to stay at home. 天氣太冷，我們只好呆在家里。

So fast does light travel that we can hardly imagine its speed. 光速很快，我們幾乎沒法想像它的速度。
