英語中，有部分倒裝和全部倒裝。如，
Does he like English? 是部分倒裝形式。正常的應該是：He likes English.
Up goes the price. 是全部倒裝。正常的應該是：The price goes up.
語法 | 高中英語語法 之 倒裝
1. 「so+助動詞+主語」倒裝
當要表示前面提出的某一肯定的情況也同樣適合於後者，通常就要用「So+助動詞+主語」這種倒裝結構：
You are young and so am I. 你年輕，我也年輕。
She likes music and so do I. 她喜歡音樂，我也喜歡。
If he can do it, so can I. 要是他能做此事，我也能。
【注意】
(1) 若前面提出某一否定的情況，要表示後者也屬於同樣的否定情況，則應將其中的so改為neither或nor：
You aren’t young and neither am I. 你不年輕，我也不年輕。
She hasn’t read it and nor have I. 她沒有讀它，我也沒有讀。
(2) 注意該結構與表示強調或同意的「so+主語+特殊動詞」結構的區別：
"It was cold yesterday." "So it was." 「昨天很冷。」「的確很冷。」
"Father, you promised." "Well, so I did." 「爸爸，你答應過的。」「嗯，是答應過。」
2. 否定副詞位於句首時
在正式文體中，never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意義的副詞若位於句首，則其後要用部分倒裝：
I shall never forgive him. / Never shall I forgive him. 我永遠不會寬恕他。
He seldom goes out for dinner. / Seldom does he go out for dinner. 他很少出去吃飯。
She hardly has time to listen to music. / Hardly does she have time to listen to music. 她幾乎沒時間聽音樂。
He little realizes how important this meeting is. / Little does he realize how important this meeting is. 他不甚明白這個會議的重要性。
We had no sooner reached the airport than the plane took off. / No sooner had we reached the airport than the plane took off. 我們剛到機場,飛機就起飛了。
【注意】
(1) 對於not…until句型，當not until…位於句首時，其後的主句要用倒裝語序：
He didn’t leave the room until the rain stopped. / Not until the rain stopped did he leave the room. 雨停了之後他才離開這房間。
(2) 某些起副詞作用的介詞短語，由於含有否定詞，若位於句首，其後要用部分倒裝：
On no accounts must this switch be touched. 這個開關是絕不能觸摸的。
In [Under] no circumstances will I lend money to him.無論如何我也不會再借錢給他了。
但是，in no time(立即，馬上)位於句首時，其後無需用倒裝語序：
In no time he worked out the problem. 他馬上就算出了那道題。
3.「only+狀語」位於句首時
當一個狀語受副詞only的修飾且置於句首時，其後用部分倒裝語序：
Only then did he realize that he was wrong. 到那時他才意識到他錯了。
Only in this way are you able to do it well. 你只有用這種方法才能把它做好。
Only when he returned home did he realize what had happened. 當他回到家裡時，才知道出了什麼事。
涉及only的倒裝及考題分析
按英語習慣同，當「only+狀語」位於句首時，其後句子要用部分倒裝。如：
Only then did he realize that he was wrong. 到那時他才意識到他錯了。
Only in this way are you able to do it well. 你只有用這種方法才能把它做好。
Only in this way can our honour be saved. 只有這樣，才能保住我們的榮譽。

【典型考題】(答案分別為D, C)
1. Only then _________ how much damage had been caused.
A. she realized B. she had realized
C. had she realized D. did she realize
2. Only after my friend came _________.
A. did the computer repaired B. be repaired the computer
C. was the computer repaired D. the computer was repaired
特別說明：有時命題者不是利用位於句首的「only+狀語」來考查倒裝，而是倒過來，利用給定的倒裝結構來考查對only的選擇。
如下面一題(答案選A)：
_________ by keeping down costs will Power Data hold its advantage over other companies.
A. Only B. Just C. Still D. Yet
4. 由not only…but also引出的倒裝
當句型「not only…but also「中not only 位於句首引出句子時，not only 後的句子通常用部分倒裝形式：
Not only is he a teacher, but he is also a poet. 他不僅是一位教師，而且是一位詩人。
Not only did he speak more correctly, but he spoke more easily. 不僅他講得更正確，也講得更不費勁了。
5. 虛擬條件句的省略與倒裝
當if引導的虛擬條件從句中含有had, were, should等時，如將if省略，則要將had, were, should等移到主語前，構成倒裝句：
Had you come yesterday, you would have seen him.若你昨天來，你就會見到他了。
Should you require anything give me a ring. 如果需要什麼，可以給我打電話。
Were it not for your help, I would still be homeless. 要不是你幫助，我會仍然無家可歸。
【注意】省略if後提前的had不一定是助動詞：
Had I money, I would buy it. 假若我有錢，我就會買它。
6. 「so+adj. / adv.」位於句首時
副詞so後接形容詞或副詞位於句首時，其後用部分倒裝：
So cold was the weather that we had to stay at home. 天氣太冷，我們只好呆在家裡。
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。
So sudden was the attack that we had no time to escape. 襲擊來得非常突然，我們來不及逃跑。
