關於英語語法倒裝句知識點:“only+狀語”類倒裝的歸納

我們先來看一道考題：

Only in this way __________ able to finish the work in time.

A. can you be B. are you C. you can be D. you are

此題應選 B。容易誤選D。至於A，C，這比較容易排除，因為情態動詞 can 不能與 be able to用在同一謂語中。本題之所以要選B而不選D，主要是因為句首用了only in this way 的緣故，按照英語語法規則：only+狀語位於句首，句子通常要用倒裝語序(部分倒裝用一般疑問句形式)：

1. only+副詞位於句首：

Only then did I realize that I was wrong. 只是到了那時我才意識到是我錯了。

Only by shouting was he able to make himself heard. 他只有叫喊才能讓別人聽到他。

The pilot reassured the passengers. Only then did I realize how dangerous the situation had been. 飛機駕駛員要乘客們放心，這時我才明白剛才的情況有多危險。

2. only+介詞短語位於句首：

Only by working hard can you succeed. 只有努力工作你才能成功。
