在以下列副词及连接词开头的句子中，要求用倒装结构。常见的副词有：only，so， here，there，now，often，then，down，out， in，up，hence，thus，well，off，away，twice， gladly，many a time等等。
1、在由only开头的句子中，only后面紧跟用作状语的副词、介词或从句，要求用倒装结构。例如：
1)Only by shouting at the top of his voice_______ .
A)he was able to make himself hear
B)he was able to make himself heard
C)was he able to make himself hear
D)was he able to make himself heard (CET-4，1989.1-50，选D)
2)Only under special circumstances _______ to take make-up tests.
A)are freshmen permitted
B)freshmen are permitted
C)permitted are freshmen
D)are permitted freshmen (CET-4，1997.6-43，选A)
如果only在句首，但是only后面没有紧跟用作状语的副词、介词或从句，则不用倒装结构。
