按英语习惯同，当“only+状语”位于句首时，其后句子要用部分倒装。如：
Only then did he realize that he was wrong.
到那时他才意识到他错了。
Only in this way are you able to do it well.
你只有用这种方法才能把它做好。
Only in this way can our honour be saved.
只有这样，才能保住我们的荣誉。
Only then did I understand what she meant.
只有到那时我才明白她的意思。
Only after her death was I able to appreciate her.
只有到她死后我才认识到她的价值。
Only when he returned home did he realize what had happened.
当他回到家里时,才知道出了什么事。
Only in this way can we learn English.
只有这样才能学会英语。
The pilot reassured the passengers. Only then did I realize how dangerous the situation had been.
飞机驾驶员要乘客们放心，这时我才明白刚才的情况有多危险。
Only by shouting was he able to make himself heard.
他只有叫喊才能让别人听到他。
Only when we landed did we see how badly the plane had been damaged.
我们只是在着陆之后才看到飞机损坏的严重程度。
Only on one point do I agree with you.
只有一点，我同意你的说法。
【典型考题】(答案分别为DC)

A. she realized B. she had realized
C. had she realized D. did she realize
2. Only after my friend came _________.

特别说明：有时命题者不是利用位于句首的“only+状语”来考查倒装，而是倒过来 ，利用给定的倒装结构来考查对only的选择。如下面一题(答案选A)：
_________ by keeping down costs will Power Data hold its advantage over other companies.
A. Only B. Just C. Still D. Yet
