“only+状语”置于句首句子要部分倒装

副词only置于句首， 强调方式状语、 条件状语、 地点状语、 时间状语等状语时， 主句要进行部分倒装。如果被only所强调的状语为状语从句， 该状语从句不倒装， 只对主句进行倒装。例如：

1. “only 副词”位于句首。如：

Only then did I realize that I was wrong. 只是到了那时我才意识到是我错了。

Only then did he realize that he was wrong. 到那时他才意识到他错了

Only then did I understand what she meant. 只有到那时我才明白她的意思。

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。

2. “only+介词短语”位于句首。如：

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

Only in the reading-room can you find him. 你只有在阅览室才能找到他。

Only in a big city was it possible to buy a new wheelchair. 只有在大城市里才能买到新轮椅。

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 in this way can we learn English. 只有这样才能学会英语

Only by shouting was he able to make himself heard.  他只有叫喊才能让别人听到他。

Only on one point do I agree with you. 只有一点，我同意你的说法。

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。

3. “only+状语从句”位于句首。如：

Only when one loses freedom does one know its value. 一个人只有在失去自由后才知道自由的可贵。

Only when we had studied the data again did we realize that there was a mistake. 只有当我们再次研究了这些数据的时候， 我们才意识到出了一个错。//

Only because there were some cancelled bookings did he get some tickets in the end. 一些预订被取消了， 他才得以买到了几张票。

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 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。

注意： 如果放于句首的only所修饰的不是状语时， 该句不用倒装。例如：

Only John can save me. 只有约翰能够救我。

Only some of the children passed the examination. 只有几个孩子通过了考试。

Only a policeman the children saw in the street. 孩子们在街上只看到一个警察。

 

 

 

请看下面一道涉及only的倒装试题：

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

此题应选 B。容易误选D。至于A，C，这比较容易排除，因为情态动词 can 不能与 be able to用在同一谓语中。本题之所以要选B而不选D，主要是因为句首用了only in thisway 的缘故，按照英语语法规则：“only+状语”位于句首，句子通常要用倒装语序(部分倒装——用一般疑问句形式)。如：

 

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

 

 

 

【典型考题】(答案分别为DC)

 

 

_________ by keeping down costs will Power Data hold its advantage over other companies.

A. Only                  B. Just                    

C. Still                     D. Yet

 

 

 

(答案选A)

 

 

　　［考题1］ ____ by keeping down costs will Power Data hold its advantage over other companies. (2006浙江)

　　A. Only B. Just C. Still D. Yet

　

 

 

　［答案］ A

　　［解析］ 放于句首的only修饰方式状语by keeping down costs时， 全句要进行部分倒装， 而just, still, yet都无此用法。

　　［考题2］ Only in this way ____ to make improvements in the operating system. (2003上海春)

　　A. you can hope B. you did hope

　　C. can you hope D. did you hope

　

 

 

　［答案］ C

　　［解析］ only在题干中放于句首并修饰方式状语in this way， 全句应进行部分倒装。又由于该句不是介绍过去的情况而是表述现实的一种状况， 所以不应采用一般过去时， 本题应选C。

　　［考题3］ ____ can you expect to get a rise. (2001北京、 安徽春)

　　A. With hard work 

B. Although work hard

　　C. Only with hard work 

D. Now that he works hard

　

 

 

　［答案］ C

　　［解析］ 题干中句子的结构显然为部分倒装语序， 四个选项中只有C选项修饰方式状语with hard work的only可以引导倒装句， 因此本题应选C。

　　［考题4］ Only when your identity has been checked, ____. (2003上海)

　　A. you are allowed in 

B. you will be allowed in

　　C. will you allow in 

D. will you be allowed in

 

 

 

　　［答案］ D

　　［解析］ 放于句首的only修饰when引导的时间状语从句时， 主句应进行部分倒装(从句中不进行倒装)。

　　［考题5］ Only then ____ how much damage had been caused. (2006陕西)

　　A. she realized B. she had realized

　　C. had she realized D. did she realize

　

 

　［答案］ D

　　［解析］ 放于句首的only修饰时间状语then时， 主句应进行部分倒装， 而且主句中“她意识到……”这一过去的动作对应的是“已导致损失”这一发生得更早的动作， 所以下划线应与后面宾语从句中的过去完成时相呼应， 采用一般过去时的形式， 据此可以分别排除选项A、B和C而选出D。
