only引起的短语在从句中作状语时,主谓要倒装,能给些例句和典型讲解吗?
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：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 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.
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.
给你几个相关的考题.
[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.

only位于句首修饰壮语要倒装 ;如
only in this way can you learn english well
是only引起的倒装句,will 是助动词,如果这个句子正过来说就是 I will have a chance of
achieving my dream only then
在句首的only如果后面跟了副词、介词短语或从句等状语，则主句用倒装结构。如only后跟
的是主语，就不用倒装结构了。例如：
Only when the war was over in 1918 was he able to get back to work．
Only in this way can you learn English well．
Only after a bitter struggle was the aim achieved．
Only the teachers are allowed to use the room．（不倒装）
Only five men were hurt in the accident．（不倒装）
注意，only和所修饰的状语如果不在句首，则不倒装。
如：
The boy was helped out only when his father arrived in a hurry．
Only then did he realize the importance of English
只有在那时候他才意识到英语的重要性。
only then ,是过一小会儿的意思，一般用在句首，引导倒装句。
例句Only then did he realize the importance of English．
解析：在句首的only如果后面跟了副词、介词短语或从句等状语，则主句用倒装结构。如only后跟的是主语，就不用倒装结构了。
再比如
Only when the war was over in 1918 was he able to get back to work．(倒装句）
Only five men were hurt in the accident．（不倒装
还有：当only强调人，物，代词，名词时不倒装．而且不能用在否定句子里。
只能讲we needn't go to school only on Sunday.

这个简单，只有把only+状语 放在句首时句子才用部分倒装句的形式，这个状语可以是一个单词如here /there, then 、now，一个介词短语或一个句子，由when/where/how/if/before等从属连词引导的状语句子。如：

Only then(一个单词，那时，...

You can find him only in the library.你只能在图书馆才能找到他。
--Only in the library（介词短语做地点状语） can you find him.
They will stay at home only when it is hot.只有天热时他们才会呆在家里。
Only when it is hot(when引导的时间状语从句) will they stay at home.
还有部分倒装句的变法很简单，和变一般疑问句基本类似。

同时记住only后+状语才倒装，所以：
只有你才会回答这个问题。Only you can answer this question.这个句子不是倒装句，因为only后的you不是状语。
