only开头的倒装句

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.

自己电脑里整理的资料，希望能帮得到你。

首先要注意的是:当only强调人，物，代词，名词时不倒装．
还有：否定副词是never,seldom,rarely,little,hardly,scarcely,nowhere,no sooner等在与句首是，句子部分倒装．
至于倒装，前后时态一般相同，就是把助动词（do,does,did,have,has,hadd等）,系动词（am,is,are,was,were等），情态动词（can,could,should,must等）等提前．之后语序不变．
又及，我说的不一定全对，如果你老师讲解的话，还是以老师说的为标准哈

当出现hardly、never、often、seldom、（not）only等否定含义的词放在句首，后面要用到装。固定句型，需要记忆。
Only in this way, can you see him. 只有用这种方法才能见到他。
Only in this way,do you study English well.只有用这种方法你才能学好英语。
