only in this way can I do it.
只有这样我才能做好.
注意比较：此句中的情况下才为倒装；
only对“状语”等起下强调才用倒装.
Only I can do it.是个极其简单的句子.
拙见
就是主句之外一类修饰的句子或短语；
Weather permitting, we will go skiting.
Weather permitting,=if weather permitts
为条件状语；
Only in my home can I sleep sound!
in my home为地点状语；
I explane this for you to do you a favor.
(to do you a favor)为目的状语
开头那一句only in this way ……即为方式状语
把这些状语去掉,主句仍是成立的!
故只为修饰、强调的作用!
