全部倒装
谓语全部倒装移动到主语前面。

You will never know the truth. => Never will you know the truth.
He cares little for my words. => Little does he care for my words.
I had no sooner got the invitation than I refused. => No sooner had I got the invitation than I refused.
- only 位于句首

Only in this way can we learn English well.
- 虚拟条件句省略 if
