五、only在句首要倒裝的情況

　　Only in this way， can you learn English well.

　　Only after being asked three times did he come to the meeting.

　　如果句子為主從復(fù)合句，則主句倒裝，從句不倒裝

　　Only when he is seriously ill， does he ever stay in bed.

　　六、as， though 引導(dǎo)的倒裝句

　　as / though引導(dǎo)的讓步從句必須將表語(yǔ)或狀語(yǔ)提前 （形容詞， 副詞， 分詞， 實(shí)義動(dòng)詞提前）。

　　注意：

　　1）句首名詞不能帶任何冠詞。

　　2）句首是實(shí)義動(dòng)詞， 其他助動(dòng)詞放在主語(yǔ)后。如果實(shí)義動(dòng)詞有賓語(yǔ)和狀語(yǔ)， 隨實(shí)義動(dòng)詞一起放在主語(yǔ)之前。

　　Try hard as he will， he never seems able to do the work satisfactorily.

　　注意：

　　讓步狀語(yǔ)從句中，有though，although時(shí)，后面的主句不能有but，但是 though 和yet可連用。
