If She was in charge,she would do things differently.变成省略IF

如果从句里含有should,had,were或其他助动词,则可将从属连词if省去,将助动词。情态动词。be或have放在句首形成部分倒装。
Eg。Were he in your position,he’d have done the same。
Had I had time,I would have done that yesterday。
Should he come tomorrow,I should give him the dictionary。
(1) 错综时间虚拟句
通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的,但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式。P 116,2
Eg。If I were you,I would have taken his advice。(从句指现在,主句指过去)
If I had taken my raincoat with me this morning,I would not be wet now。(从句指过去,主句指现在)。
