10. If only引出的從句
If only引出的從句用以表達(dá)感嘆性的愿望,常譯為“要是…就好了”。If only從句經(jīng)常省略結(jié)果主句,且主要用在虛擬語氣中,即從句的謂語動(dòng)詞用一般過去時(shí)表示現(xiàn)在或?qū)聿豢赡軐?shí)現(xiàn)的愿望,或用過去完成時(shí)表示過去沒有實(shí)現(xiàn)的愿望。
If only the rain would stop.

Note: if only引出的句子偶爾也可使用陳述語氣,但考生須注意的是,在各類測試中一般都以用虛擬語氣為正確答案。
11. would rather(that)引出的從句
would rather意為“寧愿”,接從句時(shí)常省略關(guān)系代詞that。would rather后的從句要用虛擬語氣,即從句謂語動(dòng)詞用一般過去時(shí)表示現(xiàn)在或?qū)淼脑竿?,用過去完成時(shí)表示與過去事實(shí)相反的愿望。

I’d rather you hadn’t told me about it.
12. It is (about/high) time (that) 句型
該句型表示“(早)該做…”,其后的定語從句中的謂語動(dòng)詞要用虛擬語氣表示。在測試中從句的謂語動(dòng)詞用一般過去時(shí)。
It is time that we went to bed.
It is high time that somebody taught you to behave yourself.
13. 表示猜測的幾種不同的方法及意義
一些情態(tài)動(dòng)詞與動(dòng)詞的完成式連用能夠表示對(duì)過去情況的猜測或者未實(shí)現(xiàn)的可能性。

I could have killed her. It was a narrow escape.
2) may (might) have + 過去分詞
A. 表示對(duì)過去情況的推測,意為,“可能已做某事”。
He may have heard the news.
I might have come to a wrong conclusion.
B. 表示一種未實(shí)現(xiàn)的可能性,即本可以做某事,而實(shí)際上并沒有做,有時(shí)含有抱怨的口吻。
It was a narrow escape. You might have killed yourself.
A lot of men died who might have been saved.
3) must have + 過去分詞
