微英語 - 1000語法細節(jié):虛擬語氣002

2

有時候，虛擬條件句中，結果主句和條件從句的謂語動作若不是同時發(fā)生時，虛擬語氣的形式應作相應的調(diào)整，這種條件句叫錯綜條件句。比如，從句的動作與過去事實相反，而主句的動作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實不符。例如：If I had worked hard at school, I would be an engineer, too./If they had informed us, we would not come here now.

有一種錯綜條件句，其中的從句的動作與現(xiàn)在事實相反，而主句的動作與過去事實不符。如：If he were free today, we would have sent him to Beijing./If he knew her, he would have greeted her.

一般情況下，would rather, had rather, would sooner等之后的賓語從句，常表示與客觀事實不相符的一種愿望，所以要使用虛擬語氣。比如：I'd rather you had seen the film yesterday./I'd rather you were here now.

標簽：句子、形態(tài)　　難度（4）｜用途（5）｜標記（ ）

雖然be動詞有各種時態(tài)，可以隨著人稱變化。但是需要注意，在虛擬語氣的從句中，動詞be的過去時態(tài)一律用were，不用was。比如：If I were you, I would go to look for him.

這里就只能用were，而不是was.

常用詞組--must have done

　　常用詞組"must have done"表示對過去事情的肯定推測，譯成"一定做過某事"，該結構只用于肯定句。比如：It must have rained last night, for the ground is wet.（昨晚一定下雨了，因為地面還是濕的。）注意，它并不表示虛擬語氣。
