微英語 - 1000語法細(xì)節(jié):虛擬語氣002

2

有時(shí)候，虛擬條件句中，結(jié)果主句和條件從句的謂語動作若不是同時(shí)發(fā)生時(shí)，虛擬語氣的形式應(yīng)作相應(yīng)的調(diào)整，這種條件句叫錯(cuò)綜條件句。比如，從句的動作與過去事實(shí)相反，而主句的動作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實(shí)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(cuò)綜條件句，其中的從句的動作與現(xiàn)在事實(shí)相反，而主句的動作與過去事實(shí)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(shí)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.

雖然be動詞有各種時(shí)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(shí)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(jié)構(gòu)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?yàn)榈孛孢€是濕的。）注意，它并不表示虛擬語氣。
