it is time 是...的時候了。
這個結構有以下兩種變形形式,所用虛擬語氣形式都一樣:it is high time / it is about time.
這三個結構后面加的句子謂語動詞都用一般過去時來體現(xiàn)虛擬語氣。

這里should表示一種語氣,經(jīng)常被翻譯成“竟然”。
a. 四個動詞:think, believe, expect, suspect.

b. it is a pity, it is a shame 真遺憾,it is strange 真怪
以上三個結構后面加的句子謂語動詞用:should + 動詞原形,should不能省略。
錯綜時態(tài)的虛擬語氣
錯綜時態(tài)的虛擬語氣即指主句和從句在表達是與什么時態(tài)的事實相反上并不一致(比如主句要表達與現(xiàn)在事實相反而從句要表達與過去事實相反),這種情況要采用“對號入座”的方法來處理,即主從句結構分別采用與其表達時態(tài)對應的結構。
