2010年12月英語(yǔ)四六級(jí)考試詞匯筆記：第25講

　　it is time 是...的時(shí)候了。

　　這個(gè)結(jié)構(gòu)有以下兩種變形形式，所用虛擬語(yǔ)氣形式都一樣：it is high time / it is about time.

　　這三個(gè)結(jié)構(gòu)后面加的句子謂語(yǔ)動(dòng)詞都用一般過去時(shí)來體現(xiàn)虛擬語(yǔ)氣。

　　注意以下兩種情況下should + 動(dòng)詞原形中should不能省略。

　　這里should表示一種語(yǔ)氣，經(jīng)常被翻譯成“竟然”。

　　a. 四個(gè)動(dòng)詞：think, believe, expect, suspect.

　　它們的否定或者疑問形式后面加句子，句子謂語(yǔ)動(dòng)詞用：should + 動(dòng)詞原形，should不能省略。

　　I don't believe that he should be cheated. 我不相信他也會(huì)被騙。

　　b. it is a pity, it is a shame 真遺憾，it is strange 真怪

　　以上三個(gè)結(jié)構(gòu)后面加的句子謂語(yǔ)動(dòng)詞用：should + 動(dòng)詞原形，should不能省略。

　　錯(cuò)綜時(shí)態(tài)的虛擬語(yǔ)氣

　　錯(cuò)綜時(shí)態(tài)的虛擬語(yǔ)氣即指主句和從句在表達(dá)是與什么時(shí)態(tài)的事實(shí)相反上并不一致(比如主句要表達(dá)與現(xiàn)在事實(shí)相反而從句要表達(dá)與過去事實(shí)相反)，這種情況要采用“對(duì)號(hào)入座”的方法來處理，即主從句結(jié)構(gòu)分別采用與其表達(dá)時(shí)態(tài)對(duì)應(yīng)的結(jié)構(gòu)。
