??虛擬語氣在四級考試中是一個必考的考點。其中,最??嫉氖撬谫e語從句中的用法。一些表示主觀判斷、推測、建議、命令和要求的動詞通常引起虛擬的賓語從句,此類動詞后的賓語從句中采用should +do(其中 should可以省略)的虛擬語氣形式。該類動詞包括:
??(1)高中詞匯:advise(勸告)、ask(要求)、decide(決定)、insist(堅持)、order(命令)、suggest(建議)等。
??(2)四級??荚~匯:command(命令)、demand(要求)、desire(渴望)、prefer(寧愿)、propose(提議)、recommend(勸告)、require(要求)等。
??(3)其他詞匯:consent(同意)、maintain(主張)、move(提議)、urge(極力主張)、vote(提議)等。
??例句:I recommend that you be diligent if you want to pass the exam.如果你們想考試及格,我勸你們勤奮學習。
??特別提示:在復習時,可以把相似用法歸類記憶。當一個動詞后面的賓語從句中應使用(should)+do的虛擬語氣形式時,則可推理出用法相同的以下一組從句(以動詞advise為例):
??(1)I advise that we stay and wait here.(動詞后的賓語從句)
??(2)It is advised that we stay here.(It is +動詞的過去分詞+that引導的主語從句)
??(3)It is advisable that we stay here.(It is +由該動詞派生的形容詞+that引導的主語從句)
??(4)My advice is that we stay here.(由該動詞轉(zhuǎn)換的名詞后面的表語從句)
??(5)I offered the advice that we stay here.(由該動詞轉(zhuǎn)換的名詞后面的同位語從句)
??(6)I think it advisable that we stay here.(由該動詞轉(zhuǎn)換的形容詞作賓語補足語,it為形式賓語,真正的賓語從句中使用虛擬語氣)
??以上六類從句中謂語動詞都使用了should +do的虛擬語氣形式,其中,should可以省略。
由上類動詞派生的??济~有:advice(忠告)、deciion(決定)、demand(要求)、desire(渴望)、order(命令)、 preference(偏愛)、proposal(建議)、recommendation(勸告)、requirement(要求)、suggestion(建議)等。
??相關的形容詞或過去分詞有:advisable(合理的)、 desired(期望的)、desirable(合乎需要的)、insistent(堅持的)、ordered(命令的)、preferable(更可取的)、proposed(建議的)、required(要求的)、urgent(緊迫的)等。
例句:His proposal is that we turn off TV for half an hour every day.(表語從句)他建議我們每天少看半個小時的電視。
??It is highly desirable that a new president be appointed for this college.(主語從句)急需為這所大學任命一位新校長。
