    「評析」
    與以上兩種虛擬語氣句式不同,這里虛擬語氣中時態(tài)的變化比較少,主要依據(jù)所處的句型??忌枰氖橇私庠谀男┣闆r下用這種句式,測試中考生只需從四個選項中辨認(rèn)答案即可。該部分所包含的句型有:
    ① 表示"命令""建議"或"要求"的動詞后面的賓語從句中用should + 原形動詞,should可以省略。常用于該句型的動詞有direct, order, command, require, ask, request, demand, insist, suggest, recommend, advise等。
    這里句型的考題中,一般都會有would, must等干擾項,正確選項以省略should者居多,如1)和2)。
    1)The doctor advised that Mr.Malan _____ an operation right away so as to save his life.(1998.6)
    A.had
    B.was going to
    C.have
    D.would have
    答案:C
    2)His mother insisted that he _____ the coat when going out.(1999.6)
    A.put on
    B.puts on
    C.to put
    D.putting on
    答案:A
    并且常是not do something, 或be的形,尤其是 not be done的形式。如:
    Mike's uncle insists ____ in this hotel.
    A.staying not
    B.not to stay
    C.that he would not stay
    D.that he not stay
    答案:D
    It is recommended that the project _____ until all the preparations have been made.
    A.is not started
    B.will not be started
    C.not be started
    D.is not to be started
    答案:C
    As Commander-in-Chief of the armed forces, I have directed that all measures ____ for our defense.
    A.had been taken
    B.would be taken
    C.be taken
    D.to be taken
    答案:C
    另外這類考題還常借助于動詞本身的句法結(jié)構(gòu)設(shè)干擾項。如insist后可接doing something, being done或 on doing something的結(jié)構(gòu),suggest后也可接動名詞。
    注意: 如suggest, insist不表示"建議" 或"堅持要某人做某事時",即它們用于其本意"暗示、表明"、"堅持認(rèn)為"時,賓語從句用陳述語氣。
    (錯)You pale face suggests that you (should)be ill.
    (對)Your pale face suggests that you are ill.
    ② 表示"命令""建議"或"要求"的名詞后面的同位語或表語從句中同樣是用should + 原形動詞,should可以省略。
    與上面一條相同,表示這些概念的名詞如suggestion, advice, order, proposal等后面的that從句中虛擬語氣使用規(guī)則相同,如6)中都是that引導(dǎo)的表語從句中使用should + 原形動詞,should省略的結(jié)構(gòu)。
    6)The general's command is that the soldiers ____ their fort and carry out more important tasks.(2002.6)
    A.would leave
    B.leave
    C.left
    D.have left
    答案:B
    再如:
    We are all for your proposal that the discussion ____.
    A.be put off
    B.was put off
    C.should put off
    D.is to be out off
    答案:A
    The suggestion that the mayor ________the prizes was accepted by everyone.
    A.would present
    B.present
    C.presents
    D.ought to present
    答案:B
    ③ It is + 表示"重要,有必要,吃驚,難以相信"的名詞或形容詞,或表示"命令""建議""要求"的過去分詞 + that 從句中用should + 原形動詞,should可以省略。
    這一句型可分解為
    It is important/necessary/vital/advisable/essential ……that … (should)
    It is strange/surprising/unbelievable … that … (should)
    It is suggested/requested/recommended … that … (should)…
    這些句型一律使用should + 原形動詞的結(jié)構(gòu),should可以省略,如4)、9)題
    4)It is desirable that he ______ .(2000.6)
    A.gives up trying
    B.give up trying
    C.would give up trying
    D.is going to give up trying
    答案:B
    9)It's vital that enough money ______ collected to get the project started.

    再如:

    答案:D
    It is recommended that the project _____ until all the preparations have been made.
    A.is not started
    B.will not be started
    C.not be started
    D.is not to be started
    答案:C
    ④ wish
    wish 后面的從句時態(tài)可以有以下幾種情況
    表示與現(xiàn)在事實相反用一般過去時:
    How I wish I had a memory as good as yours.
    表示與現(xiàn)在正在進(jìn)行的事情相反可用過去進(jìn)行時,如:
    Sometimes I wish I ____ in a different time and a different place.(2000.1)
    A.be living
    B.were living
    C.would live
    D.would have lived
    答案:B
    表示與過去事實相反的情況用過去完成時,也可以用could have done 的形式,如3)。
    I wish I ____ longer this morning, but I had to get up and come to class.
    A.could have slept
    B.slept
    C.might have slept
    D.have slept
    答案:A
    由于might表示"也許",與這里的意思不合,只能用A.
    表示將來不可能實現(xiàn)的情況用would/might + 原形動詞。
    How I wish you would be able to come here for another visit.
    ⑤ If only 表示愿望時與wish用法相同。再如:
    If only that photograph weren't missing.
    If only the letter had arrived in time.
    ⑥ would rather
    該句型中多用相當(dāng)于過去式的形式。如果表示與過去事實相反的情況用過去完成時,否則用一般過去時。在如以下各題:

    A.had not worked

    該句型中一般用一般過去時,如8),再如:

    A.realized
    B.have realized
    C.realize

    答案:A
    (四)狀語從句中的虛擬語氣
    狀語從句中的虛擬語氣主要指as if/though從句中的虛擬語氣,首先請同學(xué)們做一下下面三道題:
    1)He walked past the pole and soldiers as if they ______.
    A.didn't exist
    B.don't exist
    C.hadn't existed
    D.were not existing
    2)He operates the new computer as if he _____ special training in it.
    A.has received
    B.had received
    C.would receive
    D.received
    3)They talked in such an uneasy manner as if something terrible ______soon.
    A.had happened
    B.happened
    C.would happen
    D.has happened
    「答案」ABC
    「評析」
    謂語動詞要求使用虛擬語氣的狀語從句一般是由as if/as though引導(dǎo)。該從句中時態(tài)的選擇原則是:
    ① 如果從句中謂語動詞與主句謂語動詞同時進(jìn)行,用過去進(jìn)行時;
    ② 如果從句中謂語動詞表示與主句謂語動詞同時存在的狀態(tài),用一般過去時,如1)。
    1)He walked past the pole and soldiers as if they ______.
    A.didn't exist
    B.don't exist
    C.hadn't existed
    D.were not existing
    答案:A
    ③ 如果從句中謂語動詞表示先于主句謂語動詞的動作或狀態(tài),用過去完成時,如2)。
    2)He operates the new computer as if he _____ special training in it.
    A.has received
    B.had received
    C.would receive
    D.received
    答案:B
    ④ 如果從句中謂語動詞后于主句謂語動詞發(fā)生,用would/might + 原形動詞。
    3)They talked in such an uneasy manner as if something terrible ______soon.
    A.had happened
    B.happened
    C.would happen
    D.has happened
    答案:C
