摘要:考點1:情態(tài)動詞基本含義的考查 情態(tài)動詞的基本含義,一直是考查的重要內(nèi)容。 例如: 1. The fire spread through the hotel very quickly but everyone______get out.

    考點1:情態(tài)動詞基本含義的考查
    情態(tài)動詞的基本含義,一直是考查的重要內(nèi)容。
    例如:
    1. The fire spread through the hotel very quickly but everyone______get out.
    A. had to B. would C. was able to D. could
    解析:考查情態(tài)動詞的基本含義。had to:不得不; would:表示意愿或過去常常;could傾向于表示經(jīng)過長期訓(xùn)練而獲得的能力;was able to 表示經(jīng)過努力而能夠做到的事或成功地做了某事。因此,答案是C.
    分析:對情態(tài)動詞基本含義的考查,仍然集中在常用的情態(tài)動詞上。對常用情態(tài)動詞的含義,要掌握的既準(zhǔn)確又要全面,特別是shall, should, can, may 四個常用情態(tài)動詞的含義較多,不易理解,復(fù)習(xí)時應(yīng)當(dāng)引起重視。

    考點2:情態(tài)動詞表示推測的考查
    對情態(tài)動詞表示推測的用法,是高考考查情態(tài)動詞的一個重要方面。
    例如:
    1. Sorry, I'm late. I______have turned off the alarm clock and gone back to sleep again
    A. might B. should C. can D. will
    解析:might have done : (過去)可能做過某事;shouldhave done :本應(yīng)該做某事。根據(jù)本句提供的情境I'm late 表明說話人可能把鬧鐘關(guān)上了。答案是:A.
分析:對表示推測的情態(tài)動詞集中在must, can, could, may, might上,準(zhǔn)確掌握它們使用的場合,是解決問題的關(guān)鍵。Must 用于肯定陳述句,表示肯定推測;can, could用于疑問或否定陳述句,表示可能性推測;may, might用于陳述句,表示可能性推測;用于否定陳述句中,can't (不可能)的語氣比may not(可能不)強(qiáng)。此外,還要注意有對過去和對現(xiàn)在兩種情況的推測,對過去推測用情態(tài)動詞+have done ,對現(xiàn)在推測用情態(tài)動詞+ 動詞原形。

    考點3:情態(tài)動詞表示虛擬的考查
    情態(tài)動詞+have+過去分詞表示與過去事實上相反的情況,也是高考單項選擇題涉及到情態(tài)動詞的一個重要方面。
    1. There was a lot of fun at yesterday's party. You______come, but why didn't you?
    A. must have   B. should   C. need have D. ought to have
    解析:ought to have done 表示本來應(yīng)該做某事而實際沒做,should do 表示現(xiàn)在應(yīng)該做某事,與題中 at yesterday's party 表示的時間不一致。所以選D.
    分析:對情態(tài)動詞表示虛擬'用法,表示與過去事實相反的情況。近幾年,主要側(cè)重should (not)have done 這一句式上,表示本來不該做卻做了或本來該做卻未做的事,在復(fù)習(xí)時,還應(yīng)關(guān)注其它幾種虛擬形式,如need (not)have done 表示本來需要做而未做或本來不需要而做的事等等,以做到有備無患。

    考點4:情態(tài)動詞與助動詞混合考查
    1.Tom ,you didn't come to the party last night?
    —I _____, but I suddenly remembered I had homework to do .
    A. had to B. didn't C. was going to D. wouldn't
    解析:had to:不得不;didn't:沒來;was going to:打算來;wouldn't:不愿來。句意:——湯姆,昨晚你沒來參加舞會嗎?——我本打算來,但我突然記起有作業(yè)要做。But是關(guān)鍵詞,所以答案是:C.

   【答案與解析】
    1. 【解析】選B.It's time you did 為 It's time you thanked Aunt Lucy for her present 之略。按照英語語法,it's time 后從句通常要用過去式。
    2. 【解析】選A.雖然前有虛擬條件句, 后有使用了虛擬語氣的賓語,但 I don't know 卻宜用一般現(xiàn)在時,因為 I don't know 表述的是現(xiàn)在的真實情況,句意為“我要不是有幸遇到你,我真不知(指現(xiàn)在不知)我會做出什么蠢事來”。
    3. 【解析】選B.I'd rather 后接從句時,從句謂語的時態(tài)規(guī)律是:用過去式表示現(xiàn)在或?qū)?,用過去完成式表示過去。
    4. 【解析】選A.we can't get there by tomorrow 為客觀事實,故宜用陳述語氣。
    5. 【解析】選B.第一空填 knew,因為 I wish 后的賓語從句要用虛擬語氣(即用過去式表示現(xiàn)在的想法);第二空要填lives,即用陳述語氣,因為 where he lives 是一個客觀事實,而不是 I wish 的內(nèi)容。
    6. 【解析】選C.It's time… / It's high time… / It's about time… 等后接從句時,從句謂語通常用過去式。
    7. 【解析】選 B.此題涉及錯綜時間虛擬條件句,主句與現(xiàn)在事實相反,條件句與過去事實相反。句意為:要不是在七歲時就迷上了 Melinda Cox 圖書館,我真不能想像我如今會在做什么。
    8. 【解析】8. 選 D.這是otherwise 引出的含蓄虛擬語氣,再根據(jù)前面的 hesitated 可進(jìn)一步知道這是與過去事實相反的虛擬語氣,由此可推知答案選 D.
    9. 【解析】選 C.if only意為“要是……就好了”,其后的句子謂語要用虛擬語氣,同時根據(jù) as the doctor instructed 中的過去時態(tài)可知從句是與過去事實相反,故選 C.
    10. 【解析】選 A.without 引出的介詞短語為一個與現(xiàn)在事實相反的含蓄條件句。【答案】C
