【文章內(nèi)容簡(jiǎn)介】 動(dòng)詞原形”。 I insist that she (should) do her work alone. The mander ordered that troops (should) set off at once. 但是 , 如果 suggest作“ 表明、暗示 ”講 , insist作“ 堅(jiān)持說(shuō)、堅(jiān)持認(rèn)為 ”講，則其后的賓語(yǔ)從句中應(yīng)該用陳述語(yǔ)氣。 The smile on his face suggested that he had passed the examination. He insisted that he didn’t tell a lie. 3)用 whether或 if引導(dǎo)的賓語(yǔ) 從 句 whether和 if均可引導(dǎo)動(dòng)詞后的賓語(yǔ)從句，?？苫Q。 但從句中有 or not且 or not緊跟在引導(dǎo)詞后面時(shí)或介詞后的賓語(yǔ)從句中只能用 whether引導(dǎo) 。其它名詞性從句，如：主語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句只用 whether. I don’t know whether / if he will e or not . I don’t know whether or not he will e. Everything depends on whether we have enough money. I don’t care about whether you have money or not. /whether or not you have money . 介詞后的賓語(yǔ)從句一般不用 which和 if引導(dǎo)，要用 whether和 what。 that也很少引導(dǎo)介詞賓語(yǔ)從句，只在 except, but, in等之后才用 。 4)賓語(yǔ)從句中的時(shí)態(tài)呼應(yīng) 賓語(yǔ)從句的謂語(yǔ)動(dòng)詞時(shí)態(tài)受主句謂語(yǔ)動(dòng)詞的影響，如果主句的謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí)從句中的謂語(yǔ)動(dòng)詞可以用各種時(shí)態(tài)； I know that he studies English every day. I know (that) he will study English next year. We all know that he has studied English since 1998. I know that he studied English last term. 如果主句中的謂語(yǔ)動(dòng)詞用了一般過(guò)去時(shí)，則從句中的謂語(yǔ)動(dòng)詞只能用過(guò)去時(shí)的某種形式，如一般過(guò)去時(shí)，過(guò)去進(jìn)行時(shí)，過(guò)去將來(lái)時(shí)等； We believed that he had earned enough money to build a house. The teacher told us that Tom had left us for America． 當(dāng)從句表示的是客觀真理，科學(xué)原理，自然現(xiàn)象，則從句仍用現(xiàn)在時(shí)態(tài)。 The teacher told us that the sun rises in the east. 5)當(dāng)主句是 I/ We think (suppose, expect, believe, guess, imagine) 時(shí)，其后的賓語(yǔ)從句如果是否定形式，常把否定詞 not從從句中轉(zhuǎn)移到主句中成為否定的轉(zhuǎn)移 。 We don’t believe that he will win the game. I don’t think he will do so. doubt用于肯定結(jié)構(gòu)時(shí)，后面用whether/ if 引導(dǎo)名詞性從句；用于否定結(jié)構(gòu)或疑問(wèn)結(jié)構(gòu)時(shí)，后面用 that 引導(dǎo)名詞性從句。 be sure 用于肯定句或疑問(wèn)句時(shí)，后接 that 引導(dǎo)的名詞性從句；用于否定句時(shí)，后接 whether/if 引導(dǎo)的名詞性從句。 連接代詞 whoever， whatever，whichever可引導(dǎo)名詞性從句，相當(dāng)于anyone who, anything that等。它們也可以引導(dǎo)讓步狀語(yǔ)從句，相當(dāng)于 no matter who/ what/ which。 Whoever breaks the law should be punished. 練習(xí)： 1. She is very dear to us. We have been prepared to do ____ it takes to save her life. A. whichever B. however C. whatever D. whoever 2. Could I speak to ____ is in charge of International Sales ? A. who B. what C. whoever D. whatever 3. At first he hated the new job but decided to give himself a few months to see ___ it got any better.
