【文章內(nèi)容簡(jiǎn)介】 nd as to tell me the time? 勞駕，現(xiàn)在幾點(diǎn)了。 Why not +動(dòng)詞原形表達(dá)向某人提出建議 為什么不……? 干嗎不……? 例如： Why not take a holiday? 干嗎不去度假? It39。s for It39。s of sb. 1）for sb. 常用于表示事物的特征特點(diǎn)，表示客觀形式的形容詞，如easy, hard, difficult, interesting, impossible等： It39。s very hard for him to study two languages. 對(duì)他來(lái)說(shuō)學(xué)兩門外語(yǔ)是很難的。 2）of sb的句型一般用表示人物的性格，品德，表示主觀感情或態(tài)度的形容詞，如good, kind, nice, clever, foolish, right。 It39。s very nice of you to help me. 你來(lái)幫助我，你真是太好了。 for 與of 的辨別方法： 用介詞后面的代詞作主語(yǔ)，用介詞前邊的形容詞作表語(yǔ)，造個(gè)句子。如果道理上通順用of，不通則用for。如： You are nice. (通順，所以應(yīng)用of)。 He is hard. (人是困難的，不通，因此應(yīng)用for。) 不定式的特殊句型too…to… 1）too…to 太…以至于… He is too excited to speak. 他太激動(dòng)了，說(shuō)不出話來(lái)。 Can I help you ? 需要我?guī)兔? Well, I39。m afraid the box is too heavy for you to carry it, but thank you all the same. 不用了。這箱子太重，恐怕你搬不動(dòng)。謝謝您。 2) 如在too前有否定詞，則整個(gè)句子用否定詞表達(dá)肯定， too 后那個(gè)詞表達(dá)一種委婉含義，意 為不太。 It39。s never too late to mend. (諺語(yǔ)) 改過(guò)不嫌晚。（亡羊補(bǔ)牢，為時(shí)不晚） 3) 當(dāng)too 前面有only, all, but時(shí)，意思是：非?！?等于very。 I39。m only too pleased to be able to help you. 我非常高興能幫助你。 He was but too eager to get home. 他非常想回家。1） 動(dòng)名詞與不定式的區(qū)別： 動(dòng)名詞表達(dá)的是： 狀態(tài)，性質(zhì)，心境，抽象，經(jīng)常性，已發(fā)生的 不定式表達(dá)的是： 目的，結(jié)果，原因，具體，一次性，將發(fā)生的 2）接不定式或動(dòng)名詞，意義相同。 3）動(dòng)名詞與不定式語(yǔ)義不同的有11 組： 1 stop to do stop doing 2 forget to do forget doing 3 remember to do remember doing 4 regret to do regret doing 5 cease to do cease doing 6 try to do try doing 7 go on to do go on doing 8 afraid to do afraid doing 9 interested to do interested doing 10 mean to do mean doing 11 begin/ start to do begin/ start doing 1 forget doing/to do forget to do 忘記要去做某事。 (未做) forget doing 忘記做過(guò)某事?！?已做) The light in the office is stil on. He forgot to turn it off. 辦公室的燈還在亮著，它忘記關(guān)了。(沒(méi)有做關(guān)燈的動(dòng)作) He forgot turning the light off. 他忘記他已經(jīng)關(guān)了燈了?！? 已做過(guò)關(guān)燈的動(dòng)作) Don39。t forget to e tomorrow. 別忘了明天來(lái)。 (to e動(dòng)作未做) 典型例題 The light in the office is still on. Oh，I forgot___. A. turning it off B. turn it off C. to turn it off D. having turned it off 答案：C。由the light is still on 可知燈亮著，即關(guān)燈的動(dòng)作沒(méi)有發(fā)生，因此用forget to do sth. 而forget doing sth表示燈已經(jīng)關(guān)上了，而自己忘記了這一事實(shí)。此處不符合題意。 2 stop doing/to do stop to do 停止，中斷做某事后去做另一件事。 stop doing 停止做某事。 They stop to smoke a cigarette. 他們停下來(lái)，抽了根煙。 I must stop smoking.. 我必須戒煙了。 典型例題 She reached the top of the hill and stopped ___ on a big rock by the side of the path. A. to have rested B. resting C. to rest D. rest 答案：C。由題意可知，她到了山頂，停下來(lái)在一個(gè)路邊的大石頭上休息。因此，應(yīng)選擇stop to do sth. 停下來(lái)去做另一件事。而不僅僅是爬山動(dòng)作的終止，所以stop doing 。 3 remember doing/to do remember to do 記得去做某事 (未做) remember doing 記得做過(guò)某事 (已做) Remember to go to the post office after school. 記著放學(xué)后去趟郵局。 Don39。t you remember seeing the man before? 你不記得以前見(jiàn)過(guò)那個(gè)人嗎? 4 regret doing/to do regret to do 對(duì)要做的事遺憾?！?未做) regret doing 對(duì)做過(guò)的事遺憾、后悔?！?已做) I regret to have to do this, but I have no choice. 我很遺憾必須這樣去做，我實(shí)在沒(méi)有辦法。 I don39。t regret telling her what I thought. 我不為告訴她我的想法而后悔。 典型例題 You were brave enough to raise objections at the meeting.
