。你想過這事嗎? (一種想法) 10 mean to doing/to do mean to do 打算、想 mean doing 意味著 I mean to go, but my father would not allow me to. 我想去,但是我父親不肯讓我去。(強調我看見了這個事實) I saw him working in the garden yesterday.(強調我見他正干活這個動作) 昨天我見他正在花園里干活。 10)but作介詞,后接不定式結構時,前面謂語動詞部分若含有do的形式時,but后的不定式要省去to,否則要帶to。 注意區(qū)別用作介詞的to to 有兩種用法: 一為不定式+動詞原形; 一為介詞+名詞/動名詞, to 在下面的用法中是第二種,即to+ 名詞/動名詞: admit to承認,confess to承認,be accustomed to 習慣于,be used to 習慣于, stick to 堅持, turn to開始,著手于, devote oneself to 獻身于, be devoted to 致力于, look forward to 盼望,pay attention to 注意 不定式一般式的用法 一、表示將來 即表示發(fā)生在謂語動作之后的動作。 注:以下用作賓語補足語的不定式省略了to: Who heard him say that? 是誰聽到他這樣說的? Did you notice me pause? 你注沒注意我停頓了一下? 三、表示過去 表示略先于謂語動作的動作。 It’s nice to be sitting here with you. 和你一起坐在這兒真好。 You appear to have travelled quite a lot. 你似乎作過多次旅行。 I hate to have quarreled with her. 我后悔和她吵架了。如: He seems to be saying something. 他似乎在說什么。 二、表示同時 表示與謂語動作同時發(fā)生的動作。 2) Paul doesn39。 I saw him dance. =He was seen to dance. The boss made them work the whole night. =They were made to work the whole night. 4) would rather,had better: 5) Why… / why not…: 6) help 可帶to,也可不帶to, help sb (to) do sth: 7) but和except:but前是動詞do時,后面出現(xiàn)的動詞用不帶to的動詞不定式。 我開始明白真相。 (想了解) I39。 Go on doing the other exercise after you have finished this one. 作完這個練習后,接著做其他的練習 8 be afraid doing/to do be afraid to do 不敢,膽怯去做某事,是主觀上的原因不去做,意為怕; be afraid of doing 擔心出現(xiàn)doing的狀況、結果。 6 try doing/to do try to do 努力,企圖做某事。 典型例題 You were brave enough to raise objections at the meeting. Well, now I regret ___ that. A. to do B. to be doing C. to have done D. having done 答案:D。而不僅僅是爬山動作的終止,所以stop doing 。此處不符合題意。 3)動名詞與不定式語義不同的有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。 2) 如在too前有否定詞,則整個句子用否定詞表達肯定, too 后那個詞表達一種委婉含義,意 為不太。如果道理上通順用of,不通則用for。 Why not +動詞原形表達向某人提出建議 為什么不……? 干嗎不……? 例如: Why not take a holiday? 干嗎不去度假? It39。 2)作結果狀語,表事先沒有預料到的,要放在句子后面。 3) 當不定式作主語的句子中又有一個不定式作表語時,不能用It is… to…的句型 (對)To see is to believe. 百聞不如一見。 b. It39。 4) there be+不定式 believe,expect,intend,like,love,mean,prefer,want,wish,undrstand 例句: a. We didn39。此類動詞還有get,have。 b. There are so many kinds of taperecorders on sale that I can39。 4) 完成進行式: She is known to have been wreaking on the problem for many 。 I hope to see you again. = I hope that I39。不定式的定義 在語法中,[1]是動詞的一種不帶詞形變化從而不指示人稱、數(shù)量、時態(tài)的形式。 He seems to know 。 He seems to be eating 。 3)動詞+疑問詞+ 不定式 decide, know, consider forget, learn, remember, show, understand, see, wonder, hear, find out, explain, tell 例句: a. Please show us how to do that. 請演示給我們如何去做。find后也可帶一個從句。 3) to be +形容詞 Seem,appear,be sai
