(泛指玩火)玩火是危险的。 to play with fire will be dangerous. (指某一具体动作)玩火将很危险。 结论： 1）动名词作主语表示一般的、抽象的或习惯性的行为 2）不定式作主语表示具体的、一次性的或特指的动作 【注意】to do 和 doing 会在不同的特定句式中充当主语      it is + adj. + to do (不定式做主语)      it is important to respect people. 但是在以下句型中，主语由doing（动名词）充当。      it is useless/ no use/ no good doing sth.      it is no good arguing with him. he never listens to others. 和他争论没好处，他从不听别人的。 ex.  1. it is no use _________(cry) over spilt milk. (crying)      2. it’s necessary for me ________(know)how to use a computer. (to know)      3. it’s no good __________(worry) about it. (worrying) 2.     不定式和动名词作宾语的区别1）通常跟不定式作宾语的词有：afford, agree, want, wish, hope, refuse, manage, ask, offer, promise, pretend, decide, learn, determine, expert, beg, choose, force, intend attempt, fail, claim, long(v.), plan, prepare, would like(love, prefer), mean, seek等    he asked _____________ to work in tibet. 他请求被派往西藏工作。(to be sent)    he refused _____________the job. 他拒绝接受这个工作。(to accept) 2） 通常跟动名词作宾语的词有： admit, appreciate, avoid, consider, delay, dislike, enjoy, escape, excuse, feel like, finish, forgive, imagine, include, keep, mind, miss, practise, resist, risk, suggest, stand等。    would you mind_______________ the window?  你介意我开窗吗？(my opening) 3）有些动词的后面可用不定式或动名词作宾语，但是意义差别很大。这些词有：forget, remember, regret, mean, stop, try, can’t help, go on等。    ① forget to do sth. 忘记去做某事（还没做） forget doing sth. 忘记做过某事（已经做过了） ② remember to do sth. 记着去做某事（还没做） remember doing sth. 记得做过某事（已经做过了） ③ stop to do sth. 停下来去做另一件事       stop doing sth. 停止正在做的事情 ④ regret to do sth   遗憾要去做某事（一般常用的动词有：say, tell, inform）    regret doing sth   后悔做过某事 （已经做了） ⑤ try to do sth    尽力去做某事           try doing sth.  尝试着去做某事 ⑥ mean to do sth. 打算做某事             mean doing sth.  意味着干某事 ⑦ go on to do sth.  接着干（另一件事）  go on doing sth  接着干（同一件事情） ⑧ like/ prefer to do 喜欢干（指某一次具体的行动）    like/ prefer doing 喜欢干（指经常性的，习惯性的动作） ⑨ can’t help to do sth   不能帮忙做某事    can’t help doing sth.  情不自禁地做某事   i remember____________  the lights in the classroom. 我记得关上教室里的灯了。(turning off)   please remember __________ the lights when you leave the classroom.   你离开教室时，记得关灯。(to turn off)   we regret _________ the farm. 我们后悔卖掉了农场。(selling)   i regret_________ you that your father is ill. 很遗憾告诉你，你爸爸病了。(to tell)   i usually prefer __________ to singing, but today i prefer to _______.( dancing, sing) 我平时喜欢跳舞胜过唱歌，但今天我想唱歌。    4）在allow, advise, forbid, permit等动词后直接跟动名词作宾语，但如果后面有名词或代词作宾语，则宾语后用不带to的不定式作宾语补足语。      we don’t allow __________ here. 在这儿我们不允许吸烟。(smoking)      we don’t allow students___________. 我们不允许学生吸烟。(to smoke)    5）need, want, deserve, require +动名词表被动意义，相当于使用不定式。       these flowers need ___________.这些花儿需要浇水了。 = these flowers need ____________. ( watering; to be watered)       they deserved___________. 他们值得表扬。 = they deserved______________. ( praising ; to be praised) 3.     不定式、现在分词、过去分词和动名词做作定语的区别12341）现在分词和动名词作定语时的区别    现在分词作定语与所修饰中心词存在着逻辑上的主谓关系，表示动作的主动进行；而动名词作定语表示所修饰中心词的用途或内容，与所修饰词之间不存在逻辑上的主谓关系。    he uses a walking stick to help keep the balance. 他用一根拐杖来保持平衡。（动名词）    the boy standing over there is my brother. 站在那儿的男孩子是我弟弟。（现在分词） 2）现在分词，过去分词和不定式作定语时的区别    现在分词和被修饰词之间形成主动关系，表示正在进行；过去分词和被修饰词之间形成被动关系，表示已完成；不定式有主动也有被动，作定语表示该动作尚未发生，当名词前有first, last, second, next, only等词时，后置定语常用不定式。    the building _______________（build）next year will be a new school.    the building ___________________ (build) now will be a new school.    the building _________________ (build) last year is a new school now.    this is the first school ___________________ (build) in this area.    （to be built; being built; built; to be built）3）如果不定式所修饰名词是不定式动作承受者，不定式可用主动式也可用被动式，但其含义有所不同。have you got anything to send? 你有什么东西要寄吗？(不定式to send的动作执行者是you）
have you got anything to be sent? 你有什么东西要我（或别人）寄的吗？（不定式to be sent的动作执行者是已被省略的me或somebody else）ex. 1 i have some letters __________ (write).   2. the man __________ (perform) on the stage is a famous comedian.   3. john took many photos of leaves ________ (fall) on the ground.   4. in 1975, george burns acted in a film ________ (call) “the sunshine boys”   5. the underground system __________ (build) in the city will be open next year.   6. tom is often the first one __________ (arrive) at school.   (1. to write   2. performing  3.fallen  4.called    5.being built   6.to arrive) 4.     不定式、现在分词和过去分词作宾语补足语的区别表示感觉的感官动词feel, hear, notice, listen to, see, observe, smell, watch等和表示“致使，让”的使役动词have, leave等词后, 可跟不带to的不定式和分词作宾补。不定式表示事情的全过程，说明某事已发生；用现在分词表示说明动作正在进行，还未结束；用过去分词表示被动和完成。 --do you hear someone knocking at the door? 你听到有人敲门吗？（正在敲） --yes, i did. i heard him knock three times. 是的，我听他敲了三次了。（已敲过了） i found him lying on the ground. 我发现他在地上躺着。（正躺着） he found his wallet stolen. 他发现他的钱包被偷了。 he had his house painted last summer. 去年夏天他让人把房子粉刷了一下。 he went out the room and left the door unlocked. 他出去了，门没锁。 【相关练习】 1. the way my father thought of          enough money was to sell the horse and the house.1234a. getting           b. to get            c. got             d. to getting2. --i’d like to learn more about the doha asian games.--better try       the cctv website, and you are likely       the information in no time.a．to visit; to get                      b．to visit; getting    c．visiting; to get     d．visiting; getting3. don"t be discouraged. _____ things as they are and you will enjoy every day of your life.a. taking        b. to take        c. take           d. taken4. i really regret ________a lie to you, but at that time, i had no choice but________.a．to tell, do so      b．telling, to do so            c．tell, to do so d．telling, do so5. michael put up a picture of yao ming beside the bed to keep himself _____ of his own dreams.a. reminding             b. to remind               c. reminded    d. remind 6. the news he looked forward to        .a. came at last      b. coming at least   c. coming last   d. have come recently7. the largest collection, ______in england, was one of about 200 000 silver pennies.a. to be found        b. has found          c. being found         d. ever found
