the house is to let. 2. 在“be +adj+ to do ”结构中通常用主动形式表示被动意义。 常用于此结构的形容词有hard ,easy, difficult, dangerous, convenient, interesting, impossible, safe, nice, tough, unpleasant, awkward 等 the book is difficult to understand. the place is easy to reach. english is hard to learn. （六） 不定式的否定式。 通常是把否定词not, never 置于不定式之前，即构成not to do, never to do 的形式，注意not和never一定要放在不定式符号to 的前面，而不是其后面。 be careful not to fall. go in quietly so as not to wake the boy. the driver was not to blame for the traffic accident. 注意若不定式为完成式和被动式，否定词应置于整个结构之前。 how foolish i was not to have bought it! the humor of it is not to be absorbed in a hurry. 四： 既可接to do 也可接ing形式的词，但表达意义不同的词如下： gerundinfinitiveforgethell never forget spending so much money on his first computer.dont forget to spend money on the tickets.go ongo on reading the textgo on to read the text.meanyou have forgotten your homework again. that means phoning your mother.i meant to phone your mother, but my mobile didnt work.rememberi remember switching off the lights when i went on holiday.remember to switch off the lights when you go on holiday.stopstop reading the text.stop to read the text.trywhy dont you try running after the dog?i tried to run after the dog, but i常接ing形式的词advise, suggest ,admit, avoid, consider, delay, deny, feel like, finish, imagine, miss, practice, risk, 五 接ing 形式，但需要接宾语再接to do 的有：1.advise they advise walking to town. they advise us to walk to town.2. allow they do not allow smoking here. they do not allow us to smoke here. 3 encourage they encourage doing the test. they encourage us to do the test.4. permit they do not permit smoking here. they do not permit us to smoke here. 注意：recommend suggest they recommend walking to town. they recommend that we walk to town. recommend/suggest to sb 不能用 suggest sb to do sth 动词不定式专题练习【基础训练】1. he seems _ the old lady. a. knowing b. to be knowing c. to know d. to be known2.tom _ when they spoke ill of him.a. happened to be passed b. happened to be passing by c. happened passing by d. happened to passed3. we all hope _ scientists. a. become b. to become c. becoming d. became4. the boy refused _ for climbing the tall tree. a. to pay b. to be paid c. being paid d. paying5. i happened _ the article when he asked me about it. a. having read b. to have read c. to be read d. reading6. _ with him is a great pleasure. a. to talk b. talk c. talked d. to talking7. it is nice _ your voice. a. to hear b. hear c. heard d. to be hearing8. _ is to struggle. a. living b. live c. to live d. to be lived9. her wish is _ a doctor. a. becoming b. become c. to become d. being come10. i was just about _ the office when the phone rang. a. leaving b. leave c. to leave d. to leaving11. i didnt _ it until you had explained how.a. manage to do b. managed to do c. manage to have done d. manage doing12. he found it important _ the situation all over the world. a. study b. to study c. studies d. to be studied13. at last the enemy soldiers had no choice but _ their guns. a. to lay down b. lie down c. laying down d. lay down14. yesterday i did nothing but _ tv. a. watch b. watched c. to watch d. watching15. it had no effect except _ him angry. a. make b. making c. to make d. made16. bob did nothing except _ tennis. a. play b. to play c. playing d. played17. im considering _ his letter. a. to answer b. how answering c. to be answering d. how to answer18. tell us _ next. a. how to do b. what to do c. how do d. what do19we want to know_ to help him when he is in trouble. a.what will do b.what we should do c.how to do d.what will we do20. dont stop trying. youll be sure _ . a. succeed b . succeeding c. of succeeding d. to succeed21. the government calls on us _ our production. a. increased b. increasing c. increase d. to increase22. with his teacher _ he wanted to try it a second time. a. helping b. to help c. help d. helped23. the lady was watched _ her room in silence. a. had left b. left c. leave d. to leave24. im hungry . get me something _. a. eating b. to eat c. to be eaten d. eaten25. his wish ,_ a doctor ,came true. a. coming b. come c. to come d. came26. he loves praise. he is always the first _ and the last _.a. of coming ; of leaving b. comes; leaves c. to come; to leave d. coming; leaving27. at last they found a house _ . a. to leave his things with b. to leave his things in c. leaving his things in d. left his things in28. there is nothing _ . a. to worry b. to worry about c. worry d. worry about29.have you got enough room _all of us ?
