A.worth　B.worthy　C.worth-while　D.worth while C. 由worth的用法可知，此句只适合词组be worth-while to do sth.。因此选C。 动词不定式 1 不定式作宾语 1) 动词+ 不定式 afford　 aim　　 appear　　agree　 arrange　　ask　　　be　　　 decide　bother　　care　　choose　　 come　　　 dare　　 demand　desire　　determine　　　　 expect　　　elect　　endeavor　　　　　hope　　　　　　　fail　 happen　 help　　hesitate　learn　 long　　　mean　　 manage　 offer　 ought

on the street.　　　　　　　 　　 父亲不让我们在街上玩耍。 　 b.　We believe him to be guilty. 　　 我们相信他是有罪的。 Find 的特殊用法： 　　Find 后可用分词做宾补，或先加形式宾语，再加形容词，最后加带to 的动词不定式。find后也可带一个从句。此类动词还有get，have。 　　　I found him lying on the ground. 　　　I found it important to learn. 　　　I found that to learn English is important. 典型例题: 　　The next morning she found the man ___ in bed，dead.　 　 A. lying　 B. lie　 C. lay　 D. laying　　 答案：A.find的宾语后面，用分词或分词短语，起宾语补足语作用。现在分词表达主动，也表达正在进行，过去分词表达被动。 2) to + be 的不定式结构，作补语的动词。 Acknowledge,　　believe,　consider,　　think,　declare(声称),　discover, fancy(设想),　feel　　 find,　guess,　 judge,　　imagine,　　　know,　 prove,　　　　　see(理解), show,　　　　suppose,　　　　 take(以为),　　 understand 　　 We consider Tom to be one of the best students in our class. 　　 我们认为汤姆是班上最好的学生之一。 典型例题 　　 Charles Babbage

此句只说明发明这一个事实，不定式后用原形即可。而C为现在完成时，发明为点动词一般不用完成时，且此处也不强调对现在的影响，因此不选C。 3) to be +形容词 Seem,　　　　 appear,　　　be said,　　be supposed,　 be believed,　be thought,　be known,　 be reported,　hope, wish,　 desire,　　　want,　　　 plan,　 expect,　　　 mean… 　The book is believed to be uninteresting. 　人们认为这本书没什么意思。 4)　there be+不定式 believe, expect, intend, like, love, mean, prefer, want, wish, undrstand 　We didn't

.　玛丽把他当作自己的父亲。 3 不定式主语 1） It's easy (for me) to do that.我做这事太容易了 easy,　difficult,　 hard,　 important,　 possible,　 impossible,　comfortable,　 necessary,　 better;　　 the first,　 the next,　　　the last,　　the

seemed selfish of him not to give them anything.　他不给他们任何东西，这显得太自私了。 注意：1) 其他系动词如，look，appear等也可用于此句型 　　　2) 不定式作为句子成分时，动词用单数形式。 　　　3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型 　　　　(对)To see is to believe.　百闻不如一见。 　　　　(错)It is to believe to see. 4 It's for sb.和 It's of sb. 1）for sb. 常用于表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult,　 interesting, impossible等： 　　 It's very hard for him to study two languages. 对他来说学两门外语是很难的。 2）of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。 　　 It's very nice of you to help me. 你来帮助我，你真是太好了。 　 for 与of 的辨别方法： 　　用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如： 　　 You are nice.　(通顺，所以应用of)。 　　 He is hard.　(人是困难的，不通，因此应用for。) 5 不定式作表语 　不定式可放在be动词后面，形成表语。例如： 　　 My work is to clean the room every day. 　　 His dream is to be a doctor. 6 不定式作定语 　 不定式做定语通常要放在被修饰的词后。例如： 　　　I have a lot of work to do.　 　　　So he made some candles to give light. 7 不定式作状语 1）目的状语　 To… only to (仅仅为了),　in order to,　so as

be sat on 答案：B.　如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 8 用作介词的to 　　to 有两种用法： 一为不定式+动词原形； 一为介词+名词/动名词, to 在下面的用法中是第二种，即to+ 名词/动名词： admit to承认，　　　　　　　confess to承认， be accustomed to 习惯于，　 be used to 习惯于， stick to 坚持，　　　　　　 turn to开始，着手于， devote oneself to 献身于，　be devoted to 致力于， look forward to 盼望，　　　pay attention to 注意 9 省to 的动词不定式 1） 情态动词 ( 除ought 外，ought to)： 2） 使役动词 let, have, make： 3） 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补，省略to。 　 注意：在被动语态中则to 不能省掉。 　 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 可带to，也可不带to, help sb (to) do sth： 7） but和except：but前是动词do时，后面出现的动词用不带to的动词不定式。 8） 由and, or和than连接的两个不定式，第二个to 可以省去： 9） 通常在discover, imagine, suppose, think, understand等词后，可以省去to be：　 　　 He is supposed (to be) nice.　他应该是个好人。 举例： 　　 He wants to move to France and marry the girl. He wants to do nothing but go out. 比较：　 He wants to do nothing but go out. 　　　　 He wants to believe anything but to take the medicine. 典型例题 1) ---- I usually go there by train.　 　 ---- Why not ___ by boat for a change?　 　　A. to try going　 B.　trying to go　 C.　to try and go　 D.　try going　　 　　答案：D. why not 后面接不带to 的不定式，因此选D。 2） Paul doesn't have to be made ___.

It starts raining. 　　I'm considering how to go(where to go, what to do). I considered emplying Mr.Wang but 　　decided that Mr.Chen was more suited 　　to the job. 　　4. 在remember,forget等词后，如果跟-ING分词，表示-ING分词的动作发生在主要谓语之前；如果跟不定式则表示不定式的动作发生在主要谓语动作之后 　　I remember telling her that last night. ("告 　　诉"发生在"记得"之前) He remembered to tell her that when she 　　came back. ("记得"发生在"告诉"之前) 　　I'm sorry I forgot to give you the message. (主 　　语动词表示的动作"忘记"发生在不定式表 　　示的动作"给带口信"之前) Why! I have such a bad memory. I forgot 　　giving the message last night. (-ING分词 　　表示的动作"给带口信"发生在谓语动词表 　　示的动作"忘记"之前) 　　5. stop, go on和leave off之后跟接动词不定式和-ING分词所表达的意义有所不同 　　They stopped (talking) to work. ［停下(其他动作)来工作］ 　　They stopped working. ［停下工作(来干其他动作)］ 　　Workers went on discussing the problem. ［工人继续讨论这一问题］ 　　Workers went on to discuss the problem.［工人们停下来其他事，继续讨论这一问题］ 　　He left off writing.［他停下写作(去干其他事)］ 　　He left off to write.［他停下(其他事)来写作］ 　　6. … used to后跟不定式和-ING分词，后跟不定式有两种情况：一种是used to是固定用法表示"过去经常干……"；另外一种情况是use的被动词态"be used"后跟不定式；后跟-ING分词的情况有一种，那就是当used to中的used是形容词时，to后跟名词或-ING分词 　　7) When he was in the plastic plant, he together with the workers. 　　［A］ has worked ［B］ had worked ［C］ had been worked ［D］ used to work 　　8) You will soon this climate and then the changes in temperature will not affect you. 　　［A］ get used to 　　［B］ get to 　　［C］ get over 　　［D］ get on with 　　9) Mr. Anderson used to jogging ［A］ in the crisp morning ［B］ air during ［C］ the winter months ［D］ , but now he has stopped. 　　7. 一般情况下，for后边跟接there to be,而of后边则跟接there being 　　10) It is fairly common in Africa for there an ensemble of expert musicians surrounded by others who join in by clapping, singing, or somehow adding to the totality of musical sound. 　　［A］ to be ［B］ being ［C］ to have been ［D］ having been 　　8. be＋形容词后面要跟动词不定式作状语，而不用-ING 　　It is very difficult to manage the company. 　　二、-ING分词与-ED分词的区别 　　虽然在语法功能上，-ED分词在句子中所能承担的成分基本与-ING分词相同，但在意义上两者有差别：-ING分词表示主动的意义，而-ED分词则表示被动的意义；-ING分词表示一般性的或正在进行的动作，而-ED分词则表示已经完成和被动的动作。在表现形式上，-ING分词有"一般式"和"完成式"与"主动式"和"被动式"之分；而-ED分词只有一种形式。下边我们分析-ING分词与-ED分词在语法功用上的区别。 　　1. 作表语时，-ING分词表示主语所具有的特征而-ED分词表示主语所处的状态 　　The book is quite interesting. I am insteredted in the book very much. 　　The play is more exciting than any I have 　　ever seen. That piece of land lay deserted. 　　2. 作状语时-ING分词表示主语正在进行的另一动作而-ED分词则表示主语发生动作的背景或情况 11) In his movies，W. C.
