小升初英语语法经典例题：非谓语动词（1）

　　(5) 选D错误：若单独看 All her time is devoted to doing experiments，此句并没有错，但问题是逗号前后两个简单句没有必要的连接方式，所以从整体上看仍不对，假若在后一句的句首加上and或so，则可选D，或将D将中的is 改为 being也可选它。

　　请做以下类似题(答案均选A)：

　　(1) All the preparations for the project ______， we’re ready to start.

　　A. completed B. have been completed

　　C. had been completed D. been completed

　　(2) Such _______ the case， I couldn’t help but______ him.

　　A. being， support B. was， support

　　C. has been， supporting D. is， to support

　　比较以下各题，答案选B，因为句中使用了并列连词and：

　　(1) All the preparations for the project ______， and we’re ready to start.

　　A. completed B. have been completed

　　C. had been completed D. been completed

　　(2) Such _______ the case， I couldn’t help but______ him.

　　A. being， support B. was， support

　　C. has been， supporting D. is， to support

　　4. The purpose of new technologies is to make life easier， ______ it more difficult.

　　A. not make B. not to make

　　C. not making D. do not make

　　【陷阱】容易误选C，受题干中的逗号的影响，认为是现在分词表结果的用法。

　　【分析】其实答案应选B，句中的逗号相当于连词 and 或 but，not to make it more difficult 是对逗号前的不定式 to make life easier 的补充说明。此句的意思是“新技术的目的是为了使生活变得更容易，而不是使生活变得更困难”。两个不定式同时用以说明句子主语 purpose 的内容。请做以下类似试题(答案选B)：

　　The purpose of the scheme is not to help the employers but _____ work for young people.

　　A. provide B. to provide

　　C. providing D. provided

　　5. The murderer was brought in， with his hands ______ behind his back.

　　A. to be tied B. being tied

　　C. tied D. having tied

　　【陷阱】容易误选B。

　　【分析】最佳答案为C。从意义上看，hands 与 tie 的关系应属被动关系，故排除D。在A、B、C三个选项中，选项A比较容易排除，因为不定式表示将来意义，在此与语境不符。现将B和C作一比较：B为现在分词的被动式，它表示两层意义，一是表被动，二是表进行，也就是说his hands being tied 的实际意思是“他的手正在被捆住”，这显然与语境不符。而C为过去分词，它也表示两层意义，一是表被动，二是表示动词的完成或完成后的状态，此句中的 with his hands tied behind his back 可视为手被捆在背后的一种状态。由此可知最佳答案为C。请看下面一题：

　　Anyone ______ trying to take knives on heard flights would be caught by the police.

　　A. finds B. found

　　C. being found D. will find

　　答案选B而不选C，其中的过去分词表示被动和完成。

　　比较下面两题，最佳答案是D不是A，现在分词的被动式表示被动和进行：

　　(1) The court hears about 120 cases a year； visitors are welcome to see a case ______.

　　A. argued B. to be argued

　　C. to be arguing D. being argued

　　(2) The silence of the library was sometimes broken by an occasional cough or by the sound of pages _______.

　　A. turned B. having turned

　　C. to be turned D. being turned

　　6. Remind me _______ the medicine tomorrow.

　　A. of taking B. taking

　　C. to take D. take

　　【陷阱】容易误选A。受 remind sb of (doing) sth 这一常用结构的影响。

　　【分析】最佳答案为C。比较以下三个结构：

　　remind sb of [about] sth = 使某人想起某事

　　remind sb of doing sth = 提醒某人做过某事(暗示动作已发生)

　　remind sb to do sth = 提醒某人去做某事(暗示动作尚未发生)

　　请看两个例句：

　　I reminded him of his promise. 我提醒他做过的诺言。

　　My wife reminded me of seeing that film. 我妻子提醒我曾经看过那部电影。

　　Can you remind me to phone her tomorrow？ 你明天能否提醒我给她打电话？

　　7. Once your business becomes international， _____ constantly will be part of your life.

　　A. you fly B. your flight

　　C. flight D. flying

　　【陷阱】几个干扰项均有可能误选。

　　【分析】最佳答案为D。由于空格后出现了constantly这一副词，这就说明不能选B或C，因为B、C均为名词，不能受副词 constantly 的修饰。A和D均是可能的，因为其中有动词 fly。但若选A，you fly 是一个主谓结构，与其后的谓语 will be 相冲突，所以只能选D，即动名词flying在此用作主语。

　　8. Not only should you get used ______ under difficult conditions but you also you pay more attention ______ your work well.

　　A. to work， to do B. to working， to doing

　　C. to work， to doing D. to working， to do

　　【陷阱】容易误选A，认为两个空白处均应填不定式。

　　【分析】正确答案为B，因为 get used to与pay attention to 这两个结构中的to均为介词，不是不定式符号，故后接动词时要用动名词，不能动词原形。类似地，以下各结构中的 to 也是介词，不是不定式符号，后接动词时也应用动名词，而不是动词原形：

　　look forward to doing sth 盼望做某事

　　be opposed to doing sth 反对做某事

　　object to doing sth反对做某事

　　stick to doing sth 坚持做某事

　　get down to doing sth 开始做某事

　　take to doing sth 喜欢上做某事

　　admit to doing 承认做了某事

　　pay attention to doing sth 注意做某事

　　devote one’s time to doing sth 把某人的时间用于(奉献于)做某事

　　be equal to doing sth 等于做某事，能胜任做某事

　　What do you say to doing sth 你认为做某事怎么样

　　9. Both of my parents insisted _______ a computer for me， but I don’t think it is necessary.

　　A. to buy B. buying

　　C. on buying D. in buying

　　【陷阱】容易误选B，误认为insist后不能接不定式，但可以接动名词。

　　【分析】答案应选C。其实，动词 insist 后既不能接不定式也不能接动名词，因为insist 通常用作不及物动词；若语义上需接宾语，要借助介词 on或upon，即用于 insist on [upon] (doing) sth；但它有时的确也可用作及物动词，不过其宾语通常只能是 that 从句，而不能是普通的名词、代词或动名词。如：

　　He insisted on seeing her home. 他坚持送她回家。

　　I insisted that he (should) stay. 我坚持要他留下。
