 有提示词类必考点(二)——非谓语动词


技法一
了解句法功能，判断非谓语形式

分析句子所缺少的成分，以便选择恰当的形式。非谓语动词在句中可作主语、表语、宾语、定语、补语。理解非谓语动词的句法功能是判断非谓语形式的关键。
(一)作目的状语时用不定式，且只能用不定式的一般式
1．(2018·全国卷Ⅰ)You don’t have to run fast or for long (see) the benefit.
解析：to see　句意：你不必跑得很快，也不必跑很长时间就见到效果。不定式短语to see作目的状语。
2．(2018·全国卷Ⅱ)The government encourages farmers to grow corn instead of rice (improve) water quality.
解析：to improve　句意：政府鼓励农民种植玉米而不是水稻来改善水质。故用不定式to improve作目的状语。
3．(2017·6月浙江高考)Sixteen years earlier, Pahlsson had removed the diamond ring (cook) a meal.
解析：to cook　根据语境可知，Pahlsson摘掉钻戒的目的是做饭，此处应用动词不定式作目的状语，故填to cook。
(二)作伴随状语、方式状语和结果状语时用现在分词
4．(2018·江苏高考改编)Around 13,500 new jobs were created during the period, (exceed) the expected number of 12,000 held by market analysts.
解析：exceeding　句意：在这段时期大约创造了13 500个新工作，超过了市场分析家认为的12 000 的预期数字。分析句子结构可知，were created是谓语，空处应用非谓语动词形式。再结合语境可知，此处应用现在分词短语作结果状语，表示自然而然的结果。
5．(2016·全国卷Ⅲ)People probably cooked their food in large pots, (use) twigs (树枝) to remove it.
解析：using　逻辑主语people 与use之间为主动关系，故用现在分词using作方式状语。
6．Finally I refused to attend classes， (shut) myself in my room for hours.
解析：shutting　句意：最后，我拒绝上课，把自己关在房间几个小时。refused和shut之间没有并列连词，故可判断设空处应为非谓语动词作状语。主语I与shut之间为逻辑上的主动关系，且shut与refused同时发生，故设空处表示伴随，故填shutting。注意：shut的现在分词形式需要双写“t”。
7．(2018·浙江宁波九校联考)I like staying up late (watch) TV, surfing the Internet or doing something I’m fond of.
解析：watching　逻辑主语I与watch之间为主动关系，表示伴随状态，故填现在分词watching。

解析：leaving　句意：更糟糕的是，他的妻子离他而去，留下他自己和6岁的小儿子。设空处作结果状语，主语his wife与leave为逻辑上的主动关系，故填leaving。
(三)作介词的宾语时用动名词
9．(2018·全国卷Ⅰ)You may drink, smoke, be overweight and still reduce your risk of (die) early by running.
解析：dying　reduce one’s risk of ...“降低某人……的风险”，此处介词of后跟动名词形式， 故填dying。
10．(2018·沈阳质量检测)You could easily pay with your smartphone by (scan) the seller’s QR code.
解析：scanning　空处作介词by的宾语，故用动名词形式。
(四)缺少主语常用动词­ing 形式
11．(2018·北京高考改编) (travel) along the old Silk Road is an interesting and rewarding experience.
解析：Traveling/To travel　句意：沿着古老的丝绸之路旅行是一种有趣且有益的体验。分析句子结构可知，空处所在短语在句中作主语，应用动名词或动词不定式形式。
12．(2018·辽宁铁岭协作体一联)Above all, I have come to understand that (bring) happiness to others is getting ourselves happiness.
解析：bringing　句意：首先，我开始明白了赠人玫瑰、手留余香的道理。设空处在宾语从句中作主语，且表示抽象概念，故用动名词作主语。
(五)非谓语动词作表语修饰物时用v.­ing，修饰人时用v.­ed 形式
13．(2018·河南八市重点高中二次质检)I felt hopeless and alone, and more (depress) than I knew was possible.

技法二

技法三
辨清逻辑关系，选用恰当的非谓语动词

解答非谓语动词题的关键是弄清楚非谓语动词与主句主语之间是主谓关系还是动宾关系，主谓关系考虑v.­ing形式，动宾关系考虑v.­ed形式。
1．(2018·北京高考改编)Ordinary soap, (use) correctly, can deal with bacteria effectively.
解析：used　句意：普通的肥皂，如果使用得当，能有效地处理细菌。分析句子结构可知，此处是条件状语从句if it is used correctly的省略，省略了if it is，Ordinary soap与use之间为逻辑上的动宾关系，故填used。
2．(2018·天津高考改编)I need a new passport so I will have to have my photographs (take)．
解析：taken　句意：我需要一个新护照，因此我得去让人给我照相。本句的宾语my photographs与take之间是动宾关系，故用过去分词作宾语补足语。

解析：being noticed　句意：机会常常是悄无声息地来，又默默而去。介词(without)后需用动名词作宾语；主语opportunities与notice之间为逻辑上的动宾关系，故用being noticed。
4．(2018·太原阶段测评)Many of us ignore the problem as the day goes on, (forget) that it might have a dangerous effect.
解析：forgetting　forget与其逻辑主语Many of us之间构成主谓关系，因此用现在分词作状语。
5．(2018·河北五个一名校联盟第二次模拟)One great site is Science News for Kids.This site reports science news (cover) a wide range of subjects.
解析：covering　提示词cover和其所修饰的名词news之间为逻辑上的主谓关系，所以用cover的v.­ing形式作后置定语，在此相当于which covers。
6．(2019·江西五校第一次联考)Antibiotic drugs can lose their effectiveness when people take more or less than the amount (require) by doctors.
解析：required　分析句子结构可知，require和amount之间为逻辑上的动宾关系，故用过去分词作后置定语。
7．(2018·福州市八县市一中联考)At the age of four, she fell into an icy river and was fortunately rescued by some local villagers (live) in Baoxing County in southwest China’s Sichuan Province.
解析：living　名词villagers和动词live之间是逻辑上的主谓关系，故用现在分词作后置定语。
8．(2018·重庆第一次调研)Visitors also may take a walk in the rain forest (create) by the volcano thousands of years ago.
解析：created　分析句子结构可知，forest后面的部分作定语修饰rain forest，且rain forest与动词create之间在逻辑上是动宾关系，故用过去分词作定语。


1．非谓语动词填空的两个原则
(1)主被动原则
逻辑主语与非谓语动词是主谓关系时，用现在分词­ing形式；是动宾关系时用过去分词­ed形式。

(2)时间先后原则
非谓语动词表示正在进行，用现在分词­ing形式；表示已经完成，用过去分词­ed形式；表示将来发生的动作，用不定式to do形式。

(3)有些动词或动词短语既可接不定式作宾语，也可接动名词作宾语，但表示的含义不同。

can’t help

1．现在分词和过去分词作状语

4．不定式与动名词作宾语
有些动词后只跟不定式作宾语，例如agree, decide, refuse, manage等；而有些动词只跟动名词作宾语，例如avoid, finish, mind, practise等。还有些动词既可以跟动名词作宾语，也可以跟不定式作宾语，但意义上有区别，这些都要特别注意。
