1．Recently a survey _______ prices of the same goods in two different supermarkets has caused heated debate among citizens.
A．compared B．comparing C．compares D．being compared 【答案】B
【解析】
【详解】
考查非谓语动词。句意：最近，一项对两家不同超市的同种商品价格进行比较的调查在市民中引起了激烈的争论。分析句子结构可知，该句的主语是a survey，谓语动词是has caused，宾语是heated debate。可见，句子结构是完整的，因此我们要选择的只能是非谓语动词形式。survey与compare之间存在主动关系，因此用现在分词短语作后置定语。故选B。
2．Children who are over-protected by their parents may become _____.
A．hurt B．spoiled C．damaged D．harmed
【答案】B
【解析】

5．I’m afraid that I can’t attend Tom’s wedding party ______ next weekend.
A．to be held B．being held
C．held D．is to be held
【答案】A
【解析】
试题分析：考查非谓语动词作定语。句子中已经有了谓语can't attend，故此处应填非谓语动词，首先排除D。hold与party构成被动关系，但ABC答案均表被动。因此再根据时间状语next weekend可确定填不定式表将来，故选A。考查非谓语动词作定语时，要注意看与所修饰名词之间的关系，判断是主动还是被动。同时还要注意从时间上判定，不定式作定语表将来，现在分词表进行，过去分词表完成。

6．After receiving the Oscar for Best Supporting Actress, Anne Benedict went on all the people who had helped in her career.

C．having thanked D．to have thanked
【答案】A
【解析】
试题分析：句意：在获得奥斯卡最佳女配角后，Anne Benedict继续感谢所有帮助她演绎生涯的人。go on to do继续做不同的事情，所以选A。
考点：考查不定式
【名师点睛】不定式有一些具体的用法，可以做宾语，定语，状语。还有不定式的不同形式：to do；to be doing；to have done。这题要注意go on to do“继续做不同的事情”和go on doing“继续做相同的事情”的区别。结合语境是关键。

【解析】
【详解】

8．_____________in the poorest area of Glasgow, he had a long, hard road to becoming a
football star.
A．Being raised B．Raising
C．Raised D．To raise
【答案】C
【解析】
试题分析：句意：他在格拉斯哥最穷的地方长大，要想成为足球明星还有很长的路要走。根据句意可知raise这个动词的主语是he，他在这个地方长大，两者之间是主谓关系，故选C项。
考点：考查非谓语谓语动词。
【名师点睛】本题在考查非谓语动词，题目难度中等，从选项看，不定式：表示目的和将来；动词的ing：表示主动和进行；过去分词：表示被动和完成。从句子结构判断，两个句子是否共用一个主语，主语与第一个动词之间是主谓关系还是动宾关系，再者还要注意判断时间关系，从而得出答案来。

【解析】考查非谓语动词。句意：在这期间，大约创造13,500个新的工作，超过市场分析师持有的12,000个的预期数量。分析全句可知，这里指前一件事情所带来自然而然的结果，故用现在分词作结果状语。故选D。
点睛：本题考查非谓语动词。非谓语动词主要有动词不定式、现在分词和过去分词形式。having exceeded强调时间先后，指的是此动作发生在谓语动词create的动作之前；to exceed表示将要超出；exceeded过去分词表示被动。分析句子可知，这里用现在分词作结果状语。

表被动和完成，故选D项。
【点睛】
本句考查独立主格
独立主格结构是由名词或代词加上分词等构成的一种独立结构，用于修饰整个句子。
其结构为：名词/代词+to do/ doing/done/adj/ adv/ n
以本题为例：
因为前后两部分有独立的主语，且没有连接词，故判断前面部分是独立主格结构，名词a total of 19 Golden Rooster Awards和present之间为被动关系，且这个动作已完成，故用过去分词presented表被动和完成。

A．Attend B．To attend C．Attending D．Having attended 【答案】C 【解析】 主句 .Distinguished guests and friends are our alumni （校友） from home and abroad. Attending the ceremony of the 50th Anniversary this morning非谓语动词作伴随状语。 2．(天津) The hospital has recently obtained new medical equipment, ________ more patients to be treated. A．being allowed B．allowing C．having allowed D．allowed 【答案】B 【解析】 【详解】 考查非谓语动词。句意：近期这个医院购进了新的医疗设备，允许更多的病人被治疗。前句购进医疗设备和后面允许更多的病人被治疗之间是必然的结果关系，用doing即现在分词作结果状语，表示顺理成章的结果。A. being allowed表示被动且正在进行；C. having allowed 强调先于谓语动词发生；D. allowed表示被动且完成，故选B。 【点睛】 判断非谓语动词的形式的第一步是分析句子成分，看是用谓语动词还是非谓语动词，确定了是非谓语动词，还要判断非谓语动词的成分，和这个动词和逻辑主语的关系。 3．While waiting for the opportunity to get , Henry did his best to perform his duty. A．promote B．promoted C．promoting D．to promote 【答案】B 【解析】 试题分析：本题考查的非谓语动词的固定搭配“get+过去分词”，如“get burnt”被烫伤，get paid获得报酬；本句中的get promoted获得提拔。句意：在等待着背提拔的机会的时候，Herry全力以赴地尽好自己的责任。故B正确。 4．When we saw the road ________ with snow, we decided to spend the holiday at home. A．block B．to block C．blocking D．blocked

高考非谓语动词易错题汇总 一、单项选择非谓语动词 1．Mr. Wang made up his mind to devote all he could ____ his oral English before going abroad. A．improve B．to improving C．improving D．to improve 【答案】B 【解析】 【详解】 考查非谓语动词。句意：王先生决心在出国前尽其所能提高英语口语。此处是devote…to…“将……奉献给；把……专用于”，to是介词，he could (devote)是all的定语从句，由此可知，B项正确。故选B。 2．I’m afraid that I can’t attend Tom’s wedding party ______ next weekend. A．to be held B．being held C．held D．is to be held 【答案】A 【解析】 试题分析：考查非谓语动词作定语。句子中已经有了谓语can't attend，故此处应填非谓语动词，首先排除D。hold与party构成被动关系，但ABC答案均表被动。因此再根据时间状语next weekend可确定填不定式表将来，故选A。考查非谓语动词作定语时，要注意看与所修饰名词之间的关系，判断是主动还是被动。同时还要注意从时间上判定，不定式作定语表将来，现在分词表进行，过去分词表完成。 考点：考查非谓语动词作定语。 3．A hearty laugh relieves physical tension, _____your muscles relaxed for over half an hour. A．to leave B．left C．leaving D．leave 【答案】C 【解析】 【详解】 考查非谓语动词。句意：开怀大笑可以缓解身体紧张，至少可以使你的肌肉放松半小时。分析句子可知，空格处做伴随状语。且与逻辑主语laugh构成主动关系，所以用现在分词。故选C。 4． He is thought ___foolishly .Now he has no one but himself to blame for losing the job. A．to act B． to have acted C． acting D．having acted 【答案】B 【解析】 试题分析：句型“有人认为..已....”可用It is thought/ believed/ ...that sb have/has done...结构。从句中的动作发生在主句动作之前。该结构可转化为sb is thought/believed +不定式的完成式。如：
