2015年高考英语真题分类汇编：专题07 非谓语动词
专题七非谓语动词
1.【2015·湖南】30.When the clerk saw a kind face wrinkled in an apologetic smile, she stood rooted to the ground, ________ whether to stay or leave.
A. wondering
B. wonder
C．to wonder D．wondered
【答案】A
【解析】考查非谓语动词。主句的主语she与动词wonder构成逻辑上的主动关系，因此用v.-ing形式作伴随状语，故选A。句意：当那个小职员看到一张善良的面孔泛起皱纹并歉意地一笑时，她像生了根一样站在那儿，不知道是走还是留。
【考点定位】考查非谓语动词
【名师点睛】
非谓语形式有三种：1、动词不定式：to do 2、动词的ing : doing 3、动词的过去分词：done;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。非谓语动词的做题步骤1、判定是否用非谓语形式。方法：看看句子中是否已有了谓语动词了;2、找非谓语动词的逻辑主语。方法：非谓语动词的逻辑主语一般是句子的主语。3、判断主被动关系。方法：非谓语动词与其逻辑主语的主动还是被动关系。4、判断时间关系。方法：分析句子，看看非谓语动词所表示的动作发生在谓语动作之前、之后还是同时。之前常用done; 之后常用to do; 同时常用doing.从本题来看主句的主语she与动词wonder 构成逻辑上的主动关系，因此用v.-ing形式作伴随状语。

的是分词做伴随状语，分为现在分词和过去分词，现在分词短语表示与主句的主语在逻辑上
有主谓关系，即表示主动意义；而过去分词短语则表示与主句的主语在逻辑上是动宾关系，
即被动意义；He sen me an e-mail hoping to ge further information 他给我发一封电子邮件，希
望得到更多的信息；He hurried to the hall, followed by two guards. 他匆忙进了大厅，后面跟

C. to perform
D. being performed 【答案】D
【解析】
试题分析：句意：在家里面听音乐是一回事，去到现场听又是另一回事。hear sb/sth doing 表
听到某人某物做某事。由于音乐是被演奏的，所以需要被动，所以选D。分析4个选项知道，
答案所使用的是同一个动词，不同的是时态、语态或者是非谓语形式。A是动词原形，B
是非谓语现在分词形式，C是非谓语的不定式，D是非谓语的现在分词被动形式。分析句子
结构以及用法，不难知道音乐是被演奏的，所以需要被动，所以选D。
【考点定位】考查动词非谓语
【名师点睛】解答此题，既需要正确区分非谓语和谓语的用法，又要对语态中的被动和主动有所了解，另外也要对hear 这个感官动词的用法有了解。其中的非谓语和谓语可以根据句子成分划分得出，而语态关键看主语是人还是物。当物作主语时需要用被动。
8.【2015·天津】8. ______ for two days, Steve managed to finish his report on schedule.
A. To work
B. Worked
C. To be working
D. Having worked
【答案】D
【解析】

【名师点睛】本题考查的非谓语动词为高中重点语法之一。在分析题目的时候，首先要抓住非谓语动词所对应的逻辑主语，再分析二者之间的关系，现在分词完成式表示其动作发生在句子谓语动作之前，放在句首的不定式只能表示目的性，故应当排除。

D. spending 【答案】C
【解析】
试题分析：句意：上班族们坐在办工座前太久，一般会受到健康问题的困扰。分析句子结构可知，分词的逻辑主语和后面主句的主语不一致，应用独立主格结构。分词主语和分词动作之间构成逻辑上的动宾关系，且动作已完成，故用过去分词。故选C项。
【考点定位】独立主格结构
【名师点睛】考生要抓住非谓语动词考点做题重要原则：非谓语动词作状语，其逻辑主语必须和句子主语保持一致，和句子主语构成主谓关系时用-ing形式，构成动宾关系是用-ed形式。其逻辑主语和句子主语不一致时，要在非谓语动词前加逻辑主语，构成独立主格结构。

For her drive and creativity in overcoming those challenges,she’s been named national teacher of the year. Principal Waynes Kettler said he’s worked with many outstanding teachers in his22years as an educator,but Peterson is“just that one step above anybody I’ve ever worked with before.” Kettler and others at Monte Cristo Elementary School talk about the ways she has introduced the learning from other classrooms into her music program and her creativity in working around things such as the lack of money for new music. When students were reading S.E.Hinton’s novel The Outsiders in their regular classroom, Peterson helped them write a30-minute play with scenes from the book.Then they chose three Broadway tunes that focused no race,equality and social justice,the themes of the book.Peterson composed two other songs herself after classroom discussions about the play and the book. The honor means a lot to residents of Granite Foils.It’s inspiring to know that people from small towns own even win national honors. As national teacher of the year,Peterson will spend the next year outside the classroom, as a national and international spokeswoman for education. Not surprisingly,She is a big believe in the value of arts education.She said it’s essential for schools to offer classes such as art or music and physical education because for some kids one of those subjects is the only thing that motivates them to come back to school day after day. 65.The underlined word“daunting”in Paragraph1most probably means__________.
