非谓语动词-解题步骤

非谓语的解题步骤或思路（1）先判断空格部分所需的是主句，从句还是非谓语动词。

独立的句子，从句或非谓语独立的句子加句号，分号或破折号的话，后再加一个独立的句子。

独立的句子，（逗号）有and,but, so 等词加独立的句子。

（2）再根据主句的主语，来判断主动或被动；（3）接下来再判断时态，（4）如果是否定的话，not一定要放在非谓语的前面（5）一定不要忘记主语一致的原则，如果不一致的话，要把非谓语的独立主语加上。

非谓语常见的位置，或在句子中所担当的成分（1）非谓语动词短语，+ 主句或者是主句，非谓语动词短语这时的非谓语动词短语起到状语的作用例如：influenced by the growing interest in nature, more people enjoy outdaoor activities.在这种情况下，首先,找出主句的主语，然后以主句的主语为出发点，来判断非谓语动词是主动还是被动，如果已有的非谓语动词的主语和主句主语不一致，还要考虑独立主格结构，也就是把非谓语动词的自己的主语加上去：例如：All flights having been cancelled , they decided to takethe train.其次,把非谓语动词和主句的动词比较，看是否同时发生还是有明显的先后。

（2）跟在介词，动词或某些形容词的后面固定搭配只接动词-ing形式而不接不定式作宾语的动词有：admit 承认appreciate 感激avoid 避免put off推迟keep 保持consider 考虑delay/ postpone耽搁dislike 嫌恶resist 抵制mention 提及enjoy 喜欢escape 避免excuse 原谅practice 练习mind介意fancy想不到feel like 意欲finish 完成risk 冒险include 包括forgive 原谅give up 放弃suggest 建议miss 逃过imagine 想象can’t help 情不自禁involve 需要can’t stand 无法忍受understand 理解常见的带介词to的短语：be used to 习惯be related to 与……有关get down to 着手做contribute to 贡献put one’s mind to全神贯注于give rise to 引起be equal to 胜任devote oneself to 献身于lead to 导致be opposed to 反对look forward to 盼望object to 反对stick to 坚持pay attention to 注意（3）介词后一定要加动词的-ing 形式；（4）跟在名词后面做定语时，一般不用having done/ having been done 结构（5）放在句首做主语，一般用动词的ing 和to do …特殊的非谓语短语Generally speaking 一般来说Considering …. 考虑到，鉴于Time/weather permitting 时间、天气允许的话Taking …into account 考虑到Taking …into consideration 考虑到Provided …假如Providing…假如Suppose…假如Supposing…假如Juding from/ by…根据…判断Given sth 假如，如果；鉴于，考虑到Given that…假如，如果；鉴于，考虑到。

非谓语动词解题三步走作者：王正勋来源：《高中生·高考指导》2015年第10期第一步：确定是谓语动词还是非谓语动词。

一般来讲，一个句子只有一个谓语动词。

如果是两个谓语动词并列，要有连词连接；如果没有连词，其中一个要用非谓语动词。

如果是三个或三个以上谓语动词并列时，前面几个谓语动词要用逗号分开，最后两个常用and等连词连接，此时的谓语动词所表示的动作常先后接连发生。

否则要根据具体情况，分析动词之间的关系，确定非谓语动词的形式。

如果and等连词不是放在最后两个动词之间，要分析各个动词的关系，确定哪些是用作谓语动词，哪些是用作非谓语动词，再分析动词之间的关系，确定非谓语动词的形式。

例1 A woman saw him crying and telling him to wait outside a shop.解析：答案为将telling改为told。

分析句子结构可知，tell与saw是并列关系，and前后的谓语动词时态要一致，因此将telling改为told。

例2 The old woman carefully sorted out the eggs，_____（put）them in the basket and headed for the market.解析：答案为putting。

分析句子结构可知，put动作应该与sort out动作同时发生，虽然三个动词中最后两个用and连接，但三个动词并不是接连发生，因此put不能用作谓语动词，而用现在分词充当伴随状语。

第二步：根据非谓语动词发生时间和谓语动词的时间关系确定非谓语动词的时态，根据非谓语动词与其逻辑主语的关系确定非谓语动词的语态。

1. 若所表示的动作与主要谓语的动作同时或几乎同时发生，或是在它之后发生，则用to do（主动）或to be done（被动）。

2. 若与主要谓语的动作（几乎）同时进行，并强调正在进行的情景或持续性，则用to be doing或doing（主动），being done（被动）。

高考英语非谓语动词及其解题技巧及练习题(含答案)一、单项选择非谓语动词1．Today there are more airplanes____ more people than ever before in the skies.A．carry B．carryingC．carried D．to be carrying【答案】B【解析】试题分析：考查现在分词作定语。

句意：现在比以前有有更多的飞机运送乘客。

此处airplane和carrying之间是主动关系，故用现在分词作定语。

故选B。

考点：考查现在分词作定语【名师点睛】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airplanes与动词carry构成逻辑上的主动关系，因此用v.-ing形式作定语。

2．I had been betrayed by those who I trusted several times, ______ in a suspicious attitude towards everything and everyone.A．resulted B．having resulted C．resulting D．to result【答案】C【解析】【详解】考查非谓语做结果状语。

句意：我曾被我信任的人背叛过几次，导致我对每件事和每一个人都抱着怀疑的态度。

“result in...”为固定搭配，意为“导致”。

前一句“我曾被我信任的人背叛过几次”，导致后面的结果“我对每件事和每一个人都抱着怀疑的态度”。

高中英语非谓语动词考查重点和解题方法归纳非谓语动词属于英语语法的三座大山之一，无论在考试中还是平时的英语阅读中所起的作用都举足轻重。

但是，对于这么重要的语法内容，很多同学们却怎么学都学不透，要么完全不懂、做题时全靠“感觉”；要么一知半解，能跳过则跳过。

其实，只要方法正确，遇到有关非谓语动词的题目时就会迎刃而解，更令人开心的是，在平时的英语阅读中再也不需要绕道而行了！一、非谓语动词的含义非谓语动词首先是一种动词形式，其次是这种动词形式不能做谓语，综合这两点，我们将其叫做非谓语动词。

二、非谓语动词的形式非谓语动词包含四种形式，即不定式、动名词、现在分词和过去分词。

其中，每种形式按照发生时间和主被动又包括不同的子形式。

具体如下：1、不定式①基本形式：to do（表示主动，并且一般表示将来）②被动式：to be done（表示被动，并且一般表示将来）③进行式：to be doing （表示主动和进行）④完成时：to have done（表示主动和完成）⑤完成被动式：to have been done（表示被动和完成）⑥完成进行式：to have been doing （表示主动和完成进行）例如：The teacher told us to do morning exercises .老师让我们做早操。

The car to be bought is for his sister.要买的这辆车是给他的姐姐的。

She pretended to be reading when the teacher came into the classroom.老师进来时，她假装正在读书。

The thief is said to have escaped.据说小偷已经逃跑了。

The thief is said to have been arrested.据说小偷已经被抓住了。

She is said to have been working in the factory over the last 20 years.据说在过去的20年里，她一直在这家工厂工作。

非谓语动词一、非谓语动词的概念非谓语形式有三种： 1.动词不定式：to do表示目的和将来2、动词的ing(动名词) : doing表示主动和进行 3.动词的过去分词：done表示被动和完成二、非谓语动词的时态和语态一般式完成式进行式不定式主动to do to have done to be doing被动to be done to have been doneing 形式主动doing having done被动being done having been done过去分词被动done三、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。

一、非谓语动词作主语和表语的比较1、不定式和动名词作主语和表语：1）. 不定式表示一次性的、具体的动词。

动词ing 常表示一般的、泛指的或习惯性的动作。

如：________ is a good form of exercise for both young and old.A. The walkB. WalkingC. To walkD. Walk2）. 不定式作主语时，常用it 作形式主语，即用句型：It is + adj. / n. + (for / of sb. ) to do sth.It’s important for us to learn English well. It’s kind of you to help us.注意：下面几个句型是用动名词：It’s no good / use doing sth. There is no point（in）doing sth2、不定式、动名词、分词作表语的比较：1）、不定式、动名词作表语，.表示主语的内容。

非谓语动词练习一．非谓语题的解题总方法与思路：1. 辨别―谓与非谓‖1.）先看四个答案：如果四个答案分别为动词原形、不定式、现在分词、过去分词等情况，那么这个题多半是非谓语动词题。

2.）看符号：中间有个逗号，末尾有个句号（有时中间没有逗号）；3.）看有没有连接词（引导词）。

如果用逗号隔开的两个部分都没有连接词的话，一部分是句子时，那么另一部分就一定是非句子，而非句子里的动词就是非谓语动词。

2. 找逻辑主语3. 定语态：如果本句的主语（或动词自带的逻辑主语）与它是逻辑上的主谓关系，那么答案一般用Ving形式；如果本句的主语（或动词自带的逻辑主语）与它是逻辑上的动宾关系（被动关系），那么答案一般用V ed形式。

4. 定时态：如果非谓语的动作比谓语先（或先很久）发生，那么非谓语动词要用完成式（to havedone/to have been done/ having done/ Having been done），否则我们要用非谓语的一般式（to do / to be done / doing / being done / done）。

二．非谓语动词可能出现的考查点及易错点：1）在“句子, and/or/but +句子”的并列句结构中，可能会考查“以动词原形开头”的祈使句，四个答案表面上象非谓语，其实考查的是谓语。

1.______hard and you will succeed in the exam.2.______hard or you will fail in the exam.3.______hard , you will succeed in the exam.A. StudyB. T o studyC. S tudyingD. Studied2）在“句子，非句子”结构中，非句子部分用非谓语：4. The teacher devoted his life to his career, ______ most of his students successful in study.A. makeB. to makeC. makingD. made3）在“非句子，句子”结构中，非句子部分用非谓语：5. _________with children, I know what is needed most.A. WorkingB. Having workedC. WorkedD. T o work4) 在“with + 宾语+ 宾语补足语”结构中，宾语补足语可能用非谓语动词：6. With her baby _______ on her back, the woman was cleaning the rich man’s house.A. sleepB. sleptC. to sleepD. sleeping7. With his hair _______ like a role in the film, the boy felt very cool.A. cutB. to be cutC. cuttingD. to cut5）在drive/leave/keep/make/have/let/get/find/hear…等使让动词或感观动词后面作宾语补足语时，也可能用非谓语动词。

GUAN ＧＤONG JIAO YU GAO ZHONG广东教育·高中2020年第12期非谓语动词是高中语法的重点和难点，是阅读理解和书面表达的必备基础，也是语法填空的必考点，每年每套题中有1-3小题。

面对非谓语动词，考生经常感到棘手，得分率不高。

其实，从近3年的高考真题来看，高考对非谓语动词的考查非常简单，仅限于考查to do,doing,done 的基本形式。

也就是说，考生只要掌握非谓语动词的三种最基本的形式，题目便迎刃而解。

为帮助考生突破非谓语动词，我们可以用“三步曲”解决非谓语动词。

第一步，分析句子结构，辨别谓语与非谓语。

根据句子的结构，英语句子可分为简单句、并列句和复合句。

简单句只含有一个主谓结构。

并列句是由并列连词and,or,but,so 等连接的两个或两个以上分句而构成的句子，即S1+并列连词+S2。

复合句是由“主句+引导词+从句(定语从句，状语从句，名词性从句)”构成的句子。

根据以上句子成分分析可知，如果一个句子已经有谓语动词，而且空格前没有并列连词或从属连词，一般为非谓语动词。

如：1.(2020全国Ⅰ卷)Chinese researchers hope to use the in 鄄struments on board Chang ’e-4________(find)and study areas of the South Pole-Aitken basin.2.(2020全国Ⅱ卷)They represent the earth __________(come)back to life and best wishes for new beginnings.3.(2020全国Ⅱ卷)They make great gifs and you see them many times ________(decorate)with red envelopes and mes 鄄sages of good fortune.4.(2020山东卷)The 80,000objects collected by Sir Hans Sloane,for example,________(form)the core collection of the British Museum which opened in 1759.分析：第1～3题谓语动词分别是hope,represent,see ，空格前均无连词，因此，括号中所给词均为非谓语动词。
