英语语法归纳之非谓语动词(过去分词)
英语语法归纳之非谓语动词（动名词） 敬告： 以下内容，不参加高考等有语法题（语法单选、语法填空、短文改错等）考试的应用类学员无须深究，知道该语法结构的存在，及其充当的句子成分和功能即可，应多花时间练习听说读写，否则就背离了语言学习真正目的。应试类学员有时间可以比较分析，基本搞懂。 过去分词长什么样？规则的情况下与动词过去式相同，当然有不规则的情况；过去分词可以充当定语、状语、补语、定语，不可能充当主语、宾语； 过去分词不像现在分词有多种体现时态和语态的形式，只有一种形式done表示。 1、过去分词可以充当主谓宾补句型中的宾语补语；它与宾语是被动关系，或者说它与宾语是动宾关系。 (1) We found the fish eaten by our cat. (2) I can’t make myself understood because of my poor English. 2、过去分词可以充当定语；充当定语当然是修饰主语、宾语等名性的结构；表达过去分词的动作是被动的或完成，或即被动又完成的。 (1) The party had last night (which was had last night) was very cheerful. (2) USA is a developed country (a country which has been developed). (3) A great number of students questioned (who had been questioned) said they were forced to practice the piano. 3、过分词可以充当状语，它与主句主语是被动关系，或者说它与主句的主语是动宾关系； 过去分词一般只强调被动动作而不强调时间，多用于条件和原因状语；(1) Taken in time, the medicine will turn out to be very effective. If the medicine is taken in time, it will turn out to be very effective. (2) Offered an important role in a new movie, Andy has a chance to become famous.
主谓一致用法详解及练习题 附答案
．主谓一致 主谓一致是指一个句子的主语和谓语动词保持数的一致关系。英语主谓一致一般要遵循三条原则，即：语法一致原则；意义一致原则和就近原则。 1.语法一致原则 语法一致原则是指谓语动词和它的主语在语法形式上必须取得一致，即主语是单数形式，谓语动词用单数形式，主语为复数形式，谓语动词也用复数形式，如： Tom doesn’t like swimming. 汤姆不喜欢游泳。 Jane and Mary look alike. 简和玛丽看起来很像。 2.意义一致原则 意义一致原则是指谓语动词和主语的一致，同由主语所表达的单数概念来决定，而不是根据主语的实际语法形式。 有时主语的语法形式是单数，但所表达的概念是复数意义，这时动词应采用复数形式，如： The football team are having breakfast now. 足球队员们在吃早饭。 The news was exciting. 这条消息令人振奋。 3.就近原则 就近原则指谓语动词的人称和数要在形式上与最靠近它的那个名词或代词取得一致。当一个句子有两个主语而它们又是either...or…, neither…nor…, not only…but also…, or 等连接时，谓语动词与靠近它的主语保持一致，如： Either your students or Mr Wang knows this. 你的学生们或王老师知道这件事。 Neither Jim nor his friends were interested in this film. 汤姆和他的朋友们都对这部电影不感兴趣。 主谓一致这三个原则中有很多需要注意的问题， 1.主语为集体名词 (1)某些集体名词既可表示单数也可表示复数。如果集体名词作为一个整体看待，谓语动词用单数形式，如果就其中一 个成员而言，谓语动词用复数形式，如： Our group were discussing heatedly on the subject. 我们小组成员正对这个问题进行热烈的讨论。（group 指小组成员）Our group is made up of four girls and five boys. 我们小组有4个女孩和5个男孩组成。（group 指小组整体） The population in China is very large, and one third of the population are farmers. 中国的人口很多，其中三分之一是农民。（前一个population 指整体，后一个population 指成员） (2)某些集体名词如people, police, cattle, youth 等常作复数看待，谓语动词与复数形式的谓语搭配，如： The police are searching for him. 警察正在搜寻他。 The cattle were driven away from the hill. 那些牲畜从山上被赶走了。 3.某些名词如equipment（设备），furniture（家具），jewelry（珠宝），clothing（衣服），machinery（机械），表示单数 概念，谓语动词要相应地采用单数形式,如： A lot of equipment has been replaced by the new equipment. 许多旧设备已经被新设备代替了。 All the machinery in the factory was controlled by robots. 这个厂所有的机械都由机器人来控制的。 2.主语为代词 (1)．有些代词尽管意义上是多数，但谓语动词要用单数形式，这类代词有：either, neither, each, another, somebody, someone, something, anything, anyone, everyone, everything, everybody, no one, nothing, nobody 等，如： Neither likes the friends of the other. 两人都不喜欢对方的朋友。 Everything around us is matter. 我们周围所有的东西都是物质。 注意： ①在neither of 与either of 的结构中，谓语动词可用单数形式也可用复数形式，如： Neither of them was / were in good health, but both worked hard. 他们俩身体都不好，但工作却都很努力。 ②each 用于单数名词前，谓语动词用单数形式, each 用于复数主语后，谓语动词用复数形式。each of, each one of 后 接复数名词或代词，但谓语动词常用单数形式。 Each (one) of the houses was different. 每座房子都不同。 Each student has been given their own e-mail address. 每个学生都得到了一个自己的电子邮件地址。
江苏高考英语语法专题复习知识点汇总
江苏高考英语语法专题复习知识点汇总 一、冠词The Article 知识要点： 冠词是一种虚词，放在名词的前面，帮助说明名词的含义。冠词分不定冠词（The Indefinite Article）和定冠词（The definite Article）两种。a (an) 是不定冠词，a用在辅音之前：如a book, a man; an用在元音之前，如：an old man, an hour, an interesting book等。the是定冠词。 一、不定冠词的用法 1、指人或事物的某一种类（泛指）。这是不定冠词a (an)的基本用法。如：She is a girl. I am a teacher. Please pass me an apple. 2、指某人或某物，但不具体说明何人或何物。如：He borrowed a story-book from the library. A Li is looking for you. 一位姓李的同志正在找你。 3、表示数量，有“一”的意思，但数的概念没有one强烈。如： I have a mouth, a nose and two eyes. 4、用于某些固定词组中。如： a bit, a few, a little, a lot of, a piece of, a cup of, a glass of, a pile of, a pair of, have a good time, for a while, for a long time等。 5、用在抽象名词前，表具体的介绍——a + 抽象名词，起具体化的作用。如： This little girl is a joy to her parents. 这女孩对她父母来说是一个乐趣。 It is a pleasure to talk with you. 跟您交谈真是一件愉快的事情。 It is an honour to me to attend the meeting. 参加这个会，对我来说是一种荣誉。 二、定冠词的用法： 1、特指某（些）人或某（些）事物。这是定冠词the的基本用法。如： Beijing is the capital of China. The pen on the desk is mine. 2、指谈话双方都知道的人或事物。如： Where is the teacher? Open the window, please. 3、指上文提过的人或事物（第二次出现）。如： There was a chair by the window. On the chair sat a young woman with a baby in her arms. The baby was thin. 4、用在世界上独一无二的事物前。如：

高考英语常考必考六个语法知识点
高考英语常考必考六个语法知识点 高考英语常考必考六个语法知识点 1. 语态和时态 —do you see those people on the little sandy island? —yes, they _______ handkerchiefs for the last half hour. i wonder why. a. were waving b. waved c. had waved d. have been waving 【正确答案】d 【高考考点】考查动词时态。现在完成进行时：表示一个从过去某一时刻开始的动作，一直延续到说话时还在进行或刚结束，句中常出现用for, since,how long等引导的时间状语。 his telephone has been ringing for a long it hasbeen raining since last sunday. how long have you been wearing glasses? 【题干句意】“你有没有看见那些在小岛上的人?”“是的，我看见了。他们在过去的半小时里一直在挥手帕，我不知道为什么。” 【详细解析】这个挥手帕的动作是在半小时前开始的，然后一直在挥，一直挥到了说话的这个时候，所以我们用的是一个现在完成进行时，强调一个动作的持续。我们再来看
一下其他几个时态： a选项是were waving——过去进行时，它指的是：①过去某一时刻正在进行;②过去某一阶段正在进行;——过去时，过去某时间发生的且已完成的动作，所以我们知道a 和b这两个时态都是和过去有关，而和现在是没有一点关系的，所以a和b这两个答案错了。 c. had waved——过去完成时：过去某一时刻或某一动作前完成的动作或状态，那么它所表达的时候是在过去的过去，例如： by theend of last year, we had built 5 newschools.到去年年底为止，我们已经建造了5所学校。首先，过去的时间是去年年底;而句子表达的意思是在去年年底之前，所以我们用过去完成时——hadbuil d.和现在是更加没有联系了，所以这个答案也是不正确的。 题干中的时间状语是“for the last halfhour”，注意这个last不是指“最后的”，而是指“刚才的——在刚才的半个小时里”，那么往往呢句中出现last,或者是last halfhour、recent这种词的话，我们一般都会选择现在完成进行时，因为它指的是“刚才”，那么肯定指“从刚才到现在”。所以本题答案是d. 2. 名词性从句 the information could be helpful to ____will take over the job.
非谓语动词用法详解
非谓语动词用法详解 动词的非谓语形式有三种：不定式、动名词和分词 (一)不定式 不定式由“to十动词原形”构成，其否定形式是“not to do”．不定式可以带宾语或状语构成不定式短语，没有人称和数的变化，但有时态和语态的变化．不定式可作主语、宾语、状语、表语和定语，但不能单独作谓语．不定式的逻辑主语有时用“for十名词或代词宾格”构成． 1．不定式的用法： l)作主语．不定式短语作主语时，往往放在谓语之后，用it作形式主语．例如： To see is to believe． It is right to give up smoking． 2)作宾语．不定式短语作宾语时，如果还带有宾语补足语。往往把不定式宾语放在宾语补足语之后，而用it作形式宾语．例如： He wanted to go． I find it interesting to study work with him. 3)作宾语补足语．例如： He asked me to do the work with him. 注意：在feel，hear，listen to，look at，notice, observe，see，watch，have, let，make等词后的补足语中，不定式不带to．但是这些句子如果变成被动结构时，就必须带to．例如 I often hear him sing the song． He is often heard to sing the song． 注意：不定式动词在介词but，except，besides后面时，如果这些介词之前有行为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to．如： She could do nothing but cry. What do you like to do besides swim? I have no choice but to go． 动词help之后，带to或不带to都可以。 Will you please help me (to) take this suitcase? 请你帮我提一下这个衣箱好吗？She often helps her mother (to) clean their house. 她经常帮助她妈妈打扫房子。 4)作定语．例如： I have some books for you to read． 注①作定语的不定式如果是不及物动词，或者不定式所修饰的名词或代词是不定式动作的地点、工具等，不定式后面须有相应的介词．例如： He is looking for a room to live in． There is nothing to worry about．
