新概念第三册语法总结《新概念英语》第三册是一本以阅读为主的英语教材，通过阅读文章来帮助学生提高阅读理解能力和语言表达能力。

在文章中，语法也是非常重要的一部分。

下面是《新概念英语》第三册中涉及的一些语法总结。

一、冠词的用法：1. 不定冠词a/an的用法：表示泛指、数量不明确的单数可数名词前。

例：I have a car. (表示所拥有的一辆车，但没有说明具体是哪一辆)2. 定冠词the的用法：表示特指或已提到过的名词前。

例：Can you pass me the book on the table? (特指桌子上的那本书)二、名词的数的变化：1. 一般情况下，单数变复数在词尾加-s，如：book-books。

2. 以辅音字母+y结尾的单数名词，将y变为i再加-es，如：city-cities。

3. 以-f或-fe结尾的名词，变-f或-fe为-v并加-es，如：wife-wives。

三、动词的时态：1. 一般现在时：表示习惯性、经常性或客观真理等。

例：Water boils at 100 degrees Celsius. (客观真理)2. 一般过去时：表示过去发生或存在的动作或状态。

例：She lived in London for five years. (过去发生的动作)3. 现在进行时：表示现在正在进行的动作。

例：I am reading a book now. (正在进行的动作)4. 过去进行时：表示过去某一时间正在进行的动作。

例：He was studying when I called him. (过去某一时间正在进行的动作)5. 一般将来时：表示将来某一时间将要发生的动作。

例：I will go to the cinema tomorrow. (将来某一时间将要发生的动作)四、形容词和副词的比较等级：1. 一般形容词比较等级：例：good - better - best (好 - 更好 - 最好)2. 以-y结尾的形容词，变-y为-i，再加-er或-est：例：happy - happier - happiest (快乐 - 更快乐 - 最快乐)五、连词的用法：1. 并列连词and：用于连接并列的词、短语、从句等。

王牌要点：通常由that或疑问词导出。

1. How some mammals came to live in the sea is not know.〔主语从句〕2. The attorney told his client that they had little chance of winning the case.〔宾语从句〕3. The problem is what we'll do next.〔表语从句〕4. We have no idea that he has come back.〔同位语从句〕同位语〔Appositive〕:同位语是英语语法的重点内容，也是各类考试中的一个考点，同时，在写作中正确运用同位语可以使你的句型更加简洁得体。

新概念英语? 第三册第一课有这样一个句子：When reports came into London zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.45英里在这里，a wild puma had been spotted forty-five miles south of London就是同位语从句，它本来应该放在“reports〞后面，这里却被放在了谓语成分came into London zoo的后面，目的是让句型显得更为稳重。

I．简单记忆：同位语从句，就是对某些名词做进一步的解释的句子。

I was greatly shocked when I heard the news that his father died yesterday.〔that 引导的句子解释了news的内容，注意：that不做任何成分〕We have to face the fact that the weather is unexpectedly bad.〔that 引导的句子解释了fact的内容〕II．联想记忆：［大声朗读三遍，背下即可。

新概念三的语法知识点总结一、动词时态动词时态是表示动作发生的时间的一种语法形式。

在新概念三中，涉及了一些基本的动词时态，包括一般现在时、一般过去时、一般将来时等。

学习者需要掌握这些时态的构成和用法，才能正确地表达自己的意思。

在此，我们将分别总结各个时态的构成和用法。

1. 一般现在时动词的一般现在时表示经常性、习惯性或普遍性的动作或状态。

它的构成为“主语+动词原形（第三人称单数要加-s）+其他”。

例如，“I always go to work by bike.”（我总是骑自行车上班）。

2. 一般过去时动词的一般过去时表示在过去某个具体时间或某个时间段内发生的动作或存在的状态。

它的构成为“主语+动词过去式+其他”。

例如，“I lived in Beijing for ten years.”（我在北京住了十年）。

3. 一般将来时动词的一般将来时表示将来某个时间会发生的动作或存在的状态。

它的构成为“主语+will/shall+动词原形+其他”。

例如，“He will come to see me tomorrow.”（他明天会来看我）。

二、语态语态是表示动作与主语的关系的一种语法形式，包括主动语态和被动语态。

在新概念三中，也涉及了被动语态的用法。

被动语态的构成为“be+动词的过去分词+其他”。

例如，“The letter was written by Tom.”（这封信是汤姆写的）。

三、条件句条件句是表示假设、条件的一种语法形式，主要包括真实条件句和虚拟条件句。

在新概念三中，学习者需要掌握这两种条件句的构成和用法，以便正确地运用它们来表达自己的意思。

1. 真实条件句真实条件句表示与事实相符的假设条件，用于表达可能性或必然性。

它的构成为“if/whether+现在时/过去时，主句用一般现在时/一般过去时”。

例如，“If it rains tomorrow, I will stay at home.”（如果明天下雨，我就呆在家）。
