时态和语态语法讲解和练习

时态专题讲解构成时态的助动词be (is, am, are), have (has), shall, will 等需根据主语的变化来选择。

时态是英语中一个重要的语法范畴，它表示不同时间发生的动作或存在的状态以及动作发生或存在的方式。

动作发生的时间可分为现在、过去、将来和过去将来四种形式，动作发生的方式可分为一般、完成、进行和完成进行四种形式。

将时间形式和动作方式结合起来，就构成了以下一般完成进行完成进行现在一般现在时do 现在完成时have done现在进行时is doing现在完成进行时have been doing过去一般过去时did 过去完成时had done过去进行时was doing过去完成进行时had been doing将来一般将来时will do 将来完成时will have done将来进行时will be doing将来完成进行时will have been doing过去将来过去将来一般时would do过去将来完成时would have done过去将来进行时would be doing过去将来完成进行时would have beendoing英语的时态是靠动词的变化和时间状语来表达的。

英语中的时态共有十六种，但是常考的或较常用的只有9种。

要掌握英语的时态和语态，必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。

一般现在时用法：A) 经常性、习惯性动作。

例：He always helps others. （他总是帮助别人。

）B) 客观事实和普遍真理。

尤其要注意，如果前后文不是一般现在时，则无法保持主句、从句时态一致He said lights goes faster than sound. 他说光比声音传播的快。

C) 表示一个按规定、计划或安排要发生的动作，（仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词）可以与表示未来时间的状语搭配使用。

语法：时态语态综合初中阶段考查8种时态，分别是一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时和过去将来时。

今天我们涉及6个时态，分别是一般现在时、一般过去时、一般将来时、现在进行时、过去进行时和现在完成时。

英语的语态分为主动语态和被动语态，主动语态表示主语是动作的执行者。

被动语态表示主语是动作的承受者，目前中考主要考查一般现在时、一般过去时、一般将来时和现在完成时这四种时态的被动语态以及含情态动词的被动语态。

只有及物动词才有被动语态。

它的基本结构为：be动词+及物动词的过去分词。

所有的时态变化在be动词上。

动词时态：动词语态注意以下几种被动语态的特殊情况：一．被动语态中不定式要还原Let/make/see/hear/watch sb. do sth.----- sb. be let/made/seen/heard/watched to do sth.My mother made me look after the little sister yesterday.----I was made to look after the little sister by my mother yesterday.二．有些动词没有被动语态。

(及物动词才有被动语态)1) 不及物动词或动词短语无被动语态：appear, die，disappear, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, stand break out, come true, fall asleep, keep silence, lose heart, take place.2) 系动词无被动语态：appear, be，become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn3) 不能用于被动语态的及物动词或动词短语：fit, have, hold, marry, own, wish, cost, notice, watch，agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to4) 系动词无被动语态：appear, be，become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn5) 当宾语是不定式时，很少用于被动语态。

语法练习语态时态和语气语法练习：语态、时态和语气语法中的语态、时态和语气是我们编写准确、流畅的句子所必须掌握的重要要素。

正确运用这些语法规则，可以使我们的表达更加清晰、准确。

本文将对语态、时态和语气进行分析和练习。

一、语态（Voice）语态是表示动作的主语与谓语动词之间的关系，典型的语态有主动态和被动态。

1. 主动态（Active Voice）：强调主语执行动作。

例句：Tom eats an apple.（汤姆吃了一个苹果。

）2. 被动态（Passive Voice）：强调动作的承受者。

例句：The apple is eaten by Tom.（苹果被汤姆吃了。

）练习：将下列主动态句子改写为被动态。

1. She opened the window.2. They built a new house.3. He will finish the work tomorrow.答案：1. The window was opened by her.2. A new house was built by them.3. The work will be finished by him tomorrow.二、时态（Tense）时态是表示动作发生的时间，常见的时态有一般现在时、一般过去时、一般将来时等。

1. 一般现在时（Simple Present）：表示经常性或普遍性的动作或状态。

例句：She works in a hospital.（她在医院工作。

）2. 一般过去时（Simple Past）：表示过去发生的动作或状态。

例句：I studied English last night.（昨晚我学英语了。

）3. 一般将来时（Simple Future）：表示将来发生的动作或状态。

例句：We will visit our grandparents next month.（下个月我们将去拜访祖父母。

）练习：将下列句子改写为对应时态。

动词的语态和时态的区别与用法动词是语言中最重要的组成部分之一，它们描述了动作、状态或事件的发生和发展。

在语法中，动词分为不同的语态和时态，这些语态和时态有着不同的用法和含义。

本文将详细介绍动词的语态和时态的区别以及它们的正确用法。

一、动词的语态1. 主动语态主动语态是指主语是动作的执行者，它强调主体的主动性和行动能力。

在主动语态中，动词直接表示动作的发出。

举例：- The boy kicked the ball.（这个男孩踢了球。

）- She wrote a letter.（她写了一封信。

）- He paints a picture.（他正在画一幅画。

）2. 被动语态被动语态是指主语是动作的接受者或承受者，它强调动作对主体的影响或是由外界施加给主体。

在被动语态中，动词通常由 "be" 加以变化，并在后面加上动作的执行者。

举例：- The ball was kicked by the boy.（球被男孩踢了。

）- A letter was written by her.（一封信被她写了。

）- The picture is being painted by him.（这幅画正在被他画。

）被动语态多用于强调动作的接受者或者主体的无法执行动作的情况。

二、动词的时态1. 现在时现在时态用于表示目前正在进行或经常发生的动作、状态或事件。

举例：- I go to school every day.（我每天去学校。

）- She is reading a book now.（她现在在读一本书。

）- They often play football on weekends.（他们经常在周末踢足球。

）2. 过去时过去时态用于表示已经发生或已经结束的动作、状态或事件。

举例：- I went to the park yesterday.（我昨天去了公园。

）- He studied in the library for three hours.（他在图书馆学习了三个小时。

一般将来时讲解与练习一、概念：表示将要发生的动作或存在的状态句中一般有以下时间状语：tonight，in the future，tomorrow, next day(week, month, year…),soon, the day after tomorrow（后天），in+段时间（在...之后）等。

二、基本结构：①主语+be going to + do；②主语+will+ do. ③主语(只能为I /We)+shall+do三、否定句：在①be动词（am, is, are）后加not；②will后加not成won’t；③shall后加not成shan’t例如：I’m going to have a picnic this afternoon. →I’m not going to have a picnic this afternoon.四、一般疑问句：be或will或shall提到句首，some改为any, and改为or，第一二人称互换。

例如：We are going to go for a walk this weekend.→Are you going to go for a walk this weekend?五、对划线部分提问。

一般情况，一般将来时的对划线部分有三种情况。

1. 问人。

Who 例如：I’m going to New York soon. →Who’s going to New York soon.2. 问干什么。

What …do.例如：My father is going to watch a match with me this afternoon.→What is your father going to do with you this afternoon?3. 问什么时候。

When. 例如：She’s going to go to bed at nine. →When is she going to bed?六、同义句：be going to = willI am going to go swimming tomorrow. = I will go swimming tomorrow.七、be going to和will 的区别be going to和will 的用法虽然都表示将来发生动作或情况，但它们的用法是有区别的。

语法解析动词时态和语态动词是语法中一个非常重要的词类，它在句子中负责表达动作、状态、事件的发生或存在。

动词的时态和语态是我们在学习和使用动词时需要重点关注的两个方面。

本文将对动词的时态和语态进行详细的解析和讨论。

一、动词的时态动词的时态指的是动作发生的时间，主要分为一般现在时、一般过去时、一般将来时等几种。

1. 一般现在时（Simple Present Tense）一般现在时表示经常性或习惯性的动作、客观真理、科学事实等。

例如：- He reads books every day.（他每天都读书。

）- Water boils at 100 degrees Celsius.（水在100摄氏度时煮沸。

）2. 一般过去时（Simple Past Tense）一般过去时表示过去某个时间发生的动作或存在的状态。

例如：- They went to the park yesterday.（他们昨天去了公园。

）- Mary studied English when she was in college.（玛丽上大学时学习了英语。

）3. 一般将来时（Simple Future Tense）一般将来时表示将来某个时间将要发生的动作或存在的状态。

例如：- I will travel to Beijing next month.（我下个月将去北京旅行。

）- They are going to have a party tonight.（他们今晚将举办一个派对。

）除了上述的三种基本时态，动词还有一些其他的时态形式，如现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时等。

这些时态形式在表达不同的情况和语境时使用，可以增强句子的准确度和表达力。

二、动词的语态动词的语态指的是动作的主体和所受到的影响，主要分为主动语态和被动语态两种。

1. 主动语态（Active Voice）主动语态表示主体执行动作或发生状态。

初中重点语法：一般现在时第一部分：定义与详解第二部分：练习和语法解析一、定义与讲解一般现在时：表示经常性，习惯性的动作或状态。

时间状语：often 经常，usually通常，always 总是，every每个，sometimes 有时，never从不，seldom 极少结构：动词原形（第三人称单数+s/es）。

第三人称单数变化：(1)直接在动词词尾加-s.ask---asks work---works get---gets stay---stays(2)以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es.watch---watches wish---wishesfix---fixes do---does go---goes pass---passes(3)以“辅音字母加- y”结尾的动词，要先变y为i再加-es.try---tries study---studies cry---cries fly---flies2.不规则变化：be---- is are have----has二、一般现在时用法图片1. 表示经常性，习惯性,永久性的动作或存在的状态。

通常与副词sometimes, often, usually, always, every day (year, month ), once (twice, three times) a day,等时间状语连用。

例：They usually go to school by bike.I take the medicine three times a day.She helps her mother once a week.Mary’s father is a policeman.There are 50 students in my class.2. 表示客观真理，科学原理，自然现象，等客观事实或格言，谚语等。

例：The sun rises in the east and sets in the west every day.Tomorrow is Tuesday.三、一般现在时的句型转换(1)当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.例：①陈述句：She is a student.疑问句→Is she a student?否定句→She is not a student.②陈述句：I can swim.疑问句→Can you swim？否定句→I can not swim.(2) 当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does(单数she,he,it)变成问句;在主语后谓语动词前加助动词don’t(I,you,以及复数), doesn’t(单数she,he,it)变成否定句，助动词后的动词要变成动词原形。
