系动词Be(am, is, are )的用法:
一、口诀:
我用am,你用are,is连着他,她,它;
单数名词用is,复数名词全用are;
变疑问,往前提,句末问号某丢弃;
变否定,更容易,be后莫忘记;
疑问否定任你变,句首大写莫迟疑。

二、Be动词在一般过去时中的变化:
1、am和is在一般过去时中变为was;
2、are在一般过去时中变为were
3、带有was或were的句子,其否定、疑问的变化和am is are一样,即否定句在was或were后加 not,一般疑问句把was或were调到句首。

考点名称:助动词

  • 助动词:
    协助主要动词构成谓语动词词组的词叫助动词,被协助的动词称作主要动词。
    构成时态和语态:助动词是语法功能词,自身没有词义,不可单独使用,它没有对应的汉译,
    例如:Hedoesn'tlikeEnglish.他不喜欢英语。(doesn't是助动词,无词义;like是主要动词,有词义)

  • 小学涉及到的助动词主要是do,以及它的两种时态:does和did。
    例:Does he work in the factory? 他是在这个工厂工作吗? 
        Do you have a pen? 你有一支钢笔吗? 
        He didn’t go to school yesterday. 他昨天没有去上学。

    助动词do 的用法:

    1)构成一般疑问句,例如:
    Do you want to pass the CET? 你想通过大学英语测试吗?
    Did you study German? 你们学过德语吗?
    2) do + not 构成否定句,例如:
    I do not want to be criticized. 我不想挨批评。
    He doesn't like to study. 他不想学习。
    In the past, many students did not know the importance of English. 过去,好多学生不知道英语的重要性。
    3)构成否定祈使句,例如:
    Don't go there. 不要去那里。
    Don't be so absent-minded. 不要这么心不在焉。
    说明: 构成否定祈使句只用do,不用did和does。
    4)放在动词原形前,加强该动词的语气,例如:
    Do come to my birthday party. 一定来参加我的生日宴会。
    I did go there. 我确实去那儿了。
    I do miss you. 我确实想你。
    5) 用于倒装句,例如:
    Never did I hear of such a thing. 我从未听说过这样的事情。
    Only when we begin our college life do we realize the importance of English.
    只有在开始大学生活时我们才认识到英语的重要性。
    说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
    6)用作代动词,例如:
    ---- Do you like Beijing? --你喜欢北京吗?
    ---- Yes, I do. --是的,喜欢。(do用作代动词,代替like Beijing.)
    He knows how to drive a car, doesn't he?
    他知道如何开车,对吧?

  • 基本助动词:
    be, do, have, 他们没有词汇意义,只有语法作用,如协助构成进行体,完成体,被动态,否定句,疑问句等。
    例如 He is giving a lecture. 他在作报告
    He has made a plan. 他已经订了计划
    The small animals are kept in the cages. 小动物都关在笼子里。

    助动词协助主要动词完成以下功用:
    a. 表示时态,例如:
    He is singing. 他在唱歌。
    He has got married. 他已结婚。
    b. 表示语态,例如:
    He was sent to England. 他被派往英国。
    c. 构成疑问句,例如:
    Do you like college life? 你喜欢大学生活吗?
    Did you study English before you came here? 你来这儿之前学过英语吗?
    d. 与否定副词not合用,构成否定句,例如:
    I don't like him. 我不喜欢他。
    e. 加强语气,例如:
    Do come to the party tomorrow evening. 明天晚上一定来参加晚会。
    He did know that. 他的确知道那件事。

考点名称:否定句

    a. 谓语为be动词时,“be+not "一名学生。

          He does not want to go to school. 他不想去上学。

    当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”的主语是第一人称,谓语动词为没有任何副词修饰的一般现在时,它们的否定式实际上是对宾语从句的否定。
    表示说话者提出一种委婉的看法或主张。如:
    I think that he will help us.——I don’t think that he will help us. 我认为它不会帮助我们。
    I believe that he is right.——I don’t believe that he is right. 我认为他不对。
    I suppose that he likes it.——I don’t suppose that he likes it. 我想他不喜欢它。

    2. 形式上否定谓语动词,实际上否定复合宾语
    当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”、“find”的主语是第一人称,谓语动词为没有任何副词修饰的一般现在时,它们前面的否定式实际上是对复合宾语的否定。表示说话者所提出的一种委婉的看法或主张。如:
    I think math difficult. — I don’t think math difficult. 我认为数学不难。
    I find the story interesting. — I don’t find the story interesting. 我认为这个故事没有趣。
    I expect so. —I don’t expect so. 我认为不会。

    二、动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”在下列情况下,否定不转移:
    1.这些动词跟其他另一个动词一起做并列谓语时,否定不转移。如:
    I believe and hope he won’t do that. 我相信并且也希望他将不会那样做。
    I feel and admit that we are not foolish. 我觉得并且也承认我们并不愚蠢。

    2.用于疑问句时,否定不转移。如:
