考点名称:系动词

  • 系动词:
    亦称连系动词,作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语,亦称补语(形容词),构成系表结构说明主语的状况、性质、特征等情况。
    be(是)是最基本的系动词。小学涉及到的系动词需要掌握的am, is, are 
    如:I am from Beijing. 我来自北京。 
    My mother is a teacher. 我的妈妈是一位老师。 
    除了系动词be,常用的系动词还有look(看起来)、sound(听起来)、feel(感觉到)、become(变成)、smell(闻起来)等。
    例:The boy looks very happy. 这个男孩看起来很高兴。 
            The dish smells good. 这盘菜闻起来很香。

  • be动词意思和用法:
    一般的意思是:
    是,此种用法,有多种变化形式,isamarewaswerebeingbeento be.
    另外,be动词还有成为的意思。
    根据句子中不同的人称、数和时态,应该选择相应的be动词。<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

    要看句语的时态:

    如果是一般过去时,就用was/were

    如果是一般现在时,就用am/is/are

    如果是一般将来时,就用will be

    然后看主语的人称及复数形式:

    一般过去时:

    第一人称和第三人称的单数形式,则用was

    第一人称和第二人称、第三人称的复数,则用were

    一般现在时:

    第一人称单数形式,用am

    第三人称单数形式,用is

    第一人称复数、第二人称、第三人称的复数形式,则用are

    一般将来时:

    will be

    一般时态有关be动词的口诀:

    我用am,你用areis连接他//它,复数形式就用are

     

    be动词的用法:
    现在时 I am, you are, he is, we are, you are, they are
    (缩略式 I'm, you're, he's, we're, you're, they're),
    (否定缩略式 I'm not, isn't, aren't),
    过去时 I was, you were, he was, we were, you were, they were
    (过去时否定缩略式 wasn't, weren't),
    过去分词been,现在分词being
    英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。
    “Be”除了原形的“be”之外,还有另外七种形式:
    am, is, are, been, being, was, were.
    在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)

  • 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:否定句

  • 否定句:
    表示否定的句子。必须有否定词。
    否定句的构成形式:
    a. 谓语为be动词时,“be+not "一名学生。
    b. 谓语为实义动词而且没有情态动词和助动词时,“do/ does/ did+not"构成否定。 
    例:I do not like dancing. 我不喜欢跳舞。 
          He does not want to go to school. 他不想去上学。
    c. 谓语为“情态动词+实义动词”时,“情态动词+not”构成否定。 
    例:You must not smoke. 你千万不要吸烟。 
           I can not catch it. 我抓不住它。

  • 否定句在英语语法中可以分为九类:
    (1)一般否定句
    I don't know this. No news is good news.
    There is no person(smoking)/not a person/not any person(smoking)in the house.
    (2)特指否定
    He went to his office, not to see him.
    I am sorry for not coming on time.
    I don't think/believe/suppose/feel/imagine you are right.
    (3)部分否定
    All the answers are not right
    All is not gold that glitters
    I don't know all of them.
    I can't see everybody/everything.
    Both of them are not right.
    (4)全体否定
    None of my friends smoke.
    I can see nothing/nobody.
    Neither of them is right.
    Nothing can be so simple as this.
    (5)延续否定
    You didn't see him, neither/nor did I.
    You don't know, I don't know either.
    He doesn't know English, let alone/to say nothing of/not to speak of(更不用说)French.
    (6)半否定句
    We seldom/hardly/scarcely/barely hear such fine singing.
    I know little English. I saw few people.
    (7)双重否定
    You can't make something out of nothing.
    What's done cannot be undone.
    There is no sweet without sweat.
    No gain without pains.
    I can't help /keep/ laughing whenever I hear it.
    No man is so old but(that)he can learn.
    (8)排除否定
    Everyone is ready except you.
    He did nothing but play.
    But for your help, I couldn't do it.
    (9)加强否定
    I won't do it at all.
    I can't see it any more.
    He is no longer a boy.

  • 否定转移的形式与用法:
    一、动词的否定转移
    1.形式上否定主句的谓语,实际上是否定从句的谓语
    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。
