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.

    • 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。
      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。
