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:一般过去时,动词过去式

    • 一般过去时:
      表示过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为;过去主语所具备的能力和性格。
      be动词在第一人称是单数和第三人称是单数是用was,其余用were。
      a. 表示在过去时间里所发生的动作或存在的状态,常与表示过去的时间状语。
      yesterday(昨天)、last week   (上星期)、an hour ago(一小时前)等连用。 
        例:I went to the zoo with my father last Sunday. 上周日我和我爸爸去动物园了。
           They weren't able to come because they were so busy.他太忙了,所以去不了。
      b. 表示在过去一段时间里,经常性或习惯性的动作或状态。 
        例:My brother watched the World Cup every day last month.上个月哥哥每天都看世界杯比赛。

    • 一般过去时句法结构:
      肯定形式
      主语+动词过去式+其他
      例句:She often came to help us in those days.

      否定形式
      ①was/were+not;②在行为动词前加didn't,同时还原行为动词
      例句:I didn't know you like coffee

      一般疑问句
      ①Did+主语+do+其他? ②Was\Were+主语+表语?
      例句:Did I do that?
      用表格整理如下:
      肯定式 疑问式 否定式 疑问否定式
      Iworked Did I work? I did not work Did I not work?
      He(She,It) worked Did he(she,it) work? He(she,it) did not work Did he(she,it) notwork?
      We worked Did we work? We did not work Did we not work?
      You worked Did you work? You did not work Did you not work?
      They worked Did they work? They did not work Did they not work?

      结构句型:
      1.一般句子
      I watched TV last night.
      2.一般疑问句
      Did you watch TV last night?
      3.there be 句型
      There was an apple on the table last night.
      Was there an apple on the table last night

    • 一般过去时用法口诀:
      一般过去时并不难,过去动作、状态记心间。
      动词要用过去式,时间状语句末站。
      否定句很简单,didn't 站在动原前,其它部分不要变。
      一般疑问句也好变,did放在句子前,主语、动原、其它部分依次站。
      特殊疑问句也简单,疑问词加一般疑问句记心间。
      最后一条请注意,动词过去式要牢记!

    考点名称:动词不定式

    • 不定式定义:
      由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词,可分为不定式,动名词,现在分词和过去分词。
      “动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。
      常见的有:like / love,want,need,ask,help等。
      例:I like to play with Tom. 我喜欢和汤姆玩。 
              I want to play with Tom. 我想和汤姆玩。 
              I like to eat dumplings. 我喜欢吃饺子。

    • 动词不定式一般结构:
      疑问词who,what,which,when,where,whether,how后可接不定式构成不定式短语,在句中作主语、宾语、表 语等。如:
      ①When to leave for London has not been decided yet. (不定式在句子中做主语)
      ②Mr. Smith didn't know whether to leave or stay there. (不定式在句子中做宾语)
      ③I asked Professor Xu how to learn English well. (不定式在句子中做直接宾语)
      ④The question was where to get the medicine needed. (不定式在句子中表语)
      以上例句中疑问词+不定式部分,均可转换为相应的从句形式。如:
      ①When we shall leave…
      ③…how I could learn…
      经常在这种结构中使用的动词有:
      consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。

    • 动名词与不定式的区别:
      1 动名词与不定式的区别:
      动名词表达的是:状态,性质,心境,抽象,经常性,已发生的 
      不定式表达的是:目的,结果,原因,具体,一次性,将发生的

      2 接不定式或动名词,意义相同。

      3在下列情况下,一般要用不定式:
      ①hate,like,love前有would(should)时,
      如:I'd like to have a cup of coffee.
      ②当谓语动词begin,continue,start等是进行式时,
      如:Thestudents are starting to work on the di fficult maths problem.
      ③begin,continue,start与know,understand等状态动词连用时,
      如:I soon began to understand what was happening.
      ④.advise,allow,encourage,forbid,permit等动词后接动名词作宾语,或带不定式作宾语补足语。如:
      Our teachers don't permit our/us swimming in the lake.
      Our teachers don't permit us to swim in the lake.

      4 部分动词后接不定式或动名词时,意义差别较大,应根据句子语境选择使用。
      forget,remember,regret后接不定式,表示现在或未来的动作,接动名词表示动作已经发生。如:
