  • 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:量词

    • 量词:
      用来表示人、事物或动作的数量单位的词。
      如:a bottle / glass of,a cup of,a piece of,a pair of

    • 量词词组特点:
      特点一:
      英语量词词组所表示的数或量,大致可归纳为四种类型,即定量、不定量、大量和少量。
      1.表示定量的量词词组,譬如:
      a couple of(两个、一对)
      a couple of days,
      a couple of players,
      a couple of times;
      a cupful of(一满杯)
      a cupful of jelly,
      a cupful of water;
      a portion of(一份/客)
      a portion of duck,
      a portion of roast beef.
      2.表示不定量的量词词组,譬如:
      a majority of(大多数/大半)
      a majority of opinions,a majority of votes;
      an atom of(一点)
      an atom of food,an atom of truth;
      a spell of(一阵/一段时间)
      a spell of fine weather,
      a spell of coughing.
      3.表示大量的量词词组,譬如:
      a flood of—a flood of ink(洋洋大篇),
      a flood of tears(泪如泉涌);
      a heap of—a heap of earth(一堆泥土),
      a heap of customers(许多顾客);
      a mountain of—a mountain of debts(债台高筑),
      a mountain of difficulties(困难重重).
      4.表示少量的量词词组,譬如:
      a drop of—a drop of fever(有点热度),
      a drop of dew(一点露水);
      a particle of—a particle of feeling(一丝感情),
      a particle of dust(一点灰尘);
      a shadow of—a shadow of doubt(一点怀疑),
      a shadow of freedom(一点自由).

      特点二:
      有些数量词组修饰可数名词,有些数量词组修饰不可数名词,还有些则两者均可修饰。
      1.修饰不可数名词的量词词组,譬如:
      a bit of—a bit of English(一点英语),
      a bit of good advice(一些好意见),
      a bit of interest(一点兴趣),
      a shred of—a shred of evidence(一点证据),
      a shred of cloth(少量布),
      a shred of reputation(一点声誉),
      a sheet of—a sheet of glass(一块玻璃),
      a sheet of water(一片汪洋)。
      2.修饰可数名词的量词词组,譬如:
      a cluster of—a cluster of flowers(一簇花),
      a cluster of spectators(一群观众),
      a cluster of bright stars(闪烁群星),
      a string of—a string of pearls(一串珠子),
      a string of curses(连续不断的咒骂),
      a string of excuses(一连串借口),
      a scram of—a scram of mosquitoes(一群蚊子),
      a scram of geese(一群鹅),
      a scram of children(一群孩子)
      3.修饰(不)可数名词的量词词组,譬如:
      a body of—a body of bees(一群蜜蜂),
      a body of cold air(一股冷空气),
      a body of facts(许多事实),
      a block of—a block of ice(一大块冰),
      a block of flats(一幢公寓),
      a block of houses(一排房子),
      a chain of—a chain of ideas(一系列想法),
      a chain of accidents(一连串事故),a chain of proof(一连串证据)。

      特点三:有些数量词组的搭配是固定的,而有些搭配则比较灵活。
      1.搭配固定的量词词组,譬如:
      a barrel of—a barrel of beer(一桶啤酒),
      a barrel of crude oil(一桶原油),
      a basket of—a basket of eggs(一篮鸡蛋),
      a basket of apples(一篮苹果),
      a line of—a line of trees(一行树),
      a line of poetry(一行诗)。
      2.搭配较灵活的量词词组,譬如:
      a piece of—a piece of paper(一张纸),
      a piece of furniture(一件家具),
      a piece of equipment(一台设备),
      a round of—a round of spirit(一巡酒),
      a round of diplomatic talks(一轮外交谈判),
      a round of toast(一片烤面包)
      a bar of—a bar of chocolate(一块巧克力),
