    情态动词表推测用法总结及专项练习??
    1.can
    /
    could用于表推测的用法
    (1)
    从使用句型上看,can
    通常只用于否定句或疑问句,一般不用于肯定句,而could
    可用于肯定句、否定句和疑问句。两者没有时间上的差别,只是could

    can
    更委婉,更不确定。如:
    It
    can’t
    [couldn’t]
    be
    true.
    那不可能是真的。
    What
    can
    [could]
    they
    be
    doing?
    他们会在干什么呢?
    We
    could
    go
    there
    this
    summer.
    今年夏天我们可能要去那儿。
    注:can
    有时也用于肯定句中表示推测,主要用于表示理论上的可能性(即从理论上看是可能的,但实际未必会发生),或表示“有时”之意。如:
    Even
    experienced
    teachers
    can
    make
    mistakes.
    即使是有经验的教师也可能出错。
    She
    can
    be
    very
    unpleasant.
    她有时很令人讨厌。
    (2)
    从时间关系看,对现在或将来情况作推测,后接动词原形;对正在进行的情况作推测,后接
    be
    doing
    结构;对过去情况作推测,后接动词完成式。如:
    He
    could
    have
    gone
    home.
    他可能已经回家了。
    He
    can’t
    [couldn’t]
    have
    understood.
    他不可能理解了。
    Why
    does
    he
    know
    this?
    Can
    [Could]
    someone
    have
    told
    him
    about
    it?
    他怎么知道?
    会是哪个人告诉他了吗?
    (3)
    “could+完成式”除表示对过去的推测外,还有以下重要用法:

    表示过去没有实现的可能性,常译为“本来可以”。如:
    I
    could
    have
    lent
    you
    the
    money.Why
    didn’t
    you
    ask
    me?
    我本来可以借这笔钱给你的。你为什么不向我提出?

    用来委婉地责备某人过去应该做某事而没有去做,常译为“本来应该”。如:
    You
    could
    have
    helped
    him.
    你本来应该帮助他的。

    表示“差点儿就要”。如:
    I
    could
    have
    died
    laughing.
    我差点儿笑死了。
    2.
    may
    /
    might用于表推测的用法
    表示推测,两者都可用,只是
    might

    may
    语气更不确定,表示的可能性更小。
    (1)
    在句型使用方面:两者均可用于肯定句和否定句,但用于疑问句时,may通常不用于句首,但可用于疑问句的句中(如特殊疑问句等),而might尽管可以用于疑问句的句首,但不算普通,通常会改用其他句式(如用could等)。如:
    He
    may
    [might]
    know
    the
    answer.
    他可能知道答案。
    He
    may
    [might]
    not
    believe
    you.
    他可能不会相信你。
    And
    who
    may
    [might]
    she
    be?
    那么她会是哪一位呢?
    (2)
    从时间关系看,对现在或将来情况作推测,后接动词原形;对正在进行的情况作推测,后接
    be
    doing
    结构;对过去情况作推测,后接动词完成式。如:
    He
    may
    [might]
    tell
    his
    wife.
    他也许会告诉他妻子。
    He
    may
    [might]
    be
    writing
    a
    letter.
    他可能在写信。
    She
    may
    [might]
    have
    read
    it
    in
    the
    papers.
    她可能在报上已读到过此事。
    (3)“might+完成式”除表示对过去的推测外,还有以下重要用法:

    表示过去某事可能发生而实际上却并没发生。如:
    It
    was
    really
    very
    dangerous.
    I
    might
    have
    killed
    myself.
    那真的是太危险了,我差点没命了。
    A
    lot
    of
    men
    died
    who
    might
    have
    been
    saved.很多人本来可以获救的却死了。

    表示委婉的批评或责备。如:
    You
    might
    have
    made
    greater
    progress.
    你的进步本来可更大一些的。
    You
    might
    at
    least
    have
    answered
    my
    letter.
    你至少可以回我一封信嘛。
    3.
    must表示推测的用法
    must
    表示很有把握的推测,其意为“一定会”“肯定会”,只用于肯定句,一般不用于否定句或疑问句。表示对现在或未来的情况作推测,后接动词原形;表示对过去情况的推测,接动词完成式。如:
    I
    must
    be
    the
    happiest
    woman
    on
    earth!
    我一定是世界上最幸福的女人了。
    No,
    he
    must
    be
    lying.
    不,他一定在撒谎
    He
    must
    have
    mistaken
    my
    meaning.
    他一定误会了我的意思。
    4.
    should
    have
    done
    的用法
    should
    have
    done只用于谈论过去情况,主要有两个用法:一是用于推测过去已经发生的情况,二是用于指本该发生而实际上未发生的情况。如:
    You
    should
    have
    told
    me
    so
    before.
    你早就应该告诉我。
    He
    should
    have
    arrived
    by
    now.
    此时他本该到了。
    Look
    at
    the
    time!
    We
    should
    have
    been
    at
    the
    theatre
    ten
    minutes
    ago.
    瞧都什么时候了!
    十分钟前我们就该到戏院了。
    5.
    need
    have
    done
    的用法
    need
    have
    done结构主要用于否定句或疑问句,一般不用于肯定句。用于否定句时,表示本来不必做某事,但实际上却做了;用于疑问句时,用于询问某一过去动作的必要性。如:
    You
    needn’t
    have
    hurried.
    你当时实在不必那么匆忙。
    She
    needn’t
    have
    come
    in
    person

    a
    letter
    would
    have
    been
    enough.
    她本不必亲自来——写封信来就足够了。
    Need
    you
    have
    paid
    so
    much?
    你当时真须要付那么多钱吗?
    Need
    they
    have
    sold
    the
    farm?
    他们那时非得把农场卖掉不可吗?
    ?
    历届NMET中表推测的情态动词的用法
    情态动词是中学英语学习中的一个重点和难点,也是高考的重点考察内容之一。其中表示推测用法的情态动词在近几年的高考中更是屡见不鲜。现结合近几年的高考题目,对表推测的情态动词的用法作一归纳,希望对各位考生会有所帮助:
    【考例】1.
    Naturally,
    after
    I
    told
    her
    what
    to
    do,
    my
    daughter
    _____
    go
    and
    do
    the
    opposite!


      
    A.
    may
    B.
    can
    C.
    must
    D.
    should

    (2003年普通高等学校春季招生统一招生考试英语试题(安徽卷))
    【分析】Can,may,must都可用来表示”推测”,但侧重点各有不同:
    May常用来指”事实上的可能性”,而can则表示一种”理论上的可能性
    ”例如:
    The
    railways
    may
    be
    improved.
    =It
    is
    possible
    that
    the
    railways
    will
    be
    improved.
    =Perhaps/Maybe/Possibly
    the
    railways
    will
    be
    improved.
    铁路可能会得到改进。(意味着已有具体的改进计划或方案。)
    The
    railways
    can
    be
    improved.=It
    is
    possible
    for
    the
    railways
    to
    be
    improved.
    铁路可以得到改进。(意思是铁路还不完善,尚有问题存在。)
    理论上的可能性(can)比事实上的可能性(may)更弱。
    在一般的陈述句,can与sometimes几乎相同,表示一种偶然的可能性。比如:
    Even
    expert
    drivers
    can
    make
    mistakes.甚至是很熟练的驾驶员也可能会犯错。
    =Even
    expert
    drivers
    sometimes
    make
    mistakes.
    =It
    is
    possible
    for
    the
    expert
    drivers
    to
    make
    mistakes.
    因此,如果讲的是一种特殊情况,不是一般情况,就用may,试比较:
    Mr
    Reed
    looks
    pale.He
    may
    be
    ill.
    Mr
    Reed
    is
    in
    poor
    health.He
    can
    be
    ill
    at
    any
    time.
    Must指逻辑必然,作“想必”、“准是”、“一定”解,用来表示我们对某事有把握的推论或揣测。(考虑到迹象如此,再无别的结论=It
    seems
    certain
    that….):
    They
    must
    be
    very
    tired
    now,
    for
    they
    have
    been
    working
    the
    whole
    morning.他们现在一定是非常累了,因为他们整个上午都在工作。
    析:填C.must。意思是”不出所料,当我告诉女儿要做的事时,她准会去做相反的事。”
    【考例】1、Mary
    ___
    be
    in
    Paris.I
    saw
    her
    in
    town
    only
    a
    few
    minutes
    ago.(NMET1994) 
    A.mustn’t
    B.shouldn’t
    C.can’t 
    D.may
    not
       
    2、.--Is
    John
    coming
    by
    train?
    (NMET
    2002
    Tianjing
    )
     
    --He
    should,but
    he
    ___
    not.He
    likes
    driving
    his
    car.
    A.must
    B.can
    C.need
    D.may
    【分析】May用于否定时,not不是否定may,而是否定句中的动词,这一点与can不同,试比较:
    He
    may
    not
    know
    the
    truth.他可能不知道事情的真相。(=It
    is
    possible
    that
    he
    didn’t
    know
    the
    truth.)
    He
    cannot
    know
    the
    truth.他不可能知道事情的真相。
    must表示推测的这种用法通常用在肯定句中,在疑问句中常用can(可能),在否定句中常用can’t(不可能,不会是),而不用mustn’t。例如:
    ---
    Somebody
    is
    knocking
    at
    the
    door.
    Who
    can
    it
    be
    ?
    It
    must
    be
    Wang
    Hong.
    ---
    No,
    It
    can’t
    be
    Wang
    Hong,
    because
    she
    left
    for
    Shanghai
    this
    morning.
    ---
    有人在敲门。会是谁呢?一定是王红。
    ---不,不会是王红,因为她今天早晨就动身去上海了。
    因而You
    must
    be
    joking.在意义上相当于You
    can’t
    be
    serious.
    析:1、填C。意思是”玛丽不可能在巴黎。几分钟前我还看见她在镇上。2、填D。意思是”--约翰会坐火车来吗?--应该会,但他可能不会。他喜欢开车。”
    【考例】1.---I
    heard
    they
    went
    skiing
    in
    the
    mountains
    last
    winter.
    (NMET
    2002Beijing
    )
     
       ---It
    ___
    true
    because
    there
    was
    little
    snow
    there.
     
    A.may
    not
    be
    B.won't
    be
    C.couldn't
    be 
    D.mustn't
    be

    【分析】Could,might表示过去的可能性。
    I
    thought
    it
    might
    be
    true.我本认为那是真的。
    He
    could
    be
    very
    unreasonable.他有时可能毫不讲理。
    析:填C。它是对去年冬天所发生的事进行评价。
    【考例】1.--Are
    you
    coming
    to
    Jeff’s
    party?
    (NMET
    2000)



    --I’m
    not
    sure.I_____go
    to
    the
    concert
    instead.  
    A.must 
    B.would 
    C.should 
    D.might

       
    2.---Look!The
    clouds
    are
    gathering.



    ---Yes.I'm
    afraid
    it
    _____
    be
    pouring
    down
    soon.

      
    A,can
    B,must
    C,should
    D,might
    【分析】could和might表示现在的情况时,更带有不肯定性和慎重味道,构成礼貌或婉转说法,包含或许的意思:
    A:I
    wonder
    where
    Tom
    is.
    B:He
    may/might/could
    be
    in
    the
    library.(Perhaps
    he
    is
    in
    the
    library.)因此在wonder,
    fear,be
    afraid等后接的从句中,通常用may/might/could,表达一种探询的观点:
    I
    was
    afraid
    you
    might
    be
    out
    of
    sorts.我怕你可能心情不痛快。
    假设性的可能和试探性的可能,也用could和might:
    Our
    team
    might
    still
    win
    the
    race.(可以意译为:It
    is
    possible,though
    unlikely,that
    ……)
    析:1、2均填D.might
    【考例】Mr.
    Bush
    is
    on
    time
    for
    everything.
    How
    _________
    it
    be
    that
    he
    was
    late
    for
    the
    opening
    ceremony?
     A.can
      B.should  
    C.may  
    D.must
    (2001年上海普通高校春季招生考试试卷)
    【分析】表示推测的may通常不用于一般疑问句,而要用can代替。Can用于一般疑问句时,还可表示惊讶或怀疑,意思是”(到底)可能有这样的事吗?”,比如:
    “There
    is
    the
    doorbell.””Who
    can
    it
    be
    at
    this
    time
    of
    day?”有人按门铃。””这个时候到底会是谁呢?”
    Must也偶尔用于疑问句:Must
    there
    be
    some
    good
    reason
    for
    the
    delay?这个问句设想的是一个肯定的回答,可以解释为”Does
    there
    have
    to
    be
    some
    good
    reason……?”
    may可用于特殊疑问句或wh-从句,意思是”(到底)是…”、”不知是否
    …”:
    I
    wonder
    what
    it
    may
    mean.我不知道这究竟是什么意思。
    How
    old
    may
    his
    father
    be?他父亲到底有多大年纪?(比How
    old
    is
    his
    father?委婉的说法。)
    析:填1、A.can.(布什先生做什么事都很按时。他怎么可能会在开幕式上迟到呢?)
    【考例】1.
    Sorry
    I'm
    late.
    I
    ________
    have
    turned
    off
    the
    alarm

    be 
    C.mustn't
    have
    been   D.couldn't
    have
    been
    【分析】“情态动词have
    +
    -ed分词”结构可以表示对已发生的事情进行推测,
    就表示的可能性程度而言,must最大,could其次,may更次之,might最小。
    must
    +
    have
    +
    -ed分词:
    用于肯定句,
    表示推测过去某事“肯定,一定,准是”发生了。
    其否定形式为:can’t
    /
    couldn’t
    have
    v-ed,
    表示过去不可能发生某事。
    may(might)
    +
    have
    +
    -ed
    分词:
    用于肯定句和其他否定句
    ,
    表示对已发生事情的不肯定的推测,
    意为“可能,
    大概”,
    其中might较may语气更弱,
    把握更小。Can/could用于否定或疑问句中,表示对过去发生的事件的“怀疑或不肯定”。could
    比can更表示说话人语气的不肯定。例如:

    I
    mailed
    that
    letter
    a
    week
    ago.
    He
    must
    have
    received
    it.我一周前就发出了那封信,
    想必他一定收到了。
    I
    can’t
    find
    my
    keys.
    I
    may
    /
    might
    have
    left
    them
    at
    the
    school
    yesterday.
    Jack
    can’t
    have
    arrived
    yet,otherwise
    he
    would
    have
    telephoned
    me.(上海1997)
    It
    couldn't
    have
    been
    Mr.
    Smith.
    He
    has
    gone
    to
    China.不太可能是史密斯先生。他已去了中国。
    另外,注意may不可用于疑问句,它的这种功能已为can所取代。例如Can
    they
    have
    missed
    the
    bus?的答句是:Yes,they
    may
    have
    done.而不是Yes,they
    can
    have
    done.这一点要注意。
    Must偶尔也能用于否定句:His
    absence
    must
    not
    have
    been
    noticed.此句和His
    absence
    can’t
    have
    been
    noticed.的意思是一样的。许多评论者认为这类句子是不可能成立的,但它们正在为越我来越多的人所接受和使用,在美国英语中尤其如此。
    对正在发生的事情进行推测,则采用”情态动词+be+现在分词”结构,其中情态动词的区别与上相同。
    析:答案A、D。can通常不用于肯定句表猜测;”should+have+-ed
    分词”表示”过去本来应该做……”,但实际上没有做,意思是”本该…..”,带有责备口气:I
    was
    really
    anxious
    about
    you.You
    shouldn’t
    have
    left
    without
    a
    word.
    (NMET2001)
    ;”will+have+-ed分词”只是将来完成时的一种形式。
    【考例】1.It's
    nearly
    seven
    o'clock.
    Jack
    ____be
    here
    at
    any
    moment.
    (NMET95)
     


    A.must   
    B.need

    C.should
    D.can

    【分析】should(ought
    to)表示很可能、预期的意思,指一种尝试性推论,可认为是must的语气较弱的对应词,意思是”应该会、一定。。。吧”。试比较:
    Our
    guests
    must
    be
    home
    by
    now.(‘I
    am
    certain’)我们的客人现在一定到家了。(根据他们动身的时间、路程远近、速度等具体条件,我能断定/肯定他们现在已经到家了。)
    Our
    guests
    should(ought
    to)
    be
    home
    by
    now.(‘They
    probably
    are,but
    I’m
    not
    certain.)我们的客人现在该到家了。(含义是我想他们很可能到家了,但我不能肯定”)
    与must不同还在于它常常表示将来:
    --When
    can
    I
    come
    for
    the
    photos?I
    need
    them
    tomorrow
    afternoon.
    --They_____be
    ready
    by
    12:00.
    (NMET1998)
    A.can
    B.should
    C.might
    D.need表示不太可能可用shouldn’t(oughtn’t
    to):
    There
    shouldn’t(oughtn’t
    to)
    be
    any
    difficulties.不该有任何困难。
    析:填C。意思是”将近七点了。杰克很可能随时会到。” 
    另外,在近几年的NMET中,对情态动词及其它语法项目的考查均放到一定的语境中进行,要求考生利用所学英语各项基础知识进行初步的语言运用,而不再是单纯的语法知识题和短语题。这类试题往往通过题干的其他部分或附加句子提供某个信息,然后让考生根据这个信息进行合理推理,产生新的想法和认识。因此,在做这类题时,除要熟悉所考查的语法规则外,还要认真分析句子的结构,注意抓住关键词,分析上下文的逻辑关系。不能单凭语法规则做题。
