  从零开始学语法:情态动词can与may的.用法

  can的用法

  一、表能力,有“能,会,能够”的意思。例如:

  -Canyoudriveacar?你会开车吗?

  -Yes,Ican.我会。/No,Ican't.我不会。

  二、表允许,在口语中代替may,有“可以”的意思。

  (见下面may的用法第四点)

  三、表示可能性,常用于否定句和疑问句。例如:

  Canitbetrue?那会是真的吗?

  TodayisSunday.Hecan'tbeatschool.今天是星期天,他不可能在学校里。

  很多同学都不太清楚can与beableto的异同吧,赶快来学习一下吧>>

  may的用法

  一、表示许可或征求对方的许可,有“可以”的意思。例如:

  Youmaygonow.你可以走了。

  MayIuseyourcomputer?我用一下你的电脑可以吗?

  二、回答以may开头的疑问句有如下表达法:

  -MayIsmokehere?我可以在这儿抽烟吗?

  -Yes,youmay./Yes,please.请抽吧。

  -No,youcan't./No,youmustn't./No,you'dbetternot.请不要抽烟。

  三、表示猜测,通常只用于陈述句。例如:

  Youmayberight.你可能是对的。

  四、在口语中can可以代替may表示许可,但can较随便,may更正式。例:

  CanIuseyourbike,John?约翰,我可以用一下你的自行车吗?

  MayIhavealookatyourlicenseplease,sir?先生,我可以看一下你的执照吗?

  从零开始学语法:情态动词must与haveto的用法

  Youmusttalktothemabouttheirstudy.你必须同他们谈谈关于他们学习的事。

  二、在否定结构中表不许。例如:

  Youmustn'tleavehere.你不能离开这儿。

  三、表推测,暗含有很大的可能性。例如:

  Hemustbeill.Helookssopale.他肯定是病了。他的脸色那么苍白。

  注意:之前我们说过may也可以表猜测,但是may暗含的可能性较小,must暗含的可能性较大。另外否定的猜测是用can't。例如:

  Thebabycan'tbeill.Heissoactive.那宝宝不大可能是病了。他那么活跃。

  四、表不可避免,“必然要,必定会”。例如:

  Allmenmustdie.人总有一死。

  五、表主张,“坚持要,一定要”。例如:

  Imuststudyhard.我必须努力学习。(主观上认为应该努力学习)

  二、在疑问句和否定句中,haveto多用助动词do构成,must则直接提前或加not。例如:

  Didhehavetodoit?=Musthedoit?他得做那件事吗?
