小学英语常考情态动词及习题练习

小学常考情态动词（can,must,should,might）及习题情态动词:情态动词本身具有一定的词义，表示说话人的某种语气或感情，但不能单独作谓语，通常要和行为动词一起构成谓语。情态动词没有人称和数的变化，适用于所有人称，其后要接动词原形。一、情态动词can的用法：1、其中情态动词can表能力时意为“能够做某事”，后接动词原形；否定形式为can't或cannot；can的过去式为could。例：1.Tonycanplaybasketball,buthecan'tplaythepiano.Tony会打篮球，但他不会弹钢琴。2.CanLilyspeakChinese?—Lily会说中文吗？-Yes,shecan.—是的，她会。3.Whatcanyoudo,Kate?—Kate，你会做什么？-Icanplaytheviolin.—我会拉小提琴。其中情态动词can表许可或请求别人的许可时，意为“可以”，后接动词原形，相当于may，但may多用于正式、庄重的场合；can的否定形式为can't或cannot。例：Youcangonowifyoulike.如果你想走，现在就可以走了。-Mark,canIuseyourpen?

—Mark，我能用下你的钢笔吗？-Ofcourse.

—当然了。二、情态动词must表示“必须，应该，一定要”。l

主语是第一人称I或we时，表示说话人认为有必要或者有义务做某事；主语是第二、第三人称you、they、he、she等时，表示说话人要求或命令别人做某事。l

must的否定形式为mustnot，缩写为mustn't，意为“不许；严禁”。l

must引导的一般疑问句，肯定回答用must，否定回答用needn't或don'thaveto，意为“不必”。例：Timeisup.Wemustleavenow.时间到了。我们现在必须离开了。Hemustreturnthedictionarytomorrow.他明天必须归还那本词典。Childrenmustnotplaywithfire.儿童不准玩火。-MustIfinishtheworktoday?-No,youneedn't/don'thaveto.—我今天必须完成这项工作吗？—不，你不必。三、情态动词should意为“应该”，其否定形式是shouldn't“不应该”。should主要有以下两种常考用法：（1）should表示不可推卸的义务或责任。例：Thepoliceshoulddosomethingabouttheaccident.警方应该就那场事故采取一些行动。Weshouldn'tlaughatothers.我们不应该嘲笑他人。（2）should表示建议或劝告。例：Youshouldreadhisnewbook.

你应该读一读他的新书。Peopleshouldexercisemore.人们应该多锻炼。四、情态动词must和might均可表推测。但其用法有所不同。（1）must表示对事物的推测，意为“一定，肯定”，只用于肯定句中。例：Thelightison.He

must

beathome.

灯亮着呢。他一定在家。

Yourmothermustbewaitingforyounow.

你妈妈现在肯定在等着你呢。（2）might是may的过去式。might表示推测，意为“可能，也许”，推测的可能性较低。表推测时，might既可用于肯定句，也可用于否定句。例：Hesaidhemightbelate.

他说他可能会迟到。Shemightnotwanttocomewithus.她可能不想和我们一起去。小学常考情态动词（can,must,should,might）习题一、单选题1.-CanyousingthesonginEnglish?-No,I______.A.can't
