1、中学英语情态动词专项练习题中学英语情态动词用法归纳情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必需跟动词原形；考点一： can， could, may ，must等情态动词的用法：1. can 的用法：（ 1） .表示才能、许可、可能性；表示才能时一般译为“能、会 ”， 即有种才能，特别是生来具备的才能，此时may 和 must 均不行代替它；如：she can swim fast, but i can她能t . 游得很快，但我不能；i can see with my eyes.我用眼睛看；（ 2） .表示许可，常在口语中

8、day， didn t you.注意反意疑问句的后半部分5. need 的用法：（ 1） .need 表示需要、必需，主要用于否定句和疑问句中，其否定形式为needn，t意为 “没有必要，不必 ”； 用 need 提问时，确定回答为must，否定回答为needn或t dont have t；o如： need i stay here any longer.我仍有必要留在这儿吗？yes, you must . 是的； no. you needn t /don t ha不ve，to.你不必；2.need 仍可以作实义动词，此时有人称、数和时态的变化，假如是人作主语后边多接动词不定式；如： i nee

9、d to do it right now.我需要立刻做这件事；he needs to learn more about the girl. 他需要多明白那个女孩；假如是物作主语，一般用need doing与 need to be done 这种情形下应留意两点： .主动形式的动名词doing 具有被动的含义；.该动名词可以改为其动词不定式的被动形式而句子的意义不变；例如：. the door needs painting. = the door needs to be painted.那扇门需要油漆一下；your car needs mending. = your car needs to b

10、e repaired. 你的车需要修理了；6. dare 的用法： dare 意为 “敢、敢于 ” ,用法近似于need，有两种词性：（ 1） dare 作为情态动词，多用于否定句、疑问句或条件句中，无第三人称单数形式，只有一般现在时和一般过去时；如： dare he tell them what he knows.他敢告知他们所知道的情形吗？i daren t ask herwill you do it for me.我可不敢问她，你能帮我问问吗？（ 2） dare 作为实义动词，此时有人称、数准时态的变化；中学英语情态动词专项练习共十页；第 2页如： he doesnt dare to b

13、nother day.(4). 用“ would you like. ”来提出建议，意思是“你想要吗.” would you like 后可接名词或不定式；如：would you like a cup of tea.would you like to go and see her.因此，假如我们说：“去游泳好吗 .”英语中可有这样几种表达法： shall we go for a swim. let's go for a swim ， shall we. what about/how about going swimming. why not go for a swim. would y

16、next week.肯定不能说： there will have a sports meeting next week.2、will与 be going to do sth 区分：中学英语情态动词专项练习共十页；第 3页 . be going to表示近期、眼下就要发生的事情，will表示的将来时间就较远一些，如： he is going to write a letter tonight. he will write a book one day. . be going to表示依据主观判定将来确定发生的事情，will表示客观上将来势必发生的事情；he is seriously ill. h

17、e is going to die.he will be twenty years old. . be going to含有“方案，预备”的意思，而will就没有这个意思，如：she is going to lend us her book.he will be here in half an hour. .在有条件从句的主句中，一般不用be going to,而多用 will,如：if any beasts comes at you, i'll stay with you and help you10. had better 的用法：had better最“好 ”，没有人称和数的变化
