英语can的使用特点?后面应加什么?动词原形?

can有两个完全不同的意思,共同学习
一、n.1.金属罐 oil-can,milk-can,
2.(从前用于美国,现在亦用于英国)不透空气的白铁罐,罐头,罐头之内容 a can of beer,
3.(us.sl)监狱,牢房
vt.1.装（食品等）于罐头,罐装 canned fish,canned music
cannerey n 罐头工厂,装 罐工厂
二、情态动词
1.能、会,eg.Can you lift this box?
2.与感官动词连用,eg.Ican hear people talking in the next room.
I can see a sail on the horizon.
3.用于口语,表许可,eg.You can go hone now.The children asked whether they could go for a swim.
4.can或could 用以表示可能性,eg.One of prisoners escaped yesterday-he can/could be anywhere by now.
5.can 或could在问句中,尤其与what,whatever,where how连用时,表示惊奇、困惑、不耐烦等,视上下文而定,eg.Where can they have got to
6.can 或could表示被视为特性者,某人或某事物之能力.常用表示次数之副词,如at times,sometimes,
eg.Children can sometimes be very tiring.When I first knew her she could be very sarcastic,but she's more tolerant now.
7.could用于指‘想要’之意,eg.i could smack your face!
8.can用于有命令意谓的口语中,表示‘必须’,eg.Tell Mr Evans that he can come in now,
9.can 或could 用于礼貌的请求,eg.Do you think i could leave now?

can 一般做情态动词,能,可以,后接动词原形
补充三个,不常用的,
做及物动词:装进罐中, 把食品装罐
做名词:罐头, 铁罐
连词,conj.能, 可以

动词原形,can是情态动词,它后面加的动词都必须是原形
