情态动词can的用法
can是情态动词+动词原形.有三种用法:
1.表示:“会、能” 例如:
I can swim.我会游泳.
The question is easy ,I can answer it easily.这个问题简单,我能容易的答出来 .
2.表示请求、允许, 例如:Can I help you?
有时可以与may 互换. 例如:
Can/May I sit here? 我可以坐这吗? 但can多用于口语,而may较正式.
3.表推测.
The book can be Li's.这本书可能是李的.表推测时与must(一定)相比语气要弱些.例如:
The book must be Wang’s, her name is on it.这本书一定是王的 ,上面有她的名字.
另外,还有固定搭配:can't help doing 禁不住做某事
句型构成
肯定句: 主语+can+动词原形+其他。
否定句:主语+can’t+动词原形+其他。
疑问句:Can+主语+动词原形+其他?
肯定回答:Yes,主语+can。
否定回答:No,主语+can’t.
注意:
1.can’t =cannot 中间无空格
2.在变否定句和疑问句时主语不变,只有在回答时才用相应的人称代词代替。
3.当主语是第一人称(I, We )时,变疑问句时要把第一人称(I, We)改为第二人称You。
4.Can 没有人称和数的变化后面永远加动词原形。

一般将来时be going to
构成
肯定句: 主语+ be going to + do
否定句: 主语+ be+ not+ going to +do
一般疑问句: be+主语+going to+do
特殊疑问句: 疑问词+be+主语+going to+do
用法
be going to + do常用来表达自己打算做某事、计划做某事或者有意做某事。注意:be 动词要与主语的人称和数一致,如:
I am going to do some reading tomorrow.
He is going to have a piano lesson next week.
We are going to have a party this Friday.
常用的时间状语:
tomorrow, next day (week, month, year…), soon, the day after tomorrow(后天)等
be going to 和will的区别
通常情况下will 和 be going to能互换,但是be going to 与will 用法的也是有点区别的
1. 只用will不用be going to的情况:
①表示对未来时间与年龄的推测时,如: Tomorrow will be Monday. She will be thirteen next year.
②表示必然发生时,如:Fish will die without water. People will die if all green plants die.
2.只用be going to而不用will的情况:如果表示已有迹象表明在不久的将来要发生的事情时,如:Look at those black clouds, It’s going to rain.
