据人称和单复数的不同而有字形的变化.第一第二人称,以及第一.二.三 人称的复数时,都用 do . 第三人称单数时,用 does( he does she does it does ) 例如: I do my homework on Sunday. You do your homework on Sunday. We do our homework on Sunday. You do your homework on Sunday. They do their homeworkon Sunday. He does his homework on Sunday. She does her homework on Sunday.

否定形式是don't,doesn't

1.she does"t play basketball

或者是这样。。used to do sth. 句型表示“过去常常,过去习惯。”表示过去的某种习惯(过去经常反复发生的动作或状态)。 e.g. I used to live there when I was a child. n 否定式:used not to do sth. 口语中:didn’t use to do sth. (used not可缩写为usedn’t或usen’t.) e.g. I used not to live there when I was a child. I didn’t use to live there when I was a child. 疑问句:used sb. to do sth.? Did sb. use to do sth.? e.g. Used you to live there when you was a child. Did you use to live there when you was a child? used to do sth.与be used to (doing) sth.的区别 1. used to do sth. “过去总做某事”(现在不做了)只用于过去时态。 e.g. He used to get up early. 2. be used to (doing) sth. 表“习惯于做某事”,可用于现在、过去、将来的多种时态,be可以用become, get等来代替,此处to是介词。

如果人稱是第三人稱單數,則用does,如he she it 是單數a plane等等的名詞都是屬於單數,還有不可數名詞後面也用單數,即是用does,否定式則是doesn't,如果不是第三人稱單數則不用does,用do

dose 是do 的单数第三人称,他们的否定形式分别是:dosen't、don't,只有在第三人称代词:it ,he/she,they等后面用dose,其它的用do。例如:

Do you like the moon cake I give you.

He doesn't like swiming.

do:第一第二人称(I, we,you) 和第三人称复数(they)如:Do you like the pencil?

does :第三人称单数(he , she ,it )如:Does he look like a superman ?

do>>>don't does >>>doesn't
