3.22周三笔记
一、is/am/are was/were will be
句子中含有be动词，把be动词提前
二、句子中有情态动词
should,can,must,might,could
you should study hard------Should you study hard?
I must go to the clasroom on time ---- Must I go to the clasroom on time?
三、
He eats an apple everyday. 两类词都没有时，需要添加助动词：do，does，did
Does he eat an apple everyday
I eat an apple everdayDo I eat an apple everyday?
He ate an apple yesterdayDid he eat an apple yesterday?
(加了助动词后动词要变成原型)
所有疑问句都是疑问词在最前面
四、
当句子当中本身就有助动词时，把助动词提前,剩下地部分照抄
I have read 3 books.
Have I read 3 books
He has read 3 books
Has he read 3 books怎么区分：
看时态，一般现在时加do和does
过去时加did
加了助动词后边的动词要还原成原型，不加助动词就不需要把动词变成原型
怎么看时态：看动词
有be动词就把be动词提前，除答案外剩下的部分照抄
