一般现在时则多用来表示一贯的,习惯性的发生的事情
一般过去时讲的是过去发生的事情
WHAT WERE YOU DO THIS MONING?过去时
应该是what were you doing this morning
因为句子里不可以同时有be动词和实义动词,did是助动词,也就是说,是要帮助实义动词的。后面直接动词原型就可以。而were/was后面都要加上动词的现在分词(进行时)或者过去分词(被动语态)。一般现在时表示现阶段发生的动作或状态,以及永恒不变的事实、真理和自然规律,常与时间状语today, every day, on Sunday, every morning等连用。
What day is today ?
We sometimes go to the park on Sunday.
They ride bikes to school every day.
I get up early every morning .
Spring returns in March.
He said spring returns in March..
The sun is bigger than the moon .
一般过去时表示过去阶段发生的动作或状态,常与时间状语yesterday,last year, the day before yesterday , the month before,this morning,five days ago等连用。
What day was yesterday ?
We sometimes went to the park on Sunday last year .
They rode bikes to school the day before yesterday.
