2017-04-06
区别如下:
一般过去时:
概念:过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为.
时间状语:ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time等。
基本结构:①be动词;②行为动词
否定形式:①was/were+not;②在行为动词前加didn't,同时还原行为动词.
例如:
I was student ago. (be动词过去式)
I bought the book yesterday.(行为动词buy过去式)
I didn't buy the book yesterday. (行为动词否定形式)
现在进行时:
概念:表示现阶段或说话时正在进行的动作及行为.
时间状语:now, at this time, these days等。
基本结构:am/is/are+doing
否定形式:am/is/are+not+doing
例句:
I am doing my homework now.(be+动词的ing)
He is not watching TV now.(be动词的否定形式)
一般现在时:
概念:经常、反复发生的动作或行为及现在的某种状况.
时间状语:
always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, 等。基本结构:①be动词;②行为动词
否定形式:①am/is/are+not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词.
例句:
I always go to library every week.(行为动词)
He often don't brush teeth.(行为动词的否定形式)
一般将来时:
概念:表示将要发生的动作或存在的状态及打算、计划或准备做某事.
时间状语:tomorrow, next day(week, month, year…),soon, in a few minutes, by…,the day after tomorrow, 等。
基本结构:①am/is/are/going to + do;②will/shall + do.
例句:
He is going to read many book next week.(be动词+going to do)
We shall visit the Great Wall next Sunday.
