为了中考的英语能考好点,帮帮我拉~~~^-^

一、 一般现在时:

1.概念:经常、反复发生的动作或行为及现在的某种状况。

2.时间状语: always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays,

3.基本结构:动词 原形 (如主语为第三人称单数,动词上要加(e)S)

4.否定形式:am/is/are+not;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。

5.一般疑问句:把be动词放于句首;用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。

6.例句:. It seldom snows here.

He is always ready to help others.

Action speaks louder than words.

二、 一般过去时:

1.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。

2.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, etc.

3.基本结构:be动词;行为动词

4.否定形式:was/were+not;在行为动词前加didn't,同时还原行为动词。

5.一般疑问句:was或were放于句首;用助动词do的过去式did 提问,同时还原行为动词。

6.例句:She often came to help us in those days.

I didn't know you
