一般现在时口诀:
一般现在时,动词一般用原形。
表述事实讲真理,习惯动作常发生。
动词词尾加-s(es),只表单数三人称。
若变一般疑问句,得看句型是哪种。
系表结构和there be,be放句首可完成;
若遇实义动词句,do或does莫忘用。
一、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
I always get up at seven o'clock.
我早上总是7点钟起床。
He usually visits her grandparents>他通常在周末去看望他的祖父母。
We sometimes eat outside.
我们有时在外面吃饭。
You always blink when you tell a lie.
你说谎的时候总是眨眼睛。
二、基本结构
动词原形(如主语为第三人称单数,动词上要改为第三人称单数形式)
We always have seven classes every day.
我们每天上七节课。
It seldom snows here.
这很少下雪
He is always ready to help others.
他随时准备帮助其他人。
Action speaks louder than words.
行动胜于空谈。
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dont,如主语为第三人称单数,则用doesnt, 同时还原行为动词
He is always ready to help others.
变成否定句:He isn't always ready to help others.
We always have seven classes every day.
变成否定句:We don't always have seven classes every day.
He usually visits his grandparents>变成否定句:
He doesn't usually visit his grandparents>
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。
We always have seven classes every day.
变成一般疑问句:
Do you always have seven classes every day?
Action speaks louder than words.
变成一般疑问句:
Does action speak louder than words?
He is good at expressing himself.
变成一般疑问句:
Is he good at expressing himself?

五、词形变化

可数名词单数:a horse, this book, the moon, the earth
不可数名词:water, paper, time, money

5.have—has be –is
