v.=原型/第三人称单身(do/does)
I tell you a secret.
He tells you a secret.
为什么用第三人称单词,为了和主语搭配。
1.一般情况下,直接在动词词尾+s
2.以s, x, sh, ch, o结尾的动词,在词尾+ es
3.以辅音字母+ y 结尾的动词,先把y变为i,再加es
4.不规则动词(特殊情况)
1 主语是he,she,it
2 可数名词的单数做主语
3 不可数名词做主语
小技巧:判断主语是不是三单,看主语可不可以用he,she,it替换
频率从高到低:always,usually,often,sometimes,never…
We have the English class every day.
He often gets up late.
I am a teacher.
We are happy together.
1 客观事实
The earth is round.

2 科学真理

3 名言金句
Practice makes perfect.
be: 加上not
实义动词:借助do/does + not
be:be 动词提前
实义动词:借助助动词,助动词do/does提前。
am/is/are + doing
1)一般 + ing
2)以不发音的e结尾的去e+ing
3)辅元辅(汉堡堡结构),双写辅音字母+ing。除了opening.
用法1: 表示现在正在进行的事情。(现在短时间的概念:此时此刻;现在短意义的长时间概念)
We are studying English now.(短时间的概念:此时此刻)
J.K. Rowling is writing another booke this year(长时间的概念现在)
用法2:表示将来确定要发生的事
I am comming to see you.(我确定要来看你)
We are arriving at…(确定要到某站)
The old man is dying.(不能现在正在死,而是确定将要死了)
1 否定
be + not + doing
He is listening.
He is not listening.
2 疑问
be 动词提前
Is he listening?
两种时态都是表示现在,但是一般现在习惯性的动作,现在进行表示此刻的动作。
