一般现在时和现在进行时用法总结
Hi, my friends! 这个学期我们认识了两个时态朋友——一般现在时和现在进行时。你们知道吗？虽然这对朋友都表示动作发生在现在，但它们在具体使用时却是界限分明，水火不容！今天就让它们来“对抗”一下吧！
一、现在进行时态：表示现在正在进行或发生的动作。
1.构成
be动词 ( am / is / are ) + 动词的ing形式
2.肯定、否定和疑问式
（1）肯定式：I am studying.
You are studying.
He / She is studying.
We / You / They are studying.
（2）否定式：I’m not studying.
You aren’t studying.
He / She isn’t studying.
We / You / They aren’t studying.
（3）特殊疑问句及回答：
—What are you doing? 
—I’m studying.
—What is he / she doing? 
—He / She is studying.
—What are we / you / they doing? 
—We / You / They are studying.
二、一般现在时态：表示现阶段经常发生或习惯性的动作。
1．构成
（1）当主语是第三人称单数（如：she, he, it等）时，动词就用第三人称单数形式，一般情况下，动词的第三人称单数形式往往就是在动词末尾加上“s”。例如：
She often goes to the park on the weekend.
（2）如果主语不是第三人称单数，则动词只需用原形。例如：
We often go to the park on the weekend.
2．肯定、否定和疑问式
（1）肯定式：I / We / You / They play football on the weekend.
She / He often plays football on the weekend.
（2）否定式：I / We / You / They don’t often play football.
She / He doesn’t often play football on the weekend.
（3） 特殊疑问句及回答：
—When do you eat dinner?  
—I often eat dinner at 6:00 p.m.
—What does she often do on Sundays?
—She often plays the piano.
