现在进行时的否定句在be动词后加not,例如"I am not studying",也可以使用缩写形式,例如"I'm not studying"。疑问句则将be动词提前至主语之前,例如"Are you studying?",回答时需要将be动词和主语的顺序颠倒,例如"Yes, I am."或"No, I'm not."。
现在进行时的否定句
构成现在进行时的否定句需要在be动词后面加not。be动词有am、is、are三种,取决于主语的单复数和人称。比如:
- I am not studying.(我不在学习。)
- She is not eating.(她没有在吃东西。)
- They are not playing basketball.(他们没有在打篮球。)
同时,如果要使用缩写形式,可以将not和be动词缩写成n’t。比如:
- I’m not studying.(我不在学习。)
- She isn’t eating.(她没有在吃东西。)
- They aren’t playing basketball.(他们没有在打篮球。)
现在进行时的疑问句
构成现在进行时的疑问句需要将be动词提前至主语之前,并在句末加问号。比如:
- Are you studying?(你在学习吗?)
- Is she eating?(她在吃东西吗?)
- Are they playing basketball?(他们在打篮球吗?)
同时,当回答疑问句时,需要将be动词和主语的顺序颠倒。比如:

- A: Is she eating? B: Yes, she is. / No, she isn’t.
- A: Are they playing basketball? B: Yes, they are. / No, they aren’t.
