现在进行时和一般现在时
例如
He is playing basketball now.现在进行时
Im free now.一般现在时
1.now表明句子的时态应该是现在时态,包括现在进行时,一般现在时或现在完成时.
如
He is playing basketball now.现在进行时
I\'m free now.一般现在时
I\'ve finished my homework now,so I can go out with you.现在完成时
2.不过,有时候用其他时态也是可以的,如一般将来时.
如Now I\'ll intrdouce myself to you all.一般将来时
