the professor is proving his theory to his students这句不能这样吗.the professor proves his theory to his students.用prove直接做谓语动词.
答
时态问题，
原句为正在进行时
the professor is proving his theory to his students
意为：教授正在向学生证明他的理论。
你改的是一般现在时
the professor proves his theory to his students every day.
教授每天都向学生证明他的理论。
答
这里两个句子主要区别在时态问题上.
the professor is proving his theory to his students.这一句是正在进行时
the professor proves his theory to his students.这一句是一般现在时态.
如果用prove直接做谓语动词,那样的话,表达的时态就不一样了.
