she always makes a smile on her face.和she always makes smiles on her face.区别,总干某事都要用复数
问题描述：
she always makes a smile on her face.和she always makes smiles on her face.区别,总干某事都要用复数
答
没有什么区别.
句意都是：她脸上总是带着笑容.
1.makes是动词的单三形式,因为句子主语She是第三人称单数,且句子为一般现在时,所以谓语动词要用单数形式.
2.make a smile 和 make smiles 其实是一个意思.
楼主理解为“总是做某事”,所以“不是一件事情”,所以用smiles更恰当吧?
但是每次做时,当时不也是“一件事情”吗?所以用a smile也没有任何问题.
3.再如：
He always play a joke on us.
He always plays jokes on us.
意思都是：他总是开我们的玩笑.
