With the improvemwnt of our new product,we can guarantee full satisfaction to our customers.
这里的guarantee为什么不可以换成promise?

promise不存在promise sth to sb的用法,一般有:
promise to do sth承若做某事
promise sb sth 承诺某人某事
guarantee 确保,保证
guarantee sth to sb符合语法要求可是字典上写了promise sth (to sb),是不是不常用啊?用的少,也有这么用的。再有一点,promise也不满足题目意思,该句话是说“我们要确保客户满意”,“承诺顾客满意”也说不通啊!应该是承诺顾客怎么怎么样,用promise +that从句。
