slow slowly 作副词用,当“慢慢地”讲时,有何区别?

slow, slowly
（1） slow和slowly作副词时意思基本相同,但slow通常只与go, run等少数动词搭配,其比较级是slower.例如: My watch goes slow. 我的表慢了.
（2） slowly可用于各种情况,其比较级是more slowly.例如: There was something wrong with the childs eyes. He did everything very slowly. 那个小孩的眼睛有毛病,他无论做什么事都是慢腾腾的. Would you please say that again more slowly? 请你更慢地重复一遍,好吗?
