英语中有句谚语:You may take a horse to the river,but you can not make him drink.意思是说你可以把马带到河边,但你无法迫使其饮水。这个道理显而易见:事物内在的矛盾性是事物发展的源泉,它决定事物发展的性质和方向,因而是事物发展的根本原因,而外因是变化的条件,内因是变化的根据,外因通过内因起作用。在日常英语教学中,也渗透着这个道理。 You may take a horse to the river, but you can not make him drink. This means you can take the horse to the river, but you can not force it to drink water. This principle is obvious: the intrinsic contradiction of things is the source of the development of things, which determines the nature and direction of the development of things, which is the fundamental reason for the development of things, and external factors are conditions for change, the internal causes of change, external factors through internal factors . In everyday English teaching, also permeate this truth.
