汉语可说要求某人做某事，但英语习惯上不能说 demand sb to do sth, 遇此情况，可在 sb 前加介词 of，也可改为 that 从句(注意用 虚拟语气)。如：
■他要求我把一切都告诉他。
误：He demanded me to tell him everything.
正：He demanded of us to tell him everything.
正：He demanded that I should tell him everything.
■他们要求每个成年人都应有选举权。
误：They demanded the right to vote to be given to every adult man.
正：They demanded for the right to vote to be given to every adult man.
正：They demanded that the right to vote be given to every adult man.
