漢語可說要求某人做某事，但英語習慣上不能說 demand sb to do sth, 遇此情況，可在 sb 前加介詞 of，也可改為 that 從句(注意用 虛擬語氣)。如：

　　■他要求我把一切都告訴他。

　　誤：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.

　　■他們要求每個成年人都應有選舉權。

　　誤：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.
