need sb to do sth 需要某人做某事

要說的是 沒有need sb do sth

例子：i need you to finish your homework. （我讓你完成你的作業）

need 可以做情態動詞, 但用法不是 need sb do sth, 用法同其他情態動詞 即need do sth,

同時need 也可以做普通動詞,就有了 need sb to do sth. 這種用法

sb need to do sth

sth need doing sth

need to do (需要做……)表示主動語態,主語為人.

need doing(需要被做)表示被動語態[相當於need to be done],主語為物.

call for sb to do sth 要求某人做某事
