都能表示 吃 的意思,但還是有區(qū)別的,eat是只能是吃的意思,用法比如：eat sth,而have還有其他的意思
have to do sth 不得不作某事
have sb done sth 讓某人作某事
have +名詞：擁有某物,某物有的特征,接受、收到,進行,吃飯,等等
have back拿回
have had it 受夠了
have it coming收到應(yīng)得的報應(yīng)
have it that說、主張
have off脫下,切斷
have on 佩帶
have something to do with與……有關(guān)
have got 擁有
這些是比較常用的詞組,對于HAVE來說,用法實在太多,一下子是歸不全的,have是一個很廣義的詞
