be fair with和be fair to兩個都是有公平對待的意思,
不過be fair with后面【一般】都是跟著each other或者是one another,意思為相互之間的公平對待.
Exp：It is important that we should be fair with one another.
相互之間應(yīng)該公平對待是很重要的.
而be fair to 后面一般是跟sb,意思也為公平對待.【P.S：be fair to sb和 be fair on sb意思一樣】
Exp：He is fair to his employees.
他對他的員工都很公平.
【注意：】
be fair to后面若跟著動詞,一般來說它意為“恰當(dāng)、合理”.
Exp：It is fair to say that they are pleased with the latest offer.
恰當(dāng)?shù)恼f,他們喜歡這一次的建議.
希望以上答案能夠幫到您.
