有没有be benefit to sb 这个词组

1、用作名词.意思是：利益；好处
It is said Yogo is of great benefit to human health.
据说瑜咖功对人体健康有极大好处.

2、用作动词.（常与from,by连用）获益；得益于
The plants benefited from the rain.

固定搭配：
for the benefit of为了...的好处
benefit by [from] 受益于
benefit sb (sth) 对某人或某物有益,使某人或某物受益
be of benefit 有益处
have the benefit of 得益于,占……的光
你讲的那个种搭配方式貌似不行!

我在美国读了3年大学，我觉得应该是be beneficial to someone而不是be benefit to somebody. 比如, that rain is (actually) beneficial for students, as they will have a proper reason for absense.
当然，be benefit to sb也不是不行，但是听起来有点奇怪。 最好的用法还是，还是这个例句，that rain is a benefit for students, as they will have a proper reason for absense.
benefit在美国主要用于名词

(1)beofbenefitto:of+名词=（相应词根的）形容词，即ofbenefit=beneficial,beofbenefitto(对……是有利的/获益的)后通常跟sb.如：Asweallknow,itisofbenefitforstudentstostudyhard.(2)betoone'sbenefitto:对于……的（双重）利益而言.to之后应跟sth./dosth.如：Itistostudents'benefittostudyhard.
