be beneficial to后加什么

be beneficial to后加名词或动词原形do，中文意思是“对某事或做某事有益”

It can be beneficial to share your feelings with someone you trust.

It may be beneficial to add a test that covers this code explicitly.

Advertising can be beneficial to the customers if it is true to its claims.

beneficial是有益的，有好处的。

这种词组用法不能死记硬背，要从语法上考虑。

to之后的单词是动词时是不定式，多作修饰成分，如something

to

eat等

to本身是介词，后应接名词性的词。表示“对”、“向”等，如I

say

something

to

you

move

to

the

east等。本题中to即为介词。

因此根据语境，尤其是之前出现的结构，看一看to后面需要接的词能否作这个结构的承受者。如look

forward

to等
