be beneficial to後加什麼

be beneficial to後加名詞或動詞原形do，中文意思是“對某事或做某事有益”

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，有好處的。

這種片語用法不能死記硬背，要從語法上考慮。

to之後的單詞是動詞時是不定式，多作修飾成分，如something

to

eat等

to本身是介詞，後應接名詞性的詞。表示“對”、“向”等，如I

say

something

to

you

move

to

the

east等。本題中to即為介詞。

因此根據語境，尤其是之前出現的結構，看一看to後面需要接的詞能否作這個結構的承受者。如look

forward

to等
