要看你的句子主语是什么了。如果主语是一件实际的事情，后面就用be
beneficial
to
doing
sth.
如：reading
a
lot
is
beneficial
to
(improving)
your
english.
但是如果主语是it
作为形式主语，那么通常后面用不定式作为真正的主语，即用be
beneficial
to
do
sth.
如：it
is
beneficial
to
read
a
lot.=to
read
a
lot
is
beneficial
(to
you).
以下类同。
有问题欢迎追问~~~

be beneficial to 后面接的动词形式要按句意的需求决定，
请看例句：
It is beneficial to eat fruits and vegetables （接动词不定式）
Exercise is beneficial to keeping healthy and strong （接动词ing 形式引导名词短语）
就你的例句，正确的表达方式是
Reading is beneficial to improving our English skills

be beneficial to一般都是接名词sb.或sth.要接动词的话只能ing形式的。

用动名词doing因为to为介词.
