approach to 后面一定是加动名词吗

当名词需要加to,如
make an approach to sb / a place
approach to sth 还有.的方法的意思
当动词用
approach sb / a place

1.As students,we should have the devotion to studies.
2.I havent got any answers to the questions yet.
3.The lady recongnized the thief when he tried to approach to her.
4.Polluting the environment will cause damage to our human beings.

1.approach做动词时,及物不及物均可.
所以如果是动词用法,则单用approach视为及物动词,直接即宾语均可；
用approach to则把approach视为不及物动词,后面加介宾短语to.
此时两者没有什么区别,后面都加宾语,只能说approach to...更强调一种方向或趋势.
2.approach做名词时,其后常加to...作为后置定语.
如：All the approaches to the village have been blocked.
通往这个山村的所有通道都被堵住了.
