permit与allow用法区别是什么?

permit较为正式，allow没有permit语气更强硬。比如：The nurse allow him to stay there,but it is not permited.另外allow可以接介词而permit不可以，如：She allow me in.在第二人称作主语表示请求的时候多用permit，如：Will you permit me to stay here.

allow 的一些常用搭配：
allow sb. to do sth
allow doing
allow sth.(for sb./sth)
eg.How much time would you allow for the trip?
allow for sb./sth考虑到，估计到
eg.All these factors must be allowed for.所有这些因素都必须估计进去
permit的一些常用搭配：
permit sb.to do sth.
permit doing sth.
permit 还可以作为名词，意为“许可证”

allow与permit的用法区别的用法区别
1.两者均可表示“允许”,其区别是permit 通常指上级、规则或法令等表示的准许,其语气较重；而 allow 通常指消极地不加反对,有时含有听任或默许之意,语气较轻.如：Nothing is permitted; everything is allowed.一切都没明文规定可以做,但一切做了也无妨.The nurse allowed him to remain there,though it was not permitted.护士让他留在那儿,而按规定那是不许可的.
2.从用法上看.两者后接动词作宾语时,均要用动名词形式,而不能用不定式.如：We don’t allow [permit] swimming in the pool.我们不许在池子里游泳.但是若其后接有名词或代词,那么其后须接不定式.如：We don’t allow [permit] children to swim in the pool.我们不许孩子们在池子里游泳.注意这类结构的被动式之后可用不定式(此时的不定式不是宾语,而是主语补语).如：正：We do not allow [permit] people to smoke here.正：People are not allowed [permitted] to smoke here.误：People are not allowed [permitted] smoking here.
