allow permit这两个词的意义与用法相近permit这个词稍微正式一些,其意义为“允许”“准许”
其句型为：1、allow/permit sth 2、allow/permit sb to do sth 3、allow/permit doing sth
如：①This plant allows one hour for lunch.
这家工厂允许一个小时的吃饭时间.
②He would not permit the waste of a single grain.
他不允许浪费一粒粮食.
③They don't allow/permit people to smoke in the offices．
④We don't allow/permit smoking in the offices．
⑤Talking loudly is not allowed/permitted in the library.
但是allow可以与状语小品词连用,permit则不能
如：①She would it allow me in．
她不愿让我进去
②Mery isn't allowed out at night．
晚上不允许马丽出去.
以上两句中的“allow”不能用permit代替.
permission是permit的名词形式
