如:Nothing is permitted; everything is allowed. 一切都没明文划定可以做,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,而按划定那是不许可的。Visitors are not permitted to smoke in this area.观光者不得在此区域内吸烟。My dad won’t let me smoke in my bedroom. 我爸爸不让我在卧室内吸烟。
另外,★当用it作主语时,只有permit可用于被动结构。如:It is not permitted to smoke on this plane. (此时不能用allow)。
