An Analysis of Mr.Know All——Do not Judge a Book by its Cover

More often than not,people are inclined to think they have known a certain person enough by his or her everyday appearance,manners,speech and behaviors and therefore tend to draw their conclusions on what this person is like in nature.Nonetheless,this could be misguiding and a misconception if we don’t see how he or she reacts at the turning point of matters that concern not just him or her,but also others.Time reveals a person’s heart,so does the adversity as illustrated in the short story--Mr.Know All which tries to convey a key message to its readers:don’t make your judgment about a book by its cover until you have read it through.

追认权法律溯及力探究(英文)

If a person(known as the agent) acts without authority,or exceeds his authority,his actions cannot normally bind the person(known as the principal) on whose behalf he purports to act.However,subsequently,ratification allows the principal to adopt and endorse the agent’s acts.A remarkable feature of ratification is that it is retroactive in effect thereby becoming operative from the moment of the agent’s contracting with the third party rather than the moment of the principal’s ratification.
