[简答题]Good manners are the art of making those easy with whom we converse. Whoever makes the fewest persons uneasy is the best bred in the company.
As the best law is founded upon reason, so are the best manners. And as some lawyers have introduced unreasonable things into common law, so likewise many teachers have introduced absurd things into common good manners.
One principal point of this art is to suit our behaviour to the three several degrees of men; our superiors, our equals, and those below us. For instance, to press either of the two former to eat or drink is a breach of manners; but a farmer or a tradesman must be thus treated, or else it will be difficult to persuade them that they are welcome. Pride, iii nature, and want of sense, are the three great sources of iii manners; without some one of these defects, no man will behave himself iii for want of experience; or of what, in the language of fools, is called knowing the world. I defy any one to assign an incident

[单项选择]Chess(国际象棋) must be one of the oldest games in the world. An Arab traveler in India in the year 900 wrote that it was played "long, long ago". Chess was probably invented in India. And it has been played everywhere from Japan to Europe since 1400. The name "chess" is interesting. When one player is attacking the other’s king, he says, in English, "check". When the king has been caught and cannot move anywhere, he says "check mate". These words come from Persian. "Shah mat" means "the king is dead". That is when the game is over, and one player has won.
Such an old game changes very slowly. The rules have not always been the same as they are now. For example, at one time the queen could only move one square at a time. Now she is the strongest piece on the board. It would be interesting to know why this has happened!
Chess takes time and thought, but it is a game for all kinds of people. You don’t have to be a master chess player in order to enjoy it. It is not always played by
A. the queen is the strongest piece on the board
B. the king had to be attacked all the time
C. the queen could move more than one square at a time
D. the king could not move anywhere
