Archimedes is most well-known for one specific idea that he came up with. "Archimede's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.
It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.
A good title for the selection is ______.
A．Archimedes
B．Archimedes' Principle
C．A gold and silver crown
D．The king of Syracuse

"Equal pay for equal work" is a phrase used by the American women who feel that they are unfairly treated by society. They say it is not right for women to be paid less than men for the same work.
Some people say men have more duties than women. A married man is thought to earn money to support his family and to make the important decision, so it is right for them to be paid more.
Some are even against married women working at all. When wives go out to work, they say, the home and children are given no attention to. (80) If women are encouraged by equal pay to take full-time jobs, they will be unable to do the thing.s they are best at doing: makinga nice home and bringing up children.
Women who disagree say they want to escape from the limited place which society wishes them to fill and to have freedom to choose between work and home life, or a mixture of the two.

A.pay men less than women
B.give women harder work
C.pay men and women the same amount of money for the same work
D.pay people more who do harder work
People who hold the opposite opinion(mainly men)have an answer to this. They say that men have more responsibility than women; a married man is expected to earn money to support his family and to make the important decision, and therefore it is right for men to be paid more. There are some people who hold even stronger opinion than this and are against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full time job, they will be unable to do the things. Women are best at making a comfortable home and bringing up children. They will have to give up their present position in society.
This is exactly what they want to give up, the women who disagree say. They want to escape from the limited place which society expects them to fill, and to have freedom to choose between a job and home life, or mixture of the two. Women have the right of equal pay and equal opportunities.
These women have expressed their opinions forcefully by using the famous saying, "All men are created equal. " They point out that the meaning of this sentence is "all human beings are created equal."

A．women's work shouldn't be harder than men's
