Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity; it can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge？ Smith has one principal rule for all teaching instructions. "Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children. "
When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfil them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.

A．it is one of the most difficult school courses

Archimedes is most well-known for one specific idea that he came up with. "Archimedes'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's Principle
C．A Gold and Silver Crown
D．The King of Syracuse

Archimedes is well-known for one specific (精确的) idea that he came up with. "Archime des' principle" tells us 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 moves. For example, if you put a piece of wood and a piece of metal of the same size in water, only the wood will float. Both the wood and metal move the same amount (量) of water, but the water moved by the wood weighs less than that of the water moved by the gold. 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 (皇冠) was pure gold or a mixture of gold and silver. The King, of course, did not want to 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 the one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the King.
