     How words came into being is unknown. All we assume(推测)is that some early men invented

certain sounds, in one way or another, to express thoughts and feelings, actions and things, so that

they could talk with each other. Later they agreed upon certain signs, called letters, which could be

put together to show those sounds, and which could be written down. Those sounds, whether spoken

or written in letters, are called words.

     The power of words, then, lies in their associations - the things they bring up to our minds. Words

become filled with meaning for us by experience; and the longer we tire, the more certain words bring

back to us the happy and sad events of our past; and the more we read and learn, the more the number

of words that mean something to us increases.

     Great writers are those who not only have great thoughts but also express these thoughts in words

which have powerful effects on our minds and feelings. This clever use of words is what  we call literary

style(文体). Above all, the real poet is a master of words. He can express his  meaning in words which

sing like music, and which by their position and association can move men to tears, We should therefore

learn to choose our words carefully and use them correctly, or they will make our speech silly and

common.
