Passage 2How men first learnt to invent words is unknown, in other words, the origin of language is a mystery.All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feeling, action, and things, so that they could communicate with each other.And later, they agreed upon certain signs, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written, we call words.The power of words lies in their associations with the things they bring up before our minds. Words become filled with meaning for us by experience. The longer we live, the more certain words recall to us the glad and sad events of our past. 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 appeal powerfully to our minds and emotions. This charming use of words is what we call literary style.Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar. According to the passage, in expressing their thoughts, great writer are able to ________.

A、move our actions
B．speak powerfully
C．arouse our feelings
