We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.
The way to stop wasting our limited water is to ().
A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater

Passage Two
How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.
The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, 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 dull and silly.
Which of the following did men invent first?
A.Words.
B.Sounds.
C.Signs.
D.Letters.
