Passage Three
The water we drink and use is running short in the world. 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.

Passage Four
Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist’s failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.
