　　Where Has the Salt Come from?

　　Every now and then, we meet a fact about our earth that makes us feel strange and no answer for the fact has yet been found. Such a fact is the existence of salt in the oceans. How did it get there?

　　We simply do not know how the salt got into the ocean! We do know, of course, that salt is water-soluble, and so passes into the oceans with rainwater. The salt of the earth's surface is constantly being dissolved (溶解) and is passing into the ocean.

　　But we do not know whether this can explain the huge quantity of salt in oceans, if all the oceans were dried up, enough salt would be left to build a wall 180 miles high and a mile thick. Such a wall would reach once around the world at the Equator (赤道)!

　　The common salt that we all use is produced from seawater or the water of salt lakes, from salt springs (源泉) and from deposits of rock salt. The concentration (濃度) of salt in seawater ranges from about three per cent to three-and-one-half percent. The Dead Sea, which covers an area of about 340 square miles, contains about 11,600,000,000 tons of salt!

　　On the average, a gallon (加侖) of seawater contains about a quarter of a pound of salt. The beds of rock salt that are found in various parts of the world were all originally formed by the evaporation (蒸發(fā)) of seawater millions of years ago. It is believed that the thick rock-salt deposits were formed after about nine-tenth of the volume of seawater had been evaporated.

　　Most commercial salt is obtained from rock salt. The usual method is to drill wells (井) down to the salt beds. Pure "water is pumped down (抽進去) through a pipe. The water dissolves the salt and it is forced through another pipe up to the surface.

　　16 We have not fully understood how salt got into the ocean.

　　17 The author is sure that the dissolved salt from the earth's surface is the only source of the huge quantity of salt found in oceans.

　　Early Ideas about the Universe

　　1　Early man got his ideas about the universe by looking at the stars as you do. He observed carefully, and learned many things about the sun, the moon, and the stars.{來源：考{試大}

　　2　Suppose you were asked to collect evidence about the sun as early man did. You might go out morning after morning and see it come up in the east. Even on cloudy mornings, you would observe that the darkness goes away and the world becomes light. You might not see the sun but would be sure it is there, because you notice that the earth warms up. As you continued, the sun climbs higher in the sky each day during part of the year. It stays in the sky longer. The earth gets warmer. Things begin to grow. It is spring and then summer.

　　3　After a while the sun stays in the sky for shorter and shorter periods. Many plants begin to die. Leaves fall. Winter comes. Year after year this is repeated and you cannot tell exactly why it happens. But you realize that the sun seems to make the difference. Primitive (原始的) man felt that since the sun was so powerful it must be a god. It may seem silly to us now to worship (崇拜) a sun-god, but primitive man was right about the importance of the sun to life on earth.

　　4　You have been told that the world is round. But suppose no one had ever taught you that the world was like a huge ball. Would you have ever thought of it yourself? You cannot see the curve (曲線) of the earth at once. You would have no idea of how big it was. That's why early man believed that the earth was small and fiat. Such ideas appeared from the evidence they had.

　　5　If you watch the stars night after night, you will see them rise and set. As you look at the sky, it is not difficult to imagine that you are in the center of a vast collection of twinkling (閃爍) lights. Some early astronomers (天文學(xué)家) believed the sky was a crystal shell or series of crystal shells, one inside the other. They believed this because that is what the night sky looked like. For many centuries, men believed that the earth was the center of the universe and that the sun, the moon, and the stars circled around it.
