It is only a shiny, yellow metal, but it is one of the most valuable metals on earth. Since the beginning of time, men have looked for this extremely valuable item, gold.
Gold is soft and easy to form into different objects. If it gets wet, it does not rust like iron or other metals. Acids do not change it. One important reason that gold is so valuable is that it is scarce.
Due to its softness, gold must be combined with other metals to harden it and give it strength. By hardening gold, people can then make coins and jewelry with it. Metals commonly mixed with gold are nickel, platinum, and copper. Gold jewelry bears a number and the letter K. The K means karat(carat), which is a measure of the amount of pure gold in the jewelry. Pure gold is 24K. Therefore, a necklace which is 14K is fourteen parts gold and ten parts other metal.
Many countries utilize gold for certain coins, but this practice is not as common now as it once was. The United States, for instance, stopped making gold coins in 1933.
Which is NOT the reason why gold is highly valuable?
选项
A、It can be made into jewelry.
B、It is not easily found.
C、It is soft and shiny.
D、It does not rust when wet.
答案
C
解析
事实细节题。题干大意为:下列哪一项不是黄金贵重的原因?A.黄金可做成珠宝;B.黄金不易找到;C.黄金质地软,闪闪发光;D.黄金受潮不会生锈。比较四个选项可知A,B,D项都是在说黄金的可贵之处,而C项的前半部分绝非黄金的优点,因为文章明确提到黄金需和其他金属融合以提高其强度,才方便制成物品。由此可知,C不是黄金贵重的原因。
