For thousands of years, people thought of glass as something beautiful to look at. Only recently have they come to think of it as something to look through. Stores display their goods in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary objects.
Until the Second World War, most of the glass used for optical instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. As a result, new kinds of glasses were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of these new glasses are very strong and can resist many kinds of shocks. Legend has it that a very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and silver, making his treasure worthless. Therefore, he had the glassmaker killed, and the secret was not discovered again for hundreds of years.
In the present century, safety glass was invented for use in modern cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter and injure people. Some glass of this type is strong enough to resist bullets.
Although in recent years plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component parts are inexpensive and can be found all over the world. [br] With the passage of time, glass _____.
选项
A、is regarded as transparent
B、is no longer seen as decoration
C、is used to make things look pleasant
D、is widely used to replace steel in making containers
答案
B
解析
本题考查倒装句的理解。从文章第2句的开头only recently可知第1句和第2句是对比关系:现在的情况与以前不一样了。因此B为正确选项。选项A是对原文第2句话的曲解,虽然这句话中说到的玻璃现在被视为something to look through,但是,这句话要强调的并不是到现在人们才发现玻璃是透明的,而是要强调玻璃可以被用作工具,透过它去看别的东西。选项C中的look pleasant和选项D在文中都没有提到。
