There are only two animals that have larger brains than man, the whale and the elephant. Yet, in proportion to his size, man's brain is larger. (19[C])Man's usually weighs about three pounds or a little more, and this is about one-fortieth of the weight of his whole body. The whale's body, on the other hand, is a thousand times heavier than its brain, while the elephant's body is about five hundred times as heavy.
But a man who has a large brain is not necessarily more intelligent than one whose brain is smaller. We know that geniuses have existed who have had very large brains, but there have been others whose brains were rather small. Idiots have been known to have very large brains.
(20[D])We do not understand precisely why some people are more intelligent than others. Whether our brains are relatively large or small is less important than that we try to do our very best.
This article is mainly about ______.
A．the weight of a whale's brain
B．the brains of geniuses
C．the size of a person's brain and his intelligence
D．the intelligence of the elephant
A．the brain of an elephant accounts for 1/50 of his total weight
B．many kinds of animals have brains larger than men have
C．man's brain seldom weighs much over three pounds
D．in proportion to his total weight, man's brain is the largest of animal brains

Country, sometimes called country-western, comes from two. kinds of music. (18[D])One is the traditional music of the people in the Appalachian Mountains in the eastern United States. The singers usually play guitars, and in the 1920s they started using electric guitars.
(19[A])At first city people said country music was low class. It was popular mostly in the South. (20[D])But during World War Ⅱ, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps in the South. They learned to like country music. Slowly it became popular all over the country.
Today country music is popular everywhere in the United States and Canada--in small towns and in New York City, among black and white, and among educated and uneducated people. About 1200 radio stations broadcast country music twenty-four hours a day. English stars sing it in British English, and people in other countries sing it in their languages.
