Football
Football is, I suppose, the most popular game in England: one has only to go to one of the important matches to see this. Rich and poor, young and old, one can see them all there, shouting and cheering for one side or the other.
One of the most surprising things about football in England to a stranger is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He has photographs of them and knows the results of a large number of matches. He will tell you, with a great air of authority, who he expects will win such and such a match, and his opinion is usually as valuable as that of men three or four times his age.
Most schools in England take football seriously--much more seriously than nearly all European schools, where lessons are all-important (至关重要的), and games are left for private arrangements. In England, it is believed that education is not only a matter of filling a boy's mind with facts in a classroom; education also means character training. One of the best ways of training character is by means of games, especially team games, where the boy has to learn to work with others for his team, instead of working selfishly(自私的) for himself alone. The school therefore arranges games and matches for its pupils. Football is a good team game, it is good exercise for the body, it needs skill and a quick brain, it is popular and it is cheap. As a result, it is the school's favorite game in the winter.
In England football is a game enjoyed ______.
A. only by young people
B. only by rich people
C. only by boys
D. by people of all ages and classes
Good Music
Music which is original is individual and personal. That is to say, it can be identified as belonging to a particular composer. It has particular qualities, or a style, which are not copied from another. If you can recognize the style. of a composer, you will probably be able to tell that a certain composition belongs to him or her even though you have never heard it before.
A basket-maker has the skill of weaving and interweaving his materials to create colorful patterns, and an expert carpenter(木匠) has the skill of joining together different shapes and sizes of wood to make a beautiful piece of furniture. These skills may be referred to as "workmanship" (技艺). Similarly, in music a composer organizes his melodies(旋律) and rhythms and combines sounds to create harmony. A composer may be capable of thinking up very good, original tunes, yet if tunes are poorly organized, that is, if the workmanship is poor, the final result will not be up to standard.
Good music expresses feelings in a way that is suitable to those feelings. These may be joy, sorrow, fear, love, anger, or whatever. Bad music, on the other hand, may confuse unrelated feelings, it may not express any not express any important feeling at all, or it may exaggerate some feelings and make them vulgar, that is, cheap and ugly.
Good music will stand the test of time. It will not go out of fashion but will continue to be enjoyed and respected long after it is first introduced. It will gain a king of permanent status while bad music will disappear and be forgotten quickly. In pop music, where the general rule seems to be "the newer the better", the test of time is the hardest test of all To pass.
A piece of original music ______.
A. has a personal style

C. is one whose style. you cannot recognize
