[Q]: Article: John Coltrane was born in North Carolina in 1926 and raised in the small farm town of High Point. As a young boy, he spent a great deal of time listening to the music of the black Southern church. Coltrane's father sewed clothes and could also play several musical instruments for his own enjoyment. The young Coltrane grew up in such a musical environment. And he discovered jazz by listening to the recordings of such jazz greats as Count Basie and Lester Young. When John was thirteen, he asked his mother to buy him a saxophone. People realized almost immediately that the young man could play the instrument very well. John learned by listening to the recordings of the great jazz saxophone players, Johnny Hodges and Charlie Parker. In 1943 John and his family moved to Philadelphia, Pennsylvania. He studied music for a short time at the Granoff Studios and at the Ornstein School of Music. He served for a year in a Navy band in Hawaii. When he returned, he began playing the saxophone in several small bands. In 1948, Coltrane joined trumpet player Dizzy Gillespie's band. Seven years later, Coltrane joined the jazz group of another trumpet player, Miles Davis.Then he began experimenting with new ways to write and perform jazz music, and explored many new ways of playing the saxophone.Some people did not like this new sound, while others said it was an expression of modern soul and represented an important change. By 1965, Coltrane became one of the most famous jazz musicians in the world. He was famous in Europe and Japan, as well as in the United States. He was always trying to produce a sound that no one had produced before. Some of the sounds he made were beautiful. Others were like loud screams. Miles Davis said Coltrane was the loudest, fastest saxophone player that ever rived. Many people could not understand his music. But they listened anyway. Coltrane never made his music simpler to become more popular. He continued to perform and record even as he suffered from liver cancer. He died in 1967 at the age of forty in Long Island, New York.

[Q]: Article: I find some of the ways in which Chinese parents show love for their children rather surprising. Obviously there are some pretty big differences between our behaviors and theirs in this respect. Most Chinese children seem to get whatever they want, from ice creams, sweets and toys to endless attention from the adults around them. Is this a sort of spoiling or love? I wonder. Most westerners would think it is a sort of spoiling rather than love. We think love means educating your children and bringing them up to lead an independent life. That includes learning to accept the fact that he can't get everything he wants. As an adult, he will not always get the quite expensive car he hunts for; she will not always manage to acquire the beautiful dress she longs for. So we try to teach our children early to cope with the disappointment of not getting what they want. I find too much such kind of love for the children can actually spoil them. To my surprise, it seems that the life of a Chinese child is rather hard. Without doubt, the child is the very center of a whole circle of adults, but on the other hand he or she is also expected to start studying according to adults' wishes. Many children of my son's age take piano lessons, painting classes and even English lessons. It looks as if Chinese adults think that just playing without learning anything is a waste of time. So in this respect our children appear spoiled, just because they are allowed to play. But without this sort of play how can western children develop such free and rich imaginations? In fact the connection between this imagination and the creativity is so important in the children's future life.
Question: In which way do most Chinese children seem to be spoiled?
Options: (A) They can be supported by their parents. (B) They can play whenever they want. (C) They need not behave themselves. (D) Their demands can always be satisfied.
[A]: D

[Q]: Article: The best example of something is often called the "gold standard." It sets the standard against which other things are measured. In economics, the term describes how major trading nations once used gold to set currency values and exchange rates. Many nations continued to use the gold standard until the last century. In the United States, people could exchange paper money for gold from the eighteen seventies until nineteen thirty-three. Then-President Richard Nixon finally disconnected the dollar from the value of gold in nineteen seventy-one. From time to time, some politicians call for a return to the gold standard. In 1978, the International Monetary Fund ended an official gold price. The IMF also ended the required use of gold in _ with its member countries. Since that time, gold prices have grown and continued to be high. But people keep buying. Some people are "gold bugs." These are investors who say people should buy gold to protect against inflation . People have valued gold for thousands of years. The soft, dense metal polishes to a bright yellow shine and resists most chemical reactions. It makes a good material for money, political power -- and, more recently, electrical power. If you own a device like a mobile phone or a computer, you might own a little gold in the wiring. The gold standard was the subject of one of the best-known speeches in American political history. William Bryan wanted the country to use both gold and silver as money. The idea was to devalue the dollar and make it easier for farmers to pay their debts. So he delivered a speech, which made him famous. He was a presidential candidate three times. But he never won.
