Background music may seem harmless, but it can have a powerful effect on those who hear it. Recorded background music first found its way into factories, shops and restaurants in the USA. Very soon it spread to other parts of the world. Now it is becoming difficult to go shopping or eat a meal without listening to background music.
To begin with, background music was intended simply to create a soothing (舒适的) atmosphere. Recently, however, it's becoming a big business. An American marketing expert has shown that music can boost(提升) sales or increase factory production by as much as a third.
But it has to be the light music. Lively music has no effect at all on sales. Slow music can increase receipts(收入) by 34%. This is probably because shoppers slow down and have more opportunity to spot items they would like to buy. Yet, slow music isn't always the answer. The expert found that in restaurants slow music meant customers took longer to eat their meals, which reduced overall sales. So restaurant owners might be well advised to play faster music to keep the customers moving-unless, of course, the resulting indigestion(消化不良) leads to complaints.Background music was first used ________.
| A．in the cinemas and theatres in the USA |
| B．in the offices and hospitals in the USA |
| C．in the schools and churches in the USA |
| D．in the factories, shops and restaurants in the USA |

The Cuban iguana(大蜥蜴) is a species of lizard（蜥蜴） of the iguana family． It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards． This species with red eyes and a thick tail is one of the largest lizards in the Caribbean．
The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses．However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident．
The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico. It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs. Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）.
In general the species is in decline, more quickly on the mainland than on the outlying islands． One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests． Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养） and other conservation programs．The underlined word "herbivorous" （Paragraph 2） probably means ．
| A．dangerous | B．gentle |
| C．flesh-eating | D．plant-eating |

When she moved the covering cloth to look upon his tiny face, she was shocked. The doctor turned quickly and looked out the tall hospital window. The baby had been born without ears.
Time proved that the baby’s hearing was perfect. When he rushed home from school one day and threw himself into his mother’s arms, she sighed, knowing that his life was to be full of heart- breaks for his imperfect appearance.
He grew up, handsome for his misfortune and popular with his fellow students. He might have been class monitor，but for that. He developed a gift, a talent for literature and music.
Two years went by. One day, his father said to the son, “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret.” The operation was a brilliant success, and a new person turned up. His talents blossomed into genius, and his school and college became a series of success. Later he married and entered the diplomatic service.
One day ,he urged his father, “Who gave so much for me？I must know! I could never do enough for him.”
“I do not believe you could, ” said the father, “but the agreement was that you are not to know... not yet.”

“Mother said she was glad she never let her hair be cut, ” he whispered gently, “and nobody ever thought Mother less beautiful, did they？”
