单选题{{B}}Passage 22{{/B}} Movies are the most popular form of entertainment for millions of Americans. They go to the movies to escape their normal everyday existence and to experience a life more exciting than their own. They may choose to see a particular film because they like the actors or because they have heard the film has a good story. But the main reason why people go to the movies is to escape. Sitting in a dark theater, watching the images on the screen, they enter another world that is real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to be more romantic (浪漫的) and beautiful than in real life. The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world. American movies are popular because they tell stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can't. (22) {{U}}People have to cope with many problems and much trouble in real life, so they feel encouraged when they see the "good guys" win in the movies.{{/U}}

单选题Elephants don't forget—at least, female elephants don't. Elephant families are matriarchal. And the social knowledge gained by the oldest females is the key to a family group's survival, according to a study published in April by Karen McComb, a biologist at Sussex University in England. Elephants announce their presence by making a deep, long sound, a practice referred to as contact calling (联络呼叫). An unfamiliar call may mean that an elephant from outside the family group is nearby. A stranger can cause trouble, interrupting feeding or disturbing the young. So an elephant matriarch signals the family to gather around her; then they all lift their trunks in the air to smell the unfamiliar caller. False alarms can disturb the group and take time and energy away from feeding, so survival may depend in part on getting it right. Working with Cynthia Moss, who founded the Amboseli Elephant Research Project in Kenya 30 years ago, McComb tested the social knowledge of 21 Amboseli elephant families with matriarchs 27 to 67 years old. She played recordings of contact calls to each family and found that the oldest matriarchs were much better at picking out unfamiliar calls. In fact, a group with a matriarch in her fifties was several thousand times more likely to form into a group upon hearing an unfamiliar contact call than when hearing a familiar call. However, families with younger matriarchs "were less than twice as likely to gather together upon hearing an unfamiliar contact call as compared with a familiar call. And they gathered together a lot. Moreover, the social knowledge of older matriarchs translated into favourable results: Families with older matriarchs produced more baby elephants in each female-reproductive year. This finding shows how difficult it is to protect the oldest members of elephant families. As elephants age, they continue to grow larger, as do their much wanted tusks (象牙). So the older and wiser a matriarch is, the greater the chance she will be killed. About 800,000 elephants have been killed by people in the past 20 years.
