Passage Four How could we possibly think that keeping animals in cages in unnatural environments—mostly for entertainment purposes—is fair and respectful Zoo officials say they are concerned about animals. However, most zoos remain "collections" of interesting "things" rather than protective habitats. Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural zones. Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals’ natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species’ names, diets, and natural ranges. The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusual and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain. Furthermore, most animals in zoos are not endangered. Captive breeding of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven’t we seen enough competitions to name baby animals Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats. What does the author try to argue in the passage

Directions: There are 4 passages in this part. Each of the passages is followed by 5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D.Passage One SYDNEY: As they sat sharing sweets beside a swimming pool in 1999, Shane Gould and Jessicah Schipper were simply getting along well, chatting about sport, life and "anything else that came up." Yet in Sydney next month, they will meet again by the pool, and for a short time the friends will race against each other in the 50-meter butterfly (蝶泳) in the Australian championships at Homebush Bay. Gould, now a 47-year-old mother of four, has announced she will be making a return to elite competition (顶级赛事) to swim the one event, having set a qualifying time of 30.32 seconds in winning gold at last year’s United States Masters championships. Her comeback comes 32 years after she won three golds at the Munich Olympics. Schipper, now a 17-year-old from Brisbane with a bright future of going to Athens for her first Olympics, yesterday recalled her time with Gould five years ago. "I was at a national youth camp on the Gold Coast and Shane had come along to talk to us and watch us train," Schipper explained. "It seemed as if we had long been good friends. I don’t know why. We just started talking and it went from there." "She had a lot to share with all of us at that camp. She told us stories about what it was like at big meets like the Olympics and what it was like to be on an Australian team. It was really interesting. " Next time, things will be more serious. "I will still be swimming in the 50m butterfly at the nationals, so there is a chance that I could actually be competing against Shane Gould," said Schipper, who burst onto the scene at last year’s national championships with second places in the 100m and 200m butterfly. Gould won her three Olympic golds when she was ______.
Passage Two That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With the opening night only a week from now on, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me. As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers. Very few people were still out except a few sad-looking homeless people under blankets. About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk. Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found. Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, "Alisa Camacho" I thought I was dreaming. How could this man know my name the door opened, and out jumped a small red-haired man with an amused look in his eye. "Is this what you’re looking for" he asked, holding up a small square shape. It was nearly 3 am by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other. From the first paragraph, we learn that the writer was busy ______.
