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. In the state of zoochosis, animals ______.
A. remain in cages
B. behave strangely
C. attack other animals
D. enjoy moving around

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. What Schipper said showed that she ______.
A. was no longer Gould’s friend
B. had learned a lot from Gould
C. was not interested in Gould’s stories
D. would not like to compete against Gould
某工程,建设单位和施工单位按《建设工程施工合同(示范文本)》签订了施工合同,在施工合同履行过程中发生以下事件: 事件1:工程开工前,总监理工程师主持召开了第一次工地会议。会上,总监理工程师宣布了建设单位对其的授权,并对召开工地例会提出了要求。会后,项目监理机构起草了会议纪要,由总监理工程师签字后分发给有关单位;总监理工程师主持编制了监理规划,报送建设单位。 事件2:施工过程中,由于施工单位遗失工程某部位设计图纸,施工人员凭经验施工,现场监理员发现时,该部位的施工已经完毕。监理员报告了总监理工程师,总监理工程师到现场后,指令施工单位暂停施工,并报告建设单位。建设单位要求设计单位对该部位结构进行核算。经设计单位核算,该部位结构能够满足安全和使用功能的要求:设计单位电话告知建设单位,可以不作处理。 事件3:由于事件2的发生,项目监理机构认为施工单位未按图施工,该部位工程不予计量;施工单位认为停工造成了工期拖延,向项目监理机构提出了工程延期申请。 事件4:主体结构施工时,由于发生不可抗力事件,造成施工现场用于工程的材料损坏,导致经济损失和工期拖延,施工单位按程序提出了工期和费用索赔。 事件5:施工单位为了确保安装质量,在施工组织设计原定检测计划的基础上,又委托一家检测单位加强安装过程的检测。安装工程结束时,施工单位要求项目监理机构支付其增加的检测费用,但被总监理工程师拒绝。【问题】1.指出事件1的不妥之处,写出正确做法。 2.指出事件2的不妥之处,写出正确做法。该部位结构是否可以验收为什么 3.事件3中项目监理机构对该部位工程不予计量是否正确说明理由。项目监理机构是否应该批准工程延期申请为什么 4.事件4中施工单位提出的工期和费用索赔是否成立为什么 5.事件5中总监理工程师的做法是否正确为什么
