阅读理解 A flock of wild mandarin ducks(鸳鸯) are the biggest draw in the West Lake scenic area in Hangzhou, capital of East China's Zhejiang province, with tourists flocking from around the country to see them. However, some of the tourists have been feeding the ducks, even pulling them by the neck to force-feed them. On Monday, a video claiming that some of the ducks had died from over-feeding went viral on social networking sites. Although there are prominent signboards warning people against feeding them, tourists just cannot hold back. Some even believe the ducks are underfed and they are doing them a favor, little realizing that their action can be detrimental to the birds' health. Human food does not always go down well with ducks, particularly potato chips, as the oily snack can damage the health of mandarin ducks. However, tourists can frequently be seen feeding the ducks food that the birds cannot digest. Besides, feeding the ducks could stop them from competing in the wild to find their food. If they become dependent on food provided by humans, they will lose their survival skills. Also, by giving food to them, the tourists are polluting the environment. Especially, food thrown into the water could harm the ecosystem there. However, the tourists know little about the harm they cause to the environment and there is a need to create awareness about it. Meanwhile, the number of mandarin ducks at West Lake has dropped from 336 last year to 260 this year. Maybe the declining numbers will wake the tourists up to this reality. （1） What is the main reason for the ducks' death in the West Lake according to the passage? A .

D . beneficial. （3） What is the main idea of paragraph 3? A . Human food is not suitable for ducks to digest. B . Food thrown into the water does harm to the ecosystem. C . Tourists' feeding ducks may have a bad effect on ducks and the environment. D . Ducks may lose their survival skills if receiving food from people all the time. （4） What can we infer from the last paragraph about mandarin ducks in the West Lake? A . More mandarin ducks are seen in the West Lake this year than before. B . People have already known the damage they did to the mandarin ducks. C . More mandarin ducks are likely to be introduced to the West Lake in the future. D . It's high time that people should be aware of the harm to ducks caused by overfeeding. 答案： C A C D
