Question

    Feeding bread to the ducks is a fond pastime for many of us, reminding us of our happy childhood trips to the local park. But did you know that bread actually poses a danger to birds, as well as the environment? Eating it can cause our feathered friends to develop a condition called Angel Wing, which is when too much bread makes birds’ feathers grow too quickly. This additional weight puts a strain on their muscles, causing their wings to twist and drop open, and if not treated fast, they can lose the ability to fly.

“Angel Wing can be remedied if we reach birds before it has developed too severely,” says Caroline Simpson, a trustee of UK charity Swan Lifeline, which has rescued and treated more than 30,000 birds over the last 20 years. “Otherwise the consequence can be awful—such as amputations(截肢)of the wing.” Adult swans can also develop gut and heart disease, so it’s important we do our bit to prevent this by feeding wild birds with the right kind of food.

Bread can also cause harmful changes to the natural ecosystem. Rotting bread at the bottom of  rivers and lakes allows bacteria to breed, spreading disease and attracting rats and other vermin to our waterways. It can result in algal(藻类的)blooms and the presence of a mould(霉菌)called Aspergillus too, which has the potential to kill waterfowl(水禽)and other wildlife if it gets into their lungs.

But this doesn’t mean we have to stop fun trips to feed the ducks. Giving birds the right food-like frozen peas, sweetcorn and lettuce leaves-is good for both them and the environment. So, next time  you visit your local park, take a healthier alternative with you and do your bit to protect our precious wildlife.

3.D

【解析】

本文是一篇说明文，介绍了用面包喂水禽不仅会对水禽造成危害，而且还会给环境带来不利影响，所以我们要用正确的方法喂水禽。

1.词义猜测题。根据划线词后的“if we reach birds before it has developed too severely”可知，如果我们能在“天使之翼”这种病发展得不太严重的时候接触到鸟类，那么这种病造成的影响就可以得到补救，由此可知划线词词义为“纠正、补救”，故D项正确。

2.细节理解题。根据第一段中的“which is when too much bread makes birds’ feathers grow too quickly. This additional weight puts a strain on their muscles, causing their wings to twist and drop open, and if not treated fast, they can lose the ability to fly.”可知，吃太多的面包会使水禽的羽毛长得过快，这种额外的重量会使它们的肌肉发紧，导致翅膀扭曲并张着，如果不迅速治疗，它们可能会失去飞行的能力（水鸟会吃得过多，并有丧失身体机能的危险）；根据第三段中的“Rotting bread at the bottom of rivers and lakes allows bacteria to breed, spreading disease and attracting rats and other vermin to our waterways.”可知，在河底或湖底腐烂的面包会让细菌繁殖，传播疾病，并吸引老鼠和其他害虫到我们的水道；再根据第三段中的“It can result in algal(藻类的)blooms and the presence of a mould(霉菌)called Aspergillus too, which has the potential to kill waterfowl(水禽)and other wildlife if it gets into their lungs.”可知，腐烂的面包也会导致藻类的大量繁殖和一种叫做曲霉的霉菌的存在，如果它进入水禽和其他野生动物的肺部，可能会杀死它们（河底或湖底的生态平衡将被破坏），以上三点都是用面包喂水禽会带来的后果，而文中没有提到面包中的营养物质会让水质会变得丰富，故C项正确。

3.推理判断题。通读全文，特别是根据第一段中的“But did you know that bread actually poses a danger to birds, as well as the environment?”可知，用面包喂水禽不仅会对水禽造成危害，而且还会给环境带来不利影响，再结合第二段中的“so it’s important we do our bit to prevent this by feeding wild birds with the right kind of food.”可知，我们必须尽自己的努力，用正确的食物喂养野生鸟类，由此可知，本文的目的是呼吁大家用一种正确的方法喂水禽，故D项正确。
