Question

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big. All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags，bottles and containers—plastic products of all kinds.www.zxxk.com

The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert，with light winds and slow moving water currents. The water moves so slowly that garbage from all over the world collects there.

In recent years，there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste，resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full，lessening their desire to eat or drink.

The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste，and from eating fish that swallowed waste. Divers can also get trapped in the plastic.www.zxxk.com

Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier，another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.

In August，2009，a team from the University of California，San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.

【解析】

试题分析：文章讲述了太平洋垃圾带的有关情况。太平洋垃圾带位于美国加利福尼亚以西1600公里的地方，面积有两个得克萨斯州大小，都是由各种塑料产品堆积成的。这种垃圾不仅影响了海洋生物的健康， 也对人类健康产生了重大影响。

1.D推理判断题。文章第一段通过比较得克萨斯的面积和太平洋垃圾带的面积Imagine a mass of floating waste is two times the size of the state of Texas. …..imagine anything twice as big.，提出要讲述的中心，所以D为正确选项。

2.A细节理解题。根据文章第一段最后一句话The waste includes bags，bottles and containers—plastic products of all kinds.可知太平洋垃圾带多数是垃圾堆积起来的，故答案选A。

3.B根据文章倒数第二段There is an increased threat of infection of disease from polluted waste，and from eating fish that swallowed waste.可知人们食用吞食了塑料垃圾的鱼会感染某些疾病，因此食物链受到了影响，所以人们对此非常关注，答案选B。
