题目内容
【题目】 Engineers have launched a huge garbage collection device to gather plastics floating in the Pacific Ocean between California and Hawaii. The plastic makes up what is called the Great Pacific Garbage Patch. It is the world’s largest spread of garbage, twice the size of the state of Texas.
The Organization Ocean Cleanup created the collection device. The group’s founder is Boyan Slat, a 24-year-old inventor from the Netherlands. When Slat was 16, he went diving in Mediterranean Sea and saw more plastic bags than fish. Since then, he has made up his mind to clean up the oceans.
He told the Associated Press that researchers with his organization have found plastic from the 1960s and 1970s among the material in the Great Pacific Garbage Patch. It contains an estimated 1.8 trillion pieces of plastic in total. Most of them float on the surface of the water, or are within a few meters of the surface.
Last Saturday, a ship pulling the pipe-shaped floating barrier left San Francisco for the Garbage Patch. The barrier, called the floater, is 600 meters across. Attached to it is a screen (筛子) that hangs three meters down in the water. The screen is designed to collect the plastic as it moves through the water. Sea animals can safely swim under the barrier. The cleanup system also comes with lights powered by the sun, cameras, and other special devices. Slat said this enabled the system to communicate its position at all times.
Shipping containers will hold all the plastic gathered, including bottles and fishing equipment. Slat said the containers were expected to be back on land within a year. Then the plastic will be recycled. And they will also study how the system performs in severe ocean conditions, including huge waves.
【1】How did Boyan Slat react to that dive in the Mediterranean Sea?
A.He showed a great interest in diving.
B.He became worried about his safety.
C.He decided to remove the garbage in oceans.
D.He became curious about underwater creatures.
【2】What has the organization Ocean Cleanup found about the Great Pacific Garbage Patch?
A.Most of its plastic is half a century old.
B.It covers almost the size of the state of Texas.
C.Altogether there are about 1.8 billion pieces of plastic.
D.The majority of its plastic floats on or near the surface.
【3】Why was a screen attached to the ship?
A.To power lights in the ship.B.To protect sea animals near it.
C.To tell the position of the ship.D.To collect plastic along the way.
【4】What is the text mainly about?
A.Approaches to removing garbage in oceans.
B.The problem of garbage in the Pacific Ocean.
C.A young man who does well in classifying garbage.
D.A huge device made to clean garbage in oceans.
【答案】
【1】C
【2】D
【3】D
【4】D
【解析】
这是一篇说明文。本文主要讲述了年轻发明家Boyan Slat 16岁时在地中海潜水时发现塑料袋比鱼多,决心清理塑料并发明巨大的清理装置,且详细介绍了装置的功能。
【1】细节理解题。根据第二段中When Slat was 16, he went diving in Mediterranean Sea and saw more plastic bags than fish. Since then, he has made up his mind to clean up the oceans.可知16岁时,他去地中海潜水,看到的塑料袋比鱼还多。从那时起,他就下定决心要清理海洋。由此可知,Boyan Slat在地中海潜水时,他决定清除海洋中的垃圾。故选C。
【2】细节理解题。根据第三段最后一句Most of them float on the surface of the water, or are within a few meters of the surface.可知它们大多漂浮在水面上,或者离水面只有几米远。由此可知,海洋清理组织在大太平洋垃圾带时,发现了大部分塑料漂浮在表面或附近。故选D。
【3】细节理解题。根据第四段中The screen is designed to collect the plastic as it moves through the water.可知这个筛子是用来收集在水中流动的塑料的。由此可知,在船上安装筛子是为了沿途收集塑料。故选D。
【4】主旨大意题。根据第一段中Engineers have launched a huge garbage collection device to gather plastics floating in the Pacific Ocean between California and Hawaii.可知工程师们已经发射了一个巨大的垃圾收集装置来收集漂浮在加利福尼亚和夏威夷之间的太平洋上的塑料。结合本文用了大篇幅介绍了这个清理海洋垃圾的巨大装置,从它的发明家,它的由来,使用方法等方面介绍。由此可知,文章主要讲了清洁海洋垃圾的巨大装置。故选D。
