Question

    An invention to tackle canal plastics pollution was one of the highlights of the recent Amsterdam International Water Week.

The instrument, named"the great Bubble barrier" is a bubble screen that will remove plastic trash from the canals and therefore prevent it from flowing through to the river IJ and the North Sea.

“This is a very important step in reducing the amount of plastic in the oceans,”co-inventor Philip Ehrhorn said “It is a lot easier to stop it at an earlier stage instead of in the ocean.”

The tool works as follows. By pumping air through a tube with holes in it, which is located on the bottom of a waterway, a bubble barrier appears. This creates an upward thrust, which brings waste to the surface of the water.

By placing it diagonally in the waterway, the barrier uses the natural current to guide the plastic to the catchment system at the riverside. Both ships and fish can pass through the Bubble Barrier, but plastic will be stopped.

The invention's origins go back around four years, when Dutch students Saskia Studer, Anne Marieke Eveleens and Francis Zoet looked at the bubbles of a beer glass in a bar and thought they should do something similar. Ehrhorn, a German student, had the same idea. After he found out about the plans of the three Dutch women, they decided to join forces in Amsterdam.

“It is the first step of many”, Ehrhorn continued on the project. “First, the different rivers and canals in the Netherlands-cities, industrial areas, ports. In the following years ,we will go to the rest of Europe, Asia and elsewhere.”

“We have learned to live with water and have built a thriving society.”Nijhof said.

1.What's a bubble barrier?

A.A dam made of concrete. B.An invention to trap plastic.

D.We can do nothing with sea waste.

3.Which paragraphs describe the barrier's working principle?

A.Paragraph 1&2. B.Paragraph 2&3.

C.Paragraph 3&4. D.Paragraph 4&5.

4.Which might be the best title of Paragraph 2&3 of the passage?

A.Plastic becomes easier to remove.

B.An action to remove the plastic.

C.An instrument will be invented.

D.A new invention to fight plastic pollution.

【解析】

本文是一篇说明文，介绍了一项能够对抗塑料污染的新发明——气泡屏障。

1.细节理解题。根据第二段“The instrument, named"the great Bubble barrier" is a bubble screen that will remove plastic trash from the canals and therefore prevent it from flowing through to the river IJ and the North Sea.”可知，这台被称为“大气泡屏障”的仪器是一个气泡筛，它可以清除运河中的塑料垃圾，从而防止塑料垃圾流入伊吉河和北海，再结合第四、五段介绍的工作原理可知，气泡屏障是一种能够收集塑料的发明，故B项正确。

2.细节理解题。根据第三段中的“This is a very important step in reducing the amount of plastic in the oceans,”co-inventor Philip Ehrhorn said可知，“这是减少海洋中塑料含量的一个非常重要的步骤”，菲利普·埃霍恩说，由此可知，他认为气泡屏障在某种程度上是有效的，故A项正确。

3.推理判断题。根据第四、五段内容，特别是第四段中的“The tool works as follows.”可知，这两段讲述了气泡屏障的工作原理，故D项正确。

4.主旨大意题。根据第二、三段内容，特别是根据第二段中的“The instrument, named"the great Bubble barrier" is a bubble screen that will remove plastic trash from the canals”及第三段中的““This is a very important step in reducing the amount of plastic in the oceans,”co-inventor Philip Ehrhorn said”可知，这台被命名为“大气泡屏障”的仪器是一个气泡筛，它可以清除运河中的塑料垃圾，共同发明人菲利普·埃霍恩评价说，“这是减少海洋中塑料含量的一个非常重要的步骤”，由此可知第二段和第三段主要讲的是一项能够对抗塑料污染的新发明，故D项正确。
