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.

C.A canal to deal with waste. D.A container to hold beer.

2.According to Philip Ehrhorn, which of the following is true?

A.The barrier is effective in a way.

B.It's easy to deal with plastic.

C.This instrument can deal with all waste.

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.

Instead of cruising in on a hoverboard, I rode my bike to the office today. The bicycle was invented in the 19th century. Instead of taking a pill for breakfast, I had a bacon roll, cooked using gas. Science fiction has ________ to us.

Making predictions is tricky, especially about the future, as physicist Niels Bohr joked. In science fiction, you can’t escape that ________ though. Since its birth in the 19th century, writers have ________ imagined the things to come: devices that humankind will invent to make life easier. But in so many instances, those promises have not come to pass. The biggest ________ are in travel—jet packs, hoverboards and flying cars are yet to fill the skies. Air travel has become significantly cheaper and wide-reaching, but only using distinctly 20th-century technology: commercial aeroplanes are much the same as they were 50 years ago.

________ is what science fiction frequently delivers, but its arrival in the real world has been unpredicrable. Domestic robots with a degree of intelligence are yet to ________, though robotic vacuum cleaners are commercially available—even if they are fairly hopeless. Video calls have now arrived—sort of—but conferencing on Skype is still dissatisfying. In mobiles, video call technology is now available, so when your dad rings to update you on his vegetable patch, he’ll be able to ________ your look of boredom.

The truth is that we quickly ________ the astonishment of invention: our wonderment is soon replaced with the feeling of nothing new. We should try to stay in that period of ________. It is astonishing that the contents of every book ever written can be stored in a small box. Or that you can carry 10,000 albums on an object kept in your pocket. Or that almost all the information in the world can be accessed almost anywhere at any time. All these ________ are dependent on the emergence of the microchip and its place in computers. Yet sci-fi didn’t ________ the dominance of the computer in running our lives.

But the real area where ________ far outstrips（超越）predictions is medicine. Sure, fiction would describe humans as“disease-free”but without going into detail.“Disease-free”humans are still absent, but the progress made in ________ life is breathtaking. With relative ease, we can sequence anyone’s genome（基因组），giving a read-out of our entire genetic code. This means we can find out the underlying genetic cause of thousands of diseases in minutes.

Photosensitive implants now exist that can replace damaged cells in the retina（视网膜）and can, thus ________ sight to the blind. While the inventions of science fiction can show great ideas we’d like to happen, nothing ________ the inventiveness of people in the real world.

高二英语完形填空困难题查看答案及解析

There have been many great inventions that changed the way we live. The first great invention was one that is still very important today—the wheel. This made it easier to carry heavy things and to travel long distances. For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People did not have to explore much anymore. They began to work instead to make life better. In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today.

The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wear. The middle part of the 20th century brought new ways to help people get over disease. They worked very well. They made people healthier and let them live longer lives. By the 1960’s most people could expect to live to be at least 60. By this time most people had a very good life.

Of course new inventions continued to be made. But man now had a desire to explore again. The world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space. In 1969 man took his biggest step away from the earth. Americans first walked on the moon. This is certainly just a beginning, though.

New inventions will someday allow us to do things we have never yet dreamed of.

1.Why did the world start to change in the early 1800’s?

A.Because there were few inventions that had as much effect as the wheel for hundreds of years.

B.Because people began to work to make life better instead of exploring unknown world.

C.Because there was little unknown land left in the world.

D.Because people did not have to explore much anymore.

2.In Paragraph 2, the word “They” in the sentence “They worked very well” refers to ________.

A.helicopters, computers, jet planes, nylon B.new materials

C.new ways to help people get over disease D.people

3.Why did man have a desire to explore again?

A.Going into space is a dream for man to realize.

B.Man wanted to move to other stars.

C.Other countries wanted to follow Russia.

D.Other countries wanted to catch up with America.
