高中英语寒假每日一练答案：20210205

Fired bricks are a universal building material, produced by thousand-year-old technology, which throughout history has seldom served any other purpose. But researchers at Washington University in St. Louis have found a new use for bricks:as energy storage units. A team of engineers and chemists have found a way to transform an ordinary house brick into a battery(电池)—allowing it to conduct (传导)and store electricity.

The researchers connect an LED light bulb(灯泡)to the bricks. They are powerful enough to illuminate it and cost only about $3 to make.

“I love the idea of adding value to things that are inexpensive, things that are affordable, things that we see every day,” said Julio D'Arcy, an assistant professor of chemistry at Washington University and one of the researchers on this project.

The new invention relies on something known as iron oxide, a form of matter in bricks that gives them their red colour. The scientists pumped the bricks with several gases that react with iron oxide to produce a network of plastic fibres. These fibres coat the empty spaces inside the bricks—and conduct electricity.

“What we’re trying to do is:we're trying to make specialized plastics and then we can actually put those plastics inside construction materials,”D’Arcy says. “In the future, a brick wall could potentially serve two purposes at one time:providing structural support and storing electricity produced from renewable energy sources,such as solar panels.”

The technology is still at least a few years away from being ready for the market. And right now the energy that the bricks can store is still not much. But the team is now testing ways to improve brick performance—because it looks like you can find a new purpose for an old brick.

8.What did the researchers turn bricks into?

C. An electricity-storage item.D. A new form of green energy.

9.What does the underlined word “illuminate”in paragraph 2probably mean?

A. Store. B. Light.C. Conduct.D. Transform.

10.What conducts electricity in the bricks?

A. Iron oxide. B. The stored gases.

C. The produced fibres.D. The empty spaces.

11.What is the best title for the text?

A. Old Bricks,New Tricks B. A Bright Future Is on the Way

C. A New Way to Produce Electricity D. Recycled Batteries,Renewable Energy
