八年级英语单项填空简单题查看答案及解析

Imagine that the battery on your mobile phone has run out. You can't make any calls for help and no one can contact you. You are all alone--- well, not quite. Just reach into your pocket and take out a piece of sugar. Put it into the battery, wait a minute and you are back on the phone.

Thanks to a couple of American scientists, this situation could become real. Swadesh Chaudhuri and Derek Lovely have invented the “bacteria battery”. This kind of battery gets its power from bacteria that eats sugar and turns it into electricity.

“This is a special organism (有机体),”Lovely said. “You can get enough electricity to power a cell phone battery for about four days from a spoonful of sugar.”

In the past, bacteria batteries have been expensive and not long-lasting. But this battery uses a more efficient bacterium that can turn 80 percent of sugar into electrical energy. This is 30 percent more than similar batteries can manage.

The bacteria battery could become as small as a household battery. It is also cheap and stable, because sugar can be taken from waste and crops.

But the sugar-to-electricity process is slow: it could take weeks for the bacteria to change a cup of sugar into electricity.And it produces “greenhouse” gases which pollute the environment.

The scientists understand there is a lot more work to be done. “It is still young,” said Lovely.

“Where we are now is where solar power was 20 or 30 years ago.”

He also believes the battery will be used in scientific equipment at the bottom of the ocean.

Other ideas include using sugar in the blood to run medical devices in the human body and taking sugar from animal waste to provide energy to power homes in rural areas.

1.What's the passage mainly about?

A.How to change sugar into electricity. B.A scientific invention of a new type of battery.

C.How to use the new bacteria battery. D.A new kind of mobile phone and its future.

2.Which of the following is NOT the advantage of the newly-developed battery?

A.Convenient. B.Stable. C.Inexpensive. D.Quick.

3.Which of the following are the scientists working on to improve the new battery?

A.Increase the bacteria. B.Solve the pollution problem.

C.Bring down the price. D.Change the size of the battery.

4.What does the underlined sentence actually mean?

A.The bacteria battery shares some similarities with solar energy.

B.Scientists will continue their work until they find solar power.

C.There is still much room for the improvement of the bacteria battery.

D.The bacteria battery will be as popular as solar power in twenty or thirty years.

5.According to the last paragraph, who will find the bacteria battery less useful?

A.Divers. B.Farmers. C.Doctors. D.Architects.
