Sand is a common sight in the world. But you might not know that sand is also a useful resource (资源).

Sand is the second most-used resource in the world after water, the BBC reported. However, the UN said that sand is not limitless and that we might be running out of it.

Sand is made up of very small pieces of rock, soil and minerals (矿物质). It can take tens of thousands of years to form.

But now we are using sand more quickly than it is being formed. According to the BBC, we use about 15 billion tons of sand every year to build houses, roads and other things.

People also put sand in the sea to make new islands. Singapore, for example, is now 20 percent bigger than it was in 1965. Palm islands are three large man-made islands in Dubai, United Arab Emirates. They took 94 million cubic meters of sand to build.

If people keep using this much sand, it will run out in many places. For example, Vietnam may run out of construction (建造) sand by 2020, Live Science noted.

Since people need so much sand, they are trying to mine (开采) more of it. But this is bad for the environment. Mining sand may cause beaches to disappear and more floods to happen in places close to the sea. Also, this may affect the habitats (栖息地) of many plants and animals.

1.What does the story tell us about sand?

A.It can only be found on beaches. B.It is the most-used resource in the world.

C.It can never be used up. D.It can be used to build houses.

2.According to the passage, which country is using sand to build islands?

A.Singapore and Vietnam. B.Singapore and United Arab Emirates.

C.Britain and America. D.United Arab Emirates and Vietnam.

3.Every year, we use about________tons of sand.

A.94 million B.20 billion C.20 million D.15 billion

4.We are running out of sand because________.

A.there is only a little sand in the world B.we are using sand too quickly

C.we cannot mine enough sand D.our environment is badly polluted

5.In places close to the sea, more floods will happen because of________.

A.overmining of sand B.climate change

C.the increasing size of certain islands D.the death of some plants

Zak’s grandfather, Stan, was very famous. Why? Because he had a very, very, very long white beard(胡子).

One day Zak asked his grandfather, “When you sleep, do you put your beard over or under the quilt?” “I’m not sure. I never care about that,” said his grandfather, “I’ll look tonight.”

Stan got into bed that night and pulled up the quilt. Then he remembered his grandson’s question. Aha! His beard was under the quilt. But wait. Did that feel right?

He lifted his beard from under the quilt and put it above it. This also didn’t feel right. So he put the beard under the quilt again. But he soon felt it would be better if it were out. The beard went in and out—first under the quilt, then over it, under, over, all night long.

Stan spent a sleepless night. In the morning, he was so tired and unhappy that he cut his long beard right off! Stan’s wife was so happy. She advised Stan to cut that beard off many times, but he never did it. Now a simple question made him do that.

根据上述内容,判断下列句子正误,正确的填 T,错误填 F。

1.Stan was very famous for his long white beard.

2.Stan never cared about Zak, his grandson.

3.At the very beginning, Stan’s beard was under the quilt.

4.That night Stan was sleepless and tired because of the question.

5.Stan listened to his wife’s advice to cut the beard off.

It was on the afternoon of the day of Christmas Eve, and I was in Mrs. Prothero’s garden, waiting for cats, with her son Jim. It was snowing. Patient and cold, our hands wrapped in socks, we waited to snowball the cats. The wise cats never appeared. We were so still in the snow that we never heard Mrs. Prothero’s first cry from the bottom of the garden. Or, if we heard it at all, it was, to us, like the cry of the neighbor’s Polar cat. But soon the voice grew louder. “Fire!” cried Mrs. Prothero.

And we ran down the garden, with the snowballs in our arms, towards the house; and smoke, indeed, was pouring out of the dining room.

This was better than all the cats in Wales standing on the wall in a row. We loaded with snowballs, stopped at the open door of the smoke-filled room. Something was burning all right; perhaps it was Mr. Prothero, who always slept there after midday dinner with a newspaper over his face; but he was standing in the middle of the room, saying, “A fine Christmas!”

There was no fire to be seen, only clouds of smoke and Mr. Prothero standing in the middle of them, waving his slipper as though he were conducting.

“Do something,” he said.

And we three all our snowballs into the smoke—I think we missed Mr. Porthero—and ran out of the house.

“Let’s call the police,” Jim said.

“And Emie Jenkins, he likes fires.” But we only called the fire-brigade, and soon the fire-engine came. Mr. Porthero went out just in time before they turned the hose (水管) on.

1.Why were the boys in Mrs. Prothero’s garden?

A.They were about to start a snowball fight.

B.They were waiting to see if there would be any fires this year.

C.They were waiting to hear Mrs. Porthero’s first cry.

D.They were waiting for the neighbour’s cats to appear.

2.The underlined phrase “snowball the cats” (in Paragraph 1) means “__________”.

A.make cats out of snow B.bury cats under the snow

C.throw snowballs at the cats D.play tricks on cats

3.When the boys saw smoke pouring out of the dining room, __________.

A.they were joyful and excited B.they were frightened and worried

C.they were sorry for Mrs. Prothero D.they were worried about Mr. Prothero

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.
