A Teenage Inventor
The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.
Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia’s method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia’s method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn’t have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.
Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.
“What affects one country affects everyone,” Olivia told CNBC. “We have to work together to find answers to the huge challenges which cause harm to the global health.” The Connecticut’s teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.
Olivia hopes her success will inspire other girls interested in science and computers. “I would just encourage girls to try it in the beginning, and remind them that they don’t have to feel naturally drawn or feel like they have a special talent for maths or science,” she told CNBC, “but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests.”

No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock ‘n’ roll. Long-ago builders could have attached wooden poles to the stones and rolled them across the sand, the scientists say.
“Technically, I think what they’re proposing is possible,” physicist Daniel Bonn said.
People have long puzzled over how the Egyptians moved such huge rocks. And there’s no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.
The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.
Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
However, physicist Joseph West thinks there might have been a simpler way, who led the new study. West said, “I was inspired while watching a television program showing how sleds might have helped with pyramid construction. I thought, ‘Why don’t they just try rolling the things?’ ”A square could be turned into a rough sort of wheel by attaching wooden poles to its sides, he realized. That, he notes, should make a block of stone “a lot easier to roll than a square”.
So he tried it.
He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.
They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的) path.
West hasn’t tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn’t have needed to carry cattle fat or water to smooth the paths.
1.It’s widely believed that the stone blocks were moved to the pyramid site by .
A. rolling them on roads B. pushing them over the sand
C. sliding them on smooth paths D. dragging them on some poles
2.What does the underlined word “it” in Paragraph 7 refer to?
A. Rolling the blocks with poles attached.
B. Rolling the blocks on wooden wheels.
C. Rolling poles to move the blocks.
D. Rolling the blocks with fat.
3.Why is rolling better than sliding according to West?
A. Because more force is needed for sliding.
B. Because rolling work can be done by fewer cattle.
C. Because sliding on smooth roads is more dangerous.
D. Because less preparation on paths is needed for rolling.
4.What is the text mainly about?
A. An experiment on ways of moving blocks to the pyramid site.
B. An application of the method of moving blocks to the pyramid site.
C. An argument about different methods of moving blocks to the pyramid site.
D. An introduction to a possible new way of moving blocks to the pyramid site.

Summary writing.
Craig Silverman, a journalist, tracked rumors circulating online in 2014 and found that shares and social interactions around fake news articles dwarfed those of the articles that debunked(戳穿) them. According to Silverman, fake news stories are engineered to appeal to people's hopes and fears, and aren't constrained by reality, which gives them the edge in creating shareable content.
You might think you're immune to(对…免疫) falling for these lies, but a wealth of research disagrees. Back in the 1940s, researchers found that "the more a rumor is told, the greater is its plausibility(可信度)". This means a rumor born out of mild suspicion can, by gaining currency, shift public thinking and opinion.
It gets worse：studies show that students tend to place enormous trust in search engines to deliver accurate results, often turning to the first result returned-a concern given that fake news can appear in the section for news stories displayed, for example, above Google's search results.
So how can you protect yourself from digital lies? An easy step is to check who produced it. Often itis clear from the URI, that a website is pretending to be reputable by stealing the name and style of another publication. Also, take a look at the other stories on the website. Fake news websites often have nothing but fake content. If all the stories are outrageous, consider it a red flag. Finally, search for coverage of the story elsewhere, if a story is false you'll often find it debunked on websites such as snopes.com.
