At one time or another in your life you have probably done origami, even if it was just making a paper airplane or something more complicated like a paper crane. The chances are that as you did it, you reflected on how inventive this traditional art is. Animals, boxes, flowers, boats: it all can be created from a single square or rectangular sheet of paper simply by folding it. No cutting, no pasting.
But did you ever stop to think how the same techniques might be applied to engineering? Equipment that could be of real practical use? Origami meets the demand for things that need to be small when transported and large when they arrive, like the everyday umbrella. In fact, origami-inspired creations have already flown in space; in 1995, Japanese engineers launched a satellite with solar panels that folded like a map.
“It’s now mathematically proven that you can pretty much fold anything,” says physicist Robert J. Lang, who quit his engineering job eight years ago to fold things full time. Lang, an origami enthusiast since age six, advised a advised well-known ear manufacturer the best way to fold an airbag into a dashboard. He is currently working on a space telescope lens that, if all goes according to plan, should be able to unfold to the size of a football field.
At the other end of the scale, researchers are also working on tiny folding devices that could lead to breakthroughs in medicine and computing. There’s no doubt that computers of the future may contain tiny, folded motors or capacitors for faster processing and better memory.
Applications for origami engineering go further than many of us might imagine. “Some day,” says MIT’s Erik Demaine, “we’ll build reconfigurable (可重构的) robots that can fold on their own from one thing into another, like Transformers. Too much like science fiction to be true? Maybe—though you certainly wouldn’t want to bet against it.”

Even if you’ve never been to Phoenix, you know this about the place It’s hot. From June to September, the temperature can easily surpass the century mark. But that doesn’t stop hikers from attempting the 1.3-mile hiking to the top of the city’s famed Camelback Mountain. Signs warn that the trail is “extremely difficult”. If you continue, a posted checklist suggests at least a liter of water per person. And if you’re still not stopped, another sign farther up declares: “If you’re halfway through your water, turn around!”
Unfortunately, many people to not take the warnings seriously. Fortunate y, Scott Cullymore does. The 53-year-old Cullymore can be found hiking up and down Camelback a couple of times a day, giving out cold bottles of water to worn-out hikers. He has helped hydrate so many hikers that he has earned a heavenly nickname: the Water Angel.
Cullymore was on Camelback Mountain one day in 2015 when a British tourist died after being lost for nearly six hours in the July heat. That experience inspired him to start helping people caught unaware by the cruelty of Mother Nature. “They underestimate the mountain, and they overestimate what they can do, and they get themselves in trouble.” he warned.
One hiker who was offered water agrees. “You think you know the heat, but then you get out here in the desert and it surrounds you like a blanket,” said Austin Hill, who was hiking with a high school friend. They were lucky, he said pointing to Cullymore. “We ran into this Good Samaritan here.” And with that, the Water Angel goes in search of another hiker in need.
1.What is the first paragraph mainly about?
A.The risks involved in the hiking.
B.The seriousness of the warnings.
C.The distribution of signs that warn hikers.
D.The influence of the temperature on hikers.
2.Why did some hikers on Camelback Mountain get in trouble?
A.They were not well trained in hiking.
B.They forgot to take enough water with them.
C.They were too optimistic about the situation.
D.They were not fit enough to hike the mountain.
3.What can we know about Austin Hill?
A.He agreed to help others. B.He was saved by Cullymore.
C.He hiked alone in the desert. D.He regretted taking a blanket.
4.What is the best title for the text?
A.The Camelback Mountain B.Surviving the Heat
C.Hikers in Need D.The Water Angel

Advertising plays a major role in the competitive business world. Many industries take advantage of the power of advertising to attract or to win customers away from their business competitors. The influence of advertising is so huge that it causes many people to buy things that they don't want at the start.
Advertising encourages people to buy things they don't want through misleading ideas. Advertising is proven to be a successful tool to stress the features of their product to the public even though it's regarded undesirable such as cigarettes,drugs,alcohol and so on. For example,Dunhill,a cigarette company which sponsors many football teams,seems to be promoting cigarettes to the public. Without the sponsorship,the company will be less known to the public,resulting in fewer sales of cigarettes.
Besides that,advertising has a large influence on the decisions made by the people in their everyday life. Many businesses use advertising as a form of promoting to create awareness about their product in the market. For instance,in a fast food industry,the introduction of a new flavor of burger needs advertising to reach the public while the other burgers require advertising to increase sales. Children,especially,are easily influenced by advertisements and will have the desire to dine at fast food restaurants after that. Although fast food is bad for health,it has successfully become appealing to the public through advertising.
However, advertising plays a part in helping customers to compare a product in terms of price, quality, reliability and so on. Without advertising, it will be very difficult for customers to judge the worthiness of a product. For example, advertisements published by various companies have given the customers the opportunity to choose wisely when they are purchasing an item. Without the power of advertising, customers will be stuck to a brand which may not offer the best choice.
