3岁时查出患有进行性肌营养不良（俗称肌无力）症，从小学五年级开始，由父亲背着上学、放学，他克服了身体困难，顽强努力。在全校师生的帮助下，他坐着轮椅顺利参加了今年的高考。这就是郑州九中2016届毕业生张昊的故事。

    在2016年6月12日上午举行的郑州九中高三毕业典礼上，毕业生张昊同学在父亲的陪伴之下坐着轮椅回到学校，为学校赠送一面锦旗，上面写着离别赠言：“三年倾情关爱，一生不忘；九中师德校风，举世典范!”

    张昊的同桌田宝宏说，“张昊做到了常人做不到的，给了我们更多对生命意义的理解和敬畏，也以最阳光的方式感动并砥砺了你我，未来，我们将继续在这个学校，让优者更优，弱者变强！”

    张吴在日记中曾写道，“我的学业常遭阻断，往往三天两头‘休假’，不过这也许算不得糟糕，换换环境不至于干扰一颗求知的心……父母的繁忙与我的赢弱造就了这一切，还有个副产品：丢三落四，比如临工作前忘记为我留一盏灯，导致了我在傍晚时分因光线不足而终止学习，这实在也并不算糟糕，丢下作业本，我能捕捉到迷人的夜景。从高处远眺，万家灯火美不胜收……一切都有，还算不得糟糕……”

   Do you know the Chinese saying “He who doesn't reach the Great Wall is not a true man”? Mr. White knows it. Next month he is going to Beijing with his wife. They are going to visit the Great Wall. They are staying in Beijing for about a week. They have a lot of Chinese friends there, so they are visiting them. Then they're flying to West Lake in Hangzhou. They are going boating there and staying there for about three days. Mr. White knows that the Yellow Mountain is very famous in China. So they’re going to Anhui to go hiking in the great mountain. After two days in Anhui they'll have to go back to Sydney.
   “I'm taking lots of photos in China. When I get back to Sydney, I am going to show the photos to my friends. I want my friends to know more about China.” said Mr. White.

    There is a breakthrough in building aircrafts. Bendable wings covered with overlapping(部分重叠) pieces resembling fish sizes could be used to build swifter, fuel-efficient aircraft, a new study finds.

    Nowadays, conventional aircrafts typically rely on ailerons (副翼) to help control the way the planes tip as they fly. However, when the Wright brothers flew the first airplane, Flyer 1, over a century ago, they used no ailerons but wires and pulleys that twisted the wood-and-canvas wings, to control the plane.

    Scientists have long sought to develop aircrafts that can alter their wings during flight, just as birds can. However, most previous attempts have failed because they relied on heavy mechanical control structures within the wings. These structures were also complex and unreliable, said Neil Gershenfeld, a physicist and director of the Center for Bits and Atoms at Massachusetts Institute of Technology (MIT).

    The new wing consists of a system of tiny, strong, lightweight modules. The shape of the wing can be changed uniformly along its length using two small motors, which apply a twisting pressure to each wingtip. These wings are covered in “skins” of overlapping strips of flexible material resembling fish sizes. These strips move across each other as the wings alter, providing a smooth outer surface, the researchers explained.

    Wind-tunnel tests of these wings showed that they at least matched the aerodynamic properties of conventional wings, at about one-tenth the weight. Initial tests using remotely piloted aircrafts made with these wings have shown great promise, said Benjamin Jenett, a graduate student at the Center for Bits and Atoms at MIT.

    The new modular structures the scientists developed could be manufactured quickly in mass quantities and then installed by teams of small robots. These modular structures also can be disassembled more easily, making repairs simpler.

    “Still, the first aircraft built using this strategy will not be a passenger jet, ”Gershenfeld said. “Instead, the technology will likely first be tested on unmanned aircraft, leading to drones (无人机) that can fly for a long time, to help deliver internet access or medicine to remote villages and do some rescue works.”
