Zheng He made seven heroic voyages to Asia and Africa between 1405 and 1433, which predated the Westerners' Voyages of Discovery by almost a century . Despite Zheng He's remarkable maritime feats , with larger and matchless fleets until World War I , he is ly unknown worldwide compared with his Western counterparts like Columbus and Vasco da Gama . Why ? Sadly , much of the official Chinese records of these voyages were destroyed after his death , by order of his powerful enemies at Court . They were opposed to his expeditions , both on economic and other grounds . Further , the Ming History made only little mention of his exploits . Most surprisingly , not even his date of death and burial place were recorded . Therefore , his final resting place is still a matter of _ .So he became only a legend and folk hero in his life time . However , hardly any Chinese works on him have been translated into foreign languages . Ironically , it was due to a handful of famous Western researchers like prefix = st1 /Needham, Zlevathes and , most recently , Menzies that the world is now more familiar with his greatness . Zhen He's rightful place in Chinese history has been confirmed by none other than Deng Xiaoping in 1984 , when he addressed the nation's People's Congress in Beijing : "...The Ming dynasty , under Yongle Emperor , did wisely pursue an open-door policy resulting in Zheng He's famous maritime expeditions overseas . However , after Yongle's death, Chinadeserted this policy resulting in foreign intervention andChina's final humiliation during the 19th century . The open-door policy is therefore the way forward forChina." Following a more realistic overall appraise by scholars East and West of Zheng He's achievements , his standing as one of the greatest maritime explorers of all time has at last been firmly recognized worldwide . Zheng He's success in his maritime expeditions overseas mainly resulted from_. A) his braveness and perseverance B) Yongle Emperor's open-door policy C) his strong curiosity to know about Africa D) the support from his friends and family

One baby born with a defective windpipe now has hope of breathing normally thanks to 3-D printing technology, NPR reported. Garrett Peterson, now 18 months old, was born with tracheomalacia , leaving him unable to breathe. The condition terrified his parents, who turned to specialist Dr. Glenn Green at the University of Michigan for a possible treatment. Along with Scott Hollister, a biomedical engineer who runs the university's 3-D printing lab, Green designed a device that can hold open Garrett's windpipe until it's strong enough to function independently. After taking a CT scan of Garrett's windpipe to make a replica of it, they made the "splint" with a 3-D printer. "It's like a protective shell that goes on the outside of the windpipe, and it allows the windpipe to be tacked to the inside of that shell to open it up directly," Green told NPR. On January 31, Garrett had his surgery. Surgeon Dr. Richard Ohye opened up Garrett's chest and saw that his windpipe had completely collapsed and one of his lungs was completely white -- a condition Ohye had only seen in dead bodies. After eight hours of surgery and careful placement of a splint on either side of Garrett's windpipe, it was time for the big test: What would happen when they let air flow through the windpipe into Garrett's lungs? Though he still remains in the hospital, Garrett has gotten stronger and needs less assistance breathing in the weeks since his surgery. His parents are overjoyed, saying he's starting to act more interactive and alert. As Garrett grows, the splint will expand and eventually dissolve in his body as his own windpipe strengthens enough to work independently. 3-D printing technology has allowed doctors to help patients in ways that they hope will continue to grow. "We're talking about taking something like dust and converting it into body parts," Green said. "And we're able to do things that were never possible before." What does the author mainly talk about in the passage? A) The introduction of 3-D printing technology by medical workers. B) The development of 3-D printing technology by engineers. C) The use of 3-D printing technology in saving a baby. D) The Potential of 3-D printing technology in surgery.

Ques: Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life. But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests. The research found that people who watched a movie in 3D improved cognitive skills, compared to those who watched it in 2D. The research was led by neuroscientist Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney filmBig Hero 6in either standard format or RealD 3D. They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later. According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times. Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future. "These findings are more significant than you might think," he said. "It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline." A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life--something Professor Brendan Walker from Thrill Laboratory...

A good brand agency can create for you a brand identity of your products. Having the best agency to help with your business, no matter how small, can be one of the biggest steps you can take in letting the world know and get familiar with your products and brands. Brand agencies work hand in hand with the company in advertising the brand and its products. The company has to tell the agency how they would like the public to see their products. The agency then talks with the company about the progress of the brand in the market. Working with brand agencies is a two-way street. When the company is happy and satisfied with how the agency has advertised the brand, the trust the company has in the agency grows. Similarly, when the agency does well in its work, the company's brand and products get good ideas from buyers and the market. Regarding the identity of the brand, agencies can help a lot in this aspect. For a brand to have a lasting influence on the buyers, an identity of the brand needs to be formed. If the brand is good, then buyers will feel at ease buying the products of this brand. The text is mainly written for _ . A) customers B) salesmen C) researchers D) managers
