1 . Greying Population Stays in the Pink

Elderly people are growing healthier, happier and more independent, say American scientists.

In the last 14 years, data have been gathered on the health and lifestyles of more than 20,000 people over 65. Researchers say high blood pressure and circulation problems and other diseases of old age are troubling a smaller proportion every year.     1     . It really raises the question of what should be considered normal ageing, because the problems with old people are often not appearing until they are 70 or 75.

    2    . But there may be other contributing factors. Improvements in childhood nutrition gave today’s elderly people a better start in life.

One interesting fact is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their education live an extra seven years.     3    .

The survey also assessed how independent people over 65 were, and again found a striking trend. Their self-reliance is probably linked to an increasing use of home medical aids, such as raised toilet seats and bath seats.     4    .Those elderly people who were independent were more likely to stay healthy in old age.

    5    . Researchers found that elderly people who felt emotionally isolated maintained higher levels of stress hormones even when asleep. So they suggest that older people live best when they feel independent but know they can get help when they need it.

2 . Facial recognition is a new technology built into all sorts of applications. It's also one of the more controversial technologies pioneered today, as it sets up deep questions regarding security versus privacy rights, and how these facial recognition applications can be safely and fairly applied.

Modern facial recognition is clearly dependent on specific technologies and algorithms (算法) that we've built during the machine learning and artificial intelligence era of the early 21st century. Specifically, most cutting-edge facial recognition programs feature a type of neural network called a convolutional (卷积) neural network (CNN). The system uses convolutions as well as other algorithm work in successive stages to do complex analysis of an image, and even identify people, animals, objects or settings through advanced analysis.

One primary piece of functionality in the CNN is feature detection. First, the face must be identified within the image context, so that the facial features can be analyzed. Methods such as the Viola-Jones are used to break down an image through color shift and local analysis of group pixels to find features like noses, ears, eyes, etc. The same facial recognition neural networks will often utilize ratios—such as the ratio from eyes to hairline, from ears to nose, or other stock facial ratios that can help with facial recognition. The image is then compared to all known faces to uniquely identify the identity of that person.

So, with all this winning technology the facial recognition engine can be surprisingly adept at learning how to recognize a particular individual’s face in a crowd. Facial recognition software is applied in payment processing to substitute cards with faces, for access and security purposes, and to identify criminals.

Primarily, companies that have used abundant public Internet images to pull together training sets for sophisticated facial recognition programs face blowback and resistance from some of their customers, including law enforcement departments, and from U.S. legislators, consumer advocates and citizens at large.

The trade routes are of great importance. In march, the Suez Canal, one of the world's most important sea trade routes,     1     (block) by a ship, causing an epic maritime traffic jam of nearly 300 ships between Europe and Asia. Besides the Suez Canal, China's ancient Silk Road also played     2     important role in trade and cultural exchanges between China and Europe.

In early history, The Silk Road was the most important trade route,     3     (mark) the beginning of globalization. As the first route     4     introduced the Eastern world to the Western civilization, the Silk Road in China can date     5     the Han dynasty in ancient China. In the following years in history, many great figures had made significant     6     (contribute) to the development of the Silk Road.

Though the Silk Road was mainly a trading route, it was     7     (benefit) to each other in the first place. It     8     (actual) made great attraction to the development of the civilization of the world, opening long-distance political and economic communication between Europe and Asia. The ancient Silk Road is more like a historical textbook, enabling people from different cultures and regions     9     (comprehend) what happened during the ancient time. Up to now, the Silk Road in China     10     (bring) great attraction to the tourism in China even in the world.

4 . Introduction to Sanxingdui Museum

Situated in the northeast of the state-protected Sanxingdui Site by the bank of the Yazi River in Guanghan — a city famed for its long history and splendid culture, Sanxingdui Museum is a modern theme museum which is 40 kilometers to the north of Chengdu.

Covering a total area of 530 yields, Sanxingdui Museum had its foundation laid in August 1992, and opened to the public in October 1997. Featured for its relics, architecture, demonstration and gardens, the museum has become a place of cultural and tourist attractions enjoying prestige both at home and abroad and one of the three exquisite spots Sichuan has offered to the world tourism.
