Article: Testing new drugs for safety and effectiveness is a costly process in the United States. It also can take:lot of time. Some scientists are now designing silicon computer chips that act like human organs. The scientists think they have found a way to make the process faster and more economical. The silicon computer chips are smaller than a child's hand. Each one has living cells that act and react like a human organ. The chips are being created as part of a program to test the safety of drug compounds. It is called the Tissue Chip for Drug Screening Program. It is a project of the US National Center for Advancing Tmnslational Sciences, or NCATS. Danilo Tagle is the center's Associate Director. He says a three-dimensional computer chip can be designed to act like a human lung. Some computer chips contain very small models of the human digestive system. They copy the real function or duties of the human stomach and intestine , moving when breaking down food. Drugs are added to the tiny organs for testing through instruments known as micro-tubes. Experiments with the tissue chips have produced more detailed information than tests using animal or cell models. NCATS just announced$17 million in grants to develop an entire human organ system over the next three years.
Question: Why are scientists designing silicon computer chips acting like human organs?
Options: (A) To treat the patients whose body organs don't work well. (B) To examine the health condition of human organs. (C) To make testing new drugs faster and cheaper. (D) .To further study the function of human organs.

Article: On the second day of the World Internet Conference themed with cybersecurity and international cooperation held in Wuzhen, an official with China's network emergency watchdog said that 6,118 domestic websites have been controlled by the United States, according to Shanghai Securities News. Among the hacked websites in the first half of this year, 48.8 percent were under the thumb of overseas IP addresses, said Huang Chengqing, director-general of the National Computer Network Emergency Response Technical Team and Coordination Center (CNERT/CC). He added that the US contributed the most, followed by Hong Kong, which controlled 3,097, and South Korea with 2,307. Among the overseas IP addresses inserting backdoor programs in domestic websites, the US accounted for 29.3 percent, South Korea for 6 percent and Hong Kong for 5 percent, he said. In addition, 4.9 percent of government websites have been attacked, and 3.2 percent inserted with backdoor programs. Huang also said that the number of Chinese computers affected by Trojan Horse viruses reached 190,000 in the six-month period. To safeguard cybersecurity, the CNERT/CC has cooperated with the Association of Southeast Asian Nations, and built relationships with 59 countries and 127 organizations. Over the past two years, the center dealt with more than 15,000 cross-border online security cases.

Article: "This past year has been one of great celebration for many. The enthusiasm which greeted the Diamond Jubilee was, of course, especially memorable for me and my family. It was humbling that so many chose to mark the anniversary of a duty which passed to me 60 years ago. People of all ages took the trouble to take part in various ways and in many nations. But perhaps most striking of all was to witness the strength of fellowship and friendship among those who had gathered together on these occasions. On the barges and the bridges and the banks of the river there were people who had taken their places to cheer through the mist, undaunted by the rain. That day there was a tremendous sense of common determination to celebrate, triumphing over the elements. That same spirit was also in evidence from the moment the Olympic flame arrived on these shores. The flame itself drew hundreds and thousands of people on its journey around the British Isles, and was carried by every kind of deserving individual, many nominated for their own extraordinary service. As London hosted a splendid summer of sport, all those who saw the achievement and courage at the Olympic and Paralympic Games were further inspired by the skill, dedication, training and teamwork of our athletes. In pursuing their own sporting goals, they gave the rest of us the opportunity to share something of the excitement and drama. We were reminded, too, that the success of these great festivals depended to an enormous degree upon the dedication and effort of an army of volunteers. Those public-spirited people came forward in the great tradition of all those who devote themselves to keeping others safe, supported and comforted. For many, Christmas is also a time for coming together. But for others, service will come first. Those serving in our armed forces, in our emergency services and in our hospitals, whose sense of duty takes them away from family and friends, will be missing those they love. At Christmas I am always struck by how the spirit of togetherness lies also at the heart of the Christmas story. A young mother and a dutiful father with their baby were joined by poor shepherds and visitors from afar. They came with their gifts to worship the Christ child. From that day on he has inspired people to commit themselves to the best interests of others. This is the time of year when we remember that God sent his only son 'to serve, not to be served'. He restored love and service to the centre of our lives in the person of Jesus Christ. It is my prayer this Christmas Day that his example and teaching will continue to bring people together to give the best of themselves in the service of others. I wish you all a very happy Christmas.
