Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue. Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003.This process is called biofabrication . It requires special printing equipment and a special kind of ink. Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer. Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process. The bio-inks are placed in three dispensers , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released. Michael Yost is a leader of the research team. He says the printing process is fully automated-- machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types. The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs. But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive. Michael Yost hopes that more people will believe in the benefits of biofabrication. "Tissue... What can we know about the bio-inks? A) They are the necessities of bio-printing. B) They only contain proteins and glucose. C) They can be placed in the traditional printers. D) They are available in our local drugstores.

Ques: Local officials in Beijing promised to furtherprotect the city's cultural heritage , in particular the narrow streets known as Hutong. Hutong are commonly found in the cities of North China, but they are at risk. Beijingis currently believed to have fewer than 1,000 Hutong, most of which are nearthe Forbidden City. Only 60 years ago, thenumber was 3,250. In the old districts of Dongcheng and Xicheng, which cover 62square kilometers, some people will be asked to move from Hutong houses toavoid further damage to the ancient architecture. "On average more than 100,000 people visit the Forbidden City during the National Day holidays. Thevisits put pressure on the protection of cultural relics," said Huang Yan,director of the Beijing Municipal Commission of Urban Planning, adding that Hutongshould be protected from human damage. The government focused on how the protection planswere carried out and how the management of cultural heritages worked. WangShaofeng, head of the Xicheng district government, said the area has 182cultural relics, many of which were built as far back as the Yuan Dynasty(1271-1368). The district of Xicheng has 1.28 million residents in its 57square kilometers of land. "The most efficient way is to decrease the localpopulation to reduce the possibility of causing harm to the heritage," Wangsaid. "Each community has been required to report thestatus of its cultural heritage, especially Hutong, and any actions to damagethe heritage will be punished," Wang said. No one knows for sure how many Hutong will be leftin the coming 100 years. According to Huang Yan, what is the main causeof the damage to cultural relics? A) Visitors' activity. B) Residents' attitude. C) Communities' behavior. D) The governments' policy.

Question: The dream of flying into outer space, cherished by the Chinese people for centuries, will soon come true. China launched its fourth unmanned spacecraft "Shenzhou IV" on December 30 at the Jiuquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive( )and successful launch of China - made rockets since October 1996. This launch has made it more realistic for China to send a person into space on its own following Russia and the USA. Qi Faren,leading designer of the spacecraft system, said all the functions designed for manned flights have withstood the test of three previous, successful launches and return landings of the "Shenzhou" spaceships. China launched the "Shenzhou I ", "Shenzhou II "and "Shenzhou III "spacecrafts in 1999,2001 and 2002 respectively. "Shouzhou IV" was to make it a more comfortable place in which astronauts can live and work. All parts of the application system for manned flight are aboard the "Shenzhou IV"craft in all test flights. China's manned flight programme began in 1992. A number of unmanned test flights will be launched before Chinese astronauts are sent into space. Leading scientists in charge of China's manned space programme said the successful launch of the "Shenzhou IV" laid a solid foundation for the country's future task of sending Chinese astronauts to outer space. The spacecraft returned to the earth on January 5, after completing seven experiments in space. Officials at the centre said that" Shenzhou V", a manned spacecraft, is expected to be launched later this year. .Which is the most suitable title for the passage? A) The Successful Launching of "Shenzhou IV ". B) The Landing of "Shenzhou IV ". C) Chin a's Manned Flight Programme. D) The Third Country Sending a Person into Outer Space.
