“Human influenza viruses can survive and be infectious for several days when they are deposited on banknotes,” according to the latest study by Yves Thomas and his colleages in Switzerland. Scientists put different types of flu virus onto Swiss franc notes and found that they could survive from a few hours to more than a week. The results depended on the type of flu virus.
According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(無孔樹脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.

Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas(別墅), luxury cars and twinkling lights from the shopping center that he sees through the window.
Yang works for a software company in Zhongguancun. He dreams of such a life, away from poverty, and that hope has kept him in Beijing for three years since he graduated from university.
Soon Yang squeezes his way off the bus to the reality of his life: his home—a 10-square-metre room that costs 550 yuan(81 US dollars) or about one-fifth of his salary in rent every month. It’s very cold inside the house as it has no central heating system. He has to stand the long and cold winter. Determined to achieve his dream, Yang says he has changed jobs “numerous” times in the past three years and is considering quitting his present job.
Yang’s frustration over his life as a migrant(移民) is shared by many other graduates that have moved into big cities. Together they have come to be called the “ant tribe”, a term created by Chinese sociologists to describe the struggles of young migrants, who, armed with their diplomas, flood to big cities in hopes of a better life only to put up with low-paying jobs and poor living conditions. They share every similarity with ants. They live in colonies in crowded areas. They’re intelligent and hardworking, yet unknown and underpaid. The term, sociologists have said, also reflects their helplessness in a world governed by the law of the concrete jungle—only the strongest survive.
A survey in Ant TribeⅡ found nearly 30 percent of the “ants” are graduates of famous key universities—almost three times the percentage of 2009. Most have degrees in popular majors, such as medicine, engineering, economics and management. In addition, 7.2 percent of the “ants” have at least a master’s degree compared to 1.6 percent in 2009. Most said the economic recovery did not really improve their financial situations, and 66 percent said their incomes fell short of their expectations, the survey also found.
For two years, Lian Si, a post-doctoral fellow at the Center for Chinese and Global Affairs of Peking University, who has studied the phenomenon, led a team of more than 100 graduate students to follow the groups in university towns like Beijing, Shanghai, Guangzhou, Wuhan and Xi’an. Lian evaluates the total population of the “ant community” in major cities at one million across China, with about 100,000 found in Beijing alone. Lian predicts that an increasingly challenging job market will see the ant tribe growing further in number. Another 6.3 million graduates are expected to join migrant workers and other job hunters in what promises to be a fierce labour competition.
The ant tribe’s embarrassing living situations have become a serious social issue, and the government should develop “second-and-third-tier cities” to attract more graduates from big cities. However, “ants” expect more study and training opportunities in big cities, which keeps them in positive mindsets despite their situations. As in the case of Yang, he is optimistic about getting a new job soon, having received eight interview offers in a week after sending out his resume. The prospect of landing a higher-paying job keeps him hopeful of moving out of the slum district(貧民區(qū)) soon. The sooner the better.

Several hundred strangers received “l(fā)ove letters” from a young man on the street. The letter was written and given out by Yang Yang, a student majoring in human resources at Chongqing University of Science and Technology，who hoped to show his disappointment with job hunting.

    Yang’s story has caught media attention perhaps because it is similar to those of millions of recent graduates seeking jobs and struggling for survival in the country’s wealthiest cities. They have diplomas, rather than professional skills，and come to big cities in hopes of better lives, only to find low-paying jobs and poor living conditions.

They are China’s “ant tribe(蟻?zhàn)?”, a term created by sociologist Lian Si from Peking University in his 2009 book, Ant Tribe. “They’re so similar to ants. They share small and narrow living areas. They’re intelligent and hard-working, yet nameless and underpaid.” The term also speaks to their helplessness in a world governed by the law of the jungle -- only the strongest survive.

A survey in Lian’s another book published this year, Ant Tribe II, found nearly 30 percent of “ants” are graduates of famous universities—almost three times last year’s percentage. Most had degrees in popular majors. In addition, 7.2 percent of "ants" have at least a master’s degree compared to 1.6 percent in 2009.

    An “ant’s” average monthly salary is l, 904 yuan, with about 64 percent of them earning less than 2,000 yuan a month.

  Another survey in the 2010 Annual Report on the Development of Chinese Talent found more than 1 million “ants” live in big cities.

   “Most ants are from rural families or small towns, and their experiences in universities didn’t arm them well enough to fight with competitors in big cities’ employment markets.” Professor Zhang Ming at Renmin University of China said.

The “ant tribe’s” embarrassing living situations have become a serious social problem, and the government should develop smaller cities to attract more graduates from big cities, Zhang

believed.

    However, “ants” expect more study and training opportunities in big cities, which keeps them positive despite their situations.

There is a saying in French—“Si vieillesse pouvait, si jeunesse savait”—which means roughly “if age had the ability, if youth had the knowledge.” I was reminded of this saying the other day when I saw an interview with a distinguished Asian neurosurgeon(神經(jīng)外科醫(yī)生), now retired, about the impact of computer technology on modern surgery.
He was referring to the difficulty people of his age had in using the new techniques, but also to the fact that younger surgeons, who are more comfortable with the technology, lack some of the wisdom of experience.
It struck me that this problem is not just confined(局限于) to specialized fields such as medicine, but is widespread in modern life. There are many areas where the rapid growth of technology has widened the generation gap.
Young people are at ease with modern technology and propose all sorts of ways for using and developing it. But they often lack the experience needed to see further into the future to the possible dangers that a particular development may cause.
Older people see all sorts of difficulties and dangers, but are sometimes ignored, or even accused of being against progress, if they point out potential problems. Equally, they may see potential uses, but not have the technical skills to put them into practice themselves or the trust in the younger generation to do so.
Enthusiasm and inexperience come into conflict with caution and arrogance, usually with unsatisfactory results for both sides.
What is needed is the development of a partnership, based on mutual respect, which can deliver real progress by combining enthusiasm and caution in a constructive way, rather than in conflict with each other. The old need to give the younger generation the time, the resources and, above all, the authority to develop new ideas and use their skills. In exchange, the young need to turn more actively to the older generation to seek their advice and exploit their greater experience of the world in foreseeing and overcoming potential problems.
【小題1】The passage is mainly about ________.
