1 . Teachers say that the digital age has had a good influence and a not-so-good influence on American teenagers. More than 2,000 middle school teachers took an online survey. Researchers also spoke with teachers in some groups. Most teachers think the Internet and digital search tools have had a mostly positive (积极的) influence on their students’ research habits and skills. But at the same time, some teachers also point out some problems in teenagers’ using digital search tools.
The Pew Internet Project did the survey with the College Board and the National Writing Project. Judy Buchanan is the director of the National Writing Project and a co-writer of the report. She says digital search tools are helping students learn more, and learn faster. “Both teachers and students really welcome these tools because they make learning exciting. And the goal（目的）is to really help students become creators of something meaningful, and not just users of the online information.”
But one problem the survey found is that these technologies make teenagers have short attention spans (持续时间). As there is lots of information about different subjects on the Internet, teenagers’ attention is easily drawn away from their research.
Another problem the survey found is that many students trust the information they find on the Internet too much. Judy Buchanan says these students have not developed the skills to judge (判断) the online information. They need to learn a lot to tell if the information is believable. It’s something that really has to be paid attention to.
One more problem the survey found is something that might not seem like a problem at all: being able to quickly find information online. Many students think “doing research” now means just doing a quick search on Google. Teachers say the result is a drop in the wish and ability of their students to work hard to find answers. That is, they are depending too much on search engines and do not make enough use of printed books or research librarians.
Many teachers also say that the Internet makes it easy for students to copy work done by others instead of using their own abilities.

2 . Every day Yang Hongwei takes the bus home from work, staring silently at the European-style villas(别墅), 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 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 labor 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(贫民区) soon. The sooner, the better.

3 . “Birds” and “airports” are two words that, paired together，don’t normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that is for birds.
Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区）in the northern coastal city of Tianjin is, of course,not an actual airport. Rather，it's a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway. Over 50 species of migratory (迁徙的）water birds，some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.
Located on a former landfill site，the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However，instead of duty-free shopping，the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles.
“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city---China’s fourth most populous----that would certainly benefit from a new pair of healthy green lungs•

Sharing bread, whether during a special occasion (时刻) or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition hits its roots in the custom of sharing bread.
Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread represent blocks of gold for prosperity (兴旺) in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies (预示) success in the New Year for the person who receives it.
Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity.
Nutrition is necessary for life, so it is not surprising that food is such an important part of different cultures around the world.

5 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
