Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?

    Wrong

    New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time.In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—-it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

    Weaving hammocks is an art that takes a sharp eye, a skilled hand and lots of patience. But in Lenwood Haddock's case, being blind works to his advantage. His trained, sensitive hands are acutely aware of every step of the process. Since beginning his craft in 1986, Lenwood has woven about 145, 000 perfect hammocks.

    Lenwood lost his sight in 1973, at age 18, during a hunting accident. “My whole working career has been blind,” he says. He first found a job as a woodworker, but when that organization closed, the North Carolina Division of Services for the Blind connected him with Hatteras Hammocks. On his first day of work. “I did a total of one hammock,” Lenwood recalls, laughing. “And then I came home and lay down to sleep. I lift weights, but I wasn't as tough as I thought until I started weaving.lt takes a lot of energy, and you're standing up all day.”

    In time, however, Lenwood found he had a knack (窍门) for the job. At first he worked on-site at the company, but after a year Lenwood moved his operation to the home workshop where he had worked for 10 years during his woodworking days.

    There, he creates dozens of hammocks each week from ropes in a variety of sizes. One day, he realized the step counter on his phone recorded him walking eight miles without ever leaving his shop.

    The process of weaving a hammock involves making and catching hundreds of loops (环). A single missed stitch (织针) creates a hole that can widen and make the hammock uncomfortable or even dangerous to use. Experienced weavers miss loops sometimes, but to his company's knowledge, Lenwood has never turned in a hammock with even one dropped stitch. Lenwood's skilled fingers are quick to catch and fix any mistakes.

    The company has acquired other brands and changed its name to The Hammock Source. Today, it is the world's largest maker and seller of hammocks, all built by hand.

    However, Lenwood's routine has changed little. He works his fingers back and forth across the rows, looping the rope and pulling it. With every hammock, Lenwood presents himself a perfect product. “I'm not sure how sighted people do it,” he admits.

    SILVER SPRING, MARYLAND — Student engagement (参与) is a goal in schools everywhere. A teacher in the Washington suburbs has found a way to engage and motivate students — by ringing rhythm and fun to mathematics. The approach works well especially for students who speak English as a second language.

Making math fun

The voice heard in the video belongs to mathematics teacher Jake Scott. Most of the performers are his students. "I use rap because it is something that appeals to the students, and also because music aids memory," Scott explains.

    Scott started using rap videos three years ago. So far he has produced nine, including

Scott started using rap videos three years ago. So far he has produced nine, including YouTube favorites Triangle Experts and Quadratic Formulatic, which have been viewed tens of thousands of times. "It is fun and the whole process is something that students appreciate," Scott says.

    Empowering students

    Blair High School principal Renay Johnson is a big supporter. She even appears in Scott's latest video, Undefined Expressions.

"Mr. Scott is very motivating and engaging for students," Johnson notes. "He enjoys what he does. As you know he engages students and mathematics through music. But he is also our wrestling coach. He also sponsors National Honor Society. And he is also a director of after school sports academy. I am lucky to have him here as a teacher."

    Scott was recognized as an outstanding educator last year by the Montgomery County Council. He was also honored as 2011 teacher of the year by an African-American civil rights organization.

    Jake Scott says he wants mathematics to be something that students look forward to learning. And he says the results will help them on a path to college and a career.

    For all the pressures and rewards of regionalization and globalization, local identities remain the most deeply impressed. Even if the end result of globalization is to make the world smaller, its scope seems to foster the need for more intimate local connections among many individuals. As Bernard Poignant, mayor of the town of Quimper in Brittany, told the Washington Post, “Man is a fragile animal and he needs his close attachments. The more open the world becomes, the more ties there will be to one's roots and one's land.”

    In most communities, local languages such as Poignant's Breton serve a strong symbolic function as a clear mark of “suthenticity（原真性）”. The sum total of a community's shared historical experience, authenticity reflects a perceived（感知到的）line from a culturally idealized past to the present, carried by the language and traditions associated with the community's origins. A concern for authenticity leads most secular（世俗的）Israelis to champion（捍卫，维护）Hebrew among themselves while also acquiring English and even Arabic. The same obsession with authenticity drives Hasidic Jews in Israel or the Diaspora to champion Yiddish while also learning Hebrew and English. In each case, authenticity amounts to a central core of cultural beliefs and interpretations that are not only resistant to globalization but also are actually reinforced by the “threat” that globalization seems to present to these historical values. Scholars may argue that cultural identities change over time in response to specific reward systems. But locals often resist such explanation and defend authenticity and local mother tongues against the perceived threat of globalization with near religious eagerness.

    As a result, never before in history have there been as many standardized languages as there are today: roughly 1,200. Many smaller languages, even those with far fewer than one million speakers, have benefited from state-sponsored or voluntary preservation movements. On the most informal level, communities in Alaska and the American northwest have formed Internet discussion groups in an attempt to pass on Native American languages to younger generations. In the Basque, Catalan, and Galician regions of Spain, such movements are fiercely political and frequently involved loyal resistance to the Spanish government over political and linguistic rights. Projects have ranged from a campaign to print Spanish money in the four official languages of the state to the creation of language immersion nursery and primary schools. Zapatistas in Mexico are championing the revival of Mayan languages in an equally political campaign for local autonomy（自治权）.

    In addition to causing the feeling of the subjective importance of local roots, supporters of local languages defend their continued use on practical grounds. Local tongues foster higher levels of school success, higher degrees of participation in local government, more informed citizenship, and better knowledge of one's own culture, history, and faith. Government and relief agencies can also use local languages to spread information about industrial and agricultural techniques as well as modern health care to diverse audiences. Development workers in West Africa, for example, have found that the best way to teach the vast number of farmers with little or no formal education how to sow and rotate crops for higher yields is in these local tongues. Nevertheless, both regionalization and globalization require that more and more speakers of local languages be multi-literate.
