   “Can I get a light?”This question is the commonest among smokers. What if this question is to come from an unusual source? The National Health Promotion Foundation uploaded an anti-smoking advertisement onto YouTube. The anti-smoking ad has quickly been known as the“most powerful anti-smoking ad”.

The anti-smoking video, called the “Smoking Kid”, features children walking up to adult smokers asking for a light. The children in the ad are actors but the adults smoking are unsuspecting participants in the project.

The video begins with the statement “Adults know that smoking is harmful, but don’t remind themselves of this fact”. Once a “smoking kid” approaches the adults, every adult asked is shocked that the child with a cigarette in his hand is asking for a light. The first adult starts by saying “I’m not giving it to you” and the video goes on to state “every adult filmed said no and reminded the children that smoking is bad”.

Before going away, the kid hands each adult a booklet after being turned down for a light. The booklet says, “You worry about me, but why not about yourself?”Each adult looks around for the child as their faces are filled with confusion and discomfort.

The video shows that a few of the smokers quickly throw away their cigarettes or put their cigarettes away, showing that this experiment was effective at that moment.

The most influential element in the ad isn’t the use of children or the responses from the smoking adults. It comes down to something much simpler than that. Why is it that we worry about other people, forgetting to worry about ourselves?

   Everybody sleeps，but what people stay up late to catch or wake up early in order not to miss varies by culture.

From data collected，it seems the things that cause us to lose the most sleep，on average，are sporting events，time changes，and holidays.

Around the world，people change sleep patterns thanks to the start or end of daylight-saving time（夏令时间）. Russians，for example，began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to“winter time”starting on October 26.

Russia's other late nights and early mornings generally correspond（相一致）to public holidays. On New Year's Eve，Russians have the world's latest bedtime，hitting the hay at around 3:30 a. m.

Russians also get up an hour later on International Women's Day，the day for treating and celebrating female relatives.

Similarly，Americans' late nights，late mornings，and longest sleep fall on three-day weekends.

Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey（冰球）final.

The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it，and then they woke up earlier than usual the next morning thanks to summer nights，the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing，though，compared to Germans，Italians，and the French，who stayed up around an hour and a half later on various days throughout the summer to watch the World Cup.

It should be made clear that not everyone has a tool to record their sleep patterns；in some of these nations，it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case，the above findings are still striking. If the most health-conscious among us have such deep swings（明显改变）in our sleep levels throughout the year，how much sleep are the rest of us losing？

   Residents in the poorest counties in the U. S. face a life expectancy（预期寿命）up to a decade shorter than their counterparts in the wealthiest areas, according to a study published in the American Journal of Public Health.

Researchers from East Tennessee State University wanted to better understand how socioeconomic status was associated with health outcomes. To find it out they divided the country's 3,141 counties into 50 new states based on household income.

The researchers broke down the data by county since they found state-level data may hide some impact of socioeconomic differences on both the wealthiest and poorest counties. They then examined health data from the wealthiest and poorest states to see how residents differed on factors like smoking, clinical care and excessive drinking. Researchers found that there was nearly a 10-year gap in the life expectancy of men with an average of 79. 3 years in the wealthy counties compared to 69. 8 years in the poorest. For women,the difference was slightly less - 83 years in the wealthiest counties and 76 years in the poorest.

The researchers caution that while they found a connection between socioeconomic status and health outcomes, they did not analyze cause and effect. But they suggest that the data shows policymakers should not just focus on state-wide initiatives（计划）but more targeted efforts to help those most at risk. “With limited resources, methods of finding the poorest counties can assist in the allocation of resources and programs to those communities that are in the greatest need,”the researchers wrote.

The generation gap refers to the difference in opinions between the old and the young. It has some special determinants（决定因素），one of 【小题1】 is the choice of clothes. In many cases，old people don’t quite like the clothes young people wear. On the other hand，the youth argue that their clothes are fashionable，and dismiss（不接受）the ones【小题2】（wear）by their parents and grandparents.

Another obvious determinant is【小题3】 amount of technology used by different generations. Today，the younger generation use the【小题4】（new）technology. They believe they can achieve anything【小题5】 just clicking a buton. However，this view【小题6】（question）by the older generation saying the youth depend on technology too much to stand on their own feet.

The generation gap can be both good and bad. It’s good because it helps people experience and learn new things. However，it may turn out to be bad when one generation refuse to listen to the other generation or reject【小题7】 (they) ideas completely. This may result in bad and broken relationships. But，【小题8】 (fortunate)，overcoming their conflicts to bridge their generation gaps【小题9】（be）possible. The only thing people need【小题10】（do）is accept new things with an open heart.
