I’m writing to tell you about discussion we recently had about if it is good or not for families to own cars.

As the development of people’s living conditions, more and more people have our own cars. Some of us think it’s good to own a car. Firstly, it’s a convenient, fast, and comfortable mean of transportation. Secondly, it shows that people are becoming richer, and the country much strong. It also makes relative businesses and industries to develop faster.

Others have different opinions. They think that cars give off waste gases and polluted the environment. Too many cars will have some bad effects, such as more accidents. Beside, the limited parking space is another big problem.

In my view, people should think careful before they buy a car.

Yours truly,

   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 new study shows that we spend more time using the mobile Internet to read newspapers and magazines or do some other things. According to the Interactive Advertising Bureau（IAB），the average European spends 4.8 hours reading newspapers and magazines but 1.6 hours more using the mobile Internet per week.

The IAB questioned 15,000 people in 15 European countries, looking at how people were using the Internet and its influence on their everyday lives. It found that the mobile Internet is increasingly finding its way into the public awareness. Over 71 million Europeans now have Internet access on their mobile phones. In the UK, 10 million people now access the Internet through their mobile phones and spend 6.3 hours doing so per week averagely.

Unsurprisingly, young generations in the UK are leading the way, with nearly half of the country's 16-to 24-year-olds and a quarter of 25-to 34-year-olds using the Internet, spending 6.5 and 6.2 hours online each week.

Entertainment plays a main role in our mobile Internet lives，with one in five British people using their phones for online games，a third listening to the online radio and 39 percent watching films，TV or other videos at least once a week. One third of those using an Internet phone said they received videos，images or other multimedia on their mobile，and 61percent said they passed on the contents they had received.

From a communication point of view，80 percent of those questioned agreed that the Internet had made it easier for them to stay in touch with friends and family.

Alison Fennah，director of the IAB，said the use of the mobile Internet had come to the point that marketers should be looking to strategies（策略）that connect them with consumers more effectively. "Better tools as well as improved consumer motivation that start coming together in 2011 can make a great difference to extending the online experience，" Fennah said.

Several countries in Asia celebrate the Lunar New Year in their own way. But dragon and lion dances in Chinatowns all over the world have helped to make China's New Year the most famous.
