Recently, a study (研究), published in BMC Medicine, found that sitting in front of the TV for a long time was a risk for people’s health.
After scientists used data (数据) on 370, 000 people, covering 12 years, they found about 9, 000 developed heart disease. They found people with genes (基因) of heart problems were more likely to develop heart disease. However, they found that people without such genes watching more than four hours of TV every day were also at the greatest risk of heart disease. People spending 2 to 3 hours a day watching TV had a 6% lower risk. And those who watched less than an hour had a 16% lower risk. The scientists of the research team finally found cutting TV watching time to less than an hour a day could prevent 10% of heart disease.
In life, people who want “one more episode (剧集)” might be the group at a higher risk, for they are easy to spend more time watching TV. If they have more snacks while watching TV, it might add the risk of putting their hearts in danger. So, if people want to watch TV longer, standing up and moving the body, or hanging out will work. But limiting their time on TV could be a more useful way to help them avoid possible heart problems in the future.

We can see many traffic signs on both sides (边) of the roads or streets. Some tell the drivers what to do, and others tell them what not to do. The traffic signs are the traffic rules. All the people must obey the rules.
Each traffic sign has its meaning (意思). Do you see the sign “p”? Do you know its meaning?
In big cities, there are a lot of cars and buses. They can’t stop on the street. If a driver wants to stop his car, he must find a place for his car－a car stop. For a driver, how does he find a car stop? The traffic sign “P” can help him. “P” is the first letter of the word “Park” and its meaning is “You can stop your car her!” After the driver finds the car stop, he can park his car there. And then he can do other things.
