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 cause heart attack or stroke(中风) within as little as a few hours after exposure. In one report 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. Another 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.

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don‘t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources, we are short of others, for example, fresh water. It is reported that we will have no coal or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

Men who wear pink shirts to work earn more and are easier to get a higher position than those who prefer traditional shirt colors, such as white and blue, according to a recent survey. Researchers also found that men who wore pink were more likely to get praise from female co-workers and were more confident in the office.

A classical pink shirt wearer earns £1,000 more a year than those who choose other colors, researchers surveyed among 1,500 male office workers. Men who wear pink are also twice as likely to have the Master’s degree as those who prefer white shirts, with one in ten pink shirt wearers having a PHD.

Stephanie Thiers-Ratcliffe, International Marketing Manager for Cotton USA, who took charge of the study, said, “You can tell a lot about someone by the color he wears. Pink is a color that more and more men have been embracing recently, and it is encouraging that they are not afraid to experiment with that bright color. They spend most of their days at work and their own confidence needs to remain smart. It is good for company standards, but that doesn’t mean that they have to wear boring clothes.” Pink shirt wearers on the other hand are more likely to have a low-carbon (低碳的) life for half of them prefer to choose public means of transportation to go to work.

The report also found men who preferred green shirts were the most likely to be late for work, while white shirt fans were the most punctual (准时的).
