That“Monday morning feeling”could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.

　The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2, 600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day.

　Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.

　A study of 11, 000 Italians proved 8 a. m. on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewest heart attacks in both countries.

　The finding could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol（胆固醇）but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them, ”he said.

　Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.

　“When people get up, their blood pressure and heart rate go up and there are hormonal（内分泌）changes in their bodies, ”Willich explained. “All these things can have an unfavorable effect in the blood system and increase the risk of a clot（血凝块）which will cause a heart attack.”

　“When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activities,”said Willich.

I couldn’t believe my ears when I heard my name called for the leading role in our high school play. Mrs. Dermit, my drama(戏剧) teacher, had been looking for someone to play an energetic boy in a play. Luckily for me, she thought that I could act the   1 .

Money spent on advertising is money spent as well as any I know of. It selves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and so making it possible to provide for export at good prices. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more.
And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor article more than once. If you see an article frequently advertised, it is the proof I know that the article does what is promised for it, and that it has good value.
Advertising does more for the good of the public than any other force I can think of.
There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade.
If its message were nothing but information, that would be difficult to get more people to buy, for even a detail such as the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.

The oldest and most common source(来源) of renewaBle energy known to man, Biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of Biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----Biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide(二氧化碳), Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun’s energy. In this way, Biomass serves as a sort of natural Battery(电池) for storing the sun’s energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the “Battery” lasts forever.
According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008----although the numBers aren’t all in yet----wind power proBaBly took over first place Because of the rapid development of wind farms across the country.
Producing power from Biomass helps reduce some 11 million tons of carBon dioxide each year. Some homeowners also try to make their own heat By using Biomass materials. Such practice may save homeowner’s money, But it also produces a lot of pollution. So, the Best way is to encourage power plants to use it.
