1、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people ｏｒsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit fｏｒsingles ｏｒunhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study authｏｒJulianne Holt Lunstad, a psychologist who specializes in relationships ａｎｄ　health, said in a prepared statement.The study included 204 married ａｎｄ　99 single adults who wore portable blood - pressure monitors fｏｒ24 hours. The monitors recorded blood pressure at random intervals ａｎｄ　provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one ｏｒtwo readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points ____ on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married ａｎｄ　single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet ａｎｄ　having regular doctｏｒvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】

2、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame ａｎｄ　the same ｏｒworse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile ａｎｄ　into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic fｏｒthe Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " According to Krom, Egypt\'s Old Kingdom fell ____.【单选题】
