Article: Elderly women who eat foods higher in potassium are less likely to have strokes and die than women who eat less potassium-rich foods, according to new research in the American Heart Association. "Previous studies have shown that potassium consumption may lower blood pressure. But whether potassium intake could prevent stroke or death wasn't clear," said Smoller, professor of the department of population health at Albert Einstein College of Medicine, Bronx, NY. Researchers studied 90,137 women, aged from 50 to 79 for an average 11 years. They looked at how much potassium the women consumed, as well as if they had strokes, including ischemic strokes , or died during the study period. Women in the study were stroke-free at the start and their average dietary potassium intake was 2,611 mg/day. Results of this study are based on potassium from food, not supplements. The researchers found: Women who ate the most potassium were 12 percent less likely to suffer stroke in general and 16 percent less likely to suffer an ischemic stroke than women who ate the least. Women who ate the most potassium were 10 percent less likely to die than those who ate the least. Among women who did not have high blood pressure, those who ate the most potassium had a 27 percent lower ischemic stroke risk and 21 perc ent reduced risk for all stroke types, compared to women who ate the least potassium in their daily diets. Among women with high blood pressure, those who ate the most potassium had a lower risk of death, but potassium intake did not lower their stroke risk. "Our findings suggest that women need to eat more p otassium-rich foods. You won't find high potassium in junk food. Some foods rich in potassium include white and sweet potatoes, bananas and white beans." The U.S. Department of Agriculture recommends that women eat at least 4,700 mg of potassium daily. "Only 2.8 percent of women in our study met or went beyond this level. The World Health Organization's daily potassium recommendation for women is lower, at 3,510... Question: The benefits of potassium intake to elderly women do not include _ . - preventing strokes - reducing heart attacks - cutting down death risks - lowering blood pressure

Read the following article and select the best answer. Article: You may have heard the term "the American Dream". In 1848, James W. Marshall found gold in California and people began having golden dreams. That 19th century "American Dream" motivated the Gold Rush and gave California its nickname of the "Golden State". The American Dream drove not only 1800s gold-rush prospectors but also waves of immigrants throughout that century and the next. People from Europe, and a large number of Chinese, arrived in the US in the 19th century hoping that in America they would find gold in the streets. But most, instead, worked as railroad labourers. They created the oldest Chinatown, in San Francisco, and gave the city a Chinese name "the old gold hill". In the 20th century, some critics said that it was no longer possible to become prosperous through determination and hard work. Unfair education for students from poor families and racial discrimination almost made the American Dream a nightmare. Then, in the 1990s, California saw a new wave of dreamers in Silicon Valley. People poured their energy into the Internet. This new chapter of the American Dream attracted many business people and young talents from China and India to form start-ups and seek fortunes in America. Better pay, a nice house, and a rising standard of living will always be attractive. However, the new American Dream is no longer just about money. It encourages Americans to consume wisely to protect the environment, improve the quality of life, and promote social justice. The Governor of California, Arnold Schwarzenegger, has become the model of the new American Dream. After years of hard work, he grew from a poor young man from Austria into a movie superstar and then governor. Many people hope his story can save the American Dream and give California a brighter future. Question: Why did most of the early immigrants work as railroad laborers? - Because they could earn more money as railroad laborers. - Because they had to make a living by working as railroad laborers. - Because they thought railroad was the first step to find gold. - Because railroad laborers were greatly honored at that time.
Because they had to make a living by working as railroad laborers.

Article: It seemed like there were quarrels every evening.My children were always fighting over something.They never agreed on who had last washed the dishes,or who had last picked the,TV program.I was tired of constantly being a judge. One day,I thought over what my life was like before marriage.I recalled my high school days when the terms"Odd "day/and"Even"day meant something.My class schedule changed by turns between "O" days and"E"days.On O days I might attend Physics and Maths. And on E days I'd go to another elective class,such as First aid or Art. So I explained our new system to the children."Jolee,you were born first,"I said. "Is one an odd number or all even one?" "It's odd,Mom." "And A1,you arrived second.Is two odd or even?" "It's even,Mom." "Ok,so Jolee,from now on,every odd day is automatically your own special day.That means you get to pick what to watch,or which board game to play.Al,the same applies to you on even days." He thought about it a minute,then said,"But there are more odd days than even ones in some months.Jolee will get'her day'two times in a row when a month ends in 31,and the next one begins with a one." "True," I said,"but that also means she'11 be taking the smelly,disgusting rubbish out,washing the dishes,and doing other less-enjoyable things two more days in a row,and you won't.It's part of life's give-and-take." For the first few days after that,whenever one kid shouted,"Mom!"I'd just call out,"Whose day is it?"That settled it.Soon.the quarrelling ended. Ah,the complete joy of peace and quiet !
