D Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways: A happier heart Scientists at Harvard University recently examined 136 studies on cocoa — the main ingredient in chocolate — and found that it does seem to strengthen the heart. Studies have shown increased blood flow is good for heart. These are the results of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症). Better blood pressure If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly. Muscle magic Chocolate milk may help you recover after a hard workout (锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks. Better for your skin German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister (滑润的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance. Brain gains It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving skills by increasing blood flow to the brain. 73.

New research has determined that the ability to quantify may develop much sooner than most parents realize. Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants(婴儿)are able to quantify substances(物质)—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food. With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount. “Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” vanMarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.” This information further refutes(驳斥)the long-held idea that babies “know nothing of the world,” vanMarle said. “Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” vanMarle said. In the future, vanMarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study. 60.

Unique Quantifying Methods C Even before my father left us, my mother had to go back to work to support our family.Once I came out of the kitchen, complaining, “Mom, I can't peel potatoes.I have only one hand.” Mom never looked up from sewing."You get yourself into that kitchen and peel those potatoes," she told me. “And don't ever use that as an excuse for anything again!” In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel bar to the next.When it was my turn, I shook my head.Some kids behind me laughed, and I went home crying. That night I told Mom about it.She hugged me, and I saw her "we'll see about that" look. The next afternoon, she took me back to school.At the deserted playground, Mom looked carefully at the bars. "Now, pull up with your right arm," she advised.She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other arm.Day after day we practiced, and she praised me for every rung (横档) I reached.I'd never forget the next time, crossing the rungs.I looked down at the kids who were standing with their mouths open. One night, after a dance at my new junior high, I lay in bed sobbing.I could hear Mom come into my room."Mom," I said, weeping, "none of the girls would dance with me." (责任编辑：admin) |
