The requirements for high school graduation have just changed in my community. As a result, all students must 1 sixty hours of service learning, 2 they will not receive a diploma. Service learning is academic learning that also helps the community. 3of service learning include cleaning up a polluted river, working in a soup kitchen, or tutoring a student.4a service experience, students must keep a journal and then write a5about what they have learned.
Supporters claim that there are many 6of service learning. Perhaps most importantly, students are forced to think 7their own interests and become8of the needs of others. Students are also able to learn reallife skills that 9 responsibility, problemsolving, and working as part of a team. 10 students can explore possible careers 11 service learning. For example, if a student wonders what teaching is like, he or she can choose to work in an elementary school classroom a few afternoons each month.
12 there are many benefits, opponents 13 problems with the new requirement. First, they 14 that the main reason students go to school is to learn core subjects and skills. Because service learning is timeconsuming, students spend 15 time studying the core subjects. Second, they believe that forcing students to work without 16 goes against the law. By requiring service, the school takes away an individual's freedom to choose.
In my view, service learning is a great way to 17 to the community, learn new skills, and explore different careers. 18, I don't believe you should force people to help others — the 19 to help must come from the heart. I think the best 20 is one that gives students choices: a student should be able to choose sixty hours of independent study or sixty hours of service. Choice encourages both freedom and responsibility and as young adults, we must learn to handle both wisely.
The fried foods, salty snacks and meat are major foods of the Western diet, which account for about 30 percent of heart attack risk across the world. Meanwhile, a diet rich in fruits and vegetables, the so called "Prudent" diet, can lower the risk of heart attack, according to a study.
The research which looked at dietary habits in 52 countries, found people who ate a Western diet had a 35 percent greater risk of having a heart attack, compared to those who ate little or no fried foods and meat. Those who followed a "Prudent" diet had a 30 percent lower risk of heart attack, compared to those who eat little fruits and vegetables.
The authors also looked at an "Oriental" diet, rich in tofu, soy and other sauces (酱类), and found it did not increase or decrease the risk of a heart attack.
Previous studies have reached similar conclusions about the "Prudent" and Western diet in the United States and Europe, but did not include the Oriental pattern of eating. While some food of the Oriental diet may protect against heart trouble, the higher sodium (钠)content of sauces counter(抵消) that benefit.
"This study indicates that the same relationships that are observed in Western countries exist in different regions of the world, "a professor of medicine at McMaster University said.
Canadian researchers analyzed risk factors in food choices and the risk of heart attack in about 16, 000 people in 52 countries. Almost 6, 000 people had heart attacks, while the rest had no heart disease.
Some people love eating food right after it is cooked. I prefer food just taken out from the freezer. Fruit, candies, nuts, chocolate, cake with buttercream frosting(糖霜), even peas, all of them taste delicious when frozen. In fact, I often eat them that way.
I was a kid when I picked up the habit. In my family, lots of things were thrown into the freezer — finally, two freezers — to prevent them from going bad. Among them were some of the candies my sisters and I had collected on Halloween.
If we eat when they are still warm, we'll find ourselves taking the cookies more than we should. It's better if we can put them into the freezer and wait. That way we'll eat less and enjoy them more because they are hard and chewing becomes a slower, more patient effort. That's the point about frozen buttercream frosting. Put it in your mouth at room temperature, and it's gone very quickly. But when it's frozen, you can enjoy the taste much longer as it melts(融化) in your mouth.
The freezer treats a lot of fruit kindly. Take frozen grapes for example, I keep a bowl of grapes in my freezer. They become a little icy, and somehow their sweetness is improved. They are perfect and healthy dessert(点心). This is the same with oranges, apples, bananas…You might think bananas would get superhard when frozen. Wrong! They become cool, creamy and sweet. If you have wisely covered some or all of the bananas with melted chocolate before putting them into the freeze, they will have a double taste.
As long as you aren't eating anything that truly has to be hot, go ahead and experiment.
