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.
(1)According to the passage, the      can lower the risk of heart attack by 30%.

C."Oriental" diet
D.not mentioned
(2)The "Oriental" diet mainly includes the following foods EXCEPT      .

(3)If you want to avoid a heart attack, you should avoid       .
A.vegetables and fruits
B.tofu and soy
C.high sodium
D.the "Prudent" diet
(4)The underlined word "relationships" mentioned in the last but one paragraph refers to "      ".
A.study and diet
B.diet and heart attack
C.the Western diet and the "Oriental" diet
D.the United States and Europe

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.
(1)What is the passage intended to tell us?
A.Fruit should be frozen before one eats it.
B.Frozen food is better than hot food.
C.The author prefers frozen food.
D.Hot food is not healthy.
(2)The author began to enjoy frozen food when he _____________.
A.was young
B.learned cooking
C.got married
D.got a fever
(3)Why does the author NOT advise us to take hot cookies?
A.Because they need more time to prepare.
B.Because the taste is not good when they are hot.
C.Because they are too delicious to avoid our overeating.
D.Because we may eat them quickly and enjoy them less.
(4)What does the underlined word "it" in the third paragraph refer to?
A.The taste.
B.Buttercream.
C.The cookie.
D.Frozen buttercream frosting.

Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly.   But it can get worse and cause life-threatening symptoms (症状), such as bleeding and trouble breathing.
   
Ebola does not spread like colds or the flu because it does not float through the air. Ebola also doesn't spread through food or water, like some other viruses. Instead, Ebola spreads when someone touches the body fluids(液体) of a sick person.
   
An outbreak is when many people are getting sick with the same illness around the same time. You may have heard of a flu outbreak, which is when lots of people get sick from the same types of flu virus. When an outbreak happens because of a virus, more people could get sick because there is a lot of that virus around.
Where did Ebola come from?
Scientists aren't sure how the first person gets Ebola at the start.     Tropical animals in Africa believed to carry the virus include great apes, chimpanzees, gorillas, monkeys, fruit bats, porcupines, and forest antelopes.
What do kids need to do about Ebola?
Ebola is making many people sick in Africa, but no matter where you live, it's always a good idea to wash your hands well and often.    
A. What is an outbreak?
B. How do people catch Ebola?
C. Why do I need to wash my hands?
D. It's very important that infected people get treatment right away.
E. Ebola symptoms can start with fever and headache, kind of like the flu.
F. But they think that people may pick up the virus by touching or eating infected animals.
