Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，攝入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增強) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said， adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
61. According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious             B. it can‘t harm people’s health
C. it can lower cancer risk      D. it is not taken enough every day
62. Which of the following can not help people get more Vitamin D?
A. Have some sunshine        B. Have more meat
C. Have more fortified cheese   D. Have a vitamin supplement
63.Who can Garland probably be?
A. A health researcher        B. A doctor   
C. A scientist               D. A public health official
64.Which of the following food can lower people‘s chance of getting cancer?
A. Milk                    B. Fortified orange juice
C. Fortified yogurt           D. All of the above
65.People from which area should take more Vitamin D according to the passage?
A. Asian people               B. African people 
C. American people            D. European people

What’s delicious, healthy to eat and comes in various colors? Eggplant! And no, it has nothing to do with chickens! This strangely named vegetable is, however, as versatile as an egg. It can be steamed, fried or baked. It can be eaten by itself or combined with meats and other vegetables.

 Eggplant was first grown in India during the 5th century B.C. Its popularity soon spread to China and then throughout Asia. Finally, during the Middle Ages the vegetable made its way to Europe. At that time, eggplant was not the shiny purple vegetable most people know today. Instead, it was like a white egg. Due to this egg-like appearance, eggplant got its name. In its early days, the vegetable was so bitter that people often called it a “mad apple”. This nickname started because people believed its bitterness was bad for one’s health. People actually thought eggplant could cause insanity(精神錯亂) and cancer.

 Fortunately, today people know that eggplant doesn’t cause insanity or cancer. In fact, eggplant is so healthy that it may prevent cancer. In addition, the brain and the heart benefit from this supper vegetable. Since it is high in fiber, eggplant can also improve digestion.

 Italy, Turkey, Egypt, China and Japan are the leading growers of eggplant in the world today. Depending on its location, eggplant may be purple, green, orange or yellow-white. And it can be as small as a tomato or as large as a cucumber. Dish diversities(多樣性) range from simple to complex, with all of them being delicious!

Today, thousands of people are gathering in Loomis, Calif, for the 23rd annual Loomis Eggplant Festival. The main activity at the festival is eating delicious eggplant dishes. There is plenty more to do and see, though. Recipe contests, arts and crafts, performers, races and children’s activities all “egg-cite” festival-goers. Most people at the festival would agree — eggplant is an “egg-cellent” vegetable!

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷爾蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc．In general the person feels excited and ready to act.

Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger ferociously may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger.

1.The underlined word “ferociously” in Paragraph 2 probably means ______.

A．mildly            B．fiercely           C．frequently         D．hardly

A．Were you angry, you would get cancer.
