【題目】閱讀下面短文，并按照題目要求用英語回答問題。
When I was growing up, I was embarrassed to be seen with my father. He was severely lame and very short, and when we would walk together, his hand on my arm for balance, people would stare. I would feel ashamed at the unwanted attention. If he ever noticed or was bothered, he never let on, nor did he say anything about it.
It was difficult to coordinate(協(xié)調(diào)) our steps—his pausing, my impatience—and because of that, we didn't say much as we went along. But as we started out, he always said, “You set the pace, I will try to adjust to you.”
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and despite bad weather. He almost never misseda day, and would make it to the office even if others could not. A matter of pride.
When snow or ice was on the ground, it was impossible for him to walk, even with help. At such times my sisters or I would pull him through the streets of Brooklyn, NY, on a child's sleigh to the subway entrance. Once there, he would grasp the handrail until he reached the lower steps that the warmer tunnel air kept ice-free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside until we met him in Brooklyn on his way home.
When I think of it now, I wondered at how much courage it must have taken for a grown man to subject himself to such indignity and stress. Andat how he did it—without bitterness or complaint.
He never talked about himself as an object of pity, nor did heshow any envy of the more fortunate or able. What he looked for in others was a“good heart”, and if he found one, the owner was good enough for him.
Now that I am older, I believe that is a proper standard by which to judge people, even though I still don't know precisely what a “good heart” is. But I know the times I don't have one myself.
My father has been gone many years now, but I think of him often. I wonder if he sensed my unwillingness to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy Iwas, how I regretted it. I think of him when I complain about incident, when I am envious of another's good fortune, when I don't have a “good heart”.
At such times I put my hand on his arm to regain my balance, and say, “You set the pace, I will try to adjust to you.”
（1）How did the man treat his father when he was young?
A.He helped his father happily.
B.He never helped his father.
C.He helped his father, but not very happily.
D.He only helped his father take a walk after supper.
（2）As a disabled man, his father ____.
A.didn't work very hard
B.didn't go to work from time to time
C.hated those who had good fortune
D.was happy and satisfied, and never lost hope
（3）What does the underlined word “reluctance” mean in the article? It means ____.
A.anger
B.sadness
C.happiness
D.unwillingness
（4）How did the father get to work usually?
A.By subway.
B.By bus.
C.By wheelchair.
D.By bike.

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 (醬類), 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 (鈉)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.
