Ⅲ.阅读理解
A
About seven years ago, whenever I notice someone looked nice, I started telling them they looked nice. Shortly afterwards, I came up with an observation: If you tell five people during the day that they look nice, at the end of the day, six people feel great. Here are some fruitful experiences I have with this.
One day, I was riding with a friend when we rolled to a stop at the traffic light. As we waited for the light to turn green, a man walked across the crosswalk. He looked very together, so I called out, “Hey, you look sharp today！” Pointing towards a building, he said, “Thanks, but I was sharper there.” His comment puzzled me. But before I could ask about it, the light turned green, and we drove on. I asked my friend what he meant. My friend informed me that we were at the corner of a radio station and the man was the voice on the radio. Then I understood. But no matter who he was the biggest thing for me was that he was smiling when he accepted my compliment (赞扬)．
Later that day, there was a woman standing on the corner where we were turning, and I yelled (大喊) the compliment again, “You look nice！” She was just taking a sip of a bottle of water and started to laugh. I felt good to get a laugh.
Another day, while seated in a restaurant, there was a lady sitting near me. I really did not care for her skirt, but she did look nice in it, so I told her, “You look nice today.” She looked at me and rolled her eyes a little. Well, her friend sitting next to her told her, “He just gave you a compliment. Say thank you.” I don't remember whether she said “thank you” or not, but what I did notice was that her friend was smiling at my “You look nice today” compliment.
1. The underlined word “sharp” in Paragraph 2 probably means ________.
A. attractive B. sudden
C. strict D. mild
答案与解析　A　从其次段，尤其是其次段最终一句可知，作者赞扬了那个人。sharp的意思和attractive“有吸引力的；吸引人的”最接近。
2．Which of the following statements is NOT true according to the passage?
A. The first man the author praised accepted his compliment.
B. The first man the author praised worked at a radio station.
C. The woman standing on the corner didn't like the compliment.
D. The friend of the lady in the restaurant felt happy about the compliment.
答案与解析　C　C项不合文章主旨，“站在拐角的那位女士不宠爱这个赞美”。
3．What would be the best title of the passage?
A. Fruitful Experiences
B. Help Others, Help Yourself
C. Learn to compliment
D. “You Look Nice Today”
答案与解析　D　本文表明作者对赞美别人这一行为的生疏，D项在文中反复消灭，故选择D项。
B
The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child's stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores (苦痛). The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches (淀粉)instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.
The unbelievable thing about kwashiorkor is that the very existence of the disease — which has been killing thousands of children for centuries—was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO's work in Africa that led to the discovery of the problem in Central America.
4．From the passage we learn that kwashiorkor is a disease caused by ________.
A. poor living conditions B. lack of proteins in food
C. breastfeeding D. lack of food
答案与解析　B　从其次段的句子：“The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches (淀粉) instead of greatly needed proteins.”可知kwashiorkor这种病是由于食品中缺乏蛋白质造成的，选择B项。
5．It is difficult to discover kwashiorkor because ________.
A. it has no symptoms at all
B. it is hard to identify signs of it
C. it doesn't last long enough for careful observation
D. it is hardly different from other diseases
答案与解析　D　从第一段的句子：“They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor.”可知kwashiorkor很难被发觉由于他的症状和其他的病没什么不同，选择D项。
6．What is mentioned as a simple but reasonable way of curing this disease?
A. Taking a special medicine.
B. Avoiding any food containing starch.
C. Having more meat or milk.
D. Taking medicine full of proteins.
答案与解析　C　从其次段的句子：“They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.”可知治疗这个病的简洁的方法是在食物中增加更多的肉和牛奶。选择C项。
7．What's the best title for the article?
A. Milk and Meat Are Daily Necessities
B. Kwashiorkor and Improper Eating Habits
C. A New Form of Illness in Africa and Latin America
D. A Case of Eating Habits
答案与解析　B　这篇文章讲的是由于饮食不适当引起kwashiorkor的疾病，所以Kwashiorkor and Improper Eating Habits是最恰当的标题，选择B项。
