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（疼痛）. 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.

What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?
Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison an “Official Taste Tester” for the past 21 years. Testing helps manufacturers (制造商) to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream—as well as for developing over 75 flavors (口味).
Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No—there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this “cool” field.
In a typical morning on the job, Harrison tastes and assesses 60 ice cream samples. He lets the ice cream warm up to about 12℉. Harrison explains: “You get more flavor from warmer ice cream, which is why some kids like to stir (搅拌) it, creating ice-cream soup.”
While the ice cream warms up, Harrison looks over the samples and grades each one its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself, “Dose the product have the color expected from that flavor?” Next it’s time to taste!
Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy---working at one cool job.
1. What is John Harrison’s job?
A. An official. B. An ice-cream taster.
C. A chemist. D. An ice-cream manufacturer.
2.According to John Harrison, to be qualified（合格的） in the “cool field”, it is helpful to ________.
A. keep a diary of work
B. have a degree in related subjects
C. have new ideas every day
D. find out new flavor each day
3. What does Harrison do first when testing ice cream?
A. He stirs the ice cream.
B. He examines the color of the ice cream.
C. He tastes the flavor of the ice cream.
D. He lets the ice cream warm up.
4.Which of the following is probably the best title of the passage?
