Scientists Make Sweet Discovery
Good news for chocoholics:the treat preferred by millions all over the world is good for you,according
to American researchers at the University of California. Chocolate contains substances called flavonoids(类黄
酮)that can help maintain a healthy heart and good circulation.The researchers have discovered that cocoa
acts like aspirin and that eating a bar of chocolate once in a while may contribute to a healthy diet. Chocolate
has also been shown to release endorphins(内啡肽) in the body: these chemicals help to reduce pain and
stress and make you feel happy.
But who first discovered this wonderful way of keeping healthy?The Olmec Indians of Mexico and Central
America were the first to grow cocoa beans,in about 1500 BC,and the Mayas were drinking unsweetened
cocoa hundreds of years before it became fashionable in Europe.The word chocolate comes from the Nahuatl
word xocolati,which means"bitter water".
In 1544,a delegation of Mayan nobles visited Philip of Spain and gave him jars of cocoa as a gift. Cocoa
soon became fashionable in Spain and Portugal.The Spanish were the first to add sugar to their cocoa drink.
In the 17th century,chocolate was becoming fashionable with the middle-classes,not only as a drink but also
as a medicine.
By the middle of the century,solid chocolate was becoming familiar. In 1753,a Swedish scientist re-
named cocoa theobroma or" food for the gods".In 1765,James Baker and John Hanan opened the first choco-
late mill in the United States,introducing chocolate to the average citizen.In 1876,in Switzerland,Daniel
Peter had the idea of adding milk in the chocolate,making process and produced the first milk chocolate.
Since then,chocolate has grown enormously in popularity. One of the biggest chocolate-eating nations is
Britain where the average man,woman,and child eats nine kilos of chocolate a year!In fact,chocolate is the
number one comfort food and there are more"chocoholics"in Britain than anywhere else in the world.Re-
searchers warn that although chocolate is good for you,it should be eaten in small quantities and with no
added milk.

答案
B
解析
第一段第二句提到:巧克力中含有一种叫类黄酮的物质,它能维护心脏的健康并保持 血液循环畅通。 第三段第一句提到:1544年,一个玛雅贵族代表团勤见西班牙国王菲利普时送给他几 罐可可粉作为礼物。 第四段第二句提到:1765年,James Baker和John Hanan在美国开办了第一个巧克力作 坊,将巧克力介绍给了普通人。 短文最后一句提到:研究者劝告我们,虽然巧克力对我们有好处,但应该少量食用而且 不应另加奶。 从题目和总体内容可见,这篇短文说明了吃巧克力的好处,虽然后面提出吃巧克力时 的注意事项,但这不影响作者肯定的语气。
