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.

What did James Baker and John Hanan do about chocolate?
A:They produced the first milk chocolate.
B:They introduced chocolate to Europe.
C:They added sugar to make chocolate bars.
D:They made chocolate accessible to the average man.

The Beginning of American Literature



America has always been a land of beginnings.After Europeans"discovered"America in the fifteenth

century,the mysterious New World became for many people a genuine hope of a new life,an escape from

poverty and persecution,a chance to start again.We can say that,as a nation,America begins with that

hope.When,however,does American literature begin?

American literature begins with Amnerican experiences.Long before the first colonists arrived,before

Christopher Columbus，before the Northmen who"found"America about the year 1000,Native Americans

lived here. Each trilbe's literature was tightly woven into the fabric of daiiy life and reflected the unmistakably

American experience of lining with the land。Anoiher kind of experience,one filled with fear and excite-

ment,found its expression in the reports that Columbus and other explorers sent home in Spain,French and

English.In addition,the journals of the people who lived and died in the New England wilderness tell

unforgettable tales of hard and sometimes heartbreaking experiences of those early years.

Experience,then,is the key to early American literature.The New World provided a great variety of

experiences,and these experiences deniauded a wide variety of expressions by an even wider variety of early

American writers.These wnters included John Smith,who spent only two-and-a-half year on the American

continent.They included Jonathlan Edwards and William Byrd,who thought of themselves as British sub-

jects,never suspecting a revolution that would create a United States of America with a literature of its own.

American Indians,explorers,Puritan ministers,frontier wives,plantation owners一they are all the creators

of the first American literature.

What can we learn from the literature of the tribes of the native Americans?
A:About the everyday life of the native Americans.
B:About the arrival of Columbus.
C:About the experience of the first European settlers.
D:About the experience of those who died in the New England wilderness.

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.

The Arabic legend is used to prove that
A:.coffee was first discovered by Kaldi
B: coffee was first discovered by Kaldi's goats
C:.coffee was first discovered in south American countries
D: coffee drinks were first made by Arabs

Some Things We Know About Language
Many things about language are a mystery,and many will always remain so.But some things we do know.
First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood;indeed,the direct contrary has often been stated.Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense.There are,or were, hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.
A third thing we know about language is that all languages are perfectly adequate.That is,each one is a perfect means of expressing the culture of the people who speak the language. Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time. Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.

According to the third paragraph,the author thinks that______.
A:there exist some primitive languages in the world
B:there are many people who don't have a language
C:no languages in the world haven't been well developed
D:there are some languages we know having little complexities

资料：People differ greatly in their readiness to try new products. In each product area，there are“consumption pioneers”and early adopters. Other individuals adopt new products much later. After a slow start，an increasing number of people adopt the new product.
The five-adopter groups have different values. Innovators are venturesome-they try new ideas at risk. Early adopters are guided by respect-they are opinion leaders in their communities and adopt new ideas early but carefully. The early majority are deliberate-although they rarely are leaders，they adopt new ideas before the average person. The late majority skeptical-they adopt an innovation only after a majority of people have tried it. Finally，laggards are tradition bound-they are suspicious of changes and adopt the innovation only when it has become something of a tradition itself.

What is this excerpt about？

A.The consumption pioneers
B.How people adopt the new product
C.The five-adopter classification
D.The different phases of adopting new ideas

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.

First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood;indeed,the direct contrary has often been stated.Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense.There are,or were, hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.
A third thing we know about language is that all languages are perfectly adequate.That is,each one is a perfect means of expressing the culture of the people who speak the language. Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time. Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.

The author has used American Indian language to illustrate______.
A:it hasn't been well understood that there is no primitive language
B:the Indians communicated in a very primitive system of noises
C:English and Greek are less primitive than American Indian languages
D:hundreds of American Indian languages are easy and young
