题目内容
When most of us hear the word chocolate, the verb that comes to mind is probably “eat”, not “drink”, and the most proper adjective would seem to be “sweet”. But for about 90 percent of chocolate’s long history, it was strictly a beverage (饮料), and sugar didn’t have anything to do with it.
The Origin of Chocolate
Many modern historians have estimated that chocolate has been around for about 2000 years, but recent research suggests that it may be even older.
In the book The True History of Chocolate, authors Sophie and Michael Coe prove that the earliest linguistic (语言学的) evidence of chocolate consumption dates back three or even four thousand years.
Valuable and Fashionable Chocolate Beverage
It’s hard to discover exactly when chocolate was born, but it’s clear that it was cherished from the start. For several centuries in pre-modern Latin America, cacao beans were considered valuable enough to use as currency. 100 beans could purchase a good turkey hen, according to a 16th-century Aztec document.
Sweetened chocolate didn’t appear until Europeans discovered the Americas and sampled (品尝) the native cuisine. Chocolate didn’t suit the foreigners’ taste at first — one described it in his writings as “a bitter drink for pigs” — but once mixed with honey or cane sugar, it quickly became popular throughout Spain. By the 17th century, chocolate was a fashionable drink throughout Europe, believed to have nutritious, medicinal functions. But it remained largely a privilege of the rich until the invention of the steam engine made mass production possible in the late 1700s.
The Birth of Solid Chocolate
In 1828, a Dutch chemist found a way to make powdered chocolate. His product became known as “Dutch cocoa”, and it soon led to the creation of solid chocolate. In 1847, Joseph Fry created the first modern chocolate bar. By 1868, a little company called Cadbury was marketing boxes of chocolate candies in England. Milk chocolate hit the market a few years later.
Prosperous Chocolate Industry
In America, chocolate was so valued during the Revolutionary War that it was used instead of wages. Even now, statistics show that the humble cacao bean is still a powerful economic force. Chocolate manufacturing is a more than 4-billion-dollar industry in the United States, and the average American eats at least half a pound of the stuff per month.
1.The earliest chocolate was most probably _________.
A. a dish B. a drink C. a bar D. a candy
2. It can be inferred from the passage that ________________.
A. the history of chocolate is at most 4,000 years.

A. Because chocolate was so tasty and bitter.
B. Because chocolate was believed to be a source of nutrition.
C. Because chocolate was sweetened with honey or cane sugar.
D. Because chocolate became a fashionable beverage.
4.Which one shows the correct order according to the time of their appearing? _________
A. chocolate beverage----chocolate bar----chocolate candies----milk chocolate
B. chocolate bar----chocolate beverage----chocolate candies----milk chocolate
C. chocolate bar ----chocolate candies ----milk chocolate ---- chocolate beverage

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有机燃料) when they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”

Parents whose children show a special interest in a sport feel very difficult to make a decision about their children’s careers.Should they allow their children to train to become top sports men or women? For many children it means starting schoolwork very young, and going out with friends and other interests have to take a second place.It’s very difficult to explain to a young child why he or she has to train five hours a day, even at the weekend, when most of his or her friends are playing.
Another problem is of course money.In many countries money for training is available from government for the best young sportsmen and sportswomen.If this help can not be given, it means that it is the parents who have to find the time and the money to support their child’s development and sports clothes, transport to competitions, special equipment, etc.All can be expensive.
Many parents are worried that it is dangerous to start serious training in a sport at an early age.Some doctors agree that young muscles may be damaged by training before they are properly developed.Professional trainers, however, believe that it is only by training young when young that you can reach the top as a successful sports person.It is clear that very few people do reach the top, and both parents and children should be prepared for failure even after many years of training.

A.An advertisement. | B.A diary. |
C.A newspaper. | D.A notice board. |
A.To become less important. |
B.To put it at another place. |
