Humans may have been enjoying cacao, which has been used to make chocolate, for much longer than experts had thought.

Researchers at the University of British Columbia in Canada have found that humans grew cacao trees and consumed (食用) cacao starting around 5,300 years ago.

The researchers found evidence of cacao’s use at an ancient village in the highlands of southeastern Ecuador. They examined the remains of very old objects. The village was part of the Mayo-Chinchipe culture of the Andes.

Scientists had already mostly agreed that cacao was first domesticated in South America instead of Central America, as they once believed. But the new discovery shows cacao was grown about 1,500 years earlier than was known before.

The University of British Columbia researchers also identified (证实) a substance found in the cacao tree but not in its wild relatives. This suggests that humans grew the tree for food purposes.

Today, the seeds are cooked and turned into many chocolate products.　 But thousands of years ago, cacao was used to make drinks.

Michael Blake is a professor of University of British Columbia who helped lead the study. He said that the objects on which cacao was found suggest a lot about how people used the substance at the time.

“They clearly drank it,” Blake told the Reuters news service.

There is no clear history of native populations in South or Central America using cacao to make chocolate the way people do now, the researchers reported. Native populations in the upper Amazon area today still use cacao to make special drinks, they added.

Evidence suggests cacao growing moved into Central America and Mexico about 4,000 years ago. It is not clear how cacao’s use spread between South and Central America.

But by the time Spanish explorers arrived in Central America in the late 1400s, people were using it to make hot and cold chocolate drinks with spices.

By the 1580s, Spain began importing cacao and spreading it to other European countries. By the 1800s, technology developed in the Netherlands made it possible to turn cacao into a solid chocolate product.

1.Where was cacao grown earliest?

A.Mexico. B.Canada

C.Central America. D.South America.

2.When it comes to the introduction of cacao to Europe, which country contributed most?

A.America. B.Canada.

C.Spain. D.Netherland.

3.Which of the following can serve as a best possible title for this passage?

A.The history of cacao. B.The home of cacao.

C.The use of cacao. D.The spreading or cacao.

高一英语单项填空困难题查看答案及解析

Do you have a spare room in your house? What about a driveway for your car? Both of these can help you make money.Many people who are feeling the pinch are taking advantage of what’s been called the “sharing economy”.

Perhaps the best-known example of a company in this field is Airbnb---an American web business which allows you to rent out your spare room to holidaymakers.It says it operates in 34,000 cities and it has over 1,500,000 listings.It seems to have concerned the market!

A British company is doing something with parking spaces.JustPark’s founder, Anthony Eskinazi, says ,“When I had the original idea,Ispotted a driveway close to a sports stadium.It would have been so convenient if I could have just parked in that driveway rather than in commercial car park.” And he has a big clientele（客户）:around 20,000 people have advertised their spaces on the site,and he says around half a million drivers use it.There are other sites doing very similar things,like Uber and Lyft---these let drivers share their cars with other passengers.Any driver knows how valuable a place to park is .A church near Kings Cross in central London has apparently made over £200,000 by renting out space in its yard to travelers!

Because this is a new business world,those rules aren’t there yet and many people are happy to share...as long as it pays!

But the sharing economy has its critics:the competitors of these new companies.People who run things like traditional B&B, commercial car parks and taxi services are afraid of ending up out of pocket.And there is another issue:regulations on these new business are unclear.How will renting out your driveway affect your neighbor?

1.What does the underlined phrase “feeling the pinch” probably mean?

A.Lacking in money B.Full of curiosity

C.Willing to help others D.Unsatisfied with their life

2.Who may be against the sharing economy?

A.A taxi driver who can’t find a a parking　 place B.A priest in the church near Kings Cross

C.A traveller who needs accomodiation D.A well-known high-end holiday hotel

3.Why are many people pleased to share according to paragraph 4?

A.They can gain huge profits B.They needn’t pay any fee

C.There are few rules to limit them D.The new business has no risks

4.Which of the following words can best describe the booming business?

A.Creative and developed B.Competitive but unpractical

C.Effective and worrying D.Traditional and acceptable

We do not know when man first began to use salt, but we do know that it has been used in many different ways throughout history. Historical evidence shows, for example, that people who lived over 3,000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve (保存) the dead.

Stealing salt was considered a major crime (罪行) during some periods of history. In the eighteenth century, for example, if a person was caught stealing salt, he could be put in prison and his ears could be cut off.

In the Roman Empire, one of the most important roads was the one that carried salt from the salt mines to Rome. Guards were stationed(安置) along the route to protect against salt thieves, and they received their pay in salt, thus bringing the English word, salary. Any guard who fell asleep while on duty was thought to be “not worth his salt”, and as a result he would get a little less salt on his next payday. The expression, “not worth his salt”, is still used today in English.

In the modern world salt has many uses beyond the dining table. It is used in making glass and airplane parts, in the growing of crops, and in the killing of weeds (杂草). It is also used to make water soft, to melt (融化) ice on roads and highways, to make soap, and to fix colors in cloth.

Salt can be got in various ways besides being taken from mines underground. Salt water from the ocean, salt water lakes or small seas can be used to make salt. Yet, no matter where it comes from, salt will continue to play an important role in the lives of people everywhere.

1.According to the text, salt can be used in the following EXCEPT _____.

A. keeping dead bodies

B. punishing thieves

C. protecting crops

D. making industrial products

2.In the Roman Empire many people were employed as guards to _____.

A. protect the city of Rome

B. watch people carrying salt

C. prevent thieves from stealing salt

D. carry salt from the mines to Rome

3.The expression “not worth his salt” used today refers to the one who _____.

A. fails to do his work well

B. should not be paid in salt

C. doesn’t want to work at all

D. should use less salt

4.The main purpose of the text is to tell readers _____.

A. how salt was found and got

B. salt is important in people’s life

C. salt was difficult to get in the past

D. what salt brings to the English language
