     New archaeological discovers suggest that trade between Europe and Asia along the Silk

Road probably began in some form many countries earlier than once thought. The findings, coupled with a widening range of scientific and historical research, could add a fascinating new

page to the epic of the Silk Road.

    The latest and most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.

    The official origin of East-West commerce along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission(使命)across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of Rome.

    But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.

The word “coupled” in the first paragraph could best be replaced by ______.

 A. produced       B. contributed      C. doubled        D. combined

The silk thread found in the hair of an Egyptian mummy suggests that ______.

 A. Egyptians had probably travelled to China to buy silk

 B. trade along the Silk Road began earlier than once thought

 C. historical research often achieves fascinating results

 D. new light can now be thrown on ancient trading practices

Until recently most historians believed that trade along the Silk Road _______.

 A. originated in the 2nd century BC

 B. extended human migration into eastern Asia

 C. began a million years ago

 D. primarily benefited the Egyptians

Historians have always considered Zhang Qian’s mission important because they believe ______.

 A. be brought back knowledge of Rome to the emperor     B. be discovered the Silk Road

 C. be helped establish East-West trade               D. be travelled as far as Afghanistan

Have you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠).It’s too bad that humans can’t hibernate.In fact, as a species, we almost did.

Apparently, at times in the past, peasants in France liked a semi-state of human hibernation.So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants.As soon as the weather turned cold people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end.

In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial(人造的) lighting and the electric bulb.

When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though.Now scientists are telling us our ancestors most likely slept in separate periods.The business of eight hours’ uninterrupted sleep is a modern invention.

In the past, without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight.The late night period was known as ”The Watch” It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbours .

According to some sleep researchers, a short period of insomnia(失眠) at midnight is not a disorder .It is normal.Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning.This period can be an extraordinarily creative time for some people.The impressive inventor, Thomas Edison, used this state to hit upon many of his new ideas.

Playing with your sleep rhythms can be adventurous, as anxiety may set in.Medical science doesn’t help much in this case.It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.

The example of the French peasants shows the fact that________.

 A.people might become lazy as a result of too much sleep

 B.there were signs of hibernation in human sleeping habits

C.people tended to sleep more peacefully in cold weather

D.winter was a season for people to sleep for months on end

The late night was called “The Watch” because it was a time for people_______.

 A.to set traps to catch animals        B.to wake up their family and neighbours

 C.to remind others of the time       D.to guard against possible dangers

What does the author advise people to do?

 A.Sleep in the way animals do.    B.Consult a doctor if they can’t sleep.

 C.Follow their natural sleep rhythm.D.Keep to the eight-hour sleep pattern.

What is the author’s purpose in writing the passage?

A.To give a prescription for insomnia.   

B.To urge people to sleep less.

C.To analyze the sleep pattern of modern people.  

D.To throw new light on human sleep.
