     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

 There are various reasons why cancers appear to be on the increase. For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis (診斷), doctors can more easily recog??nize cancerous growths that would formerly have passed unnoticed or that would have been wrongly di??agnosed. It is also believed that certain habits and conditions of modem living, including heavy smok??ing and the pollution of the air, may leave people living in more cancer-causing conditions than before.

We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examina??tion of the blood.

Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.

The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.

The test examines very small bits of fat in the blood called lipids (脂質). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.

The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.

. Who will fail cancer from the study of the researchers?

A. The young.                           B. The middle age and the older.

C. The man.                               D. The woman.

The underlined words "such a test" refer to________.

A. the test that shows which persons have cancer and which don’t     .

B. the test that may be able to show cancer very early in its development,.

C. a simple medical test that cannot find cancer when it is -small

D. a new test that could be a step to develop a difficult way

. Which of the following statements is true according to the passage?

A. Cancers have much to do with something in patients’ blood.

B. People living in better conditions are most likely to be attacked by cancer.

C.X-raying is the best way to determined whether a person has cancer or not.

D. Cancers have nothing to do with a person’s habits and living conditions.

. What would be the best title for the passage?

A. A simple way to cancer                 B. Cancers can be cured

C. How to find cancer                    D. Early discovery of cancer
