听力原文： Leonardo da Vinci was born in 1452 in Taskani. As early as 1466, he was working in a workshop. Then, in 1482, he moved to Milan. After the plague had swept the city in Milan in 1484-85, he turned his attention to town planning and made several designs for churches and other buildings. He moved to Florence, another city in Italy in 1500, where he painted the famous Mona Lisa in 1503. Then, he returned to Milan between 1510 and 1515 after he had been working as an architect and engineer for the French king Louie XII. He devoted himself to painting again and produced three great works, "sin to end", "Mary and Child" and "Saint John the Baptist". In 1515, the king of France invited Leonardo to live in France. He moved to a castle there, where he spent his last years carrying out his own research. He died in 1519.

Two years ago this month, Doubleday published a historical thriller with an announced first printing of 85,000 and high hopes that a little-known writer named Dan Brown would catch on with the general public. "We surely expected to have a huge success, but I don't think anyone dreamed it would become a historic publication," says Stephen Rubin, president and publisher of the Doubleday Broadway Publishing Group.
(41)______.
If the "Harry Potter" books stand as the essential popular read for young people, then "The Da Vinci Code" has captured the crown for grown-ups. A word-of-mouth sensation from the moment it came out, Brown's controversial mix of storytelling and speculation remains high on best-seller lists even as it begins its third year since publication.
(42)______.
Twenty-five million books, in 44 languages, are in print worldwide and no end is in sight. Booksellers expect "The Da Vinci Code" to remain a best-seller well into 2005. A planned film version by Oscar-winning director Ron Howard should bring in even more readers. And at a time when consumers are supposedly minding their budgets, sales for the $24.95 hardcover have been so good that Doubleday still has set no date for a paperback.
(43)______.
"It's been our No. 1 fiction book for two years in a row, and I can't remember another time that happened," said Bob Wietrak, vice president of merchandising for Barnes & Noble Inc. "People come into our store all the time and ask for it or ask for books that are like it."
(44)______.
Thanks to "The Da Vinci Code", about the only books that seem able to keep up are Brown's previous novels. "Deception Point," first released in 2001, now has 3.7 million copies in print, according to Simon & Schuster, Brown's previous publisher. "Angels and demons," published in 2000 and featuring "Da Vinci" protagonist Robert Langdon, has more than 8 million copies in print.
(45)______.
The unprecedented success of "The Da Vinci Code" has been helped by wide access, with the book on sale everywhere from Wal-Mart to airports to supermarkets, often proving more popular than the mass market paperbacks available at the same outlets.
"The Da Vinci Code" has also thrived during a time when both literary and commercial novels struggled, when a tight economy, competition from other media and election year tensions drove the public to nonfiction works or away from books altogether. Publishers and booksellers say Brown's novel has worked by combining narrative excitement and provocative—and disputed-historical detail.
Section B

Section B
Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文： Human beings enjoy challenges. Many of them like physical challenges. They ask themselves questions like these: How fast can I run？How high can I climb？How deep can I dive？How far can I swim？How long can I hold my breath？How much can I lift？How high can I jump？Because people enjoy challenges，they like to play sports and watch other people play sports. They like climbing，running，diving，lifting，jumping，and so on. Every four years，millions of people all over the world enjoy the international sports competition called the Olympics.
There are challenges that，are not physical challenges. There are social and intellectual challenges，too. Leonardo Da Vinci，who lived in Italy during the fifteenth century，enjoyed every possible challenge. He was an artist and painted the well-known picture，the Mona Lisa. He was an engineer who made plans for a city with roads under the street for traffic. He was an inventor who invented a device to let people breathe under water. He was a scientist，and he learned a great deal about human structure.
Another kind of challenge faced the Egyptians between 4，000 and 5，000 years ago when they decided to build the first pyramid. They used six million tons of rock. That is enough to build a ten foot wall around all of France. Four hundred thousand men worked for twenty years to build it.
So，for thousands of years，people accepted challenges. Today we still have many challenges before us. Medical science faces the challenges of conquering the many diseases which still attack human beings. Engineers and planners must build new cities and new kinds of transportation. Scientists must develop new forms of energy. And many of us are interested in the challenge of space. We live in an age of challenge.
(27)
A．Social challenge.
B．Physical challenge.
C．Economic challenge.
D．Intellectual challenge.
