WASHINGTON, March 13—When 17-year-old Mary Masterman set out to build a spectrograph（摄谱仪）, she knew it would be no easy task. The device, an instrument used to identify characteristics of different kinds of molecules, can cost thousands of dollars, and Mary was building on a budget. “I wanted to build one that was lower costing so it would be more available to anyone interested in spectrography（摄谱术）,” Mary said.

A senior at Westmoore High School in Oklahoma City, Mary built the spectrograph at home for $300, and her project won the top prize of a $100,000 scholarship in the Intel Science Talent Search Monday night in Washington. “The most challenging part was trying to get it to work,” said Mary, who said she hoped to attend Stanford or the Massachusetts Institute of Technology.

“I had to keep coming up with creative ways to adjust or change something,” she said．“It took three months to build and another three months before it actually functioned properly.” Mary said she chose to build a spectrograph because of its many applications in forensics（法医检查）, medicine and artwork analysis.

Some 1,700 students entered this year’s contest, and 40 finalists were chosen, all of whom won a laptop computer and a cash prize. The finalists were almost equally divided by sex. Six women were among the top 10．The second-place winner was John Pardon, 17, of Chapel Hill, N.C., who researched the unfolding of simple closed curves. He won a $75,000 scholarship. Dmitry Vaintrob, 18, from South Eugene High School in Eugene, Ore., won the third-place, a $50,000 scholarship, for a mathematics project exploring loop homology.

New York produced 12 finalists, more than any other state. Two New Yorkers placed in the top 10．Elizabeth Marincola, president of Science Service, the nonprofit group that administers the contest, said winners had a certain “spark”. “They have a deep passion for their research,” Ms. Marincola said.

1．What is the best title of the passage? (Please answer within 10 words.)

2．Which sentence in the passage can be replaced by the following one?

Altogether Mary spent 6 months to build a cheap spectrograph which could work with real functions.

3．What was the final result of the contest? And what conclusion can we draw from the contest result? (Please answer within 30 words.)

4．Translate the underlined sentence in the fourth paragraph into Chinese.

第三部分：阅读理解（共20小题；每小题2分，满分40分）

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

WASHINGTON（AP）—Good news for dinosaur fans：There are probably a lot more of them waiting to be discovered．At least，their fossils are．

Peter Dodson of the University of Pennsylvania and Steve Wang of Swarthmore College estimate that 71 percent of all dinosaur genera（种类）—groups of dinosaur species—have yet to be discovered．

“It’s a safe bet that a child born today could expect a very fruitful career in dinosaur paleontology（古生物学），”Dodson said in a statement．

The estimate appears in Tuesday’s issue of Proceedings of the National Academy of Sciences．

Dodson—a professor of anatomy at Penn’s School of Veterinary Medicine and professor at Penn’s Department of Earth and Environmental Sciences—first estimated the potential number of dinosaur genera in 1990 and is revising that upward．

The estimates are based on the rates of discovery—about 10 to 20 annually—and the recent increase in finds of fossils in China，Mongolia and South America．

Dodson suggests that 1,850 genera will eventually be discovered．So far 527 genera have been found．

Fossilization itself is a rare event，they note，and as many as half of the dinosaur genera that ever existed may have left no remains．

“I would never suggest that this prediction．however statistically（统计上地）sound．is the final word on dinosaur diversity，“Dodson added．”My intention is to fuel the discussion using the facts at hand，and this is the best estimate we can make with the data available．”

56．The best title for the passage would be______________．

A．Much more dinosaur once lived on the earth

B．Good news for dinosaur fans

C．A very fruitful career in dinosaur paleontology

D．Dinosaurs remain to be discovered

57．Who made the first estimate about the possible number of dinosaur genera?

A．The author of the passage．           B．Steve Wang．

A．The number of dinosaur fans is getting larger and larger．

B．More dinosaur fossils are expected to be found in future．

C．The estimate was based on plenty of facts of dinosaur paleontology．

D．Not all the dinosaur genera left their fossils．

59．It can be inferred from the text that______________．

A．dinosaurs will return to the world once again

B．about 3700 dinosaur genera once lived on the earth

C．only half of the dinosaur fossils have been found so far
