Thursday, June 10,2004-A little black spot crawled across the bottom of the sun Tuesday, to the delight of stargazers(天文學家)around the world.

The spot was Venus, the second-closest planet to the sun and Earth's nearest neighbor. Venus hadn't passed between Earth and the sun in more than a hundred years.

From Egypt to Australia space fans wore special sunglasses to protect their eyes and prevent blindness while watching the six-hour event. In Preston, England, schoolchildren went wild when Venus appeared.

"They were literally jumping off the floor with excitement," said Gordon Bromage, an astrophysicist, or a scientist who studies objects in space, at Britain's University of Central Lancashire. "They were yelling, 'I've seen it. I've seen it!'"

In Cairo, Egypt, a group of students visited the ancient pyramids to view the planetary(行星的) passage.

"The pyramids are the perfect place to watch something so rare," said 15-year-old Wissam Adel Kamal.

The spectacular sight was only partially(部分地)visible in North and South America. Unlucky astronomy fans in Japan and Thailand couldn't see it at all, because of the lousy (糟糕的) weather.

"We could barely see the sun on and off through breaks in the clouds," said Maki Yanagisawa, who tried to watch in Hokkaido, Japan.

Venus passes so rarely before the sun because Venus and Earth orbit the sun at slightly different angles. For Venus to be visible on the face of the sun, it must pass exactly between Earth and the sun.

Still, if you missed the show, you may have another chance. Venus will travel back across the sun again in 2012. After that, it won't make the trip for another more than a hundred years.

3. If you miss the Venus show this time, you'll have to wait ________ to watch the next show.

A. 8 years B. more than 100 years

C. 15 years D. 2012 years

4. It was reported that ________ .
