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

A. Venus was a little black spot
B. Venus show takes place every a hundred years

B. The sky must be very clear.
C. Special sunglasses must be used.
D. Earth must travel in front of Venus.
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 ________ .

查看习题详情和答案>>Modern man has cleared the forests for farmland and for wood,and has also carelessly burned them. More than that,though,he has also interfered (干涉) with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau (凯亚巴布高原) of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of largesized pine,Douglas fir,white fir,blue and Engelmann spruce. In 1882 a visitor noted,"We,who ... have wandered through its forests and parks,have come to regard it as the most enchanting region it has ever been our privilege (特权) to visit."This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions,timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then,in 1906,President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time,6,250 mountain lions,wolves and bobcats were killed. Before the program,there were about 4,000 deer in the Kaibab,by 1924,there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd (鹿群),but a far greater loss resulted from starvation (饥饿) and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.
The destruction of the environment of the Kaibab resulted from .
A.turning the forest into cultivated land
B.interfering with natural cycle of forest life
C.forest fires caused by man’s carelessness
D.cutting the trees for building materials
"Engelmann spruce"(Para. 2) is most likely the name of .
A.a tree B.an animal C.a mountain D.a game
The number of the deer in the Kaibab had increased enormously in years’ time.
A.25 B.6 C.18 D.12
Years later,large numbers of deer in the Kaibab died mainly because of .
A.the cold B.the organized kill
C.the shortage of food D.the poor management

The United States is one of the few countries in the world that has an official day on which fathers are honored by their children.On the third Sunday in June, fathers all across the United States are given presents, treated to dinner or otherwise made to feel special.
However, the idea for creating a day for children to honor their fathers began in Spokane, Washington.A woman by the name of Sonora Smart Dodd thought of the idea for Father’s Day while listening to a Mother’s Day sermon(布道)in 1909.Having been raised by her father, Henry Jackson Smart, after her mother died, Sonora wanted her father to know how special he was to her.It was her father that made all the parental sacrifices and was, in the eyes of his daughter, a selfless and loving man.Sonora’s father was born in June, so she chose to hold the first Father’s Day celebration in Spokane, Washington on the 19th of June, 1910.
In 1924 President Calvin Coolidge declared the third Sunday in June as Father’s Day.Roses are the Father’s Day flowers: red to be worn for a living father and white if the father has died.
When children can’t visit their fathers or take them out to dinner, they send a greeting card.Traditionally, fathers prefer greeting cards that are not too sentimental(感伤的).Most greeting cards are too special so fathers laugh when they open them.Some give heartfelt thanks for being there whenever the child needed Dad.
