Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't 1 it to be blue - the name has nothing to 2 the color of our closest celestial（天体） neighbor.
A full moon 3 on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the 4 moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be 5 in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up 6 New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when 7 of the moon enters the Earth's shadow. The 8 will not be visible in the Americas.
A full moon occurs 9 29.5 days, and most years have 12. 10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The 11 time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't 12 again until 2028.
Blue moons have no astronomical 13 , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a 14 in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon 15 after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar 16 a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the 17 decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a 18 moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay 19 on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm 20 celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

查看习题详情和答案>>of as being a chicken.
However, one tiger, which lives in an English zoo, turned out to be more cowardly than his keepers could
ever have imagined.
Tanvir, a two-year-old Bengal tiger, got stuck at the top of a new 5m-high activity tower in his enclosure,
after climbing it for the first time.
The branching tower had been designed to provide mental stimulation for Tanvir by testing his ingenuity,
but after scaling the exercise structure in just a few seconds, he lost his nerve when it came to coming back
down.
Tanvir went on to spend nearly two days at the top of the tower trying to pluck up the courage to attempt
a descent.
A spokesperson for the zoo said chat Tanvir had taken half an hour to come down from a smaller structure
only l.5m high previously, and that the taller tower had clearly been too much for him.
"Every time he gets to the edge, he looks out, puts a paw over, and thinks, 'no, I'm not doing it!'" said
Samantha Cordrey.
In the end Tanvir's hunger got the better of his fear, and after almost 48 hours he made his way down in
order to eat.
It appears that Tanvir is none the worse for his experience, but it is not known if he will find the guts (勇
气) to go back up his exercise tower again.
The whole episode only serves to underline the difficulties faced by zoo staff in creating environments that
will stimulate the animals living in enclosed spaces.
"It was made to challenge him but he's a bit of a wimp," said Tanvir's keeper.
B. tigers have nothing to do with chickens
C. tigers sometimes feed on chickens
D. tigers are generally not so cowardly
B. The first tower did not have any effect in training the tiger.
C. It is uncertain whether Tanvir will go back up the tower once more.
D. Tanvir enjoyed his stay on the tower so much that he refused to come down.
B. To call on us to protect tigers that are being kept in enclosed spaces.
C. To emphasize the difficulties of creating suitable environments for enclosed animals.
D. To tell readers how to train wild animals, such as tigers.
B. Zoo keepers knew the structure was a bit difficult for Tanvir.
C. Tanvir was the only tiger that was trained by the zoo keepers.
D. All tigers needed training before they were set free from the zoo.
