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."

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.

The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?

During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.?

In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.?

At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?

If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?

No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(症状).?

1. The writer offered _______ examples to support his argument.?

A. 4 B. 5 C. 6 D. 3

2. Which of the following does not agree with the chosen passage??

A. The Eskimos do not suffer from colds all the time.?

B. Colds are not caused by cold.?

C. People suffer from colds just because they like to stay indoors.?

D. A person may catch a cold by touching someone who already had one.

3. Arctic explorers may catch colds when ________.

A. they are working in the isolated Arctic regions?

B. they are writing reports in terribly cold weather?

C. they are free from work in the isolated Arctic regions?

D. they are coming into touch again with the outside world

4. The passage mainly discusses ________.

A. the experiments on the common cold

B. the fallacy about the common cold?

C. the reason and the way people catch colds

D. the continued spread of common colds

Her frozen fingers touched the flame trying to feel alive. She could feel the warmth but it was a cold heat, as if the candle was rejecting her.

Her arms turned red because of the cold, her short sleeved shirt not giving her enough warmth. The winter air grabbed(抓住) at her arms, causing her pain, but she didn’t mind. She knew she should put her jacket on, it was winter in Connecticut, but that would be giving up. Up here, in this tree she felt safe.

She looked at the candle, surrounded by hardening wax(蜡). She placed her fingers gently on the warm green wax. This candle was a reminder of her life inside that house, a life she would have to return to eventually.

As a child, she had gotten this candle. She spent all she had on it. The beautiful crystal box （水晶盒）had caught her eye. Five whole nickels（五分币） had brought her that candle.

She gave it to her mother for Mother’s Day. Her mother had managed a smile and put it on a shelf. “It’s very pretty, honey! I will put it right here.” Since then that candle had never been moved, never been lighted, sitting dusty on a cluttered shelf that no one could see. Later on, her parents got divorced.

By now the candle was colder than the air and the darkness was complete. The snow on the ground made the night lighter and less satisfying than it had been before the first snowfall. She liked the darkness because she felt safe in it. From the glances of her friends who liked the girl she used to be. From the boys who could never figure out who she was. From her guidance counselor(顾问) whose endless worried looks never made her feel any better.

No one was outside at this time of night. She was alone in the world, just how she liked it. Just as she was about to lean back against the branch, she heard a sound.

She heard footsteps breaking the ice in the snow, heading toward her. He was making his way toward the white fence at the edge of the building, right against the road. Normally she would have ignored this person and stayed on her branch faraway from human contact, but this figure had something with him. He trudged(吃力地走) toward the white fence carrying a case. The figure reached the fence, opened the case and took out a shiny object.

She took her eyes off this figure only long enough to climb down the tree to get a better view of him. She reached the bottom and saw that the person had turned to face the street, sitting on the white fence that she and her friends once sat on. She stepped carefully on the ice, making her way toward him.

And then a beautiful sound of music came from the shiny object. She stopped and listened to it. She started walking towards the guy again. Just as she was about to step onto the snow banks, she slipped on the ice crashing to the ground. The figure turned around in surprise and a sudden recognition fell upon them both.

Every spring scores of people flock to the Buzzard Festival at Hinckley, Ohio. They come to watch for buzzards. Most would be glad just to take a look at a buzzard. If they do see one of these" flying garbage cans", it will probably be circling high in the sky. From there it can watch the ground for signs of the waste and the dead animals on which it feeds.

The buzzard is the ugliest bird in the United States. In fact, it may well be the ugliest bird in the world. It has a small, bare, pink head. Its thick body is covered with dark, rough feathers.

In spite of its looks, the buzzard is important to the people of Hinckley. It is their first sign of spring. After a winter in the south, buzzards return to their homes in the north. In the Hinckley area, they always return on March 15. No one knows why. But they have come back to Hinckley Ridge on that day, sure as clocks work, for at least forty years.

The excitement starts in February. By the middle of March it has reached a high peak. Bets are placed. Prizes go to the person who sees the first buzzard. Radio stations and newspapers tell of the coming festival. And on the weekend after March 15 the people of Hinckley hold their Buzzard Festival.

The people come and look around. They chat. They eat their fill of pancakes and sausages. Then they drive past Buzzard's Roost on Hinckley Ridge.

A lot of them stop near the road at the stand set up to give information to visitors. There they can hear, from a recording, the main facts about the buzzard. They can see a stuffed buzzard. They can look at some pictures taken of buzzards in other years. With good luck and a strong pair of field glasses, they may sight one or two live buzzards high in the sky.

Buzzards may be ugly. They may be "flying garbage cans". But in Hinckley they are just as welcome as the swallows in Capistrano, California. It would be a sad spring indeed if the buzzards ever failed to come back to Hinckley Ridge.

1.A good title for this story would be __________.

A．The Hinckley Buzzard Festival

B．Buzzard, the Ugliest Bird

C．Why the Buzzard Has a Pink Head

D．The Return of“The Garbage Can"

2.The buzzard is called the "flying garbage can" because it __________.

A．is ugly B．eats waste and dead animals

C．looks like a garbage can D．collect rubbish on the ground

3.The surprising thing about Hinckley's buzzards is that＿.

A．they spend the winter in the south

B．they come very close to the town

C．they return on the same day each year

D．both buzzards and swallows return to Capistrano on March 15

4.At the information stand, visitors to Hinckley's Buzzard Festival can _________.

A．learn some facts about the buzzard

B．easily see a live buzzard

C．take some pictures with the background of live buzzards

D．feed their fill of pancakes and sausages to buzzards

Today, over six billion people live on the planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, the icy continent surrounding the South Pole, you will not find anyone who lives there all the time.

First, Antarctica is the coldest place on Earth. For example, it can be –l30℃ in the winter. Humans cannot live in this kind of environment. Because it is so cold, very few plants or animals live there. This means there are no farms and no places to find wild plants or animals to eat.

Second, Antarctica can be dangerous. Many people think that it is safe to travel to Antarctica in the summer months when it is warmer. However, Antarctica is mostly ice, so when it’s summer, the ice melts. When the ice melts, the ice can break. So, people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die.

Another serious problem in Antarctica is the sun. Because Antarctica is mostly ice, there are no trees so there is no shade. Also, the ground is mostly white ice so the sun bounces off (反射) it. The light from the sky and the light from the ground can burn people’s skin and hurt their eyes. People must be very careful in this situation. For example, they must wear sunglasses to protect their eyes. They must also cover their hands and faces all the time.

Although Antarctica is a tough place to live, explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swam (沼泽) and forests.

1.This text is mainly about _____.

A. the discovery of Antarctica

B. how people travel around Antarctica

C. different animals found in Antarctica

D. why it is difficult to live in Antarctica

2.We can learn from the text that _____.

A. Antarctica is a place with no animals

B. no people can survive in Antarctica

C. Antarctica is colder than any other continent on Earth

D. the temperature in Antarctica is below zero all the time

3.When is the most dangerous time to travel around Antarctica?

A. In spring. B. In summer. C. In autumn. D. In winter.
