Hibernation is a time when animals “sleep” through cold weather. With true hibernation, the animal can be moved around or touched without knowing it. Some animals only go into a temporary sleep time and can get up quickly like bears. We are going to use the word “sleep” sometimes, but hibernation is different from regular sleep. With normal sleep, the animal moves a little, has an active brain, and can wake up very quickly while with true hibernation, the animal appears as if dead.
During the fall, hibernating animals eat more food than usual. Their bodies will live off their body fat as they “sleep” through winter. The animal will use up the body fat it stores and not lose any muscle. This causes the animal to come out of hibernation thinner but still as strong as it was in the fall. The animals get their winter nests, and dens ready. Different kinds of animals hibernate in different kinds of safe spots. When they go into hibernation and their bodies slow down, enemies can get them more easily. They try to pick the safest place to spend the winter away from these enemies.
Hibernation is the way that animals adapt to the climate and land around them. Animals must be able to live through extreme cold or die. Animals hibernate-or go into a deep sleep-to escape that cold. They also do this because it is really hard to find food during the winter.
When an animal begins to hibernate, its body temperature drops to a very low degree so that it almost matches the temperature outside. The animal's heartbeat and breathing rate slow down, too. This is when that stored fat that the animal packed on in the fall comes in handy. This stored fat lasts long because their bodies are slowed down so much that they don't need much energy.

2 . No matter who you are or where you come from, one thing is certain: You are acquainted with the mosquito-although you probably wish you weren't. Mosquitoes are everywhere. They can be found all over the world, and they come in more than 2,500 species. Somewhere, at some time, you have surely met at least one.
No one loves the mosquito. But unfortunately the mosquito may decide that she loves you. She? Yes, she. Did you know that only the female mosquito bites? Well, it's true. And it's not because she's unfriendly; she needs blood to reproduce.
Do you know how the female mosquito decides whom to bite? She's quite selective, and she chooses her victims carefully. First, she uses sensors to find her victim. These sensors are located on her two antennae and her three pairs of legs. With these sensors, she tests your body moisture, body warmth, and chemical substances in your sweat. If she likes what she finds, she bites. But if you don't appeal to her, she'll reject you for someone more appetizing. The next time a mosquito bites you, just remember that you were chosen. You're special.
If the mosquito likes you, she settles onto your flesh very gently, and she breaks your skin with her proboscis tip. Proboscis tip? What's that? It's a kind of mouth and it sticks out just below the mosquito's eyes. It contains six sharp instruments called stylets. She stabs all six stylets into your skin at once, and if she hits a blood vessel, she'll get a full dinner in about a minute. All this usually takes place so quickly and quietly that you may not have suspected anything was happening.
All mosquitoes, male and female, pass through their early stages of development in or near water. In fact, mosquito eggs will not hatch without water-although the eggs can survive up to five years on dry land waiting for water. It is not surprising that heavy rains produce large numbers of mosquitoes.
But why? Why did nature bother to create mosquitoes? Just to annoy us? Probably that wasn't the main reason. Male mosquitoes live on the nectar of flowers, and some scientists believe that they pollinate the flowers as they fly from one to the other. Of course, mosquitoes have to reproduce, and unfortunately that's where you and I come in. Like it or not, mosquitoes are here to stay. Ouch! (Slap!) One just bit me!

5 . On Thursday, some scientists will find themselves in the media spotlight as the latest winners of a prize for discoveries celebrated the world over. No, it is not the Nobel Prize. It is the Ig Nobel Prizes, whose stated aim is to ''honor achievements that first make people laugh, and then make them think''.
Since their launch in 1991 by a US-based science magazine Annals of Improbable Research, the ''Igs'' have become a highlight of the scientific calendar, taking place a few days before the announcement of the real Nobels. The prizes are handed out by real Nobel winners at Harvard University, with many of the winners turning up to accept their award in person.
The range of breakthroughs is certainly impressive. In 2001 the physics award went to Dr David Schmidt of the University of Massachusetts for his research into why shower curtains tend to billow inward, while the 2005 Ig for psychology went to a team at Keio University, Japan, for training pigeons to tell the difference between the paintings of Picasso and Monet. Not everyone has seen the funny side of the Ig Nobels, however. In 1995 a team of British researchers won the physics Ig for research into why breakfast cereal goes soft and wet, prompting some newspapers to ask why taxpayers' money was being wasted on such trivial(琐碎的,无价值的)research. In fact,the project had been funded by a leading cereal maker rather than the UK taxpayer.
Even so the controversy(争议)led Britain's chief scientist, professor Sir Robert May, to ask the organizers not to award any more Igs to UK researchers,who were emerging as embarrassingly frequent winners of the prizes. With maintenance of reputation being so important among scientists these days, Sir Robert's request was understandable. But it also ignores the fact that many major scientific advances have come from research into ''trivial'' questions.
The best-known example is Newton's discovery of the law of gravity after he saw an apple fall in his mother's garden. More recently, the sight of a plate spinning through the air in a university cafeteria was enough to set the American physicist Richard Feynman on his way to a Nobel Prize. Interested in its rapid wobbling(摇晃), Dr Feynman analyzed the problem mathematically and showed that as long as the wobbles are small, they occur at twice the spin rate of the plate. Delighted by his discovery, he told his friend and colleague Hans Bethe who thought it was all rather, well, trivial. Yet it inspired Dr Feynman to investigate the spin of the electron which, in turn, led to work on quantum electrodynamics for which he won a share of the 1965 Nobel Prize for physics.
Some of the scientists who find themselves awarded Igs on Thursday might prefer to have won the ''real'' thing. They might even worry about being looked down upon by their peers. Yet whether it is the spinning of a plate or the fall of an apple, the truth is that nature herself doesn't understand the meaning of ''trivial''.

7 . A young man has just returned from a terrific first date. He wants to send flowers to let his date know he enjoyed being with her, but he's not sure what to send. A dozen red roses? No, too formal for a first date. A bouquet of wild flowers, perhaps? Still not sure, he picks up the phone and calls a florist for advice. The next day his date calls, thanking him for the beautiful yellow roses.
Florists enjoy helping people express themselves with flowers. Flowers can help, people share all sorts of feelings. For instance, flowers help people say "Congratulations!" to a friend who gets promoted. Flowers can also express feelings hard to put into words. They help say "I'm sorry" to the wife whose husband forgot her birthday. From birth to death, and the holidays in between, flowers add color and meaning to life. That's why florists' services are always in demand.
In the past, florists just sold flowers to customers, who arranged them on their own. But today's florists are skilled designers, arranging flowers in ways that best express their customers' feelings.
Formerly, florists learned on the job. Today, however, many florists earn diplomas in floral design in as few as 75 hours of classes. They gain a knowledge of flower varieties and develop an artist's touch. These skills help florists make arrangements that fit customers' tastes and meet their budgets.
Compared to most start-up businesses, opening a flower shop takes little money. As a result, many florists open up their own shops soon after earning their diplomas.
One of their first priorities is establishing good customer service. Their customers have come to expect same-day delivery. So florists must be able to work quickly, especially during holiday rushes. But florists don't mind. For them, the more arrangements they make, the more people they touch-with flowers.
1. Compared with florists today, florists in the past___________.A.arranged flowers as customers requested |
B.didn't just sell flowers to customers |
C.didn't necessarily have diplomas in floral design |
D.had a better knowledge of flower varieties |
A.Congratulations. | B.Apology. |
C.Deep love. | D.Good impression. |
A.A florist delivers flowers within the same day of ordering. |
B.A florist arranges flowers with an artistic touch. |

8 . What to endure before publication?
It takes a lot to write a novel. Even those who haven’t tried would say, “Well, duh!” to this. But it’s not much the mind space or the considerable time it takes to write a novel that is as discouraging as how many times any writer must go back to the drawing board for yet another draft. To really ready a novel for publication, a writer must spend time with his or her book. Like any promising relationship, you, the writer, must date your novel, take it out to dinner, meet its parents, and see it through its most trying and desperate times. As a writer, you have to stay up all night with your novel crying and talking and sometimes even pulling your hair out before that perfect moment of inspiration can truly help you cross the finish line.
For many published authors I know, myself included, a completed novel takes them about 10, that’s right, 10 drafts, and at least a year of real editing. Will you be spending every single second editing your novel? No, of course not. Just as drafts need some real time on the surgery table, they also need rest in the recovery room. You don’t nurse a relationship by spending every waking second with them until you can’t stand the sight of each other, and you can’t produce a novel by breathing down its literary neck. However, a novel should undergo many drafts — and different kinds of drafts — before declaring it ready for an agent or editor to see.
Everyone has their own way to write a novel, and not all craft advice (or even craft “rules”)should all be followed by everyone, but when it comes to the many drafts of a novel, there are specific things a writer should focus on during each revision to help create a smooth transition from the initial idea to final products.
1. People are discouraged from writing a novel mainly because it requires ______.A.a good publisher | B.too much thinking |
C.tons of working time | D.frequent revisions |
A.writing casually thus failing to take readers’ breath away |
B.letting go a single mistake thus annoying the readers |
C.X-raying the work thus finding each literary mistake |
D.sticking too close to the work thus causing anxiety |
A.The importance of using proper transitional words in writing. |
B.The writing experience shared by famous successful write. |
C.Tips on how to make ten drafts to complete a good novel. |
D.Setbacks writers may suffer if ignoring the craft advice. |
