Camels are well known for their ability to survive the hot and dry conditions of the desert,but a study suggests they once grew well in colder climates. Scientists have found fossilized(化石) parts of a leg bone belonging to a giant camel that lived in the forests of Canada's High Arctic about 3.5million years ago.
The research is published in the journal Nature Communication. Dr. Mike Buckley, an author of the paper from the university of Manchester, said, "What's special about this story is that this is the northernmost evidence of camels. "The area was warmer than today 3.5 million years ago, but the ancient giant camels would have had to face long and bitter winter, with temperatures below freezing. There would have been snowstorms and about six months of darkness.
While scientists have known for some time that camels existed in North America, with the earliest creatures dating to about 45 million years ago, they were astonished to find a species at such a latitude(纬度).
Over the course of three investigations, which began in 2006,researchers from the Canadian Museum of Nature collected 30 pieces of the leg bone from Ellesmere Island in Canada.
Their size suggested that the animal was about 30% larger than today's camels, measuring about 2.7m from foot to shoulder. Despite its size, the researchers believe it would have been similar in appearance, although it probably had a thicker coat to stay warm.
To investigate further, the team took the protein found in the bone from the fossils and modern animals. Dr. Buckley said, "The results tell us that it is a direct ancestor of modern camels. "
He said the findings provided a new insight into the evolution of this animal. "It suggests that many of the adaptations(适应) that we currently think of, in terms of camels being adapted to warm desert-like environments, could have actually originated through adaptation to quite the opposite cold, bitter environments. Camels 'humps(峰)which store fat could help get through an Arctic six-month winter. Their large eyes would have helped them to see in the low light,and their wide,flat feet would have been just as useful for walking on snow as they are on sand,"he explained.
1.What surprised the scientists when they found the giant camel fossils? ___
A.Their size. B.Their shape.
C.Their place. D.Their number.
2.According to the text, the ancient giant camels___.
A.could date to about 45million years ago
B.struggled to survive in severe conditions
C.were the first ancestors of modern camels
D.lived in an environment without light
3.Compared with modern camels, the ancient giant camels___.
A.were much taller
B.had more humps
C.were slightly stronger
D.had thinner coat
4.We can infer from what Dr. Buckley said that___.
A.giant camels had special adaptations for polar life
B.cold environments prevented giant camels developing
C.the cause of the extinction of giant camels remains unknown
D.the hard climates forced giant camels to adapt to warm environments

The British are known for their sense of humor. However, it is often difficult for foreigners to understand their jokes. The main point to remember is that the British often use understatement.

Foods from Around the World
Foods that are well known to you may not be familiar to people from other countries. Here are four people’s experiences with foreign food.
Shao Wong is a student in France. He comes from China. “I’d never tasted cheese or even milk before I came here. Cattle are rare in my part of China, so there are no dairy products. I tried milk when I first arrived in France. I hated it! I sampled cheese too, but couldn’t manage more than one bite. I love ice cream, though, and that’s made from milk.”
Birgit is from Sweden. She traveled to Australia on vacation. “I was in a restaurant that specialized in fish, and I heard some other customers order flake. So I ordered some too and it was delicious. Later, I found out that flake is an Australian term for shark. After that pleasant experience, whenever I see a new food I try it out on purpose. You know why? I remember how much I enjoyed flake.”
Chandra is a dentist in Texas. She originates from India. “I’m frightened of eating new foods because they might be made from beef. I’m a Hindu, and my religion forbids me to eat meat from the cow. It’s a sacred animal to Hindus, so that’s the reason I can’t eat hamburgers or spaghetti with meatballs.”
Nathan is American. He taught for a year in China. “My friends gave me some 100-year-old eggs to eat. I didn’t like the look of them at all. The insides were green, but my friends said the color was normal. The Chinese put chemicals on fresh eggs. Then they bury them in the earth for three months. So the eggs weren’t really very old. Even so, I absolutely refused to touch them.”
Life in a new country can be scary, but it also can be fun. Would you sample a 100-year-old egg? Would you order shark in a restaurant?

It is the season for long lines and frayed(紧张的) nerves. Here are some ways to survive a holiday flight.
Lighten up
Do yourself a favor and ship your presents. Nearly every US airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.
Weigh your options
Not knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.
Leave amateurs in the dust
Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced files, and it’s a hard walking. Plus, if you decide to cut it close you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.
Take it public
The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories have decreased dramatically(现住地). True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.
Say no to bumper cars
Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX now feature this sensible choice.
1.How does the author think of shipping gifts?
A. Unnecessary. B. Expensive. C. Inconvenient. D. Wonderful.
2.Airlines have reduced flights to _________.
A. deal with crisis B. reduce the time for leave
C. lower the cost D. provide more job chances
3. It can be learned from the passage that ______.
A. renting a car at the airport is expensive B. taxis stay at the airport free of charge
C. cars can park at the airport for free D. JFK encourages people to take a taxi
4. What’s the best title for the passage?
A. Five ways to survive a holiday flight. B. Good seasons for flight.
C. Cars at the airport. D. How to board a flight
