Two Christmas traditions have come under attack in recent years from environmentalists: Christmas cards and Christmas trees.

Paper cards are seen as wasteful and, for some people, going card-free is another way of going green. They also argue that in a world of e-mail, Skype, Facebook and Twitter, people are in touch all the time anyway; they no longer need the yearly card that connects them with long lost friends. If you want to send Christmas greetings, there are free e-cards, which get the job done with no postage or wasted paper.

However, especially for people who didn’t grow up with e-mail, there is something missing from a Christmas e-mail. The first Christmas cards appeared in London in 1843 and were designed by the same man who had introduced the world’s first postage stamp three years earlier. His name was Sir Henry Cole.

They rose in popularity throughout the 20th century. Many people sent cards that were sold for charity. The most famous of these are the ones sold for UNICEF. In the UK this year, in the three weeks before Christmas, the post office expects to handle 100 million cards every day. Environmental awareness also means that nowadays many people recycle their cards; this helps raise money to plant more trees, as well as recreating more paper.

When we think of trees at Christmas, there is one that immediately springs(跃入)mind---the evergreen tree that people decorate with ornaments and place their presents under. The custom dates back almost a thousand years to Germany. Nowadays 33 to 36 million Christmas trees are produced in America and 50 to 60 million in Europe each year. Some trees are sold live with roots and soil so people can plant them later and reuse them next year.

Some people prefer artificial trees as they are reusable and much cheaper than their natural alternative. However, environmentalists point out that they are made from petroleum (石油) products and so have many pollution issues.

Two heads are better than one. After all, when trying to make decisions, it's good to have a second opinion. But what about a third, fourth — even twelfth? What group size is best for making decisions quickly? For ants, four to six heads surpass one ― and also outperform 12 or 24. That's what Sylvia Zamescu now reports.

The 18-year-old senior at Catalina Foothills High School in Tucson, Arizona isn't generally into ants. She's interested in decision-making, especially by people. Last summer, Sylvia read that social insects such as ants and bees can be used to model decision-making. Ants, for example, forage for food. When an ant finds it, it takes a bite and heads back to the nest. On the way; the ant leaves a scented trail for other ants to pick up. Back at the nest, the ant vomits up its meal into the mouth of other ants. Those nest-mates then decide with the first ant whether the food is good enough to deserve a trip back for more. If it is, they follow the first ant's scented trail to lunch.

When there are too few ants, it could take a long time for one ant to spread the word If there are too many, it's hard to “tell" each about the find. What's the right number for foraging success? Sylvia decided to find out. She contacted professors at the University of Arizona in Tucson to look for someone who would let her study decision-making by ants in their lab. Professor Wulfila Gronenberg answered her email.

Working with one of Wulfila's graduate students, Sylvia set up an experiment She tested the behavior of one, two, four, six, twelve and twenty-four ants. Each group was placed in a large box al taped "starting line". At the other end of the box were two bricks of sweetened gelatin （动物胶） one contained only 3 per cent sugar, and the other 30 per cent. Sylvia timed how long it took each group of ants to find the food. She also measured how much time they spent around each sweet treat.

When there were just one or two ants, the discovery was slow. The same was true when she set twelve or twenty-four ants loose. But four to six ants? Perfect! These medium-size groups found the food forest. They also figured out quickly that the sweeter food was better.

Similar work has been done on bighorn sheep, fish and fruit flies. "It may not be four to six animals, but it's the same principle," Sylvia says. A medium-size group "is optimal". So when faced with a new decision, two heads are better than one. But too many heads are too much. Like the ants, a good decision may just require a happy medium.

1.What gave Sylvia the idea for her research?

A.Her interest in social insects.

B.An article about social animals.

C.A university professor's invitation.

D.Her doubt about a science report.

2.What do we know about Sylvia's experiment?

A.She set it up with Professor Wulfila Gronenberg.

B.There were two large boxes at the "starting line".

C.There were several kinds of foods for the ants.

D.She divided the ants into six different groups.

3.What did Sylvia find out about ants?

A.They make decisions faster in medium-sized groups.

B.They are better at finding food in smaller groups.

C.They perform much more smartly in larger groups.

D.They make better decisions when working together.

Two hundred years after Charles Darwin’s birth, studies have found new details of his life at the University of Cambridge. Six leather-bound ledgers(皮革账本) discovered in the university show this. 1.

He lived in the most expensive rooms provided for a rich student at his time. 2. He had someone to clean his room, make his bed and take care of the fire in his bright rooms. He hired a dishwasher, a clothes washer and a man who cleaned his shoes. A tailor(裁缝), hatter and barber made sure he was well presented. A chimney cleaner and a coalman kept his fire going. Christ’s College’s basic food was meat and beer. 3.

4. Later he described this time as the most joyful of his happy life. That large sum(金额) would have been fairly common for a student at Cambridge in the 19th century. The bills were paid by his wealthy father, Robert Darwin, a doctor.

In those days Cambridge was full of rich students living a pretty good life and Darwin was just one of them. Thanks to the richness, he was able to hire servants to help with the daily life. 5. He would be out shooting, collecting beetles, doing his scientific hobbies or visiting friends. He played cards and drank wine at night, just like students always have.

A. And thus he had plenty of time for socializing or private study.

B. The findings were published on the Internet.

C. So he paid five and a half pence extra each day to have vegetables.

D. He had several people to help him to deal with the daily housework.

E. He enjoyed the kind of comfortable university life that most of today’s students can only dream about.

F. When you look at the ledgers, you can find there were many rich students in Cambridge.

G. Darwin’s bill topped 636 pounds during his three years of study at Cambridge.
