Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and sports shirt—to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday, but only on Friday. This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss Company, 85 percent of employers said that they believe that casual dress improves employee morale（士气）. Only 4 percent of employers said that casual dress has a negative effect on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

Antarctic seabirds are breeding（繁殖）later, because thinner sea ice is causing their food supplies to decline, a new study says. The birds, which nest in East Antarctica, have delayed their spring arrival by an average of nine days and egg-laying by an average of two days over the past 50 years, according to polar researchers from the French National Center for Scientific Research in Villiers en Bois, France, study authors Christophe Barbrand and Henri Weimerskirch attribute this later breeding activity to decreases in sea ice caused by climate change.

The researchers say the disappearing sea ice, combined with a longer sea-ice season, has interfered with the birds’ breeding cycle by reducing the amount of krill（磷虾） and other prey（猎物）available in early spring in Antarctica. Because Antarctica’s seasons are opposite those in the Northern Hemisphere, spring on the icy continent begins in October.

The study is based on data collected at seabird colonies between 1950 and 2004 in Adélie Land, on the eastern edge of the frozen continent.

The findings were published in the journal Proceedings of the National Academy of Sciences.

Of the nine species studied, some arrived up to 30 days later than they had in previous years.

Despite much later arrivals, the birds are laying their eggs at pretty much the same time as they had in the past. In the most extreme cases, birds were laying their eggs an average of 3. 7 days later in the season than they were 50 years ago.

A. The food there has been polluted.

B. The sea ice doesn’t shrink any more.

A. October.                                                     B. September.

One day a child was play with a vase of great value. He careless put his hand into it. Hard as he tried, he

could not pull it out. His father tried his best, too, but their efforts were in a vain. They were thinking of breaking the vase whenever the father said, “Now, my son, why have one more try? Open your hand or hold your fingers out straight as you saw I doing, and then pull.” To his surprise, the child says, “I can’t hold my fingers straight like that, because I don’t want to drop my penny.” Thousand of us sometimes are so busy hold on to the world’s worthless penny that we cannot achieve liberation.
