Five years ago, David Smith wore an expensive suit to work every day. "I was a clothes addict(有瘾的人)," he jokes. "I used to carry a fresh suit to work with me, so I could change if my clothes got wrinkled(有褶皱的)." Today David wears casual clothes (便装) to the office. He hardly ever wears a necktie. "I am 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. This became known as "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 Owen Black, the owner of a software company, "so it's hard to hire people if you have a conservative (保守的) dress code." Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Company, 85 percent of employers said that they believe that casual dress improves employee morale (心境, 士气). Only 4 percent of employers said that casual dress has a negative influence 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."

    It's common knowledge that there are many benefits to being fit, but one large new study found that skipping out on the gym is practically the worst thing you can do for your health. In fact, the study claims not exercising might be more harmful to your health than smoking.

    New findings, published Friday in the journal JAMA Network Open, detail how researchers at the Cleveland Clinic studied 122,007 patients from 1991 to 2014, putting them under treadmill (跑步机) testing and later recording death rates. Researchers found a clear connection between a longer, healthier life and high levels of exercise. The report calls for health care professionals to encourage patients to achieve and continue a strong and healthy fitness routine.

    Although it is widely understood that an active lifestyle can lead to a healthy life, the study concludes that a lifestyle which involves much sitting but little activity is equal to having a major disease and the simplest cure is exercise.

    Dr Wael Jaber, co-author of the study, called the results totally surprising. “Being unfit on a treadmill or in an exercise stress test has a worse prognosis (病情预断), as far as death, than being a smoker or suffering from high blood pressure,” Jaber told CNN. “We've never seen something as noticeable as this and as objective as this.”

    The study also took a look at the risk of being overactive and found that extreme exercisers do not face higher risk of death: the research found that the more a person exercises the lower their death rates.

    One of the most famous buildings in the United States is Carnegie Hall, the home of classical and popular music concerts in New York. Carnegie Hall is known not just for its beauty and history, but also for its amazing sound. Carnegie Hall is named after Andrew Carnegie, who paid for its construction. Construction of Carnegie Hall began in 1890 and the official opening night was on May 5th, 1891.

    The hall was owned by the Carnegie family until 1924 when it was sold to Robert E Simon. The building became very old and in 1960, the new owner made plans to destroy it and build an office block. Isaac Stem led a group of people who fought to save Carnegie Hall and finally, the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.

    Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall's concert history.

    Carnegie Hall is actually made up of several different halls, but the Main Hall, now called the Isaac Stem Auditorium, is the most famous. The hall itself can hold an audience of 2,804 in five levels of seating.

    Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall's history. Question: “How do I get to Carnegie Hall?” Answer: “Practice, practice, practice.”
