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."

    Americans like to travel on their yearly holiday. Today, more and more travelers in the United States are spending nights at small houses or inns(客栈) instead of hotels. They get a room with breakfast the next morning.

    Rooms for the night in private(私人的) homes with breakfast have been popular with travelers in Europe for many years. In the past five or ten years, these bed and breakfast places have become popular in the United States. Many of these American's bed-and-breakfast inns are old historic buildings. Some bed-and-breakfast inns have only a few rooms, while others are much larger. Some inns do not provide telephones or televisions in the rooms, but others do.

    Staying at a bed-and-breakfast inn is much different from staying at a hotel. Usually the cost is much less. Staying at an inn is almost like visiting someone's home. The owners are glad to tell about the areas and the interesting places to visit. Many vacationers say that they enjoy the chance to meet local families.

    Wouldn't it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?

    In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within a decade or so, we'll be able to communicate with one another via small earpieces with built-in microphones. That's because technological progress is extremely rapid. It's only a matter of time. Indeed, some parents are so convinced that this technology is imminent that they're wondering if their kids should even learn a second language.

    It's true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It's not good to sleep too much.” Replacing a word with its equivalent (同义词) in the target language is actually the “easy part” of a translator's job. But even this seems to be a discouraging task for computers.

    It's so difficult for computers because translation doesn't—or shouldn't—involve simply translating words, sentences or paragraphs. Rather, it's about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.

Think about all the related clues that go into understanding an expression: volume, gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.

    Therefore, we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.

    After I visited my elder sister's house, I was reminded just how different the apartment living with a child was. She has a nice big house with a few floors, a big backyard and lots of toys. Her house is my son Tom's little piece of heaven. At her house there are little toys, big toys, a doll house, a play house and more! There are bedroom stocked with train tables, ride-on toys and big trucks.

    The main difference about being an apartment mom is that you cannot become a collector of “things”. I continually get rid of anything too large. When Tom was born, we made a rule that there would never be any stuffed animals in our apartment that were larger than him at that time. We also made a rule that we would only ever have at most five stuffed “anything” at one time. So far this had worked out well for us. These rules left Tom with a few special soft creatures to play with, but that can be easily put away.

    Since we want to keep the appearance of being clean city dwellers, we have limited Tom's play things to one toy basket in the main living space and one big storage bin in his bedroom. I am constantly thinking about living space when I buy anything for our little Tom. We love the storage bin in Tom's room. It is filled with fun play things. It is a place to keep his toys and everything gets pulled in and out daily. Anything that doesn't fit is often weeded out to create space.

    Tom absolutely likes going to his aunt's house and pulling out every single toy available to him. Of course, Tom does not notice that when he returns home he only gets one basket of toys instead of many rooms of toys. Right now Tom lives fully in his 1,100-square-foot apartment and seems very satisfied with his basket of toys.

    Christmas is a time for eating great food, giving and receiving presents, and most importantly spending time with your family watching some classic Christmas movies.

The Grinch (2000)

    This is a Christmas must-watch and one of Jim Carrey's best performances. It was also originally a nursery tale book written by Dr Seuss. It's the story of a green monster who wants to ruin Christmas but who in the end discovers the power of love and generosity. I promise it's a great film with plenty of laughs along the way.

    Love Actually (2003)

    While this is not a personal favourite of mine, people in the UK absolutely love this film. It has many featuring actors and actresses. It might be a little difficult to follow as there are complex plots, so I recommend watching a translated version or enabling subtitles (字幕) in your native language. However, the heart-warming elements of the film make it worth watching.

    Home Alone (1990)

    This amusing masterwork is one of my favourite films of all time. It tells the story of a boy, Kevin, who is left alone in his house when his large family forgets to take him on vacation with them. While the families are away, burglars try to rob the house and Kevin must protect his home by setting traps. The trips, falls and traps will have you laughing out loud as you watch a 10-year-old boy beat two grown men.

    Miracle on 34th Street (1994)

    You can't have Christmas in an English-speaking country without watching this movie. It's not funny like Home Alone or The Grinch, but it is incredibly touching. It's about a man who claims to be Santa, but nobody believes him except a lawyer and a little girl. The story-line may seem a little childish but you can enjoy it at any age.

    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
