The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    1). How many times did you brush your teeth yesterday?

    Finding：A full 33% of seniors brush their teeth only once a day.

    Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    2). How many times did you wash your hands or bathe yesterday?

    Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

    Step：We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    3). How often do you think about fighting germs?

    Finding：Seniors are not fighting germs as well as they should.

    Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    There is no doubt that to study abroad gives you an excellent opportunity to learn things which are very helpful in your career building. Today Canada has earned a good name in providing quality education and safe healthy environment for its students. That is why more than 130,000 international students enroll (登记入学) every year in famous Canadian universities. It is an ideal education destination and gives students a unique experience education and its versatile (多样的) arts and culture. Canada spends a lot on education and is ranked the highest in G-8 countries.

    To study in Canada is very cheap．These universities are affordable compared to other universities in the world such as in the US, New Zealand and UK where cost of education and living is very high．According to a survey in 2006, “Canada offered the lowest tuition fees (学费) for foreign students compared to UK and Australia.”

    The low rate of crimes and the peaceful safe environment of the country also attract a lot of international students to Canadian universities. Canada has 92 universities and 175 community colleges and university degrees have three levels—Bachelor's, Master's and Doctoral.

    A Bachelor's degree in Canada is for three or four years' full-time study depending on the nature of the program you are doing. On the other hand, a Master's degree consists of two years of study. For a Doctoral program in Canadian universities, you require a minimum (最低/小的) of three to four or sometimes five years of research and study.

    You can also find many diploma (文凭) and certification (认证) programs in Canadian universities where the time is generally one year．Some of the Canadian universities are well-regarded worldwide and the degree and diploma obtained from these Canadian universities are recognized globally and promise bright future. After the completion of studies, a person could also find great job offers in Canada itself. International students require a work permit to work on campus.

    My motivation for starting our family tradition of reading in the car was purely selfish: I could not bear listening to A Sesame Street Christmas for another 10 hours. My three children had been addicted to this cassette on our previous summer's road trip.

    As I began to prepare for our next 500-mile car trip,I came across a book Jim Trelease's The Read Aloud Handbook. This could be the answer to my problem, I thought. So I put Roald Dahl's James and the Giant Peach into my bag. When I began to read aloud the tale of the boy who escapes the bad guys by hiding inside a giant peach, my three kids argued and wrestled in their seats. But after several lines, they were attracted into the rhythm of the words and began to listen.

    We soon learned that the simple pleasure of listening to a well-written book makes the long miles pass more quickly. Sometimes the books we read became highlights of the trip. I read Wilson Rawls's Summer of the Monkeys as we spent two days driving to the beach. We arrived just behind the power crews restoring(恢复)electricity after a tropical storm. The rain continued most of the week, and the beach was covered with oil washed up by the storm. When we returned home, I asked my son what he liked about the trip. He answered without hesitation, “The book you read in the car. ”

    Road trips still offer challenges, even though my children now are teenagers. But we continue to read as we roll across the country. And I'm beginning to see that reading aloud has done more than help pass the time. For at least a little while, we are not shut in our own electronic worlds. And maybe we've started something that will pass on to the next generation.

    Windermere Hotel

    Located in the center of London, our hotel puts guests within easy reach of London's well-known buildings. Buckingham Palace and the Royal Parks are just a short walk away. Within 1. 5 miles you can visit Westminster Abbey and the Houses of Parliament. The theatres, Harrods shopping centre, and the designer shops of Sloane Square and Knightsbridge are all only a short walk away or a taxi ride away.

    Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked? They're called “placebo(安慰剂）buttons” 一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today's levels.

    But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston， Dallas and Seattle， have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals， pressing the pedestrian button results in a reliable “Wait” light. But that doesn't necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

    “We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,'' said Glynn Barton, director of network management at Transport for London.

    These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they're running late, for example), which means that pressing the button has no effect.

    According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.

    We can achieve knowledge either actively or passively. We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.

    We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. We are used to passive learning, and it's not surprising that we depend on it in our everyday communication with friends and co-workers. Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay and rumor.

    Did you ever play the game Rumor? It begins when one person writes down a message but doesn't show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements are compared. Typically, the original message has changed.

    That's what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen to improve on it, stamping(打上标记) it with their own personal style. Yet those who hear it think they know.

    This process is also found among scholars and authors: A statement of opinion by one writer may be re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.
