Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled-to $1.01 per pack-smokers have jammed telephone "quit lines" across the country seeking to kick the habit.

    This is not a surprise to public health advocates. They've studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase.

    The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.

    In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drugstore Wednesday. In Charleston, S.C., where the 7-cent-a-pack tax is the lowest in the nation, the price was $4.78.

    The influence is obvious.

    In New York, high school smoking hit a new low in the latest surveys-13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky. Other low-tax states have similarly depressing teen-smoking records.

    Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans "who choose to smoke".

    That's true. But there is more reason in keeping future generations of low-income workers from getting hooked in the first place. As for today's adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2001, when my husband arranged for me to ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time, I told my husband that I wanted to skydive. So when our retirement community announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.

    In the essay, I wrote about my desire to skydive, stating George Brush Sr. did age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that l was one of the winners. I just couldn't believe it. Inspired by this, I decided to realize my dream, even though some of my family members and my doctor were against it.

    One June 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn't frightened－I was really just looking forward to the experience. When we reached 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute （降落伞）, then we just floated downward for about five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt－much better than the hot air balloon. I was just enjoying it.

    Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don't stop living just because you are 84 years old. If there's something you want to experience, look into it. If it's something that is possible, make it happen.

    In the tenth grade, I began working for free at a vet's that was run by a friend. I wanted to get experience for what I thought would be my future job. However，on one particular Saturday morning I learnt something perhaps more important.

    The hospital was in the middle of one of the poorer sections of the city and some people could only pay for the most basic treatments. On this Saturday，a man and his young son，who was probably about 7 years old，walked in with a small cat in a cardboard box. There was something wrong with the cat's left eye. But the man could not afford to pay for the cost of the medicine. He kept quiet for a while，and then he asked where the nearest animal shelter was. Hearing this，his son cried and started to argue with him. All of a sudden，an older woman who was sitting in the waiting room stood up，walked up to the counter，and told the man that she would pay for the cost. The man thanked her and the son got to keep a healthy cat.

    I always thought it was the right thing to help out a needy person，but I only saw people do acts of kindness on TV or in movies. What the woman did made me believe that these things do happen in real life，and quite often.

    Now，when I can't decide whether to help someone who is in need，I remember this woman，and then I have the courage to step up to the plate. Sometimes other people follow.

    Education is not a bystanders sport. Numerous researchers have shown that when students participate in classroom discussion they hold more positive attitudes toward school, and that positive attitudes promote learning. It is no coincidence that girls are more passive in the classroom discussion and score lower than boys on SATs.

    We found that at all grade levels in all communities and in all subject areas boys controlled classroom communication. They participated in more interactions than girls did, and their participation became greater as the year went on.

    Our research contradicted the traditional assumption that girls control classroom communication in reading while boys in math. We found that whether the subject was language arts and English or math and science, boys got more than their fair share of teacher attention. That teachers talk more to male students is simply because boys are more aggressive in grabbing their attention by calling out answers to the teachers' questions first. While girls sit patiently with their hands raised or keep silent. Psychologist Lisa Serbin and K.Daniel O'Leary, then at the state university of New York at stony brook studied classroom interaction at preschool level and found that teachers gave boys more attention, praised them more often and were at least twice as likely to have extended conversations with them.

    Years of experience have shown that the best way to learn something is to do it yourself. It is also important to give students specific and direct feedback about the quality of their work and answers. Teachers behave differently depending on whether boys or girls are active to provide answers during discussions. During classroom discussion, teachers in our study reacted to boys answers with powerful, precise and effective responses, while they often gave girls mild and unclear reactions because of their silence. Too often, girls remain in the dark about the quality of their answers. Active students receiving precise feedback are more likely to achieve academically. And they are more likely to be boys.

    This kind of communication game is played at work, as well as at school. As reported in numerous studies, it goes like this.

    Men speak more often and frequently interrupt women.

    Listeners recall more from male speakers than from female speakers, even when both use a similar speaking style and cover the same content.

    Women participate less actively in conversation. They do more smiling and gazing, and they are more often the passive by standers in professional and social conversations among peers.

    Women often their own statements into unsure comments. This is accomplished by using qualifiers and by adding tag question. These uncertain patterns weaken impact and signal a lack of power and influence.

    Only when girls are active and treated equally in the classroom will they be more likely to achieve equality in the workplace.

    “That one looks just like a sheep! And look over there. That one looks like a horse!” Do you remember lying on your back in a grassy field on a summer afternoon, discovering the soft shapes in the clouds in the sky? Those were the good old days when you could see anything and everything in the clouds.

    But now people look at the sky and see clouds in the shape of a motor company's advertising logo (商标),or a message inviting them to go out and buy a certain brand (品牌) of beer. These cloud pictures are not products of their imaginations. Instead, they are produced by a machine. These new floating advertisements are called Flogos; the name stands for “floating logos.” They' re made from a mixture of soapy foam (泡沫)and a lighter-than-air gas such as helium, and they can be made into different sizes and shapes depending on the advertisement.

    Flogos can last up to an hour if weather conditions are good, and they can fly several kilometers high. Advertisers can rent a Flogo machine for$2,500 a day. The set-up is normally performed within 1 to 2 hours, and it will release four Flogos per minute. Advertisers can fill the air with any shape or message they want.

    Some people are worried that the Flogos might not be pollution-free. However, the Flogo's inventor insists that the soap he uses is natural, and that a Flogo just dissipates in the air, leaving nothing behind. Though it may be true that Flogos are environmentally friendly, some people believe that the natural clouds in our memory may be replaced by man-made ones. They are afraid that soon there will be nowhere left where their imaginations can float freely.
