People in communities have slowly been pushed apart through the years, mostly because people simply aren’t taking the time to say a simple “hello,” After considering this phenomenon, I decided I was going to   36   the way I was doing things.
My   37   came one morning when I was in the community library. I passed by a girl who   38   her books out of her locker .Thinking like most that someone else would help her pick them up, I continued my way. However, when I had to   39   because I stupidly forgot my book, I noticed she had just finished packing them up by herself he one had stopped to   40   her.
“OK,” I thought to myself, “this is where I should have changed.”
My best opportunity came a few days later when I saw a man   41   by himself waiting for the library to open ,so I sat down next to him and began a   42  .It was difficult to get started ,and even when I had to say goodbye, almost every   43   from my new friend had a tone (语气) of doubt in it ,And who could blame him?
People aren’t used to making an   44   chat with a stranger. But a change, no matter how   45   it is needed, doesn’t just happen. It takes people like us to make it possible. I    46    you to take a small step out of your comfort zone and try to make someone’s day a little brighter, Together, we can really make   come   47    as a whole.

I want to talk about the economy．Not "the economy" we hear about endlessly in the news each day and in politicians' speeches．I want to talk about the real economy, the one we live in day by day．

         Most people aren't particularly interested in "the economy"．"Share prices are flying high; interest rates are soaring(令人伤心的）; the Dow Jones Index closed sixty-three points down on 8472．35．" We hear this and subconsciously switch off．

        Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth．The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life．

        We are supposed to be benefiting from all the advantages of a well-off society．So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives．Our towns become more and more crowded．We poison our air and seas, and our food is full of chemicals．There's something wrong here．If times were truly good, then you may think we'd all feel optimistic about the future．Yet the majority of us are deeply worried．More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations．

    The term "economic expansion" suggests something desirable, but expansion simply means spending more money．More spending doesn't mean that life is getting better. We all know it often means the opposite - greed, crime, poverty, pollution. More spending merely feeds our whole economic system, which is based on production and consumption. Unless money keeps circulating, the economy breaks down. If we don't keep consuming, the whole system goes into stalemate（僵局）．

         How do we break the cycle and make some changes? We need to become far more aware of the results of our actions. We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world. We create mountains of waste. We demand cheap food, mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land．

    The consumption（消费） culture makes us unaware of the effect of our own behavior. Our main problem is not that we don't know what to do about it. It is gathering the desire to do it．

It doesn't take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy（烟雾的）day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished（减少） lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person's individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won't work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”
