    It's generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.

    It's undeniable that behavior comes from our inner dispositions(性情), but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by observing our own behavior. We can be strangers to ourselves. If we knew our own minds, why should we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually, we often need to look to our behavior to figure out who we are.

    Moreover, we don't just use our behavior to learn about our particular types of character — we infer characters that weren't there before. Our behavior is often shaped by little pressures around us, which we fail to recognize. Maybe we recycle because our wives and neighbors would disapprove if we didn't. Maybe we buy lattes in order to impress the people around us. We should not mistakenly believe that we always behave as a result of some inner disposition.

    Whatever pressures there can be or inferences one can make, people become what they do, though it may not be in compliance(符合) with their true desires. Therefore, we should all bear in mind Kurt Vonnegut's advice: “We are what we pretend to be, so we must be careful about what we pretend to be.”

      Held on the second Wednesday of March each year, No Smoking Day helps people across the UK who want to stop smoking. The activity encourages and helps smokers to give up, and publicizes(宣传) the many sources of help offered to people. Each year over a million smokers take part in the day, while about 40,000 actually give up smoking.
      The much-publicized effects of smoking include increased risk (风险) of heart disease, lung cancer and asthma. However, smoking also causes dull skin and wrinkles. The reducedamount of oxygen getting to the skin accelerates (加速)aging, and makes the skin look sallow (病黄色的). And while many smokers believe that cigarettes help them to cope with stress (对付压力), scientific research has shown that worry levels actually go down after giving up smoking.
    Set a date and time to stop, and keep to it .Talk to your doctor about whether any kind of medicines might suit you. Find out if there is a stop-smoking health center near you .Try to get the help of your friends and family. Keep away from situation in which you used to reach for cigarette.
