"There are fundamental public health problems, like dirty hands instead of a soap habit, that remain killers only because we can't figure out how to change people's habit," said Dr. Curtis, the director the Hygiene Center at the London School of Hygiene & Tropical Medicine. " We wanted to learn from private industry how to create new behaviors that happen automatically. "
The companies that Dr. Curtis turned to-Procter & Gamble, Colgate-Palmolive and Unilever-had invested hundreds of millions of dollars finding the subtle cues in consumers' lives that corporations could use to introduce new routines.
If you look hard enough, you'll find that many of the products we use every day-chewing gums, skin moisturizers, disinfecting wipes, air fresheners, water purifiers, health snacks, teeth whiteners, fabric softeners, vitamins are results of manufactured habits. A century ago, few people regularly brushed their teeth multiple times a day. Today, because of shrewd advertising and public health campaigns, many Americans habitually give their pearly whites a cavity- preventing scrub twice a day, often with Colgate, Crest or one of the other brands.
A few decades ago, many people didn't drink water outside of a meal. Then beverage companies started bottling the production of far-off springs, and now office workers unthinkingly sip bottled water all day long. Chewing gum, once bought primarily by adolescent boys, is now featured in commercials as a breath freshener and teeth cleanser for use after a meal. Skin moisturizers are advertised as part of morning beauty rituals, slipped in between hair brushing and putting on makeup.
"Our products succeed when they become part of daily or weekly patterns", said Carol Berning, a consumer psychologist who recently retired from Procter & Gamble, the company that sold $76 billion of Tide, Crest and other products last year. "Creating positive habit is a huge part of improving our consumers' lives, and it's essential to making new products commercially viable. "
Through experiments and observation, social scientists like Dr. Berning have learned that there is power in tying certain behaviors to habitual cues through ruthless advertising. As this new science of habit has emerged, controversies have erupted when the tactics have been used to sell questionable beauty creams or unhealthy foods.
According to Dr. Curtis, habits like hand washing with soap______.
A．should be further cultivated
B．should be changed gradually
C．are deeply rooted in history
D．arc basically private concern

Most people have plenty of insecurities, and this seems like a situation that will bring them out. If parents, teachers or peers mocked your foibles as a child, you fear a repeat. If you were under pressure to be perfect, you are terrified of failing in the most public of ways.
While extroverts will feel less fear before the ordeal, it does not mean they will necessarily do it better. Some very shy people manage to shine. In fact, personality is not the best predictor of who does it well. Regardless of what you are like in real life, the key seems to be to act yourself.
Actual acting, as in performing the scripted lines of a character other than yourself, does not do the job. While politicians may limit damage by having carefully rehearsed, written screeds to speak from, there is always a hidden awareness among the audience that the words might not be true.
Although, as Earl Spencer proved at his sister Princess Diana's funeral, it is possible both to prepare every word and to act naturally. In script. rarely works and it is used as a crutch by most people. But, being yourself doesn't work either. If you spoke as if you were in your own kitchen, it would be too authentic, too unaware of the need to communicate with an audience.
I remember going to see British psychiatrist RD Laing speak in public. He behaved like a seriously odd person, talking off the top of his head. Although he was talking about madness and he wrote on mental illness, he seemed to be exhibiting rather than explaining it.
The best psychological place from which to speak is an unselfconscious self-consciousness, providing the illusion of being natural. Studies suggest that this state of "flow", as psychologists call it, is very satisfying. Whether in normal life or making speeches, the key is to remind yourself that, contrary to what your teachers or parents may have implied, your best is good enough. In the zone, a strange place of authentic falsehood and shallow depth, play is possible.
For most people the biggest fear for public speaking is ______.
A．looking foolish
B．failing in words
C．not attracting attention
D．appearing pressurized
