【正确答案】正确答案： According to psychologists, optimism and confidence should be the major elements for a healthy mental status. Anxiety is a mental problem, whose roots are in inner fear over the uncertainties in life. Or, say, it is a feeling of insecurity. The prospering market economy reflected in conspicuous consumption is the reason for some people's anxiety. Brand-name cars, luxurious houses and superior lives are within sight of common people with high profiles. But as they are hardly achievable of many, some people feel frustrated. Such anxiety over the worship of money, however, is not representative. The major reasons causing anxiety for most people are high house prices, education expenses and medical costs. People are living under high pressure, but they see little hope for escape as their incomes are low and their increases are slow. At a time that seems to be full of opportunities, people live with many anxieties.
