10 “ Clothes make the man” goes the old saying. Many people believe clothing choices say a lot about character as well as social status. People adopt some kind of style in daily life, usually because they are trying to fit in with certain surroundings or show their connection to a particular group, says German image consultant Beatrix Isabel Lied. This means that people use clothing to send signals to those around them: The wearer of a black polo-neck sweater (套头圆领毛衣) might be an artist, an educated man or an architect. Outdoor and nature-loving types tend to choose weatherproof （防风雨的）jackets and durable shoes instead. Women usually spend more time on clothes than men. “Clothing is not only an expression of taste, but also an expression of attitude,” says Lied. According to style advisor Lisa Zimmermann from Berlin, there is nothing superficial (肤浅的) about judging people by the clothes they wear. “It"s about the famous first 10 seconds, which is all it takes to make an impression,” she says. Apart from material, Zimmermann believes people, whether consciously or unconsciously, choose a color, which they believe suits them and the situation. Different colors can produce different effects. Black signals a sense of being something special, and it also stands for concentration. Blue, the color of the sky, stands for pragmatism (实用主义) and intellect (知识分子). “It is the color of power,” says Zimmermann. Red clothing gets the wearer noticed and can indicate an outgoing character. Yellow stands for cheerfulness and optimism, while pink is naturally the most romantic of colors. Experts say it is important to be aware of the meanings of particular colors, which can vary a lot between different cultures. What does the underlined sentence in the first paragraph mean? Clothes can decide what a man’s job is. Clothes can tell us whether a person is really a man. Clothes can tell us about a man’s character and social position. Clothes can help us choose our life style. According to Lied, an artist might wear ____________. A. a black polo-neck sweater B. weatherproof jackets C. nature-loving types D. a red sweater Lisa Zimmermann believes____________. A. there is something wrong with judging people by what they wear B. there is nothing wrong with judging people by what they wear C. people usually choose what they believe suits them and the situation consciously D. people usually choose what they believe suits them and the situation unconsciously What color stands for concentration?
