What is your favorite color Do you like yellow, orange and red If you do, you must be an optimist (乐观主义者), a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist (悲观主义者). At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, as well as the effect that colors as we grow up. We are born with our preference. If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly. Colors do influence our moods there is no doubt about it. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area until it was repainted green. The number of suicide attempts immediately fell sharply; perhaps it would have fallen even. The number had been done in pink or baby blue.

In everyday usage "hot" means "having a lot of heat". Many people think that "cold" is something completely separated from heat. But this is not true. "Cold" simply means "having little heat". Your life depends on heat. In fact, every living thing depends on it. Without heat, every living thing would be frozen to death. All living things get their heat from the sun, which provides the conditions in which life is possible. Since before the dawn of history, man has been able to make his own heat. He has been able to release the sun’s heat that is trapped in things such as wood, coal, and oil. And he has been able to use this heat. Heat has made civilization possible. With heat, man could melt metals. As man learned to use metals and fuels, industries grew. As a result, engines were invented. These are machines that change heat energy into mechanical energy. Engine can do the work of many men. Without engines industrial civilization is impossible. Yet when the first engines were built in the 17th century, men were still wondering about the nature of heat. "What is it" they asked. Not until the early years of the 19th century did they find the right answer. Your life depends on heat. The sentence means ______ .
