单选题{{B}}Passage 28{{/B}} In every day 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 very little heat." Your life depends on heat. In fact, every living thing depends on it. (28) {{U}}Without heat, every living thing would be frozen to death.{{/U}} All living things get their heat from the sun, which provides the conditions in which life is possible. Since 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 19th century did they find the right answer.

单选题Questions 11 to 15 are based on the following passage: Adam Smith was the first person to see the importance of the division of the labor. He gave us an example of the process by which pins were made in England. "One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, and a fifth gives it a head. Just to make the head requires two or three different operations. The work of making pins is divided into about eighteen different operations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them. Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4, 800 pins a worker. (79) But if all of them had worked separately and independently without division of labor, they certainly could not have made twenty pins in a day and not even one. There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this, (80) but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new, it only enables people to produce more of what they already have.
