People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House-building becomes a great challenge（挑战）to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.
59．From the passage, we can conclude that __________.
A．people will no longer consider building materials in the future
B．energy-saving buildings will become more popular in the future
C．almost all people will move into the houses heated by large rocks
D．energy engineers will devote themselves only to modern technology
【实战演练练习十】（05 全国卷Ⅲ E 篇）
Last year my sixth-grader daughter, Elizabeth, was forced to put up with science. Her education, week after week ,contained mindless memorization of big words like “batholith” and “saprophyte”. She learned by heart the achievements of famous scientists who did things like “improved nuclear fusion(核聚变)” —never mind that she hasn’t the least idea of what nuclear fusion means .Elizabeth did very well (she’s good at memorizing things). And now she hates science. My eighth-grader son, Ben, also suffered from science education. Week after week he had to perform lab experiments with answers already known .Ben figured out how to guess the right answers, so he got good grades. Now he hates science, too.
Science can provide an exciting way to develop children’s curiosity .Science education should teach ways to ask questions and seek answers. But my children got the mistaken idea in school that science is difficult, dull and has no relation to their everyday interests.
