However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat. Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock(家禽 ). During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as body heat given off by the animals rises to the second floor of the houses, where people live in. By sharing their houses with their livestock, people gain a source of heat. 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 couse, the warm air rises into the living areas of the houses. So these houses are energysaving. Housefbuilding bees a great challenge 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 futuer, people will be able to live in more energysaving houses. 59.

While we get on well with a number of people, we are usually friends with only a very few — for example, the average among students is about 6 per person. In all the cases of friendly relationships, two people like one another and enjoy being together, but beyond that, the degree of intimacy（親密） between them and the reasons for their shared interests vary（變化） greatly. As we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these factors（因素） are not of great importance, it is more difficult to get on with people when there is a marked difference in age and background. Some friendly relationships can be kept on argument and discussion, but it is usual for close friends to have similar ideas and beliefs, the same opinions and interests — they often talk about ―being on the same wavelength‖. It generally takes time to reach this point. And the more intimately involved people bee, the more they depend on one another. People who
