The sun can heat houses. Solar(太阳能) heat can keep a house warm even when it is cold outside. Large windows, sun-rooms, and solar greenhouses all collect the sun's heat. Solar collectors can be placed on a roof, a wall, or anywhere the sun shines. Collectors can be made to store extra heat for times when there is no sun. The sun heats water, too. Pipe systems are put on roofs and the sun heats the water pipes. House roofs should slant (倾斜) towards the south. In a house that is built especially for solar heat, most of the rooms face south. The southern wall has double sheets of glass. The sheets are divided by a half-inch of space. This space reduces the amount of heat that escapes. The sun can still enter, though. Solar energy can be used for cooking, too. Dr Maria Telkes invented a simple stove that looks like a tightly insulated (绝缘的) box. The stove slants towards the sun. Four flat mirrors fan out from it. These mirrors reflect sunlight into the inside of the stove, which is filled with a heat-absorbent salt. Its temperature can be regulated by moving the mirrors. Because it stores up heat, the stove can be used after sunset. Solar energy is expected to become cheaper and more common in the future. Then it will be able to compete with oil and gas as a major source of energy. 69. The best title of this passage would be “ ________ ”. A. Cooking with Solar Energy B.

Dear Molly, I have a problem. My parents are always talking to me about studying. They want me to study harder so I can go to a good school.

Dear Molly, My best friend Tony is a nice young man, but he has a bad habit. He is always late. No matter where he is going or what he is doing, he is never on time.

What can I do? ---- Unhappy 77. Dear Molly, My cousin plays computer games a lot and he keeps on talking to me about various games.

Dear Molly, I’m feeling upset these days because the result of my last English exam was not as good as I had expected. My teacher comforted me, saying “Don’t worry. You can do better next time.” But I’m still feeling bad. I need your help. ----Disappointed A: Dear xx, As I see it, you have three choices. You can find a new flat for yourself, make him find a new one, or have a talk with him and see if you could both be a little less extreme in your attitudes towards housekeeping. I would suggest you start with the third. Molly B: Dear xx, You could try talking to him about the importance of being on time. If it doesn’t work, one trick you can try is to ask him to set his clock 15 minutes ahead. You could also tell him that something starts 15 minutes or more before it really starts. (责任编辑：admin) |
