Question

Both the Eskimos and the Plains Indians used open fires in their shelters for warmth but with very different consequences(结果)．The Eskimo house was an airtight igloo made of blocks of ice with a small tunnel-like entrance and a small chimney in the center for smoke from the fire．Temperatures inside the structure easily reached 70 to 80 degrees Fahrenheit although outside temperatures frequently dropped well below zero．Often the igloo was so hot that the loss of body fluid through perspiration would force the Eskimos to drink cup after cup of ice water．The Plains Indians, on the other hand, placed their fire in a tepee, made with long poles and animal skins with an entrance cut directly into one wall．In contrast with the Eskimo shelter, the tepee was far from airtight; drafts(穿堂风)came in around the door and through gaps between the skins．At night, the Indians would crawl under their blankets, cover their heads, and shiver all night－so much that the blanket would shake!The difference between the Eskimo igloo and the Indian tepee was insulation.(密封性)：the igloo’s walls were solid and airtight whereas those of the tepee permitted a great deal of air to enter． (1) This passage most likely occurs as part of ________． [　　] A． a weather forecast B． a book on fire prevention． C． a report on animal conservation D． a magazine on house construction (2) From the passage it can be inferred that ________ [　　] A． to enter an Eskimo house, one had to go through a long tunnel B． the Eskimo igloo had better insulation than the Indian tepee C． the Plains Indians enjoyed living in their shelters in winter days D． there was a small chimney in every Indian tepee to release smoke from the fire (3) This passage is written mainly to ________． [　　] A． compare B． tell a story C． amuse the readers D． report a scientific discovery
