单选题{{B}}Passage 33{{/B}} Penguins live together in large and busy colonies. Every pair has a little piece of ground. When a penguin wants to walk through his neighbor's ground he must ask for permission. If he does not, he will have to fight. Penguins come and go all day. They fight, fish and look after their children. (33) {{U}}All penguins are good parents--the emperor penguins are perhaps the best parents in the world.{{/U}} They walk in from the sea in the middle of the dark Antarctic winter. They choose their wives in the dark. They can only hear them--not see them. Then the females lay their eggs and go away for two months. The males look after the eggs. They hold them on their feet inside a fold of skin. If the eggs get cold there will be no chicks. There is no food. The snow falls. The wind blows-sometimes at 150 kilometers an hour. The penguins do not move. When the females return from the sea they will not remember their husbands. It does not matter. Only one thing matters-the eggs. Emperor penguins never fight-unless a penguin leaves a chick for a minute. Then they fight because they all want it. They are strange and wonderful birds.

单选题{{B}}Passage Four{{/B}} The night is not what it was. Once, the earth was cast half in shadow. Then came fire, candle, and light bulb, gradually drawing back the curtain of darkness. But a brighter world has its {{U}}drawbacks{{/U}}. An estimated 30 percent of outdoor lighting—plus even some indoor lighting—is wasted. Inefficient lighting costs U.S. about $10.4 billion a year, according to bob Gent of the International Dark Sky Association, a nonprofit that aims to control light pollution. Last year, in Sydney, an estimated 2.2 million Australians switched off their lights during "Earth Hour", briefly reducing that city's energy use by more than 10 percent. Motivated by such trends, more than two dozen cities worldwide went dim on March 29 this year in an hour-long demonstration. A number of groups are trying to measure light pollution and assess its effect on the environment in the hope that people will reduce their own contribution to the problem. Scientists are trying to report how many stars we can see. In dark rural areas, about 2,000 stars are typically visible at night, compared with "maybe five" in a bright city square—and about 5,000 in centuries past. People who are working while others are star-gazing may face the greatest risks. Nighttime exposure to white light can cause the growth of tumors (肿瘤), experiments show. Two decades of research indicate that women who work at night shifts have unusually high rates of breast cancer.
