10．The word"day"has two meanings．When we talk about the number of days in a year，we are using"day"to mean 24hours．But when we talk about days and night，we are using"day"to mean the time between sunrise and sunset．Because the earth looks like a ball，the sun can shine on only half of it at a time．Always one half of the earth is having day and the other half night．At the equator （赤道） day and night are sometimes the same length．They are each twelve hours long．The sun rises at 6o'clock in the morning and sets at 6o'clock in the evening．For six months the North Pole is tilted（傾斜的） toward the sun．In those months theHemisphere gets more hours of sunlight than the Southern Hemisphere．Days are longer than nights．South of the equator nights are longer than days．For the other six months the North Pole is tilted away from the sun．Then the South Hemisphere gets more sunlight．Days are longer than nights．North of the equator nights are longer than days．Winter is the season of long days．
根據(jù)短文內(nèi)容，選出一個最佳答案．

分析 天"有兩層含義．當(dāng)我們在談?wù)撘荒甑奶鞌?shù)，我們使用的"天"是指24小時．但當(dāng)我們談?wù)摪滋旌秃谝�，我們使用�?天"是指日出與日落之間的時間．由于地球看起來像個球，太陽一次只能照到它的一半．總是有一半的地球是白天，另一半是夜晚．在赤道，白天和黑夜有同樣的長度．他們都有十二小時．太陽在早上6點升起，晚上6點降落．六個月，北極總是傾斜向太陽．在這幾個月北半球得到比南半球更長時間的陽光．白天比黑夜長．赤道以南夜長于白天．對于其他六個月，北極傾斜遠(yuǎn)離太陽．那么南半球得到更多的陽光．白天比黑夜長．赤道以北夜長于天．冬季是有漫長白天的季節(jié)．
解答 91．C 細(xì)節(jié)理解題．根據(jù)"we are using"day"to mean 24hours．"和"we are using"day"to mean the time between sunrise and sunset．"，可知day有兩層含義，一個是"天"，一個是"白天"．故選C．
92．B 細(xì)節(jié)理解題．根據(jù)"At the equator day and night are sometimes the same length．"可知sometimes（有時候）在赤道，白天和晚上時間一樣長．故選B．
93．A 判斷推理題．根據(jù)"For six months the North Pole is tilted toward the sun．"，聯(lián)系地理知識，可知北極傾斜向太陽，所產(chǎn)生的現(xiàn)象是南半球和北半球的黑夜，白天時間．故選A．
94．D 判斷推理題．根據(jù)"Always one half of the earth is having day and the other half night．"，可知東、西半球正好相反．故西半球是白天時，東半球就是黑夜．故選D．
95．A 判斷推理題．根據(jù)"the South Hemisphere gets more sunlight．Days are longer than nights．"，可知南半球得到更多陽光時，白天比夜晚時間長．故A正確，D選項錯誤．根據(jù)原文最后一句"Winter is the season of long nights．Summer is the season of long days．"，可知B與C選項錯誤．故選A．
點評 本題考查地理常識類閱讀．對于初中生，這些地理常識都很熟悉，會降低閱讀難度．
