Question

The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since 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. A place is moved form day into night and from night into day over and over by the spinning(旋轉) of the earth. At the equator(赤道), day and night are sometimes the same length. They are each twelve hours long.. The sun rises at 6 in the morning and sets at 6 in the evening. For six months the North Pole is tilted(傾斜) toward the sun. In those months the Northern Hemisphere(半球) 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 Southern Hemisphere get more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

【解析】

試題分析：這篇短文主要介紹了天有兩層含義，白天黑夜的形成及其形成原因。

1.細節理解題。根據Since 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.可知由于地球看起來像個球，太陽一次只能照到它的一半�？偸怯幸话氲牡厍蚴前滋欤�另一半的夜晚。故選D。

2.細節理解題。根據A place is moved from day into night and from night into day over and over by the spinning(旋轉) of the earth.。可知一個地方從白天到晚上，從晚上到白天是通過地球的旋轉。故選C。

3. the equator(赤道), day and night are sometimes the same length.可知在赤道，白天和黑夜有時同樣的長度。故選A。

4.細節理解題。根據For six months the North Pole is tilted(傾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the Southern Hemisphere.可知六個月的北極傾斜向太陽。在這幾個月北半球（半球）會比南半球得到更多的陽光。白天比黑夜長。故選B。

5.細節理解題。根據Winter is the season of long nights. Summer is the season of long days.可知冬季夜長的季節。夏天是漫長的日子。因為中國屬于北半球，中國冬季之時，北極遠離太陽了，故選D。
