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 from day into night and from night into day over and over by the spinning（旋轉(zhuǎn)）of the earth. At the equator（赤道）day and night are sometimes the same length（長度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock 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 gets 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.
（  ）6.When the Western Hemisphere is having day, the Eastern Hemisphere is having ________.
　　     A. both day and night              B. day
　　     C. neither day nor night            D. night
（  ）7. A place is moved from day into night and from night into day over and over by ________ of the earth.

（  ）8. At the equator day is as long as night ________.
　　        A. sometimes     B. never       C. usually        D. always
（  ）9. When the North Pole is tilted toward the sun, the Northern Hemisphere gets ________ sunlight.
　　    A. less           B. more       C. all            D. no
（  ）10. When it is winter in China,  ________.
　　    A. the USA is tilted toward the sun
　　    B. the South Pole is tilted away from the sun
　　    C. the North Pole is tilted toward the sun
　　    D. the North Pole is tilted away from the sun

Answer 1

【小題1】D
【小題2】C
【小題3】A
【小題4】B
【小題5】D

解析【小題1】細(xì)節(jié)理解題，根據(jù)文中語句理解可知。當(dāng)東半球是白天時，西半球是黑夜，故選D。
【小題2】細(xì)節(jié)理解題，根據(jù)文中語句“A place is moved from day into night and from night into day over and over by the spinning（旋轉(zhuǎn)）of the earth.”理解可知。晝夜的交替是由地球的自轉(zhuǎn)造成的。
【小題3】細(xì)節(jié)理解題，根據(jù)文中語句“At the equator（赤道）day and night are sometimes the same length（長度）. They are each twelve hours long.”理解可知。赤道的晝夜長度是一致的。
【小題4】細(xì)節(jié)理解題，根據(jù)文中語句“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.”理解可知。當(dāng)北極點對向太陽時，北極地區(qū)獲得的陽光要多些。
【小題5】細(xì)節(jié)理解題，根據(jù)文中語句“For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight.”理解可知。當(dāng)中國是冬天時，南半球傾向太陽光，北極點遠(yuǎn)離太陽，故選D.
