How would you like to live in a land where the sun shines day and night? There are place in the polar regions where, for North, the sun never sets! This is known as the land of the Midnight Sun. This period of sunlight can last up to six months.
This happens because the Earth tilts(倾斜). When the North Pole is tilted towards the sun, it has constant (不断) daylight. As the same time, the South Pole is tilted away from the sun. It is in darkness.
Six months later, the South Pole tilts to the sun and has constant daylight. Then the North Pole is tilts away. It has darkness.

解析

试题分析：极地地区,有极昼极夜现象。这一时期的阳光可以持续长达六个月。这是因为地球的倾斜造成的.当北极朝向太阳倾斜，就是极昼。同一时间，南极倾斜时，远离太阳。它是极夜。半年后，在南极向太阳倾斜，并具有恒定的日光。北极倾斜了。它有黑暗。
小题1:细节理解题，根据文中语句“How would you like to live in a land where the sun shines day and night? There are place in the polar regions where, for North, the sun never sets! This is known as the land of the Midnight Sun.”理解可知。在极地地区。
小题2:细节理解题，根据文中语句“This period of sunlight can last up to six months.”理解可知。极昼现象持续6个月。
小题3:细节理解题，根据文中语句“This happens because the Earth tilts(倾斜).”理解可知。极昼极夜现象是由地球倾斜造成的。
小题4:细节理解题，根据文中语句“When the North Pole is tilted towards the sun, it has constant (不断) daylight.”理解可知。当北极地区朝向太阳时那里就是极昼时间。
小题5:细节理解题，根据文中语句“As the same time, the South Pole is tilted away from the sun. It is in darkness.”理解可知。北极地区是极昼时，南极就是极夜。
