阅读短文，选择正确答案。    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 (旋转) 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 (倾斜) 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 night. North of the equator nights are longer than days. Winter is the
season of long nights. Summer is the season of long days. 1. When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.
