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(长度). 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(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 nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.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 |
A place is moved from day into night and from night into day over and over by _______________ of the earth.

Napoga is a 12-year-old girl in Ghana(加纳),Africa.It is hard for her family to get clean water.Every morning,she leaves home at half past five to get clean water for her family from a village far away.It takes her six hours to get enough clean water for daily(日常的)cooking and drinking.She has no time to go to school or to play with her friends.Millions of people in the world are like Napoga.They can’t get enough clean water to keep healthy.
Earth Day is April 22.But on all other days,we must also remember it.The water we use is the most important natural resource(自然资源)on the earth.
Water covers 70% of the earth’s surface(表面).But most of that is sea water.We can’t use it for many things.Fresh water covers only 1% of the earth’s surface.
You probably feel lucky that your life isn’t as hard as Napoga’s.But that doesn’t mean you don’t have to worry about water.We all face serious water problems.One of them is water pollution.All kinds of things from cars,factories,farms and homes make our rivers,lakes,and oceans dirty.Polluted water is very bad for people to drink.And dirty water is bad for fish,too.Now,34% of all kinds of fish are dying out.
How do cars and factories make our water dirty?First,they pollute the air.Then,when it rains,the rain water comes down and makes our drinking water dirty.Dirty rain,called acid rain(酸雨),is also bad for plants,animals and buildings.
Scientists say that in 30 years,more than half of the people in the world won’t have enough clean water.We have to learn how to save more water for ourselves and our children.Here is some advice for saving water:
● Turn off the water while you brush your teeth.You can save as much as 450 liters(升)each month.
● Leaky taps(漏水的水龙头)waste a lot of water.Fix them right away!
● You can easily cut your 10-minute showers(沐浴)in half—and you’ll be just as clean.
● When you wash dishes,don’t let the water run.
● Only wash clothes when you have a lot to wash.If your washing machine isn’t full,you’re wasting water!Every morning Napoga went to get clean water________.
