 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 I was at university,I studied very hard.But a lot of my friends did very little work.Some did just enough to pass exams.Others didn’t do quite enough.Fred Baines was one of them.He spent more time drinking in the Students’ Union than working in the library.
  Once at the end of the term,we had to take an important test in chemistry.The test had a hundred questions. In my room the night before the test,Fred was watching TV.Fred usually worried a lot the night before a test.But on that night he looked perfectly calm.Then he told me of his plan.“It’s very simple.There are a hundred questions and I have to get fifty correct to pass the test.I’ll take a coin into the examination room.I haven’t studied a chemistry book for months,so I’ll just toss the coin.That way,I’m sure I’ll get half the questions right.”
  The next day,Fred came happily into the exam room.As he sat tossing a coin for half an hour he marked down his answers.Then he left,half an hour before the rest of us.
  The next day,he saw the chemistry professor in the corridor.“Oh,good,”he said,“Have you got the result of the test?”The professor looked at him and smiled,“Ah,it’s you,Baines.Just a minute.”Then he reached into his pocket and took out a coin.He threw it into the air,caught it in his hand and looked at it.
  “I’m terribly sorry,Baines,”he said,“You failed!”
