It is very important to stay healthy. I have a neighbor. She is an old lady. She can do all the housework, __41__ newspapers, watch TV and search on the Internet to learn something new. I often see __42__ do taijiquan in the morning and dance in the evening. She looks young and beautiful __43__ she is over seventy. Last week a reporter from a magazine interviewed her and asked __44__ she kept so young and healthy. She replied with a smile:I have a secret of staying young and healthy. It is quite __45__ keep your mind active，take an interest in the world __46__ you, and learn at least one new thing every day. Try to do different kinds of housework and do sports as __47__ you can. Don’t think you are too old to go back to __48__. I know a man who entered a medical college when he was 70 years old. He studied there for 6 years and now he is a doctor.

　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.
