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 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.

Zhalong is a nature reserve in Heilongjiang in north-east China. It is one of the world’s most important wetlands. The reserve covers an area of 210,000 hectares. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.
Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.
Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.
