Rivers are one of our most important natural resources (资源). Many of the world's great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(运输). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(庄稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大坝) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化学物质) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.The greatest river for navigation is ___________.

Reading makes one wise，but many adults seldom read．They say they are too busy to have time to read．Sure．They have work to do．They have families to support．But these are only excuses．The fact is that they haven't got a reading habit．A reading habit isn't something natural．It needs to be trained．And it's never too late to develop a reading habit．
Scientists believe proper books are very important for children to develop a good reading habit．A book in rich colors and with simple patterns（图案） such as lines and circles is a good choice for babies of three months old．When they reach six months，they will become interested in simple story books in rich colors．
When children get old enough to read by themselves，it's necessary to buy books that are both interesting and right for them to understand．Books which are either too easy or too difficult are not good for kids to keep their reading habits．
Only buying books for children isn't enough．For kids，parents are their first teachers．So parents should read books to set an example．Children will follow them．Scientists say imitatingthe adults is a born skill．And it is the most valuable way for children to learn．This will certainly help them develop a reading habit in the end．
