Article: Rivers are one of our most important natural resources . Many of the world's great cities are located 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 . 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 , 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 , and chances for fun and entertainment for the people who live along their banks. In order to increase the supply of crops, engineers sometimes build a dam across a river and let a lake from behind the dam. Then people can use the water not only to irrigate 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 and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of this natural resource. Question: The best title of the passage is _ .

Article: It is very normal for people to compare themselves with others. Everyone does it, but it is important to remember that no one is perfect. Other people may look confident, but everyone feels insecure once in a while, even the famous people like Yao Ming. When he was young, he probably felt insecure about being too tall! Other kids in his class probably laughed at him because he was different, although I don't know if I would have laughed at Yao Ming since he is so much bigger than me! Now, Yao Ming is rich and successful because of his height. When I was young, I had a friend named Annie. Everyone used to call her "toothpick" because they thought she was too thin. Now, everyone is jealous of her because she is thin and beautiful, and they have to always exercise to keep from getting fat.
