The Mayan Indians lived in Mexico for thousands of years before the Spanish arrived in the 1500s. The Mayan achievements were many. They had farms, beautiful palaces, and cities with many buildings. The Mayan people knew a lot about nature and the world around them. This knowledge helped them to live a better life than most people of that time, because they could use it to make their lives more comfortable and rewarding . Knowledge about tools and farming, for example, made their work easier and more productive. The Maya believed in many gods, including rain gods, sun gods, and corn gods. The people built large temples to honor the Mayan gods. Skillful workers built cities around these temples. It was difficult for them to build these cities, because they had no horses to carry the heavy stone they used to build with. Workers had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing. Although the cities that the Maya built were beautiful, and the people worked hard to build them, very few of the people lived in them. Usually, only the priests lived in the cities. The other people lived in small villages in the forests. Their houses were much simpler than the _ buildings in the cities. They lived in small huts with no windows. The walls were made of poles covered with dried mud, and the roof was made of grass or leaves. Most Maya lived a simple life close to nature. The Mayan priests studied the Sun, the Moon, stars, and planets. They made a calendar from what they learned. The year was divided into 18 months of 20 days each with five days left over. The Mayan calendar was far more exact than the European calendars of the time. Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from some disease. They may have left because the soil could no longer grow crops. Archaeologists are still trying to find the lost secrets of the Maya. From the passage we can infer that _ . A) most Maya lived in beautiful cities B) many Mayan cities and temples are still standing C) the Maya were intelligent and culturally rich people D) the Mayan calendar was the same as European calendars

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 part in the lives of its people. Since the beginning of 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 Ganges 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 southeastern 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 up it. Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun. In order to increase the supply of water for crops, engineers sometimes build a dam across a river and let a lake form 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 on rivers often cause 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 these natural resources. When rivers are dammed, people use the water for _ . A) keeping the rivers clean B) making electricity C) washing clothes D) irrigation and the production of electricity
