根据短文内容，从短文后的选项中选出填入空白处的最佳选项。选项中有两项为多余选项。

     The Mayan Indians lived in Mexico for thousands of years before the Spanish arrived in the 1500s. They

had farms, beautiful palaces, and cities with many buildings. 1_____ This knowledge helped them to live a

better life than most people of that rime, because they could use it to make their life more comfortable and

rewarding.

     In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields

of corn, beans, and other crops around it. To clear the land for farms, the Maya cut down trees with stone

axes. They planted seeds by digging holes in the ground with pointed sticks. 2_____

small huts with no windows. The walls were made of poles covered with dried mud, and the roof was made

of grass or leaves. 3_____

time.

     Around the year 800, the Maya left their villages and beautiful cities, never to return. 5_____ They may
