Farming started early in many places around the world.
The ancient farmers of Sumer in the Middle East used oxen (牛) for ploughing and had special methods to water their fields. These farming methods made it possible for country to have large armies in (defend) of it, which helped spread their culture.
Culture in Egypt developed for similar reasons. The Egyptians developed an
(amaze) system of watering fields from the Nile. The ability (feed) many people from very little land around the Nile helped Egypt build a large and strong country. The Egyptians' water systems were copied and developed by farmers around the world.
Crops like (tomato), beans and several other plants were developed in the West. The native people in North America used a farming method (call) "the three sisters". These three vegetables — beans, corn and squash（瓜）— are grown together,
helps the soil stay healthy. The method is still (wide) used today.
In Central America, the farmers of the Aztec culture cut large steps into the sides of their hills to get more farmland. Aztecs were most famous, however, creating "floating gardens". Wet areas around lakes couldn't (use) for farming, so Aztec farmers created islands on the edges of the lakes to grow crops on.
