The human population on Earth grows larger each year. As 1． result, some scientists carried out a research project. Because of climate change (气候变化), growing more food is 2． (become) even more difficult. When farmers 3． (try) to grow more food in the past, they would use farming methods that weren’t always healthy for the environment. 4． (solve) this problem, more and more food needs to 5． (grow) in order to feed everyone. They spent several years talking to 6． (farmer). They wanted to see what problems farmers were having and how these problems could be solved. This led to the creation of special robots. These special robots move around on farms and collect information about crops (庄稼). They can take pictures of plants, track (追踪) each plant’s growth and measure (测量) its size.

In the past, 7． farmers did have information about the weather and the earth, they couldn’t track each plant. But now, with these robots, they can.

By collecting information about plants, the robots can help farmers make predictions (预测) about 8． their plants will grow. By studying each plant, the robots can also help farmers grow plants 9． (good). For example, if the robots find out which plants get sick, farmers can quickly throw them away before they are about to influence nearby plants. With the help of 10． (this) robots, farmers can take better care of the plants in need.
