The human population on earth grows larger each year. As a result, more and more food needs to be grown in order to feed everyone. This need has
1 (great) increased over the past ten years.
Because of climate change, growing more food is becoming even
2 (difficult). When farmers tried to grow more food in the past, they would use farming ways that weren't always good
3 the environment. To solve this problem, some scientists carried out a research project. They spent a few years talking to farmers, including those from the
4 (centre) areas of many countries. They wanted to see what problems farmers were having and how these problems could
5 (solve). This led to the creation of special robots. These special robots move around on farms and collect information about crops. They can take pictures of plants, record each plant's
6 (grow) and measure its size.
In
7 past, farmers had some information about the weather and soil conditions, however, they couldn't track each plant. Now with these robots, they can. Some farmers in
8 (south) villages have already started using these robots and seen good results.
By
9 (collect) information about plants, the robots can help farmers make predictions (预测) about how their plants will grow. By studying each plant, the robots can also help farmers grow plants well. For example,
10 the robots find out which plants get sick, farmers can quickly throw them away before they influence nearby plants. With the help of these robots, farmers can take better care of the plants in need.
