Because of climate (气候) change, this task is becoming even 93 than before. In the past, many farming methods 94 by farmers to grow more food. However, those methods weren’t always 95 for the environment. In fact, they were harmful sometimes.
To solve this problem, some scientists set up a research project. They spent several years talking to farmers. They wanted 96 what problems farmers were having and how these problems could be solved. This led to the 97 of special robots. These special robots move around on farms and collect information about plants. They can take 98 of plants and record each plant’s growth.
By collecting information about plants, the robots can help farmers predict the growth of the plants. By studying each plant, the robots can also help 99 look after plants better. For example, if the robots find out which plants get sick, farmers can 100 throw them away before they are about to influence other plants. If farmers make full use of these robots, the plants 101 better. We believe that the robots will play an important role in solving the problem of food shortage (短缺) in the world.

So students can spend less time on what they 148 so far and study what they need to learn. With the help of AI, students can get scores 149 after an online test.
AI also studies students’ needs and then prepares personalized materials for them. In this way it can help students learn better by 150 .
Besides, AI makes teachers’ work easier. AI can do boring work like grading papers. This stops teachers from doing the simple work 151 , and spares a lot of time for teachers to give good lessons and talk with students face to face.
With the help of AI, both teachers and students can enjoy learning more and achieve better results together.
