【文章导读】中国科学家研发出全球首个能完成植物育种的机器人——GEAIR。它可以完成植物育种的全部步骤，特别是在杂交育种中能帮很大的忙。
Chinese scientists have made a smart robot called GEAIR. It is the first robot in the world that can finish all the steps of plant breeding. This is very useful for hybrid breeding(杂交育种).
Hybrid breeding helps plants grow stronger, make more food, and have better qualities. For example, Yuan Longping used hybrid breeding to make hybrid rice, which fed many Chinese people.
In hybrid breeding, workers need to take off the stamens(雄蕊) from the female plant, and then put pollen(花粉) from the male plant onto the female plant. This lets the new plant get the best parts from both parents. But this work must be done many times in a short time, so it needs a lot of time and energy.
GEAIR can solve this problem. It uses AI to find flowers, walk between plants, and use its robotic arms to do cross-pollination(异花授粉). It can finish the whole job by itself.
However, making this robot was not easy. Leaves often block the flowers, and flowers are very small, so computers cannot find them quickly. To fix this, scientists trained a new AI model with 12,800 flower pictures. Now GEAIR can pollinate one flower in 15 seconds, and it also costs much less than hiring workers.

D. It always breaks the flowers.
()3. What can GEAIR do?
A. Cook food for workers.
B. Do all the steps of plant breeding.
C. Grow flowers by itself.
D. Make new types of fruit.
()4. What technology does GEAIR use to find flowers?
A. Solar power.
B. 3-D printing.
C. AI visual recognition.
D. Voice control.
()5. What difficulty did scientists meet when making GEAIR?
A. Flowers were too small and easy to miss.
B. Robots could not walk on the ground.
C. They had no place to test the robot.
D. They didn't know how to grow plants.
