Chinese scientists have recently developed the world's first intelligent robotic plant breeder called GEAIR. It can finish all the steps of plant breeding. This is very important for hybrid breeding.
Hybrid breeding helps plants grow stronger and make more food. Yuan Longping made hybrid rice, and this rice has fed many Chinese people. According to Cell Press, the hybrid breeding process usually needs workers to take off the stamens(雄蕊) from the female plant first. Then they put pollen(花粉) from the male plant onto the female plant. This way, the new plants can get the best parts from both parent plants. For example, if you mix a male plant that doesn't get sick easily with a female plant that makes lots of fruit, you can get a new plant that has both of these good things.
But hybrid breeding needs workers to do cross-pollination(异花授粉) over and over again in a short time. This work takes lots of time and energy.
GEAIR fixes(解决) this problem. It uses AI visual recognition and positioning(定位) technology to walk between crops. When it finds flowers, it uses robotic arms to do cross-pollination and finish all the work.
Making the robot was not easy. Leaves stand in the way, and flowers are very small. Traditional computer algorithms(算法) can't find them easily in real time. To solve this, the research team trained a new model with 12,800 flower pictures.
With this model, GEAIR can pollinate each flower in 15 seconds. And the cost is much lower than a worker's yearly pay.

()1. What can we know about GEAIR from the passage?
A. It is less efficient than manual work.
B. It can only be used for hybrid rice breeding.
C. It was made without any technical difficulties.
D. It saves more time and money than workers.
()2. Why could GEAIR solve the problem that traditional computer algorithms couldn't?
A. Because it uses much bigger robotic arms.
B. Because it doesn't need to walk between crops.
C. Because it only works in places with no leaves.
D. Because the team trained a new model with flower pictures.
()3. 新考法·行文方式 Which way does the writer use to show the importance of hybrid breeding?
A. Giving examples.
B. Asking questions.
C. Comparing numbers.
D. Describing feelings.
()4. What is the best title for the passage?
A. Yuan Longping and the hybrid rice
B. The difficulties of traditional hybrid breeding
C. The world's first intelligent breeding robot
D. The way of cross-pollination in plant breeding

中国科学家研发出全球首个能完成植物育种全流程的机器人GEAIR,可解决杂交育种异花授粉耗时耗力的问题。
1. D 推理判断题。由“... GEAIR can pollinate each flower in 15 seconds. And the cost is much lower than a worker's yearly pay.”可知,GEAIR可以在15秒内为每朵花授粉,而且成本远低于工人的年薪,因此相比工人,它更节省时间和成本。
2. D 细节理解题。由“To solve this, the research team trained a new model with 12,800 flower pictures.”可知,为解决这一问题,研究团队用12 800张花朵图片训练了一个新模型。
3. A 行文方式题。在第二段中,作者强调“杂交育种有助于植物生长得更强壮并产出更多的食物”,然后举例说明。
4. C 标题概括题。由全文内容可判断,作者主要介绍了世界上第一个智能育种机器人。
