问题     Perhaps it is time for farmers to put their feet up now that robots are used to inspect crops, dig up weeds, and even have become shepherds, too. Commercial growing fields are astronomically huge and take thousands of man-hours to operate. One prime example is one of Australia’ s most isolated cattle stations, Suplejack Downs in the Northern Territory, extending across 4,000 square kilometers, taking over 13 hours to reach by car from the nearest major town—Alice Springs.
    The extreme isolation of these massive farms leaves them often unattended, and monitored only once or twice a year, which means if the livestock falls ill or requires assistance, it can be a long time for farmers to discover.
    However, robots are coming to the rescue.
    Robots are currently under a two-year trial in Wales which will train " farmbots" to herd, monitor the health of livestock, and make sure there is enough pasture for them to graze on. The robots are equipped with many sensors to identify conditions of the environment, cattle and food, using thermal and vision sensors that detect changes in body temperature.
    " You’ ve also got color, texture and shape sensors looking down at the ground to check pasture quality," says Salah Sukkarieh of the University of Sydney, who will carry out trials on several farms in central New South Wales.
    During the trials, the robot algorithms (算法) and mechanics will be fine-tuned to make it better suited to ailing livestock and ensure it safely navigates around potential hazards including trees, mud, swamps, and hills.
    "We want to improve the quality of animal health and make it easier for farmers to maintain large landscapes where animals roam free," says Sukkarieh.
    The robots are not limited to herding and monitoring livestock. They have been created to count individual fruit, inspect crops, and even pull weeds.
    Many robots are equipped with high-tech sensors and complex learning algorithms to avoid injuring humans as they work side by side. The robots also learn the most efficient and safest passages, and allow engineers and farmers to analyze and better optimize the attributes and tasks of the robot, as well as provide a live stream giving real-time feedback on exactly what is happening on the farms.
    Of course, some worry lies in replacing agricultural workers. However, it is farmers that are pushing for the advancements due to ever-increasing labor vacancies, making it difficult to maintain large-scale operations.
    The robots have provided major benefits to farmers in various ways, from hunting and pulling weeds to monitoring the condition of every single fruit. Future farms will likely experience a greater deal of autonomy as robots take up more and more farm work efficiently.
What may farmers be able to do with robots appearing on the farming scene?
选项 A、Upgrade farm produce.
B、Enjoy more leisure hours.
C、Modify the genes of crops.
D、Cut down farming costs.
答案B
解析 细节题。原文第一段第一句指出，因为机器人已经被用来监测庄稼、除杂草，甚至还变成了牧羊人，农民们是时候休息一下了。由此可知，随着机器人在农场上的运用，农民可能会有更多的闲暇时光，B项对应原文中的put their feet up(休息)，故答案为B。A、C、D三项原文均未提及，故排除。
