But we hear little about how other industries are developing this same kind of technology.One industry heavily involved in researching and developing artificial intelligence, or AI, is agriculture. Companies are experimenting with high-tech tools that can help farmers save time and money, while reducing environment-harming chemicals.One of the companies is ecoRobotix of Switzerland. It created a robot equipped with AI and cameras to identify all plants on a farm. The robot has four wheels to carry it through the fields in search of weeds. Computer-controlled arms then lower and spray the weeds with small amounts of herbicide (除草剂). Company officials say the robot can fully operate on its own for up to 12 hours a day while being powered by the sun. It uses the same kind of sensor and positioning technology used to guide driverless vehicles. A farmer can also control the equipment through a smartphone.The co-founder of ecoRobotix, Aurelien Demaurex, says the farm robot can kill weeds with 20 times less herbicide than traditional methods. This is because the system uses exactly the right amount of chemical in the exact place required to kill the weeds. Currently, farmers spread weed killers over massive areas to destroy unwanted plants.Another company developing farm robotics is California-based Blue River Technology. The company has a system called "See & Spray", which it claims is the world's first smart sprayer. The system—which connects to the back of a tractor—is also equipped with AI to identify and chemically kill only the weeds. It can also spray chemicals on wanted plants to help them grow. Ben Chostner, vice-president of business development for Blue River Technology, explains in a company video that "See & Spray" technology uses the same deep learning methods used in facial recognition. "The first time the machine saw a pigweed, it didn't know what kind of plant it was. But we taught it—by giving it tens of thousands of examples of pigweed—and now it's an expert in pigweed."1.How will AI benefit agriculture?A.It will fund agriculture research.B.It contributes to low-cost farming.C.It can avoid harmful chemicals.D.It frees all farmers from field work.2.What do the products of the two companies have in common?A.They use recognition technology.B.They are powered by solar energy.C.They are connected with smart phones.D.They can help wanted plants grow rapidly.3.What do Ben Chostner's words suggest about the robot?A.It is environmentally friendly.B.It is good at self-improving.C.It has the learning ability.D.It can track various plants.4.What is mainly talked about in the text?A.The experiment in farming robots.B.New trend in artificial intelligence.C.Modern "See & Spray" technology.D.Artificial intelligence in agriculture.三.阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
