Nearly every week, we hear news about the latest successes and failures in driverless vehicles. 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 panies 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 puter-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.

Many of us dream of making all the difference—earning a lot of money. A great scientist has achieved that big success and 1 all the money to help others. Professor Nicola Curtin of the Newcastle University successfully 2 a new drug for cancer, but when the time came for her big 3 , she chose to give some of the profits away to help needy people to make their life better.
The drug Rubraca is the 4 of 30 years of research and helps people who have a gene known to lead to an increasing 5 of breast cancer. Rubraca helps target the cancerous cells so as to repair their DNA and finally 6 tumour cells(肿瘤细胞). The Newcastle University 7 rights of the medication(药物) for $40. 8 million to a company, which is a large sum of money. Instead of treating herself, Curtin used her $1.2 million share to 8 The Curtin PARP (Passionate About Realising Your Potential) Fund.
The fund 9 to help the disabled, the homeless, and anyone experiencing a disadvantage. It helps them to develop the skills to 10 difficulties so that they can get education or employment. "Those people's 11 makes me think about life. I have already had everything that I need in life but there are many people who are leading a hard life. 12 , through The Curtin PARP Fund, I want to leave a(n) 13 legacy(遗赠) by helping them master the basic skills for life. And I feel 14 of what I have done, "said Curtin.
What Curtin has done tells us that we can help others in many 15 by using our talent, and by reaching out and offering much assistance, etc.
