Jane Harper.BCatherine Yeo was three years old when she discovered Sudoku(数独) puzzles at the back of magazines and newspapers. She would compete against her mother to see who co

12、uld fill in the empty cells in the shortest time, often defeating her mother. Soon she developed an interest in math and technology.The 16-year-old from San Jose is currently in her second year at Stanford Online High School, unique for its virtual environment. “Many of my classmates live across the

13、 globe, so its fascinating to hear diverse viewpoints during our class discussions,” says Yeo. The courses at her school are extremely challenging, but being at an online school allows her to have time to carry out her own projects. Now, Yeo is leading Pixelhacks, a 24-hour hackathon(编程马拉松) for fema

14、le high school students.Yeo had never seen a mens bathroom line five times longer than the womens bathroom line until she attended the Apple Worldwide Developers Conference (WWDC) in 2016. In other public places like airports, theaters and restaurants, it was always the opposite. The great gender ra

15、tio (性别比例) difference opened her eyes. “Most computer science classes and robotics teams only had a few girls and the hackathons I attended were occupied by male students,” says Yeo. Out of every 200 hackathon attendees, only an average of 15 percent were female. Yeo had helped with local Girls Who

16、Code clubs and organized free coding (编程) workshops at a public library for middle school students. But WWDC made her realize that wasnt enough. She took action to introduce many girls in her community to the fun, creative side of technology. Eight months later, she stood in front of over 70 young w

17、omen who were eager to learn to create applications.For two years, Yeo organized Pixelhacks, Northern Californias first all-female high school hackathon where attendees(在场参与者) work together to create a technology project in a limited amount of time. Yeo founded it to expose girls to technology and h

18、elp them build confidence and acquire fundamental skills. She invited female industry experts to teach all attendees and speak about their experiences. Yeo marketed the event to high schools across the San Francisco Bay Area, especially low-income schools. Right after Pixelhacks I, Yeo saw many fami

19、liar faces from Pixelhacks I at other local hackathons and tech events. A mother of a Pixelhacks II attendee said she had hoped her daughter could meet new friends and develop an interest in computer science at Yeos hackathon. After the event, she was shocked to hear that her daughter decided to mak

20、e a career in programming.Being able to observe the influence of her work on so many girls and seeing their interest in computing and technology grow is Yeos proudest achievement, Yeo strongly believes that all women are equally talented in technological abilities. The problem of the great gender in

21、equality(性别不平等) lies in the lack of exposure to programming and engineering for many young women. Having access to opportunities to learn about technology can greatly increase a young womans interest and confidence in her skills. “its also extremely important to find your teachers and community,” sa

22、ys Yeo. “Im extremely grateful for the many women in the computer industry who have helped me with my project.”24. What does Catherine Yeo like about her school?A. Its focus on technology. B.

24、for them to find qualified teachers.B. They have no interest in technology.C. Limited opportunities are offered to them.D. They are usually poor in mathematics.27.

25、voted to technical projectsC. There is a gender inequality in the tech industryD. This 16-year-old started her own hackathon for girlsCSkyscrapers(摩天大楼) are the symbol of urban life. City people are used to seeing tall buildings and apartments. Farms, on the other hand, are associated with rural(农村的

26、) life. However, there are experts who think skyscrapers should become farms to meet the increasing food needs.By the middle of this century, some scientists suggest, almost 80% of the earths population could live in cities. In addition, the population could increase to 9.1 billion people during tha

27、t time yet the amount of land available for farming will be the same. If current farming practices dont change, we will need an area of new land to produce enough food for the planet.Vertical(垂直的) farms, where urban farmers could grow crops in environmentally friendly skyscrapers, could be the solut

28、ion. In spite of concerns over high costs, experts want to make it a reality and use these skyscrapers to grow crops.Vertical farms would have many advantages, supporters say. Unlike traditional farming, vertical farming could be free of chemicals and diseases. Besides, crops would not suffer from p

29、roblems like flooding. Finally, vertical farms would reduce the cost and negative effects of transporting food over long distances.Some argue that although crops growing in a tall glass building would get natural sunlight during the day, it wouldnt be enough. For this reason, vertical farms would ne

30、ed additional light sources(来源), such as artificial light.Another way of growing fresh food is to build urban farms on rooftops. This more practical approach may be more achievable than the idea of farms in skyscrapers, researchers suggest. Experts agree that innovative(革新的 ) farming practices are n

31、eeded to support the need for more food at affordable costs, both to the farmer and to the consumer, but the best ideas could be yet to come.28. What primary problem could vertical farming settle?A. Poor state of rural life.B. Shortage of food supply.C. High cost for transporting crops.D. Environmen

32、tal pollution by transitional farmings.29. What is the advantage of vertical farming?A. It can produce organic food.B. It requires little care.C. It can benefit transport industry.D. It needs very low cost.30. What is a big challenge to make vertical farming a reality?A. Farmable land. B. Crop disea

33、ses.C. Light sources. D. Climate conditions.31. What can be the best title of the test?A. Future Food NeedsB. Symbol of Urban LifeC. Farming on RooftopsD. Farms of the FutureDNearly every week, we hear news about the latest successes and failures in driverless vehicles. But we hear little about how

34、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 che

35、micals.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 herbi

36、cide(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 smart-phone.The co-founder

37、of ecoRobotix, Aurelien Demaurex, says the farm robot can kill weeds with 20 times 1ess 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

38、 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 was the worlds first smart sprayer. The system which connects to the back of a tractor(拖拉机) is also equipped with AI to identify

39、 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.

40、 “The first time the machine saw a pigweed, it didnt know what kind of plant it was. But we taught it by giving it tens of thousands of examples of that pigweed and now its an expert in pigweed.”32. How will AI benefit agriculture?A. It will fund agriculture research.B. It contributes to low-cost fa

41、rming.C. It can avoid harmful chemicals.D. It frees all farmers from field work.33. 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.34.

42、What do Ben Chostners 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.35. What is mainly talked about in the text？A. The experiment in farming robots.B. New trend in artificial intelligence.

43、C. Modern See & Spray technology.D. Artificial intelligence in agriculture.第 二 节 (共 5 小 题 ； 每 小 题 2 分 ， 满 分 10 分 )根 据 短 文 内 容 ， 从 短 文 后 的 选 项 中 选 出 能 填 入 空 白 处 的 最 佳 选 项 。 选 项 中 有 两 项 为 多 余选 项 。Mary went through a personal experience 40 years ago that changed her life path and established her connec
