However, technology is also changing the way farmers work. Mr Green has a farm in the countryside. In the past, he had to walk around his fields every day to check the plants. Now he uses small sensors in the soil. These sensors collect information about water, temperature and the condition of the soil. The information is sent to Mr Green’s phone. If the soil becomes too dry, the system tells him that the plants need water. Some machines can even water the plants automatically. In this way, farmers can save both water and time. Mr Green also uses a small drone to take pictures of his fields from the air. The pictures help him find problems with plants before the problems become serious. However, Mr Green does not believe technology can do everything. “Machines can provide useful information,” he says, “but farmers still need experience and knowledge.” Technology has made Mr Green’s work easier, but he believes the best farm needs both smart machines and smart people. 1. What did Mr Green have to do in the past? A. Take pictures every day. B. Walk around the fields to check plants. C. Use his phone to water plants. D. Ask other farmers for help. 32. What can the sensors NOT collect information about? A. Water. B. Temperature. C. Soil. D. Food prices. 33. What does the word “automatically” in Paragraph 2 probably mean? A. Without people doing it by hand. B. Very carefully. C. At a high price. D. With great difficulty. 34. Why does Mr Green use a drone? A. To carry water. B. To plant vegetables. C. To find problems in the fields. D. To send messages. 35. What is the main idea of the passage? A. Farmers should stop using traditional ways. B. Technology can help farmers work better. C. Farming is becoming more difficult. D. Smartphones are the most useful farming tools. B Imagine arriving home after a long day. Before you open the door, the lights are already on and the room is at the perfect temperature. Your fridge knows that you are running out of milk and adds it to your shopping list. Your watch even tells the house that you are tired, so it plays some quiet music. This may sound like a story about the future, but some smart homes can already do many of these things. Smart homes use devices that are connected through a network. These devices collect and share data. They can learn about people’s habits and make changes to the home. For example, a smart heating system can learn when a family usually comes home. It can then heat the house shortly before they arrive instead of keeping it warm all day. This can save energy. However, there are also concerns. Smart devices collect a large amount of information about people’s daily lives. If this information is not kept safe, other people might be able to see it. There is another problem. If too many devices depend on the Internet, a network problem may stop some of them from working. For these reasons, experts say people should think carefully before making every part of their home “smart”. Smart technology should make life easier, but people should also understand how it works and what information it collects. Perhaps the smartest home is not the one with the most technology. It is the one that uses technology wisely. 36. What does the first paragraph mainly do? A. It explains how to repair a smart home. B. It gives examples of what a smart home can do. C. It tells us why people dislike technology. D. It introduces the history of computers. 37. How can a smart heating system save energy? A. By keeping the house warm all day. B. By turning off the Internet. C. By learning when people usually return home. D. By asking people to stay at home. 38. What does the word “concerns” in Paragraph 3 most probably mean? A. Things people are worried about. B. New kinds of machines. C. Changes in temperature. D. Useful pieces of information. 39. Which of the following can be inferred from the passage? A. Smart technology never causes problems. B. Every home should use as many smart devices as possible. C. People should protect their information when using smart devices.D. Smart homes cannot save energy. 40. What does the writer want to tell us? A. We should stop using smart devices. B. Smart devices will completely replace people. C. Traditional homes are always better than smart homes.D. Technology should be used carefully and wisely. 参考答案 一、用所给词的适当形式填空 1. changes 42. smoothly 43. treatment 44. warned 45. connected 46. safer 47. payments 48. automatically 49. expert 50. easier 二、根据汉语意思写单词 1. network 52. flood 53. multimedia 54. laptop 55. data 56. company 57. traffic 58. flow 59. mobile 60. device 三、完形填空 1-5 D A C B A 6-10 D A C A B 四、阅读理解 A篇： 1.
