By ten o’ clock in the evening, it had only cooled down to 31degrees, according to Larry's thermometer in the living room. Larry had two table fans in his bedroom. Because of the high temperature, the last three evenings had been“two-fan” nights. He used his air conditioner only occasionally. During one month last summer, he had used the air conditioner for 10 days continuously, day and night. His electric bill that July, normally about $30, was $77. But Larry thought that, once in a while, using the air conditioner wouldn't kill him. So that evening at 11:30, just before he went to bed, he turned on the air conditioner. He set 24 degrees. He woke up four hours later when he heard a big bang, which sounded like two cars had run into each other on the street outside. But it wasn't two cars. It was a noise from the air conditioner box on the top of the house. And his air conditioner stopped. When he turned on the air conditioner again, it didn't work. Larry believed there was something wrong with his air conditioner. At once,he called Jack, the repairman. When Jack came the next day, he climbed up to the top of the house. Twenty minutes later Jack told Larry, “You need a new air conditioner. Yours is the oldest and lasted the longest in this apartment building. You need a new one, but it's going to cost $1,200.” “Wow,” Larry said, but he wondered if he should drive to the store to look for a third fan for his bedroom. ( )1.

At the end of March, Hangzhou welcomed its best period of large-scale(大规模的) harvesting of West Lake Longjing tea. In one tea garden, a smart tea-picking robot invented by Zhejiang Sci-Tech University first appeared in public after five years of research and development. With a pull and a suck(吸), the robotic arm separates the leaves from the trees and then puts them into a storage box quickly.“The robot learned its skills through a specially designed model that offers it a large amount of information of tea leaves,” said Chen Jianneng, one of the researchers.“This allows the robot to recognize tea leaves by itself with a success rate(成功率) of over 90 percent,” Chen added. Yet, the robot's picking system needs improving before it can be more widely used. According to Professor Wu Chuanyu, leader of the research team, the robot can only take on the work of 1.5 workers at present. It will need to do the work of 5 workers if it is used for a large-scale harvesting. In addition,the robot can now only be used on flat ground, not on rough(崎岖不平的) surfaces such as mountains.It may take five more years to realize these goals, Wu told China News. Tea planting and processing are also changed to become“smarter”. For example, there are special lamps that can attract pests(害虫) but will not hurt other“friendly” insects. This machine works for 24 hours, using colour board and lights to draw pests in day and night and then kill them with an electric grid(电网). In terms of tea roasting(炒制), although machine-roasted tea is used widely, many tea lovers argue that this method will make the tea not have the same taste with the tea made by hand-roasting.Researchers at Zhejiang University are trying to find out the tiny differences between the two methods to improve machine performance. They' re researching AI technologies to help them gain necessary information and make adjustments(调整) to roasting methods and temperatures in time. When Tea Meets New Technology Thanks to the researchers’ hard work for development, a small tea-picking robot made its first 1 in public to help human workers harvest West Lake Longjing tea. Tea-picking How does the robot pick tea leaves? ● 2 more than enough information about tea leaves. · Recognize tea leaves 3 any help with a high success rate. • Separate the leaves from the trees and put them into a storage box with a pull and a suck. What problems does the picking system have? It may take 4 five years to improve the picking system of the robot before it can be more widely used. ●At present, the robot can only do the work of 1.5 workers. · In addition, the robot can't be used on different kinds of 5 . Tea planting and processing · The machine 6 colour board and lights to attract pests for 24 hours, and then kills them with an electric grid. Tea roasting · Problem Many tea lovers think the machine-roasted tea will have a 7 taste from hand-roasted tea. · Solution Find out the tiny differences between the two methods. Gain necessary information and make adjustments in time with the 8 of AI technologies. Your ideas What are the advantages of using robots to replace human labour in tea industry? 9 Welcome to the unit 一、1.

D 词义猜测题。根据上文“Because of the high temperature, the last three evenings had been‘two-fan’ nights.”及下文“During one month last summer, he had used the air conditioner for 10 days continuously...”可知,今年 Larry因为高温,最近三天晚上都是用两台风扇降温，并且去年在炎热的夏季，他一个月只连续使用空调10天。由此可推知，他只是偶尔用一下空调。 2. C 推理判断题。根据第三段中“So that evening at 11:30, just before he went to bed, he turned on the air conditioner.”及 He woke up four hours later when he heard a big bang可知, Larry是在11:30睡觉前开的空调，四小时后空调坏了。由此可推知，空调在凌晨3：30的时候坏了。 3. B推理判断题。从文章最后一段中 he wondered if he should drive to the store to look for a third fan for his bedroom可知,他想知道是否应该开车去商店再买一台风扇。既然他打算再买一台风扇，那么他应该没有考虑买新空调。 4. B 细节理解题。从第二段中“His electric bill that July, normally about $30, was $77.”可知,通常情况下他每月的电费大约是30美元，除了去年七月份电费是77美元。 六【语篇导读】本文讲述了西湖龙井茶的采摘、种植和加工过程中新技术的应用。 1. appearance 提示:根据第二段中“In one tea garden, a smart tea-picking robot invented by Zhejiang Sci-tech University first appeared in public after five years of research and development.”可知,在某茶园,智能采茶机器人经过五年的研发首次公开亮相。Make one's first appearance 表示“首次亮相”,故填appearance。 2. Offer 3. without 4. another 提示:根据第四段中“It may take five more years to realize these goals...”可知,实现这些目标可能还需五年时间，five more years 可转换成 another five years,故填 another。 5. surfaces 6. uses 7. different 8. help 提示:根据最后一段中“They' re researching AI technologies to help them gain necessary information and make adjustments to roasting methods and temperatures in time.”可知,他们正在研究在人工智能技术的帮助下，获得必要的信息，并及时调整烘烤方法和温度，with the help of 表示“在……的帮助下”,故填help。 9. Robots can improve tea industry efficiency with precise harvesting, lower labour costs, and consistent, high-quality processing from field to packaging.(言之有理即可) 学科网（北京）股份有限公司 $
