(课件网) Unit 6 When was it invented？ Period 4 读写综合 Spring is coming， and it’s time to enjoy West Lake Longjing tea！ Usually， we think workers will pick tea leaves by hand. But now， some Longjing tea is being picked by special workers — tea-picking robots！ In a tea garden in Hangzhou， a smart tea-picking robot invented by Zhejiang Sci-Tech University is working for the first time. “We take thousands of pictures of new tea buds（芽） and input them into the robot for it to learn. The robot uses an AI model to recognize （识别） the buds it should pick，” said Professor Chen Jianneng， member of the research team. This helps the robot find the right tea buds about 90 percent of the time. The robot’s arm pulls and then sucks（吸） up the tea buds. These buds are quickly moved into a special box. Once the robot has collected all the buds from the area it’s working at， it moves the buds from the box to a main box that holds everything it collects. The robot was made because there are not enough people to pick tea. In Zhejiang， about 400，000 pickers are needed now. “Picking is the greatest challenge for the development of the tea industry，” said Professor Wu Chuanyu， who leads the research team. ———About five years from now， the robots will do the job of picking West Lake Longjing tea instead of people，” Wu added. 一、回答问题 1.Who invented a smart tea-picking robot？ Zhejiang Sci-Tech University. 2.What does the robot use to to recognize the buds it should pick？ An AI model. 3.Where are the buds quickly moved after the robot’s arm pulls and sucks up the tea buds？ Into a special box. 4.Why was the robot made？ Because there are not enough people to pick tea. 5.According to Professor Wu Chuanyu， when will the robots pick West Lake Longjing tea in the place of people？ About five years from now. 二、精彩短语积累 1.是时候做某事 2.第一次 3.用某物做某事 4.把某物从……移到…… 5.最大的挑战 6.而不是 it’s time to do sth. for the first time use sth. to do sth. move sth. from…to… the greatest challenge instead of 三、优美句型解析 Once the robot has collected all the buds from the area it’s working at， it moves the buds from the box to a main box that holds everything it collects. 一旦机器人从它工作的区域收集了所有的茶芽，它就会把茶芽从盒子里移到一个装着它收集的所有东西的主盒子里。 【句式提炼】 once引导时间状语从句，意为“一旦”。 【句式仿写】 一旦你许下诺言，就要尽力信守它们。 Once you make promises， you should try your best to keep them. 四、句型精练 1.春天来了，是时候享受西湖龙井茶了！ Spring is coming， and West Lake Longjing tea！ 2.这有助于机器人在大约90%的时间里找到合适的茶芽。 This the right tea buds about 90 percent of the time. 3.采摘是茶业发展面临的最大挑战。 for the development of the tea industry. it’s time to enjoy helps the robot find Picking is the greatest challenge 假设你是个商人，你发明了一款机器人，你想 ... ...
