One day, they were having a meal together. Uncle Arjun ate with a spoon, but the food kept 4 off the spoon and onto his clothes. He was sad about it. Instead of simply watching, Andy wanted to do something to help. Andy 5 interested in robots since he was a child. In their small house, there 6 a corner full of his robot models and tools. Andy looked at the tools and thought, “All of these models are 7 . It’s time to make one for my uncle.” As he started, his uncle smiled and said, “ 8 careful with the tools.” His words always supported Andy.   Finally, Andy made a smart spoon. The spoon is very stable (稳定的) and easy to clean. Andy has made the spoon 9 than the usual ones, so it can hold more food. Andy plans to sell his product for about 80 dollars. He is still working on cutting costs to make it even cheaper.

He was not a 2 (luck) child because he had to leave school at an early age. However, he never stopped learning by 3 (he). He read many books and did thousands of 4 (experiment). His most famous 5 (achieve) was the invention of the electric light bulb. But before he succeeded, he failed more than 1,000 times. Some people asked him if he felt 6 (disappoint) about these failures. Edison replied, “I have not failed. I’ve just found 1,000 ways that won’t work.” This is the 7 (true) of a strong mind — never giving up. Today, we still remember Edison as one of the 8 (great) minds in human history. 【答案】1．inventors 2．lucky 3．himself 4．experiments 5．achievement 6．disappointed 7．truth 8．greatest 【导语】本文介绍发明家爱迪生的人生经历，讲述他年少辍学仍坚持自学、上千次试验发明电灯，永不放弃的强大意志被后人铭记。 【详解】1．句意：托马斯·爱迪生是历史上最伟大的发明家之一。固定结构one of + 可数名词复数，invent对应的职业名词inventor，复数形式inventors。 2．句意：他不是一个幸运的孩子，因为他很小就辍学了。修饰名词child，使用形容词，luck的形容词形式lucky。 3．句意：但是他从来没有停止自学。固定搭配learn by oneself，表示“自学”，主语为he，反身代词为himself。 4．句意：他阅读大量书籍，完成了数千次实验。thousands of后面接可数名词复数，experiment变为experiments。 5．句意：他最著名的成就是电灯的发明。形容词most famous后接名词，achieve对应的名词achievement。 6．句意：有人问他是否对这些失败感到失望。feel后接修饰人的形容词，disappoint变为disappointed。 7．句意：这就是强大意志的真谛——永不放弃。定冠词the后面接名词，true对应的名词truth。 8．句意：时至今日，我们依然将爱迪生视作人类历史上最伟大的智者之一。one of + the + 形容词最高级，great的最高级greatest。 Part 1: Read the passage and answer the questions.

Everyone looks real in 3D．” Although this is a quick show, the “digital twin” can do many tests in the digital world without affecting anyone in the real world. This signpost can turn around to show you the way after you choose the destination on the screen. Building a smart park How can technology make parks smart? You can look up places on a screen (屏幕), and the signposts beside the screen can turn around to show you the direction. Street lights with sensors (传感器) will alert (提示) you if you are too close to water areas. You can even sit on solar-powered (太阳能的) benches that can play music while charging (给……充电) your phone. Planting with the press of a button   China Telecom brought a “smart” planting rack (种植架). The plants grow in small boxes on the wall. The whole system (系统) is connected to 5G, which makes it easy to control (控制) from faraway places. You can change the light and water the plants through an app. “This is made for teenagers. Users can find all kinds of environmental information (环境信息) in the app. So young people can better learn how plants grow,” said a China Telecom staff member.   By XU ZHAOLIN, 21st Century Teens 1．When did the seventh WIC end? __________________________________________________________________________________________ 2．What can the “digital twin” do? __________________________________________________________________________________________ 3．What can we do if we get lost in the smart park?   __________________________________________________________________________________________ 4．Who is the “smart” planting rack made for? __________________________________________________________________________________________ 5．How can users take care of plants in the “smart” planting rack? __________________________________________________________________________________________ Part 2: Creative Task Suppose you are going to introduce the cool inventions at the 7th World Intelligence Congress to your classmates.
