There, you can learn about great inventions and their inventors. The exhibition will take place at the City Museum. It starts on 1 May and ends on 30 May, from 9 am to 5 pm.Tickets cost £30 for adults and £15 for students. Children under 12 are free. One exciting event is a talk by inventor Mary Brown.You can learn all about the qualities of a successful inventor. It starts at 10:30 am on the first day.Young inventors, remember to come! 主持人：意想不到的发明展将于下周开幕！在那里，您可以学到许多新知识。 展览将介绍伟大的发明及其发明者。展览将在城市博物馆举行，时间从5月1日开始，至5月30日结束，每天上午9点至下午5点开放。成人票价为30英镑，学生票价为15英镑。12岁以下的儿童可免费入场。 一个令人兴奋的活动是发明家玛丽·布朗的演讲。你可以在那里全面了解一个成功发明家的素质。演讲将在第一天上午10:30开始。年轻的发明家们，记得来哦！ Do you want to be an inventor? What does it take to become an inventor? Today, let me tell you something about it. First, you need to think widely. Spencer Silver once invented a type of glue. But sadly, it was too weak. Later, Arthur Fry learnt about it and found it perfect for sticking notes to books. He used the glue in a new way, and now we have the Post-it note! Next, never stop trying. The Wright Brothers faced many failures to invent the plane. But they learnt from the mistakes and never lost hope. Thanks to them, we can travel quickly. Finally, sometimes you just need some luck. One winter night, a boy left a glass of juice outside with a stick in it. The next day, he found that the drink was frozen. He pulled it out and tasted it. That was the invention of the ice lolly! 你向往成为一名发明家吗？那么，成为发明家需要具备哪些条件呢？今天，就让我来为你讲述一些相关信息。 首先，你需要广泛思考。斯宾塞·西尔弗曾发明了一种胶水。但不幸的是，这种胶水太弱了。后来，阿瑟·弗莱得知了这种胶水，发现它非常适合用来在书本上贴便条。弗莱以全新的方式使用了这种胶水，于是我们有了便利贴！其次，永远不要放弃尝试。莱特兄弟在发明飞机的过程中遭遇了多次失败，但他们从错误中汲取了教训，从未丧失希望。多亏了他们，我们才能快速旅行。最后，有时候你只是需要一点运气。一个冬日的夜晚，一个男孩将一杯果汁放在户外，里面插了一根吸管。第二天，他发现这杯饮料已经结冰了。他将其取出并尝了尝，这就是冰棍的发明由来！ 听力原文和译文 六、作文My Favorite Invention My favorite invention is the 3-D printer. It was invented many years ago, but it's still changing our life. 3-D printers can create many useful objects, like toys, tools, and even artificial body parts for people in need. I like it because it shows how creative people can be. It also helps students like me make science models easily. I think 3-D printing will make the world more wonderful in the future. 我最喜欢的发明 我最喜欢的发明是3D打印机。它多年前便被发明出来，但至今仍在改变着我们的生活。3D打印机可以制造许多有用的物品，例如玩具、工具，甚至能为有需要的人制作人造身体部位。我喜欢它，因为它展现了人类无限的创造力。它也能帮助像我这样的学生轻松制作科学模型。我认为，3D打印技术将在未来让世界变得更加美好。 $
