New Material as Strong as Steel but Light as Plastic

Building a house is a lot of work. There are a lot of materials you need to use. You need heavy materials like wood, bricks, and steel! All of these things help make a house sturdy and strong. But they're so heavy! 蓋房子要用到木頭、磚塊，還有鋼鐵。這些材料可以讓房子更堅固，但是它們很重！ But if these materials were too thin and too light, they probably would not be very strong. Then, the house would fall down. 如果材料太薄或太輕，房子就很容易倒。 But hey, did you know that some really smart scientists invented a new material that is super strong, but also very light? These scientists say this new material they invented is as strong as steel, but as light as plastic. Isn't that amazing? 科學家發明了一種材料，跟鋼鐵一樣堅固，但是像塑膠一樣輕。 It can also be used for a lot of different things. It can be used in cars, to help make them strong and safe to ride in. It can also be used to build strong bridges. 它可以用來做車子或是造橋。 I can't believe something as light as plastic could be used to build a strong and sturdy bridge, but these scientists say it is possible! In fact, they say this material is so strong, it is actually stronger than bulletproof glass! 科學家說這種材料比防彈玻璃還要堅固！ Wow, I hope people start using more of this material soon. That would make building houses so much easier! ________________________________ Vocabulary 這究竟是什麼新材料，真讓人好奇! 1. Material 材料。 I'm going to buy materials for the tree house. 我要去買樹屋的材料。 A tree house?
