Hi Sue. Hi Mike, so what happened to you last week?Oh, I was sick with the flu. What's this I hear about a big assignment we've got to do?Well, basically, we've got to find two science experiments to do with a group of eight-year-old children at the local primary school,and we've got to complete it by the end of the week.Oh, that sounds like hard work. Where are we supposed to get the ideas for these experiments from?Well, I managed to get hold of two books from the library. Oh, well done!How about if we take a look at the experiments in this book first and see if anything looks suitable?I can make notes as we go, about equipment and the purpose of the experiments.OK, let's see, um, the first experiment is called 'Make your own hovercraft', which sounds very ambitious!Mind you, you only need twenty balloons and a table - you don't need any special engines or anything like that!What do you do with it all?Er, you blow up the balloons and you balance the table on them, upside down of course, and the kids get to ride around on it.You know, the other kids sort of push them around the room.The main purpose is to show how hovercrafts work, and how things hover around on just a cushion of air.
你好，休。你好，迈克，上周你怎么了？我得了流感。我听说我们有一个重要的作业要做？我们要找到两个与当地小学的一组8岁孩子有关的科学实验，并且在周末前完成。听起来很难。我们应该从哪儿找到实验的灵感呢？我设法从图书馆拿到了两本书。做得好！我们先看看这本书上的实验，看看是否有合适的怎么样？当我们处理设备和实验目的时，我可以记笔记。好的，我看看。第一个实验叫“自制气垫船”，听起来真有野心！注意，你只需要20个气球和一张桌子，你不需要任何特殊的引擎之类的东西。用这些做什么？你把气球吹起来，绑在桌子上使它平衡，当然桌子要颠倒一下，这样孩子就能骑上去了。其他孩子就在房间里面推他们。主要目的是展示气垫船是如何工作的，在气垫上是如何来回运动的。
