秤怎么做呢?我百思不得其解,无奈我只好求教科学书。依照书上的介绍,我找来了纸、剪刀、线、木棍、螺帽和螺丝刀。接下来便可以动手了。我首先拿一条线从螺帽中间的洞穿过去,然后绑在木棍上。可是这线真是不听话,绑在木棍上时,总是从上面滑下来。于是,我给它打了个死结,再用透明胶粘住,这下总算驯服了这匹“野马”。秤砣,完成!接着要做提绳。由于太简单,不出一分钟就搞定了。不过,现在要面临最终考验——秤盘。先拿出纸来,用笔在上面画一个圆形,可圆形却像一个神秘的小精 Scale how to do it? I baffled, but I had no choice but to ask for a science book. According to the book, I got papers, scissors, thread, sticks, nuts and screwdrivers. Then you can do it. I first took a line through the hole in the middle of the nut, and then tied it to a wooden stick. But this line is really not obedient, when tied to a wooden stick, always slide down from above. So, I gave it a dead knot, and then use transparent glue to live, which finally tamed this horse “Wild Horse.” Weighing scale, complete! Then to be done rope. Because it’s too easy, it took less than a minute to get it. However, the ultimate test is now facing - the weighing pan. Take out the paper first, use the pen to draw a circle on it, but the circle is like a mysterious little essence
