今天下午，我做了一个试验，我准备了一些材料－－竹子、电池、电线、泡沫。我开始做试验了。我先把电线剥开，里面有两条电线。我又将竹子劈成四条，我将两条电线绑在其中一条竹子上。然后，我把电池摁在电线上。经过一个下午的试验。 This afternoon, I made an experiment. I prepared some materials - bamboo, battery, electric wire and foam. I began to experiment. I'll strip the wire first. There are two wires in it. I split the bamboo into four, and I tied two wires to one of them. Then I pressed the battery on the wire. After an afternoon's experiment. 试验成功了，我万分激动！ I was very excited that the experiment was successful! |
