Festival of annual science and technology arrived again, we wish to join each project. What we had better surprise this year is the gizmo of section of science and technology. Speak of gizmo, classmates comment in succession rise, we are thinking: What thing should invent after all? Because the teacher says what can use in the life to this invention is us certainly, it is for our life more convenient. This comes, can beat I.
一年一度的科技节又到了，我们恨不得把每一个项目都参加一次。今年我们最好奇的就是科技节的小发明。说起小发明，同学们纷纷议论起来，我们都在想：到底要发明什么东西呢？因为老师说这个发明一定是我们生活中可以用的，是为了我们的生活更加方便的。这一来，可难倒我了。
In on the weekend, mom did not know to seek a piece of paper from where, see the thing that oneself can invent is on that piece of paper only, have among them climb stair car, have abstain badminton, have contain toilet soap paper, have abstain flashlight to wait a moment. I look, with respect to make choice of abstain flashlight.
周末里，妈妈不知道从哪里找来了一张纸，只见那张纸上都是自己可以发明的东西，其中有爬楼梯车，有自制羽毛球，有自制香皂纸，有自制手电筒等等。我一看，就选定了自制手电筒。
Target make choice of, we begin to begin to prepare those data, the data that we need has: Of a sky pull coal tub easily, a few thick corrugated paper, two 1 date batteries, a small bulb, a paragraph of electric line, chipboard coils, the composition is double-faced glue, scissors.
目标选定了，我们就开始着手准备那些材料了，我们需要的材料有：一只空的易拉罐，一些厚的瓦楞纸，两节1号电池，一个小灯泡，一段导电线，纸板卷，作文双面胶，剪刀等。
Began to do, will pull coal tub easily to rise first the cap of the head, hammer of another head that use a circle is knocked sunken. Furl with thick corrugated fibreboard then two 1 date batteries, on the positive electrode face of batteries, remove theatrical makeup and costume of negative pole face is entered in pulling coal tub easily. Look for an appropriate plastic cap to buckle in pull coal tub easily, in the small hole that a circle digs in the center of the box, it is advisable that the size of the hole just suits a small bulb, insert bulb base small hole. Take a paragraph of electric line skin of line of two upright expurgation, one aspect of the matter is circled on lamp holder, another end from the blast on plastic lid small see clearly piece. plastic lid the lid is in pull coal tub easily, check, see bulb, batteries whether be contacted cheek by jowl. Arrived here, one-time flashlight has been done.
开始做了，先将易拉罐起掉一头的盖子，另一头用圆头榔头敲凹。接着用厚瓦楞纸板卷起两节1号电池，电池的正极朝上，负极朝下装入易拉罐中。找一个合适的塑料盖子扣在易拉罐上，在盒子中央挖一个圆形的小洞，洞的大小刚好适合一个小灯泡为宜，将灯泡底座插入小洞。取一段导电线两端削去线皮，一端绕在灯座上，另一端从塑料盖上炸一个小洞穿出。将塑料盖盖在易拉罐上，检查一下，看灯泡、电池是否紧密接触。到了这里，一次性手电筒就做好了。
When using, with thumb wear the lead that give to press from sidewall going up from the welding line that draws coal tub easily not to have paint, flashlight can give off light, thumb leaves electric line start, flashlight destroyed, use rise very convenient.
使用时，用大拇指把从侧壁穿出的导线按在从易拉罐无油漆的焊缝上，手电筒就会发光，大拇指离开导电线跳起，手电筒就灭了，使用起来非常方便。(文/赵惠娴)
