This morning, I am playing a mobile phone with pleasure, suddenly a small video attracted me, what content tells is the scientific test that lays cable about attrition. I think: Have really so magical? I do not believe, ear listens for empty, the eye sees for solid. I decide to do an experimental test and verify with one's own hands.
今天早上，我正在津津有味地玩手机，突然一个小视频吸引了我，内容讲的是关于摩擦生电的科学实验。我想：真的有这么神奇吗？我不相信，耳听为虚，眼见为实。我决定亲手做个实验验证一下。
I take out experimental data above all: Two pens, cup of a paper, a piece of paper. Insert a pen into the bottom of paper cup next, the appearance of umbrella of white paper make it, put in the coping of the pen, after I used another pen to chafe a few times back and forth on the head, put in " spit umbrella " at the same time, see it whether can follow a roll, but its anyway does not agree to be moved, it is as stable as a mountain really. Search want: Because my attrition time is too short,be, bring about so " small composition umbrella " move do not rise? Then, I go up in the head with the pen again, on the dress, on the leg... chafed everywhere. Next I am put cautiously in with the pen again " spit umbrella " at the same time. Eventually miraculous happening, my pen resembles a commander, as long as " commander " turn where, "Spit umbrella " also turn where accordingly. I skip 3 rule are high, cry happily rise: "Emperor day does not lose an observant and conscientious person, the experiment succeeded eventually! The experiment succeeded eventually!!
我首先拿出实验材料：两支笔，一个纸杯，一张纸。然后把一支笔插进纸杯的底部，白纸做成雨伞的形状，放在笔的顶部，我用另一支笔在头上来回摩擦了几下后放在“小雨伞”的一边，看它是否能跟着笔转动，但它死活都不肯动一下，真是稳如泰山。找想：是不是因为我摩擦时间太短，所以导致“小雨伞”动不起来？接着，我又用笔在头上、衣服上、腿上……到处摩擦了一遍。然后我再次用笔小心翼翼地放在“小雨伞”的一边。终于奇迹发生了，我的笔像一位指挥官，只要“指挥官”转到哪里，“小雨伞”也跟着转到哪里。我一蹦三尺高，开心地大叫起来：“皇天不负有心人，实验终于成功了！”
At this moment, mom came back. I run over, ask at once: "Mom, why to meet such? " mom is laughing to say: Because the meeting after pen attrition hair is electrostatic,be, and electrostatic have adsorptive capacity, can suck the little thing such as the scrip, this is the principle of attrition unripe report. This is the principle of attrition unripe report..
这时，妈妈回来了。我跑过去，连忙问道：“妈妈，为什么会这样呢？”妈妈笑着说：是因为笔摩擦头发后会静电，而静电有吸附能力，可以吸纸片等微小事物，这就是摩擦生电的原理。”
Heard mom's word, I understood to want serious study to be good at thinking only, can acquire more and interesting scientific knowledge.
听了妈妈的话，我明白了只要认真学习善于思考，就会学到更多有趣的科学知识。
