指南针英语小作文【一】
通过学习，我知道了，它之所以能指引方向，是因为地球本身就有磁场，而指南针就是一块磁铁，能以“同性相斥，异性相吸”的原理来指明方向。由于地球的磁场是不变的，所以，指南针的某一端会一直指向南方。（先是从理论上搞清楚“指南针为什么能指引方向”实验，就是要以实践活动验证某一理论或推测。）
磁铁的磁性也能转移到金属物品上。大家可以自己尝试做这个实验：用大头针的一端在磁铁上磨，记住，一定要在同一个地方、沿同一个方向磨。反复多次，大头针就会带有磁性，就可以当指南针来使用了。（强调要点。为什么要这样磨才能成功呢？这里如果能交代清楚这一点就更好了。）
可是，当只有一根大头针而没有磁铁时，你怎么办？听说拿大头针在头发上磨一磨也能当指南针，这是真的吗？实践出真知，让我们来试一试。（在没有磁铁的情况下自制指南针。）
首先，把大头针在头发上磨几下（根据摩擦原理），然后把大头针插进一块泡沫里，放在水面上，大头针转了几圈后，便一端指着南面不动了。（简要介绍制作方法。）我把插着大头针的.泡沫转到另一个方向，结果它还是转回了南面。（制作的结果，成功了。——这一段是写实验过程。）
看来这个方法是可行的，可这是为什么呢？我上网去搜索相关资料。原来，摩擦会产生静电，而电会产生磁场，磁场使非本有磁性物变得有磁性，大头针从而就可以变成指南针了。当然，只有金属制品才可以达到这样的效果。（介绍其原理。与文章第二段所介绍的指南针原理相呼应。）
看来科学的世界是无穷尽的，我们只有不断探索，才能学到更多的知识。

??寓言小故事：The Wolf and the LambaWolf, meeting with a Lamb astray from the fold, resolved not to lay violent hands on him, but to find some plea, which should justify to the Lamb himself his right to eat him. He thus addressed him:"Sirrah, last year you grossly insulted me." "Indeed," bleated the Lamb in a mournful tone of voice, "I was not then born." Then said the Wolf, "You feed in my pasture."
"No, good sir," replied the Lamb, "I have not yet tasted grass." Again said the Wolf, "You drink of my well." "No," exclaimed the Lamb, "I never yet drank water, for as yet my mother′s milk is both food and drink to me." On which the Wolf seized him, and ate him up, saying, "Well! I won′t remain supperless, even though you refute every one of my imputations."The tyrant will always find a pretext for his tyranny.
狼和小羊
一只狼瞧见一只迷路失群的小羊，决定暂缓下毒手，想先找一些理由，对小羊证明自己有吃它的权利。它就说：「小鬼!你去年曾经骂过我。」小羊可怜地说：「老实说，我去年还没有出生呢。」狼再说：「你在我的草地上吃过草。」
小羊回答说：「不，好先生，我还未曾尝过草的味道呢。」狼又说：「你喝过我井里的.水。」小羊叫道：「不，我从没有喝过水，因为直到今天为止，我都是吃着母亲的奶汁。」狼一听这话，便抓住它，把它吃下去，便说：「好!即使你驳倒我每一句话，我终究要吃晚餐的!」暴君总有他暴行的借口。
