今天是星期天,我在语文书上发现了一个有趣的实验—樟脑球和蚂蚁。于是我就按照书上的方法开始做了起来。

I a moment ago found out camphor ball inside chest, there is a small ant on the cement ground outside door of discovery of as it happens grain is being carried in the past home of in spirits. My rapture, go up with the before ant ground with fast camphor ball drew a white line. Small ant goes to the place that draws a line only, it is hesitant first, stop, moved one build to turn back next, I am extremely open-eyed, did it smell really the flavour of camphor ball? Then I am in again his all round drew a circle. How to want to see this small ant do? Be in at this moment, I discover this small ant is recumbent the inner ring brim of the line ambulates, resembling is to seeking an exit, but turned several rounds,did not find an outlet. Be in write a composition at this moment, I am in curiosity drive of ant all round drew a smaller group again. Although its territory is smaller and smaller, but it still continues to seeking exit, but the “ of “ white line of defence that did not break through me to give him set from beginning to end however. Next I drew the circle of size of a coin again simply, at this moment the miracle appeared, that small ant is roused at a draught it seems that sufficient courage, broke through the first line of defence at a draught, escaped successfully, this is “ of ” be unexpected rescued from a desperate situation probably.

我刚才衣柜里面找出樟脑丸,正好发现门外的水泥地上有一只小蚂蚁正兴致勃勃的往家中搬运粮食呢。我一阵狂喜,用樟脑丸迅速的在蚂蚁面前的地上画了一条白线。小蚂蚁一只走到画线的地方,它先是犹豫一下,停下来,然后就调了一个头往回走,我惊讶极了,难道它真的闻到了樟脑丸的味道?于是我又在他的周围画了一个圈。想看看这个小蚂蚁怎么办?就在这时,我发现这个小蚂蚁靠着线的内圈边缘走动,像是在找一个出口,可是转了好几圈都没有找到一个出口。就在这时作文,好奇心驱动我在蚂蚁的周围又画了一个更小的圈。尽管它的活动范围越来越小,但它仍然继续寻找着出口,但却始终都没有冲破我给他设定的“白色防线“。接下来我索性又画了一个硬币大小的圈,这时奇迹出现了,那个小蚂蚁似乎一下子鼓足了勇气,一下子冲破了第一条防线,成功的逃了出去,这个大概就是”绝处逢生“吧。

Feel puzzled in my heart: “ why ant is fear of so to camphor ball? Then I begin ” to search relevant data on the net. Original, the insect such as ant is very sensitive to camphor ball, every smell what its odour can feel special is uncomfortable, meet rapid departure. because of such, people just uses camphor ball to prevent the dress to be bitten by insect eat by moth.

我心里纳闷:“为什么蚂蚁对樟脑球如此惧怕呢?”于是我开始在网上查找相关资料。原来,蚂蚁等昆虫对樟脑球十分敏感,每闻到它的气味就会感到特别的不舒服,便会迅速的离开。正因如此,人们才利用樟脑球来防止衣服被虫子蛀咬。原来科学如此奇妙啊!(文/张予涵)
