“哈哈哈!”今天的科学课引来了同学们的笑声,科学老师教的内容是——细胞。

老师要我们观察细胞,可是我有点疑惑,我们的眼睛又看不见细胞,怎么办?这时,科学老师拿出了一台显微镜。我明白了,显微镜可以观察到细胞。接着,老师将一滴培育出来的水滴滴出来,展示在上面。我一看,好复杂啊!这里面有好多虫在蠕动,好恶心啊!它们似乎还在进食,长得毛茸茸的虫是草履虫,长得像时钟一样的虫叫钟形虫,只见草履虫在上面一直摇动,那样子可真活泼,而钟形虫还在一点点进食,它那T字形的尾巴紧紧牵着那根棉线,从而好固定。

As the roll of camera lens, our contest discovered the paramecium that is about to break up only like that! Its action is slow, be in all the time place revolve, still be made much big paramecium " besiege " occasion a disorder, they resemble be in " dodgems " , the paramecium of that dissension is not participated in among them, always struggle seriously desperately, that appearance can resemble earthnut really, very lovely!

We are complete class person boils one piece immediately, feel happy for them really!

随着镜头的转动,我们竞然发现了一只即将分裂的草履虫!它行动缓慢,一直在原地打转,还被许多大草履虫“围攻”场面一片混乱,它们就像在“碰碰车”,那分裂的草履虫不参与其中,总是认真地拼命挣扎,那形状可真像花生,好可爱啊!过一段时间,已经明显的看见它们中间有空隙了,它们依靠一根线,强硬地弄断了它们之间连起来的线,真聪明!我们全班人顿时一片沸腾,真为它们感到开心!
