化工英语教程读后感锦集(28)

在学习《化学》的过程中,我从中遇到了许多有趣的问题,如:水、氧气、二氧化碳等的元素组成表示方法,怎样写化学方程式等;也知道化学元素有100多种,也明白了什么是物理变化、什么是化学变化;在实验课上,小苏打与醋会产生二氧化碳,还会生出许多白沫。
《三国演义》中诸葛亮第4次释放孟获时孟获去秃龙洞求助,秃龙大王借了哑泉、灭泉、黑泉、柔泉四个毒泉消灭蜀军。哑泉水喝了会哑巴,几天后便死了;灭泉水滚烫,如果用这水洗澡,就会骨肉尽脱;黑泉的水看似清澈,溅到身上就会浑身乌黑而死;人喝了柔泉的水就会浑身冰凉而死。天气炎热,人马争先恐后的喝哑泉里的水,结果个个都说不出话来,生命危在旦夕。诸葛亮也没有办法。幸好一位老叟指点喝了万安溪的安乐泉水才转危为安。你知道这是为什么吗?原来是铜盐在作怪。人只要喝了含有铜盐的水就会吐字不清,因为它可以麻痹人的声带,最后因痉挛而死,那为何喝了晚安溪河里的水可以转危为安呢?因为该水中含有较多的碱,碱和铜盐发生化学反应生成cu(oh)2沉淀而不会被人体吸收,因此达到解毒的功效。
化学的奥妙可真多呀!

Do you know Harry Potter? It’s one of my favourite sparetime readings and it’s written by J. K. Rowling. She had the idea about Harry Potter when she was on train, “Harry just walked into my head.” She said later. She started writing the first edition of Harry Potter the next day.
Harry Potter is a magical school student who wears glasses and has no parents, now he is 16 years old. He is very brave and known by everyone because he is the only person who will not die by devil. At school, he has two good friends, they are Rone and Henry.
