吸烟的危害有哪些英文回答
吸烟的危害有哪些英文回答
有人认为吸烟可以兴奋神经,帮助思考问题,提高工作效率;还有人说:“饭后一枝烟,赛过活神仙.”真是这样吗?有人实验得出的答案恰恰与此相反.烟草燃烧后冒的烟中含有二十多种毒素,对生命危害最大的要算尼古丁了.仅就这一点来说,吸烟有三大害处:
1)可以直接毒杀生命.有人通过动物试验获得了一些惊人的结果,如:再大的马也经不住注射八滴尼古丁,就会很快死亡;活蹦乱跳的狗,用不了一滴尼古丁注射到静脉里去,就可以将它致于死地;另外,使某些动物长期吸烟后,可以发现有血管收缩,甚至硬化的明显趋向.
2)可以破坏人体的营养成分.吸烟可以阻止人体对维生素C的吸收,尼古丁对维生素C,就有得坏血病的可能性.
3)可以诱发多种疾病.由于吸入人体的烟对呼吸道、消化道等器官有恶性刺激作用,因而有人认为它是胃及十二指肠溃疡、呼吸道感染,甚至为口、唇、舌、食道、呼吸道、肺等癌症的诱发因素.
由此看来,吸烟对人体健康来说是百害而无一利.所以要尽量解除或少吸,不吸烟的人最不要最好不要染上这个嗜好.
