7 q8 d0 b8 F5 V+ c, ]8 o% V第一段的关键词的确是ineffective，说相关实验也少。而在听力里面反驳的时候说的是那个phytoplankton我记得貌似是个什么浮游植物，这个东西can live 2到3个月。而大多数实验只观察了一个月，所以老师认为如果多观察，等到一个月后就会很明显的效果了。- O, z: i! A6 Q0 [" @) [. w# u5 M$ e
第二个关键词就是说toxin这个问题。阅读说害鱼还会hurt吃鱼的人（原文hurt）。而听力说的是你只要不fertilize with iron就OK了，至少我听见是这样子的，等你把这些东西种好了不需要了就不要用铁了就没毒了。 N" f7 z. \+ U0 U
第三段是说破坏生态平衡，阅读说的是你不知道你用这个东西会给ocean的生物带来什么，他们会相互影响最后影响整个海洋的生态平衡。而听力说if you don't take this risk就会有great risk，也就是全球变暖气候变化，听力说这个影响更大，而且也会给整个海洋生态系统带来更大的威胁和破坏。
