参考答案

正确答案:B
解析:主旨题型通读全文可知本文第一段是本文的主旨:讲的是a scientific fact:Microscopic organisms are paralyzing fish with unknown toxins and then eating away at their flesh.They might be making people sick too.因此整体讲的是Microscopic organisms,B为答案。(第一段讲的是:听上去像一篇科幻小说,但研究人员说这是一个科学事实:一种绰号为“藻类杀手”的微观生物用一种不知名的(生物)毒素麻痹鱼类,然后食用它们的肉。它们也可能会使人类得病。)
