OG11-69 关于dioxin是否可数的问题

69. A report by the American
            Academy for the Advancement of Science has concluded that much of the currently
            uncontrolled dioxins to which North Americans are
            exposed comes from the incineration of wastes.

(A) much of the currently uncontrolled dioxins to which North Americans are exposed comes

(B) much of the currently uncontrolled dioxins that North Americans are exposed to come

(C) much of the dioxins that are currently uncontrolled and that North Americans are exposed to comes

(D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come

(E) many of the currently uncontrolled dioxins to which North Americans are exposed come

我查了朗文字典，dioxin的解释是不可数名词，没有可数的解释，可是为什么这道题是可数名词，怎么解释？

我的理解是

这题明确给出了 dioxins ，所以考点不是 dioxin是不是可数名词，而是 dioxins究竟是专有名词，还是复数形式的问题，就像那个cirtus一样。

至于dioxin，可能用来泛指二噁英的时候是不可数，而确指时应该是可数的，毕竟二噁英有很多很多种。。

1楼同学说的对，我今天也被65的柑橘树和69的二噁英纠结得掰不清：如果是用dioxins来表明多种类的二噁英，为什么后面不用“many kind of”？如果不用kind，应该还是指的二噁英的“量”，这样的话就得用“much”才说得过去吧...头痛~

因为 dioxin 已经加了S 暗示这里表示的dioxin的种类；如果是从总体意义上说dioxin这种东西应该是不可数的就像 money water 一样~~ 不知道理解的对不对

新牛津上说dioxin是count noun,在表示不同种类的化合物时，而且和一楼说的一样，这里已经加了S了，就赢子啊表示是一个可数名词

* "much of the dioxins" is not good.
if you're going to use uncountable quantity words, like "much", then you should use them with singular mass nouns (money, furniture, water, etc.)
RON是这么说的
