34. 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
这个题目杀法有很多种，首先用单复数可以杀a，b，c。万一您不知道dioxins是复数还是专有名词，还有办法，就是看主谓一致。可以看出，a，b，c都把它看成不可数名词，对应他的谓语are，可杀。
再看看d，e选项，由于and后面有一个完整的句子，用句子结构可以杀d，and后面要么跟that North Americans要么不要and。
现在兄弟我的疑问是，在石林语法讲过一个原则，adj加名词由于名词加that。。。
请问然后再遇到这种结构，可以直接使用，把D杀掉吗？ |
