OG63

Health officials estimate that 35 million Africans are in danger of contracting trypanosomiasis, or “African sleeping sickness,” a parasitic disease spread by the bites of tsetse flies.

(A) are in danger of contracting

(B) are in danger to contract

(C) have a danger of contracting

(D) are endangered by contraction（A）

(E) have a danger that they will contract

这道题og的解释中说the passive construction in D would be unnecessarily wordy and also imprecise, because it is the disease more than the acting of contracting it that poses the danger 这句话完全不明白为什么。 还有in E, the that clause following the phrase is , within the structure of the sentence, ungrammatical and awkward?也不明白 请指教

in E, the that clause following the phrase is , within the structure of the sentence, ungrammatical and awkward

这句话是什么意思啊？

跟在那个danger后面的that从句是不合文法和笨拙的

如果是定语从句的话，that应该是后面句子的助于或者宾语，而这里后面是一个完整的句子。

难道是that引导同位语从句？不清楚

that引导的是定语从句啊！修饰danger

难道先行词一定要在定语从句中作成分？可以不作吧？

in E, the that clause following the phrase is , within the structure of the sentence, ungrammatical and awkward?

同问, 不是很理解为什么啊? 同位语从句不好吗?

自己顶!

大家帮忙啊, 谢谢了!

try to explain 一下，我觉得是这样的，如果是E的话那么就是：Health officials estimate that 35 million Africans have a danger that they will contract trypanosomiasis, or “African sleeping sickness,” a parasitic disease spread by the bites of tsetse flies.

我觉得E中的they有指代不清的嫌疑，它可以指代officials或Africans，这样就容易造成歧义

略表拙见，欢迎指正，呵呵
