(C) being tested for chemically induced damage should be compared to
(D) being tested for chemically induced damage are to be compared to
(E) that is to be tested for chemically induced damage are to be comparable with
答案是A，傻傻得问it is important后跟虚拟吗？

a population to be tested for和a population being tested for 有什么区别?

同问

to be tested means an action, but being tested means a continuous process. In this case, using an action to modify the population will be more ideomatic.

刘振明语法书 52页有解释这个题目。

* It is important (adj. essential, imperative,necessary ect.) + that 用虚拟。（不用加 should）

想请问这题的另外一个问题

a population to be tested ，这里to be tested 是作population的修饰成分嘛？如果是的话，OG里面是认为不定式(to do)结构不能作修饰成分的啊

如og11-24

39. For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.

(A) a method to protect

(B) as a method protecting

(C) protecting

(D) as a protection of

(E) to protect

E选项的解释：the infinitive to protect cannot act as an adjective modifying items; the participal form of the verb, protecting,is required

哪位牛牛能帮忙解答~~~
