Any medical test will sometimes fail to detect a condition when it is present and indicate that there is one when it is not.

A. a condition when it is present and indicated that there is one
B. when a condition is present and indicate that there is one
C. a condition when it is present and indicate that it is present
D. when a condition is present and indicate its presence
E. the presence of a condition when it is there and indicate its presence


正确答案--C  我选择了B
这道题非常的让我困惑，，，首先OG说A项中的there is one让it没有指代，这怎么说阿？还有题目中detect后面加a condition when或者when a condition有什么影响呢？还说C项比较平行，但我确实看不出来阿，，，，，困惑，非常之困惑，，，，这道题该怎么判断啊？

大牛 我想问一下，那个状语从句中可以那样省略表语吗？

赞！ 不过我认为and indicate 与 fail to detect 并列:
test will   fail to detect a condition when it is present
               and indicate that it is present when it is not

这题很复杂的说考点很多～
a condition when it is present and indicate that there is one when it is not
1 detect 是及物动词 后面必须有宾语的
2 it 指代 condition
3 and 与 detect 并列
4 that 在标准书面语中 比喻从句的that 不能省略
5 做题时注意未划线的部分 when it is not 省略了表语形容词，因为要前面的名词的话就要用that 或one什么的指代了 所以必须是present
由 第五点就看出来是C啦

detect 后面应该叫宾语的，when不能引导宾语从句，所以要有个宾语，排除BD

A one不对，选C
