735. The English physician Edward Jenner found that if experimental subjects were deliberately infected with cowpox, which caused only a mild illness, they are immune from smallpox.
(A) which caused only a mild illness, they are immune from
(B) causing only a mild illness, they become immune from
(C) which causes only a mild illness, they are immune to
(D) causing only a mild illness, they became immune from
(E) which caused only a mild illness, they would become immune to
这道题其实很直接,用时态和idiom就能判断出来答案是E了,可是OG的解释中有这样一段话我实在就看不懂
B选项OG里面说用causing表示infecting the subjects with cowpox caused a mild illness only in some of the cases.
原句是:The participle causing suggests that infecting the subjects with cowpox caused a mild illness only in some of the cases - but this does not seem to be the intended meaning.
这个解释怎么理解呢?
