Question

Very few people understood his speech, __________ was very complicated

Very few people understood his speech, __________ was very complicated.
A) of which the subject B) the subject of which C) the subject of it D) which subject
在AD,犹豫选了a，结果俩都错 - -，麻烦解释下

Answer 1

正确答案是 B。
the subject of which 中的 which 指代 his speech。答案 A“感觉”正确是因为 the subject was very complicated 无疑是正确的。但 of which 是个所有格，of 前面的 the subject 却放到了which 后面，脱离了它们之间修饰和被修饰的关系。所以不对。D 不正确是因为在 which 的位置上应该是个所有格形容词，而 which 却不是。换成 whose 就没有问题了。
B 正确是因为这是一个“非限定性定语从句”，修饰 his speech。
