我是用be 動詞的平衡來解題
(A) All Y chromosomes 不等於 a single ancestor’s
(B) (C) 同上
只剩下D E
(E) whom it was thought had lived
不如(D) consice, 至於whom...我只是覺得很奇怪而已,不過我不會解釋
for example: He is thought that he is a great teacher
-------------> He is thought to have been a great teacher
who怎么能修饰ancestor 的染色体呢?
应该修饰ancestor才对阿 :)
D. the Y chromosome of a single ancestor who is thought to have lived
问一下D 中who 能改成whom 吗?
肯定不能改成whom, whom应该在从句中做宾语,但是定语从句中缺少的成分是主语,必须用who
