标题: GWD17-Q38 没人问,求助 9.4
GWD17-Q38:
All Y chromosomes in existence today are
descended from a single ancestor’s who is thought to have lived about
140,000 years ago.
- a single ancestor’s who is thought to have lived
- a single ancestor’s who was thought to live
- a single ancestor whom it is thought had lived
- the Y chromosome of a single ancestor who is thought to have
lived - the Y chromosome of a single ancestor whom it was thought had
lived
答案D 我错的比较冤 我选的是A 我想问下,细胞染色体最开始是一个还是一群??
我就是为了选一群选的 A
怎么从文章里面体现的呢???

A错,who不能修饰所有铬
作者: waiu_0235 时间: 2006-9-7 16:21
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

请问 have lived 怎么后面的时间状语是 140,000years ago?
作者: irislei 时间: 2009-6-19 09:39
我也想问问这道题时态的问题140,000years ago为什么用完成时?

对于现在完成时的解释,在这句话里从两个角度去讲可能会比较清楚
1.现在完成时表示"过去发生的事情对现在造成的影响",原句的意思就是说,染色体从祖先那里传下来这件事情对现在是有影响的,所以用现完
2.原句的时态用的是现在时,主句里面谓语动词是are,所以从句里的时态应该与主句一致,也用现在时态
不知道说得对不对,望大虾们指正~

我怎么觉着about 14000 years ago是一个过去的时间点,祖先是在这个过去时间点之前就存在了,如果这样我认为应该使用过去完成时啊!
欢迎nn拍砖~~
作者: abbyabby 时间: 2009-8-19 16:51
嗯 是这样的 be thought to have done~~~表示过去时,相当于did
