答案有问题吧

C. was 错， 主语是 fossiles

i think the key should be D

WHY?

以下是引用szdaphne在2004-12-17 23:11:00的发言：

i think the key should be D


可是D中的the earliest known mammal on..這個on有問題吧..

應該是the mammal of the Greater ....earliest known是加入修飾的..

但是C中,,was也有問題..照理說,,fossils為主語,,謂語應該為複數才對..

D中的have been似乎改正了這點..

總的來說,,C與D都有點不足之處,,不曉得這樣的理解對不對??

請NN賜教

我也选D，我想的是ON ......ISLAND，不知道有没道理，C我是一开始就用主谓不一致排除了
作者: pp_honey    时间: 2005-1-16 16:46

Agree with Choice: D

A中and dated错, make "it" 指代不清，B “,that they found”严重错，"has been" 主谓不一致，C "this"指代不清，E 是run on 句型，只有D没有明显错误。

agree with D

作者: lilyzy    时间: 2005-1-17 18:22

作者: ame26    时间: 2005-2-1 17:57

作者: tai6996    时间: 2005-2-1 19:25
同意答案為d

标题: 天山5-28

I noticed that most CDers go with D, but how to explain "have been dated" ?? Seems "were dated" is better..


By the way, is there an updated summary for Tianshan series?


Sorry for not in CHinese, as it is too difficult for my computer to show CHinese..

作者: mbapastor    时间: 2005-3-23 09:45
yes, I choose D
作者: nautic    时间: 2005-4-24 22:25

i choose D too

作者: kevincao    时间: 2005-5-9 14:53

D不对：

1）have been dated at 34 million years old，用完成时态没依据

2）making this the earliest known mammal of。原句的主体成分，变成了修饰成分，错

我觉得E对，E没有RUN-ON

E的which有问题,而且如果was dated和made并列的话,中间缺少连词.


即使是有连词的话,从逻辑上来说,并列也不合理.

d !

此题同天山3－17，答案为D
作者: sandiegotj    时间: 2005-9-2 00:24

Obviously,D


Speaking of using past perfect tense in the answer D, I got some grammer explanations for you






























The present perfect is used when the time period has not finished:

I have seen three movies this week.
(This week has not finished yet.)


The present perfect is often used when the time is not mentioned:

Gerry has failed his exam again.


The present perfect is often used when the time is recent:

Ikuko has just arrived in Victoria.


The present perfect is often used with for and since.

Greg has lived here for 20 years.
Greg has lived here since 1978.

这道题也是天山3里面的第17题，是不是应该beautywawa excel版本的答案也改下
作者: scorp_w    时间: 2005-10-31 21:45
D  铁一般的事实
作者: mymengming    时间: 2006-7-14 13:51
到底是什么使sloth成为...最早知道的哺乳动物呢？是化石发现的时候还是其年代？显然是其年代。A与D的区别就是两个修饰成分的限定与否的互换。
A中的错误：第２个was和that was并列，句子没谓语，而且平行缺and
E中的句子就更离谱了，唉！
当时去掉C就是因为那个完成时
A，it指代不清，似乎指代fossils，逻辑意思不正确，and前的逗号错
B，they没有指代对象，it问题同A
C，两个was都错，导致句子逻辑意思不正确
D ，is the best，making the sloth ...用sloth明确对象是ETS常用的正确形式，现在完成时表示到目前为止，已经发生
E，sloth which逻辑意义不对。
总结：一般前面是个句子，后面用分词状语从句伴随表结果等经常是正确的选项
