E. sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of
问题：B项中，OG上说they无指代，在逻辑上应该是指代前面的fossils，但是这里为什么不能指代fossils呢，found作形容词修饰they不可以吗？

naoyixue

题外话， “，that..."错误， that最好是紧跟修饰的名词，限制性定于从句（但是很少也可以“N,that..."很少，我看见过。

只看见过 noun + doing/ done后置修饰前面的名词，但是没有noun + 代词+ doing/done.这个错误

naoyixue

而且，Fossils of the arm of a sloth ， found in Puerto Rico in 1991 也不好，可能修饰sloth,也可能修饰fossils.

frankiyian

ABC指代错误，IT距离这个sloth太远，且有歧义（是使fossil of arm变成最古老的mammal？）C的话更明显，this不能单独用作代词。
DE我是看后面的连词确定的，[on] the islands.其他的问题也不太确定，同求指教

支持，that不能用于非限定性定语从句。

谢啦，战友们都很热心

B项中的they为什么不能指代fossils呢？我很好奇，还有就是这个我是知道的，但是很少用这个作为判定标准，再看曼哈顿的时候那上面明确写出一般情况下最好不要用that前无逗号，which前有逗号作为判定标准，整个og12og13里也没有以此为考点，只是说有根据句意此处可能更适合限定性定语从句或者更适合非限定性定语从句

gui59106375

我觉得说it无法指代是因为离得太远，因为fossils是复数，it不可能指代它，还有就是B项为什么they无法指代fossils呢

gui59106375

这个说的没错，但是noun+V-ed/V-ing什么时候可以这样用呢，能否解析一下用法

naoyixue

Fossils of the arm of a sloth found in Puerto Rico in 1991, 这个其实就是例子， found in P R 后置定语，类似于something wrong 这个结果，noun + 修饰的结构。 只是Fossils of the arm of a sloth found in Puerto Rico in 1991这个句子不好，其实found修士fossils,但是这里面紧跟在sloth后面，变成在1991年找到的sloth，改变原文的意思，其实也不逻辑

naoyixue

我觉得你应该先整体的巴语法看一下，再搞小的细节。
