不定式to，OG-9和885 B-19

看来把它看成非限定性定语从句更好理解，one相当于which的作用。

paladino

如果把逗号去掉，改写成这样是不是也正确呢？

Astronomers at the Palomar Observatory have discovered a distant supernova explosion that they believe to be of a type previously unknown to science。

本题中，逗号后面是作定语从句还是非限定语从句？谁能再举几个逗号后的连接词省略的例子吗（象本题中）。

是不是可以把 one 当成 which 来看，引导非限定性定语从句？如果两者完全等价的话， that 就必须去掉。
除了 one 其他名词在这种情况下是不是也可以充当同样的成分（好象在其他题里看到过，找不到了）

找到例子了，OG 38
38. Scientists have observed large concentrations of
heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

答案是D

感觉 finding 和 og9 中的 one 作用一样，代替which引导非限定性定语从局，指带前面整个句子。

是这样的吗，请nn指点

不是这样，og9中的one 引导同位语从句，是 supernova   explosion  的同位语，与og38不同

那是不是说这里 one 就相当于 that 的功能，所以如果 supernova explosion, one that they bielieve to be a type previously unknown to science，这里面 that就重复了，去掉that更简洁一些。

不过，one引导同位语从句以前没有听说过呢？

还有一种解释就是： one 是explosion 的同位语, that 以后是one 的定语从句, 定语从句用that 引导，这样是可以的。但是省略that会更加简洁流畅。而且，定语从句里面that也确实可以省略的。

哪位NN能帮助确定一下，这题我折腾了好久呢。

longyear

我自己顶一下。

hougang

不是吧，我一直记得语法都是，当that修饰的先行词在分句中做宾语的时候，that可以省略的哦。

longyear

谢谢hougang.

19. Balzac drank more than fifty cups of coffee a day and died of caffeine poisoning; furthermore, caffeine did not seem to bother Samuel Johnson, the great writer and lexicographer, who was reported to have drunk twenty-five cups of tea at one sitting.
(A) furthermore, caffeine did not seem to bother
(B) however, caffeine did not seem to bother
(C) however, caffeine did not seem to have bothered
(D) furthermore, caffeine did not seem to have bothered
(E) in addition, caffeine did not seem to bother
ANSWER: B
为什么C不对？从逻辑上理解to have bothered应该是发生在seem(ed)之前，用不定式的完成形式不是很好吗？
难道是因为bothered所表达的过去的含义已经被did (not) seem已经表达了？
请各路高手指教，不胜感谢！

-------------------------------------------------------------------------------------------------------------

我觉得C选项中did not 和have 表达重复了

其实题干想表达的意思有两种表达方式，一种是B选项的表达方式，用did not seem to bother, 另一种表达方式是do not seem to have bothered, 具体用哪一种，还要根据上下文来确定。
