倒，没想到这第9题有这么多解释，偶一看到选项，就以为是：they believe to be 是个插入语，就像没看到一样，拿刀切了，扔一边，发现其他部分是瘦肉，不错不错，爽口无比。
不过，现在才发现，原来是我没理解没看懂不细心。
, the one they believe to be of a type。。。背下来嘛，有什么难的。（偶最近一直强调背一些比较好的句型、句法，呵呵）
我苦恼于第9题的that 为什么一定要去掉.
supernova explosion, one that they bielieve to be a type previously unknown to science.
这句能说它错么?
我理解: one 是explosion 的同位语, that 以后是one 的定语从句, 定语从句用that 引导怎么就多余了?
9. Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.
(A) that they believe is
(B) that they believe it to be
(C) they believe that it is of
(D) they believe that is
(E) they believe to be of
OG对正确答案E的解释：
Choice E is best. In the context of this sentence, the infinitive to be is more appropriate than the limited present-tense is in referring to an event that occurred long ago but has been discovered only recently.
其中的referring to an event that occurred long ago but has been discovered only recently也就是说不定式在表达一个“很久以前就发生、但只到最近才发现的事情”时比较合适。但我查了两本语法书，好像也没有这样的说法。哪位大牛能为我提供关于这一点的理论依据、范例、或解释？
ETS不是认为不定式有上述含义和用法
只是因为这里用一般现在时的话会使科学家们的研究缺乏严密性,给读者一个感觉是: 这个event是现在才发生的,甚至招来质疑:那以前呢?以前的你们就不相信了吗?或是不知道?
用了to be可以将过去,现在的时间概念模糊化,甚至包含以后,不会让读者转牛角尖
而且少了点绝对化,毕竟这里科学家只是发现一个event,而没有权利决定这个event是或不是(谁知道这中发现以后会不会被推翻,认为是错误的发现呢)
Can anyone tell me if it's ok if I add "that" before answer E, i.e. "that they believe to be of "
thanks
Can anyone tell me if it's ok if I add "that" before answer E, i.e. "that they believe to be of "
thanks
同意brony的看法。有很多用法是习惯用语，或者更prefer的用法，象believe sb to do sth。
不过后面对to be和 is的解释确实让我收获很多。

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）。
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。

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。
did not 跟 have 重複? 怎麼說呢? 好像又有點說的通? 兩種表達方式也很有道理呢!
有沒有人認同或提出furthur explanation 呢?
did not seem to bother ---一個層次, 單純past tense
did not seem to have bothered---兩個層次, past tense 跟 present perfect, 句子複雜性增加, 邏輯上也比較繞! 還有seem 的關係, 先bother 了一陣子, 才去seem , 句意不對
不知大家意見如何?
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（B）
(E) in addition, caffeine did not seem to bother
如果是把have bothered看成是一个延续性的意思哪，“caffeine看起来好像一直以来都没有困扰他”这样的解释是不是应该比b选项的 to bother 要好那？
I don't mean to challenge the authority, but I think choice C is better than choice B.
Here are some of my thoughts on Q.19.
1. "who was reported to have drunk twenty-five cups of tea at one sitting." modifies Samuel Johnson. To parallel with "was reported to have drunk", "did not seem to have bothered" seems better.
2. Samuel Johnson died even before Balzac was born. Thus "did not seem to have bothered" correctly stated that the action of bother happened before the action seem, which is in past tense as drank ... and died... in the first part of the sentence.

my 2 cents:
1. "have drunk twenty-five cups of tea at one sitting" is a whole part. what it emphasizes is Sam's this speical experience (drinking 25 cups of tea at one sitting, sth that is out of a normal person's range), not the time sequence (this action happened before some other actions). just like in the saying "Been there, done that."
2. - "Samuel Johnson died even before Balzac was born." - this was not mentioned at all, thus it is nonrelevant.
- "seem" really doesnt mean anything, so it is not a comparative to other verbs.

第9题是怎么看出来的啊？好几道都是这样莫名
In the context of this sentence, the infinitive to be is more appropriate than the limited present-tense is in referring to an event that occurred long ago but has been discovered only recently.
从哪里看出来的？ 哪位能解答一下
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（B）
(E) in addition, caffeine did not seem to bother
还是没有理解，我觉得在第二个分句中，did no seem与从句中的was reported对应；而to have bothered与have drunk 对应，所以C应该是对的啊？？

caffeine到说话为止都还没有bothered Samuel又有什么逻辑问题呢？

高人请指点!
高人请指点!
感觉one是从句宾语
选项语序
one （that宾语可省去） (they believe to be) of a type...
正常语序应该是
(that宾语可省去) they believe to be one of a type...
这样理解有问题吗？
