Q28:

Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles islands.

sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of

sloth, that they found in Puerto Rico in 1991, has been dated at 34 million years old, thus making it the earliest mammal known on

sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of

sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

答案是C，我选D。

C中明显主（fossils)谓(was)不一致呀。请指教。

作者: tianwan 时间: 2004-6-16 21:52

I agree with you on choosing D. Besides the mismatch you metioned, the "this" in C looks ugly and awkward,

But "mammal of" in C seems better than "mammels on", preposition always confuses me.

NN, pls come to help!

up D.

dated一定是搭配Fossils而非sloth。

作者: 蓝羽 时间: 2004-9-17 06:59
支持D！

作者: bloodcherry 时间: 2004-9-21 22:07
totally agree with D

作者: card_mistress 时间: 2004-9-21 23:22

I think the 'was' modifies 'a sloth,' not 'fossiles', a sloth that was... but even if the 'was' part is right, C is still incorrect because it states that the sloth was found in 1991, but its fossile was dated some million years ago.

作者: Penggary 时间: 2004-10-10 15:14

Q28:

Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles islands.

sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of

sloth, that they found in Puerto Rico in 1991, has been dated at 34 million years old, thus making it the earliest mammal known on

sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on

sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of

答案是C，我选D。

C中明显主（fossils)谓(was)不一致呀。请指教。

I agree D, too, but to make my understanding right and clear, I would like to present my reasoning as following, hoping to get comment from xDJM.\

For A, " found ..." acts as an attributive and directly modifies the closest word, "sloth", so no matter whatever information follows, the sentence is logically flaw because it implies that the sloth found in 1991 have been became fossils. incredible!

but D, "found ..." acts as an adverbial, modifies fossils, the subject of main sentence.

In C, the that clause "sloth that..." produce the same logic flaw as the "found ..." in A.

E is not so clear and concise.

D is the best.

作者: Beijiajia 时间: 2004-11-24 16:53
哈，幸亏得知GWD的keys不准确，要不然我以为自己都不用去考试了。。

作者: vincentcpu 时间: 2004-11-24 20:07

答案應該是 A (雖然一路看來都是 D)

Fossils of the arm of a sloth which was found in PR in 1991, and was date at 34 M years old, made it (sloth) the ealiest known mammal of the GA island.

這題的 D 實在是想不透

1. have been dated at 34 million years 要解釋成 (1) 截至目前被鑑定為 35 M 年... <-- 所以以後可能還會被鑑定成更久的年份ㄇ? 被鑑定的事情本來就發生在過去應該是過去式何來的完成式的道理

2. fossils made the sloth the earliest known mammal of .... 才是這個句子的主要意思，怎會把最主要要表達的動詞 make 用成 making 這種 "降格" 的分詞來表達勒，D 的主要意思都在於 have been dated at ..... 不合邏輯

我还是按时态排除的C，因为肯定是先发现后断代啊。怎么可能都用过去时态？？

A有两个问题：一是found紧跟在sloth后面，有修饰sloth的歧义；二是it指代不明，D中重复sloth是正确的标志。

但是D也改变了句子重心，在逻辑意思上看好像A更符合句子的本来逻辑意思。请大家继续讨论。

I think d is best

A is apparently awkward and illogical, for it is the fossils dated at 34 million years old led the sloth the earlest known mammal not the fossils found in 1991 itself made the sloth earliest konwn mammal

请问，A的错误到底在哪里？

除了楼上讲的外，最严重的是逻辑错误，fossil 本身怎么可能made it the earliest known mammal of....呢，当然是因为fossil be dated 34 million years old 才是真正原因，所以D很清楚的表达了这个意思

作者: Willy57 时间: 2005-6-5 11:11
台灣學生一開始多半會刪掉A不選，因為我們這有一個解題技巧大陸朋友可以參考看看，

and的用法，如果是用在平衡不是說把兩個句子連起來那種，如 It rained yesterday ,and I stayed at home

以這題A選項來說，很明顯可以用平衡來思考，found與dated平衡，

在平衡議題上（不管用and或or或but之類的），平衡兩個前面是不會有逗點的，

平衡三個以上才會有！所以這題一看到是用在平衡兩個以及and前面有逗點，

我們馬上不選！

一般在解題時，只要看到and前面有逗點，台灣學生第一先看這題是不是平衡，

如果是，下一步去找出三個平衡（目前還沒做過平衡三個以上的題目，就算有也一樣的原則）！

比如GWD13回第12題就是個例子，and前面有逗點，看是不是考平衡，是的話找出三個平衡....

大陸朋友參考囉！！至少OG、考古（台灣有一種題目叫考古，ETS舊題目約兩三百題）、以及GWD大致這解題技巧都通！

作者: Willy57 时间: 2005-6-5 11:34
至於用完成式，個人認為本句有兩動詞，發生時間有先後，先發生用完成式，後發生用現在式。

句中先被查驗年齡，後才確認是最早，因此前面用現在完成，後面用現在式。

此外從過去年齡被確定到現在大家都還是認為是那個年齡，所以用完成式也無不妥，

並沒有說過去確認是那個年齡但是現在卻不是了，台灣修辭師祖莫清威就說過我們翻譯得不好，

過去式、現在式、或現在完成式這名詞常會誤導學生......（我不知道大陸是不是這樣翻）

後面那句的架構我們也是A、E直接刪掉，用made表示被動的省略，making表現在的省略，

當然順道一提的，如果用which make或which are made，我們這也是會直接刪除的，

因為which或that是不能代表整個句子的，這句很明顯是前面那件「事情」造成後面那個事情，

如果有which或that，老師會要我們先想他前面有沒有緊跟名詞，

除了有些句子因為由輕到重、好戲在後頭的原則外（這可以解所有大家吵半天的題目，因為這兩原則是最重要修辭技巧，但對我們中國人來說很難體會，老師說你能體會了自然就七百了，不能體會700就看運氣吧），其實這可以套到大部分有which或that的題目！大家參考囉！

作者: handsup 时间: 2005-7-26 17:24
我也认为是d

作者: xulijun 时间: 2005-7-31 13:37

强烈支持D,理由有四：A、该句主要结构:fossiles made it sth..it无指代。B、they found in...,they无指代，如果指代fossils,应该为they were founded in....C、making this sth.,this 不能单独使用指代某物.E、该句主要结构：fossils of the arm of the sloth which made the sloth sth.,句子结构不完整，没有谓语动词。

明白了吧！

作者: lindazhou 时间: 2005-8-28 18:33
have been dated, dated没有明显的使动者，可以用被动式吗，是不是主动更好一些呢。

作者: ericlai27 时间: 2005-10-3 23:08

应该是D，C的was说明that指代sloth了，sloth1991年被发现，逻辑就错了

作者: julietayue 时间: 2005-10-7 05:39

嗯,是选D

因为OG里有个rule是:

前面所有格形式的名词,后面不能用代词指代.

这句中是arm of the sloth,所以后面的it被认为no referent

如果前面有the sloth单独出现,后面可以用it指代.

作者: 饼干人 时间: 2005-10-17 11:33
C最明显的错误是后面用了was去修饰fossilS。C中sloth后的that was found 歧义，可以理解为fossils或者sloth。虽然D好像也有点这个问题，但是用逗号隔开好像比较好。并且C中的this有问题，在GMAT中好像单独出现不太好，后面要有指代的对象，比如this book。D中making应该是现在分词作状语表结果

作者: ffanghua 时间: 2005-11-21 21:02

D让我想不通的只有一点，就是说date应该是一个瞬间动词，就是“鉴定。。的年份”的意思，应该是瞬间完成的，没有用完成时的理由，而且句子中也没有明显的时间状语。

作者: zhchch 时间: 2005-12-4 22:29

C、D比较：

（1）found优于that was found，后者没有前者简洁。

（2）对于一个过去发生的事件，题中没有任何提示需要用现在完成时，was dated优于have been dated。

作者: zhchch 时间: 2005-12-4 22:31

用石林的标准，这两处都是硬伤，C、D各有一处。

所以我很迷惑，希望得到NN指点：）

作者: 乌龙茶 时间: 2005-12-29 13:08

作者: barry996 时间: 2006-1-19 13:37

光从MAKING THIS这个上面就应该可以排除C, THIS可以指代的东西太多了, 明显的歧意

D虽说有点怪, 不过把原文的IT换成一个很清楚的名词, 这个名次再逻辑上也是成立的, 这就是ETS正确答案很明显的感觉

一点陋见, OPEN TO DISCUSS....

作者: AnimalPlanet 时间: 2006-3-9 06:37

D不是有点怪，而是特别怪......

但是相比于C的莫名其妙的错误，D还是应该比较能够接受的.

真正考试会遇到类似的混浊不清的题目吗？

作者: dudegmat2006 时间: 2006-7-11 20:27

A-incorrect use of past tense "made" when, apparently, the sloth continues to be the earliest known mammal of the Greater Antilles; a condition which requires the progressive tense "making" to accurately relate the ongoing nature of the condition;

B-"they" has no clear referent, plus, the construction is awkward in the terminal clause;

C-subject-verb agreement error--"Fossils" is plural, "was" is singular;

E-combines the problems of A and C.

前面某位提到的og211:
211. The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic people has been established by carbon-14 dating, but what is much more difficult to determine are the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals.
(A) has been established by carbon-14 dating, but what is much more difficult to determine are
(B) has been established by carbon-14 dating, but what is much more difficult to determine is
(C) have been established by carbon-14 dating, but what is much more difficult to determine is
(D) have been established by carbon-14 dating, but what is much more difficult to determine are
(E) are established by carbon-14 dating, but that which is much more difficult to determine is
Two instances of subject-verb agreement must be observed in this sentence: The period... has been established and what is much more difficult to determine... is. Both clauses have singular subjects and must have singular verbs. Only B, the best choice, observes these requirements. A incorrectly uses the plural form are in the second clause. Choices C and D incorrectly use the plural form have in the first clause, and D incorrectly uses are in the second clause as well. E incorrectly uses the plural form are in the first clause. Furthermore, because the date of the period in question was established before the writing of the sentence, the verb of that clause must be in the present perfect form (has been established).

A的[逗号+and]是个错误，正如前面某位台湾兄弟所言，两个动作的平行结构，and之前是不要逗号的。
遇到[逗号+and]，就赶紧看看它是不是三个或者三个以上以上平行并列成分的最后一个，如果不是；再看它是不是连接两个句子；如果都不是，就差不多该排除了。

C的问题除了楼上所标出的黄色警示之外，making this the ...中的this在此处是个光杆司令，记得XDF的老师说，这种情况下this,that等代词裸奔一般为错。

在这里and dated at 34 million years old　很明显符合　大段时间概念　　因此Ａ不对

作者: yinlixiao 时间: 2008-9-19 12:08
这里一系列动作的主语是fossils, 是fossils 被发现，被确定年代，不是a sloth. 所以那些定语从句都有修饰a sloth的嫌疑， D用逗号跟主句隔开，分词优先修饰主语fossils.

D为什么用现在完成式啊？E错在哪？请指教～

现在完成时可以表示过去动作延续到现在，显然，那个化石有 3400 万年是一个延续的动作，如果改成过去时，表示过去是 3400 万年，现在不是了，逻辑不通。

E 首先是 fossils 和 was 主谓不一致，即便是在 which 从句里头。而且定语从句 which 修饰 fossils 离得太远，也容易引起歧义。至于在 which 从句里面在插入一个分词短语，结构更加令人难以接受。最后那个 made 也不好。因为使得sloth成为最早的哺乳动物不是fossils ，而是fossil 已经 3400 万年这个事。

作者: Jasonhere 时间: 2010-3-6 23:00
总结一下：（仅供参考）主要是在AD中选择
1. what was/that is是啰嗦的选项
2. 主语是fossils，注意主谓要一致
3.AC的found前无逗号就近修饰sloth；D的found前有逗号，修饰the subject of main sentence
4. B选项刨除插入语后，has不能与fossils主谓一致
5. A中it指代不明
6. A中made it的主语是fossils，不合逻辑意思，fossil 本身怎么可能made it the earliest known mammal of....呢，当然是因为fossil be dated 34 million years old 才是真正原因
7. A选项中两个对象并列直接用and即可，不需在and前加逗号

作者: wcc0523 时间: 2010-4-3 14:47

I agree with you on choosing D. Besides the mismatch you metioned, the "this" in C looks ugly and awkward,
But "mammal of" in C seems better than "mammels on", preposition always confuses me.

我记得OG12上有逗号加and表两动作并列的，只要同属主语没歧义，就可省略，不是什么必错规律·

作者: undefeatedxk 时间: 2012-4-14 12:50
根据OG12的解释
个人感觉可以这样理解A：1.逻辑意思错误
2.it要是指代的话只能指代一个整体，在这里就是主语，而主语的核心词是fossils所以it本身就没有指代，而不是指代不清
