ft，我错了。it没有指代，关键的错误。我马上就要考了还每天晕晕的，
Q20:
In the mid-1970’s, since birds were overcome by pollution, and routinely falling from the
sky above Los Angeles freeways, this prompted officials in California to devise a plan
that reduced automobile emissions.
A. since birds were overcome by pollution, and routinely falling from the sky above
Los Angeles freeways, this prompted officials in California to devise a plan that
reduced
B. since birds that had been overcome by pollution were routinely falling from the
sky above Los Angeles freeways, it prompted officials in California to devise a
plan that would reduce
C. birds had been overcome by pollution and routinely fell from the sky above Los
Angeles freeways, prompting officials in California to devise a plan that reduced
D. birds overcome by pollution routinely fell from the sky above Los Angeles
freeways, prompting officials in California to devise a plan to reduce
E. birds overcome by pollution and routinely falling from the sky above Los Angeles
freeways were prompting officials in California to devise a plan to reduce
答案是D 我選A
我有疑惑的是 選項D ,prompting 這個結構 是 指伴隨的動作嗎?? 可是前面的主詞是birds birds不會prompt 我以為是 前半句 這件事prompt official
A不对，因为前后两个分句之间无连词连接。
D中的现在分词是修饰前面整个句子的结果状语。
A不对，this不能单独做主语
E也不对，不是bird促使， 而是bird老是砸下来促使政府采取措施
這句的主要verb是哪個字啊???
i think it's " fell". 請指導.
this 主语
prompted 谓语
B应该是答案： since birds (that had been overcome by pollution) were routinely falling (from the
sky above Los Angeles freeways), it prompted officials (in California) to devise (a
plan that would reduce...)
A：的this不能作主语。
E：有2个动词，容易产生误会，搞不清哪个是谓语。
哪位NN指教一下。这个D很诡异啊。B不可以么。确实devise a plan to do 更好一些，但是D读起来觉得很不完整
这道题和OG259还是不大一样把。
259. Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
(A) bringing
(B) and brings
(C) and it brings
(D) and it brought（A）
(E) and brought
我也一样，只是比你晚一天而已。
在筛选完剩下C，D后，我最后还是选了C，当时感觉从句修饰plan比较好。请问C为什么不对？是因为不能用过去完成时吗？
o,懂了，为什么C错
C的错误:
1.不简洁,参考D
2.had been...错,虽然动作有先后(be overcome和fell),但是这里并没有强调
我觉得简洁这个东西不能拿来当作排除一个选项的充分条件.
C里面, birds had been overcome by pollution and routinely fell from the sky above Los Angeles freeways, prompting officials in
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
E除了时态不好以外, 没有什么错呀?
choose D, refer to OG 49
我觉得简洁这个东西不能拿来当作排除一个选项的充分条件.
C里面, birds had been overcome by pollution and routinely fell from the sky above Los Angeles freeways, prompting officials in
1.前面有具体的时间状语In the mid-1970’s,.....
這樣是不是代表確切時間點出現時
最好用過去式呢???
2.我還是難以排除C
基本上我覺得C沒有什麼大錯誤....
誰來點一點我阿???

我的理解是这样的，C有2点不好：
1. 使用了过去完成时，从OG中已经体会到，ETS不喜欢过去完成时态，一定要是表示过去的过去才使用，这里完全没有原因要使用它。另外，本句时间状语是In the mid-1970's典型的过去时时态标志。
2. to devise a plan to do sth. 比 to devise a plan that reduced ...要好！ 提出这个计划是为了。。。的目的，而不是针对这个问题在1970年提出一个已经减少汽车排气污染的计划。 注意看c的结尾是 a plan that reduced.
希望对你有帮助！

这两道题我都做对了，对于答案也没有质疑。但是我当时作对完全是靠语感不是很清楚究竟这种两个动词连用是怎么回事，什么时候可以，什么时候不可以，明白的xdjm们给我讲讲吧！这样考试的时候碰到了才可以保证不错！
非常感谢~~
原来是这样啊！嗬嗬。。。谢谢！
to kenshin ,
isn't "Since" a conjunction here ?
I thought the key mistake in A is that "were overcome" is wordy and that "this" has no prenoun can refer to.
is that correct ?
As for B, it's wrong adv tense, "had + pp" is not a correct tense for "in the mid-1970's"
just sharing the thoughts, please advise. thanks
请问E为啥不对
感觉D 和E一样
I think B is the right answer!
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
E除了时态不好以外, 没有什么错呀?
頂一下 我也想知道 選了D 是不是有改變句意了??
B不好吧，过去完成时用的毫无理由，也改变句意，was falling用的更不好，总不能说是鸟正在往下砸，使得政府出台一个计划……
支持D，我想是鸟往下砸的事实逼政府出台的计划，所以合理中心就应该是fell from the sky，而前面的overcome by pollution是修饰鸟的，也表示一个愿意吧
D. birds overcome by pollution routinely fell from the sky above Los Angeles freeways, prompting officials in California to devise a plan to reduce
请問為何要用被動式? that were ?
~如果是that were 的省略, why isnt it --> (that were) overcame
~~先謝謝大家了~~
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
同问
E没有不平行呀，and两边都是分词结构，一个被动，一个主动。
我想问E不对是因为谓语动词were prompting的错误吗？
D中两个to连用可以么？
沉帖好久了，，，但ＭＳ有个问题没有人回答，我也弄不清楚，再翻出来问问。
前面有两位问的，在此题中Ｄ把Ａ选项中的从句变成了主句，是不是改变了意思呢？不是说要尽可能的保持Ａ的意思吗？
期待解答。。。谢谢
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
这题的考点不在此，相比之下，Ving的那个句子代表前面这个事情，整个对后面的影响，所以用的ving，OG上很多类似的，请仔细阅读。这也是ETS的偏好。
A不对，this不能单独做主语，B的it不能指代前面的句子。D中的overcome前省略了了that were，所以位于为fell（定语从句经常用的手法）
A不对，this不能单独做主语，B的it不能指代前面的句子。D中的overcome前省略了了that were，所以位于为fell（定语从句经常用的手法）
那也应该是overcame啊，这里太奇怪了，还是不能理解overcome by pollution做什么成份
那也应该是overcame啊，这里太奇怪了，还是不能理解overcome by pollution做什么成份
原来overcome的原型和一般过去式是一样的,晕
E没有不平行呀，and两边都是分词结构，一个被动，一个主动。
我想问E不对是因为谓语动词were prompting的错误吗？
e 中的and两边是不平行的 falling--〉fell，否则就没有谓语了
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
A this作主语；BC时态不对;E birds作主语了 而这句话的意思中prompt的修饰对象是一个现象 这道题考点也是doing－句子作用题 所以只有选D
但是D 把原来的主句的内容变成了分词结构, 原来的从句变成了主句???这样干可以马?
结构的改变并没有明显改变句意,而且其他选项都有语法错误,GMAT语法是从5个choice中选最好的表达
大家都不覺得這題五個答案都不好嗎
A.this指代不好不能指前面一整句
B.it無指代
C.時態錯,wordy
D跟E.就算分詞prompting可以指前面一整句,時態用現在式也不對,根據longman字典:
overcome past tense overcame past participle overcome
overcome前面沒有have或had就表示是現在式,句子是表示mid-1970要用過去式
所以如果題目沒錯五個選項都有決定性的錯誤
真要選A還比較好
一點淺見...
open to discuss...
"overcome" here is not a present tense, it is past principle, express "passive", "past" and "finished".
呵呵，本来不想说什么的，发现前面争论很多
(A)were overcome和and后面的routinely falling不对称，而且因为falling前有and，所以也不可能falling是修饰前面整个一句话或者修饰birds/pollution；this在句中单独出现，是指代错误，不能指代前面整个句子，无指代对象；
(B)我拿到的选项内容是same as A，so no comments；
(C)had been overcome过去完成时，整个题干没有过去完成时的标志，考虑错；
(D)正确，overcome过去分词修饰birds，routinely fell from谓语，prompting是语法点：对象/事物本身不能说明什么问题，发生了一定的变化才能说明问题，birds本身是不能prompt的，而是前面整个这件事情prompt；
(E)were prompting这个时态过去进行时，一般无明显标志或者时间说明考虑错，另外就是were prompting的主语是birds，逻辑上也不对。
再就是to reduce更强调目的性，而that reduced则表示是一个什么样的plan。
D .birds (overcome by pollution routinely) fell from the sky above
或者
birds overcome by pollution （routinely fell from the sky above
这个routinely是不是有修饰歧义啊。
据此，D没看两眼就给排除了。
摘自longman上面的解释
[usually passive] if smoke or gas overcomes someone, they become extremely sick or unconscious because they breathe it
The engineer was working on the freezer when he was overcome by gas.
这里overcome应该用被动形式，结合所给选项，预测B应该是最终答案
呵呵，本来不想说什么的，发现前面争论很多
(A)were overcome和and后面的routinely falling不对称，而且因为falling前有and，所以也不可能falling是修饰前面整个一句话或者修饰birds/pollution；this在句中单独出现，是指代错误，不能指代前面整个句子，无指代对象；

再就是to reduce更强调目的性，而that reduced则表示是一个什么样的plan。
楼上亲爱的，你错了：）看看前辈的解释，很清晰，呵呵还是应该选D的。
顺便再说一下这题的主要考点：主谓搭配和逻辑意思
看题可知是明显的“事情发生导致政府法律法规的制定”问题，因此应该是谓语prompt用ing形式表政府法律法规，因为XDF的Jacky总结过，政府法律法规具有强制性，要用现在分词表重复性的动作，因此明确题意后马上通过prompting排除ABE；
此外，C的had been overcome也是把原文的过去时改过去完成时，是时态考点的典型错误。
Thus, D
请指教：）
D .birds (overcome by pollution routinely) fell from the sky above
或者
birds overcome by pollution （routinely fell from the sky above
这个routinely是不是有修饰歧义啊。
据此，D没看两眼就给排除了。
B应该是答案： since birds (that had been overcome by pollution) were routinely falling (from the
sky above Los Angeles freeways), it prompted officials (in California) to devise (a
plan that would reduce...)
A：的this不能作主语。
E：有2个动词，容易产生误会，搞不清哪个是谓语。
B的问题很多。
1。 that had been很罗嗦，可以省略
2。 were routinely falling 时态不对。句子是在陈述一种过去的事实，没有原因去用过去进行时
3。在GMAT中it和which一样，不能指代句子。
good
同意D
birds（主语） overcome（分词修饰主语） by pollution routinely fell（谓语） from the sky above
A不对，因为前后两个分句之间无连词连接。
D中的现在分词是修饰前面整个句子的结果状语。
A 的错误是this不能指代前面一句话,而不是没有连词.这句话since是连词.
B,it指代前面整个一句话,错
C,had时态错 1970没有过去的过去,不用过完
E,错的没方向了. overcomed过去分词修饰bird,bird 和falling通过and平行,错光了.(或责理解overcome和falling平行,那么就是bird promote了)
A 的错误是this不能指代前面一句话,而不是没有连词.这句话since是连词.
B,it指代前面整个一句话,错
C,had时态错 1970没有过去的过去,不用过完
E,错的没方向了. overcomed过去分词修饰bird,bird 和falling通过and平行,错光了.(或责理解overcome和falling平行,那么就是bird promote了)
楼上关于E项的评价用词用得太棒了！反正就是错得都没谱了。。。
PROMPTING 现在分词作伴随结果状语。
D的结构更简洁。
复习初中知识：
现在式
vercome
过去式：overcame:表示过去发生的事，一般过去式用
过去分词：overcome:完成时态和被动语态用
D中使用overcome是正确的，表示被动
A不对，this不能单独做主语，B的it不能指代前面的句子。D中的overcome前省略了了that were，所以位于为fell（定语从句经常用的手法）
＂A不对，this不能单独做主语，＂意思是this必须加名词？？？
但不是有＂to be or not to be，that is a question＂这句话么？
这问题困扰我一直
而且不是经常有说＂这是一个问题＂这之类的话？

A. since birds were overcome by pollution, and routinely falling from the sky above

B. since birds that had been overcome by pollution were routinely falling from the

D. birds overcome by pollution routinely fell from the sky above Los Angeles
freeways, prompting officials in California to devise a plan to reduce
E. birds overcome by pollution and routinely falling from the sky above Los Angeles
freeways were prompting officials in California to devise a plan to reduce
C 的错误还在，伴随状语 prompting 可以修饰birds fell from the sky，也可以理解为修饰 birds had been overcome by pollution and fell from fell 两件事情共同导致的结果
C 的错误是否还应该算上and 前后不平行这一条? and 前面是被动, 后面是主动, 如果说and 后的had been 省略了话, 那么鸟被掉下来也不合逻辑啊.
