题目分析:
本题在很多个动词上都考查了外延和内涵这一个重要的考点。咱们现在用选项分析一个一个地检查。
选项分析:
A选项:本选项有三处错误。
第一,没有主句,我们可以发现,在选项中间有一个连词and, 那么在它身前有一个句子,谓语动词为overcome,其身前有一个连词since,在and身后的句子中,falling可以作为伴随状语,谓语动词为prompt, 这会使得两个谓语动词被两个连词所连接,让本选项没有了主句;
第二,划线部分最后出现了a plan that reduced automobile emissions。我们应该将定语从句that reduced automobile emissions改为不定式短语to reduce automobile emissions,这点考查了不定式和从句的区别。用之于本题,由于减少机动车的排放是一个计划的目的,即,reduce automobile emissions这个行为是主观性的,能被控制而发生的,应该用不定式短语。
另外,本题中“促使(prompt)”的主语用了this,它可以单独做一个代词。但在逻辑上,由于发出prompt的应该是复数名词birds,至少应改为these。
B选项:本选项有三处错误:
第一,fall的时态有误,应该用过去时而不是过去进行时。
第二,“计划”身后应该用不定式短语来做定语而不是用定语从句,该错误同(A)。
第三,代词it的指代对象有误同选项(A)。
C选项:首先,本选项中birds had been overcome by pollution和routinely fell from the sky above Los Angeles freeways是并列句的关系。但在逻辑上,这两句显然无法并列,应该让overcome句做鸟的定语。plan身后应该用不定式短语做定语,该错误同(A)。
D选项:Correct. 本选项在语法和逻辑上均是正确的。其中现在分词短语prompting officials in California to devise a plan是伴随状语。
E选项:overcome by pollution是过去分词短语,routinely falling from the sky above Los Angeles freeways是现在分词短语,两者在语法上可以由and连接表示平行。但是,在逻辑上,这两句并没有并列关系,该错误同(C);prompt不应用过去进行时。
我要被这个解释笑死哈哈哈哈哈
The biggest problem in Choice E is that the core of the sentence is "birds ... were prompting". According to that sentence, the birds themselves were "prompting" political action, during the timeframe of the sentence. I.e., while they were falling out of the sky, cold and dead, they whipped out their telephones and called California politicians.
这个必须手动哈哈哈哈哈哈一下

A this只能指代名词不能指代事件
B it错误同A
C had been时态错误
E birds无法prompting
从逻辑语义上讲,我认为prompt的主语不应该是birds吧,应该是birds的这个行为吧?
我也觉得不是birds而是这整个现象
我也赞成
赞同

不认同解析中 promoting 表伴随,应该是做结果状语,因为 bird 不能 promoting,fell 和 promote也不能同时发生
这个d 选项里面promote 动作的发出者可以是这个bird嘛?
A, and falling没有并列对象,错误
B,it指代了一件事情,错误
C,plan that,减少尾气排放是plan的目的,而不是内容,用the plan to do sth
D,ok
E,and falling错误同A
DE比较:
D中overcome做定语,fell是实义动词,prompting是birds跌落的结果
E中overcome和falling都是分词做定语,因为鸟的被overcome而不是征服了pollution,主句缺少动词,错误
C:birds had been overcome by pollution and routinely fell from the sky above Los Angeles freeways,合句中的两句话是具有逻辑关系的,不能用并列体现,E同理。
E的问题还有主语是birds
考点:
1.平行结构
2.代词
3.动词时态
A:and前后句式不平行,this不能指代事件
B:it指代个啥,had been时态错误
C:had been时态错误
E:and前后句式不平行,鸟能prompt个啥
我觉得鸟被污染影响跟从天上掉下来是一个递进关系,肯定是先被污染影响了然后才会从天上掉下来,所以可以排除ACD,另外it的指代模糊不清,所以正确答案就是D
* "Since" + "prompted" = redundant. [AB]
"X prompted Y" means that Y happened because of X. So, if "since" is used to mean "because", you can't also use "prompted".
eg.
Since John was hungry, he ate the hamburger.
Hunger prompted John to eat the hamburger.
不认同解析里针对A提出的第三个错误。
不是this指代单复数的问题,而是找不到指代对象
如果像解析里说的那样,改成these 那就成了birds are prompting ;显然,鸟是不能发出这个动作的
prompt需要修饰整个句子,所以应该用prompting
代词与先行词单复数要一致;语义,and前后两个动作是否平行
注意a plan that reduced表示plan发出reduce这个动作,不合逻辑,应该是officials发出
a plan to do kill ABC
E中were prompting表示鸟类下坠的过程中促进了xxx,发生在一个timeframe里,不可能
D中,prompting 作伴随状语,修饰的是前面整句话的idea
overcome的过去分词还是overcome
C选项:首先,本选项中birds had been overcome by pollution和routinely fell from the sky above Los Angeles freeways是并列句的关系。但在逻辑上,这两句显然无法并列,应该让overcome句做鸟的定语。
在高分库,this其实不是不能当代词,可以当,当时也一定要对应单数形式,否则要用these
it不是可以指代从句么,那B中的it为啥不能指代前面整个since带的原因状语从句呢?
plan 后接to do做定语
