Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might, but climatologists have indicated all along that precipitation, storminess, and temperature extremes are likely to have the greatest impact on people.
Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,
Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
The discussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,
The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,
题目分析:
focus这个词本身既可以是名词又可以是动词,但是,在(A)(B)两个选项中的focus必然为名词。因为,只有名词身前才能有冠词(a focus),并且也只有名词才能有物主代词(its focus)。划线部分的意思是:对温室效应的讨论一般会关注全球气候变暖的可能性,以及会达到何种程度。
选项分析:
A选项:主谓不一致,主语discussion是单数,所以其谓语动词也应为单数,即,has;
其次,本选项可以看作一个倒装句,还原为正常语序则有:
Discussion of greenhouse effects have usually had the possibility as a focus.
按照字面理解,这句话的意思是,讨论拥有一个可能性来作为关注。显然地,这是不正确的。正确的意思是,讨论关注了一种可能性。
再次,possibility定语部分(of型所有格)的核心词为Earth(Earth身后的现在分词短语growing warmer是它的定语),但在逻辑上,我们关注的应该是地球变暖这个事件的可能性,而不是地球本身的可能性。
B选项:focus错误同选项(A)。
C选项:Correct. 本选项在语法和逻辑上均是正确的。很多同学可能不明白这里由并列连词and连接的两者平行的现象。实际上,这是一个省略和倒装的现象,还原后则有:
Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and Discussion of greenhouse effects has usually focused on what extent Earth would grow to.
划线部分均为省略内容。介词to倒装在了what extent身前。
D选项:主谓不一致错误同(A);核心词错误同(A)。
E选项:and连接的两者不平行,即,the extent that is和whether Earth would grow warmer不平行。前者应该改为:to what extent。
选项应该省略了一些东西吧, whether Earth would grow warmer and to what extent ( would grow warmer) ,所以说这样的话前后两个就是可以平行的结构了
D and连接的两边不平行啊,focus on the possibility 没有错吧

省略+倒装 mark
whether和to在功能上是平行的吗?
不理解C最后的and,到底指的是什么和什么的平行?E怎么就不平行了?
选项里的解释很清楚呀,指的就是两个句子的平行。E里少了介词to,就只能是名词的平行了。

B选项能否看成1个倒装结构呢?还原正常语序以后是:
Discussion of greenhouse effects has usually had
whether Earth would get warmer and what the extent would be
as its focus?

关于倒装和省略的情况能在本周四答疑课上详解下吗?什么样的句式中,可以去往省略和倒装的方向猜测?
umm...倒装这个东西,实际上就是为了躲避修饰部分太长而突出主句用的。所以,倒装和省略,都要求我们边读成分边看意思,进而通过语意来判断句中是否出现了倒装或省略。

DE 项中多了一个the会有影响吗?
mark C
回复所有人:解析中已更新平行的原因。
同问,to what extent,是不是有某个部分省略了?
对啦
同问to what extent
A 语法错误,discussion + have 错;
B 外延与内涵,focus在主干部分,have约束力弱,用动词形式;
C
D 同A;
E and前后要平行
C.[ whether Earth would grow warmer] and [to what extent ]
能理解 whether Earth would grow warmer是clause,但to what extent如何解释成clause?
楼上说的功能平行是什么意思?
求指教
功能平行@磨人的小妖精
whether Earth would grow warmer and to what extent这个是怎么平行的。。to what extent 为什么可以和一个句子平行。。
