比较级+than结构 和 as...as结构 的位置问题。。。
在prep上发现了两道题
According to a survey of graduating medical students conducted by the Association of American Medical Colleges, ---minority graduates are nearly four times more likely than are other graduates in planning to practice--- in socioeconomically deprived areas.
A.minority graduates are nearly four times more likely than are other graduates in planning to practice
B.minority graduates are nearly four times more likely than other graduates who plan on practicing
C.minority graduates are nearly four times as likely as other graduates to plan on practicing
D.it is nearly four times more likely that minority graduates rather than other graduates will plan to
practice
E.it is nearly four times as likely for minority graduates than other graduates to plan to practice
---Plants are more efficient at acquiring carbon than are fungi,--- in the form of carbon dioxide, and converting it to energy-rich sugars.
A.Plants are more efficient at acquiring carbon than are fungi,
B.Plants are more efficient at acquiring carbon than fungi,
C.Plants are more efficient than fungi at acquiring carbon,
D.Plants, more efficient than fungi at acquiring carbon,
E.Plants acquire carbon more efficiently than fungi,
正确答案分别是C C
这两道题都是主系表结构,没有宾语,且比较结构more than和as...as都是卡在系动词be之后,但第一道题中比较对象other graduates带了be动词,和minority graduates are平行,第二道题中比较对象fungi没有带be动词,是否是因为比较结构出现在主系表且在表语之前(第一题likely,第二题efficient)be动词可以省略?如果是因为省略了,这里be动词可省略的原因是因为和主语的be动词一样吗?
如果可以省略的话是不是意味着在比较结构的平行的要求和比较结构的省略的情况下,宁可省略也不要平行。。。。。?
然后延伸一下到主谓宾结构。。。
主语比较时,如果这两个结构出现在一个句子(主谓宾齐全)的主语后谓语前(如A more than B V O),应该不需要补出谓语。。
那么如果这两个结构出现在一个句子(主谓宾齐全)的宾语前谓语后(如A V1 more than B V2 O),V1和V2不同的情况下(假设V1 V2虽然表达不同但逻辑可比,因此AB具有可比性),V2应该不能省略?也不能用do替代?V1和V2相同的情况下,V2应该可以保留(遵循平行原则,但是会和V1重复?),也可以用do替代(避免重复),那是否可省略呢(像上面主系表结构一样比较对象省略be,但若省略B就和O紧挨,感觉很不合理。。)?
目前看到的关于这两个结构主语比较时的谓语省略的解释用的例子好像都是出现在宾语之后,即完整的主句之后。。。做题好像也没怎么遇到比较结构卡在宾语前的。。。。。
