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,
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。。）？
