第一条SC:GWD原题,一模一样,做过无数次了:
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 are fungi
The answer is C,
But I think fungi is parallel to Plants, should add "are" as Fungi are ... at acquiring carbon,
so should be A or B. DO not see what differenece between A and B though.
Any ideas? Please ......
