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,

the answer is C, but i choosed A. could anyone explain to me why the correct answer is A?

是宾语比较,A Plants are more efficient at acquiring carbon than are fungi 

at acquiring carbon 插在中间不通畅,而比较对象也不对等,且未划线部分 and converting it to energy-rich sugars 正好与 C. Plants are more efficient than fungi at acquiring carbon中at acquiring carbon对应. 且此时比较无歧义.

A 错是因为语序错吗？Plants are more efficient at acquiring carbon than fungi are

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,正如ls所说语序不好 造成歧义more efficient是说两部分的acquiring和coverting 如果是A这样 会让人误认为只是说more efficient at acquring 和C完美的表达没法比

B. Plants are more efficient at acquiring carbon than fungi, 比较歧义意味是carbon与fungi比较

C. Plants are more efficient than fungi at acquiring carbon,

D. Plants, more efficient than fungi at acquiring carbon, 没有谓语不成句子

E. Plants acquire carbon more efficiently than fungi,错误同B

这个题主要是读清楚句子结构就好办了 plants are more efficient at acquiring and coverting...那个in the form of carbon dioxide只是插入语，拿掉之后就清楚了很多。

这才对嘛， 而且后面的 AND DOING结构必须和 ACQUIRING 平行
