大全95

95.  Although some officials noted that using machines for farming in China costs more than traditional hand cultivation, the mechanization of farming in the village of Long Bow doubled the corn yield while the previous year’s costs were cut in half.

(A) mechanization of farming in the village of Long Bow doubled the corn yield while the previous year’s costs were cut in half

(B) mechanization of farming in the village of Long Bow doubled the corn yield while cutting costs to half those of the previous year

(C) mechanization of farming in the village of Long Bow doubled the corn yield as cost were cut to half of the previous year’s

(D) farming mechanization in the village of Long Bow doubled the corn yield as it cut in half the previous year’s costs

(E) farming mechanization in the village of Long Bow doubled the corn yield

答案是B。 我想问的是half何those是什么关系？我感觉他们中间没有of很不舒服的，所以没选！请解释，谢谢

half后面可以直接接名词。

Longman：

Over half of the children live in one-parent families.
Only half the guests had arrived by seven o'clock.                                                                  

It's only half the size of a normal violin.

建议不要琢磨答案为什么对。多把选项放在一起比较，因为现在选项越来越相似。想靠完全弄清所有语法用法来做对题目是不可能的。这部分其实重点考行文逻辑性和对称性，而非语法正确与否。

hitler提出的排除法的確是很好的方法,

另外,可以請問一下,為什麼"the previous year's costs"必错呢?

Thanks...^_^

一般有生命的采用's的所有格。非生命用of, 此题应用 the costs of the previous year
