forests supply pharmaceuticals and provide employment ...两个动词supply和provide需要平行
choice b, supply 1)pharmacy and 2) source of building material and firewood意思变成了两个宾语并列。导致了supply和are providers之间没有任何连词
choice a,b,c都是recognize (V) + rental rates (O) + 宾补( C) 的结构,但是由于recognize的约束力本身比较弱,所以宾补的形式出现并不合适。
choice d, within the city limits 介词宾语作状语修饰动词charge,但是意思上应该是作为定语修饰名词property
based on,It would apply to the women themselves (the following subject).The
women are not based on ancient records, so that's wrong.
according to the records是可以接受的。问题出在choice c, the robe that they used to dress the statue,暗示了这个robe像是一个工具; 而choice d, 完整的传递出了女人们把robe穿在statue身上的意思
注意句尾逗号和and的区别!!这里没有注意到!句尾!
