天山-5-29

Q29:
For protection from the summer sun, the Mojave lived in open-sided, flat-topped
dwellings known as shades, each a roof of poles and arrowweed supported by posts set in
a rectangle.
A. each a roof of poles and arrowweed
B. each a roof of poles and arrowweed that are being
C. with each being a roof of poles and arrowweed
D. with roofs of poles and arrowweed to be
E. with roofs of poles and arrowweed that are
Answer: A

Why? What is wrong with E?

I reckon the answer is E. A should not be the right answer because "each a roof" sounds awkward.

E. with roofs of poles and arrowweed that are

with是修饰谁呢？ flat-topped dwellings？ the Mojave？

正是这个只代原因使得大部分with打头的选项在GMAT里都错

我认为这个题的答案是A，独立主格each （is) a roof of poles and arrowweed

应该选A吧，这道题我没有看题目，光看选项，用两个“技巧”就得到A

1.前半句描述整体特征，后半句描述个体特征；也就是all---,each---结构，所以句中应该用each，这是GMAT考点，出现过好多次；详见刘振民《GMAT语法改错精解》P199-200

2.being出现在GMAT语法改错中必为错误选项，除了极少数的介词+being+Ved；这个是“公理”

我用google查了each a +N的情况，还是不少的
