A banked with dirt ot a height of
B banked with dirt as high as that of
C banked them with dirt to a height of
D was banked with dirt as high as
E was banked with dirt as high as that of
答案是A，我选的是D。我觉得如果选A 的话 its frameowork ...后面的句子不就没有没有动词了吗？。。
我想了半天也没有明白，希望牛人解答哈

49
Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to 1950.
A Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to
B Since 1990 the growth of the global economy has been more than that during 10,000 years, form when agriculture began
C The growth of the global economy since 1990 exceeds that which had been for 10,000 years from the beginning of agriculture
D The growth of the global economy since 1990 exceeds what it has been for 10,000 years, form when agriculture began
E The growth of the global economy since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture
答案是A ，但是我觉得B 读起来也没有什么错误呀。而且并不觉得它们之间存在着谁比谁更优的关系。。。想不明白。。请牛人解答。

不知道MM有没有看懂这句话的结构
这里主句是the single family house constructed by the Yana was conical in shape。was前是插入语。后面的its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt ot a height of three to four feet.这一堆是同位语。然后 banked with 是和 overlaid 平行的，都是用来修饰framework of poles， 不存在没有动词的问题哈。

1,overlaid and banked 都是谓语
2，B 二者比较中不对称，growth 和 that of during 会更好点

Q16 “ its framework of poles overlaid with slabs of bark, either cedar or pine, and banked with dirt ot a height of three to four feet.”  并不是一个独立的句子或者从句，是it+过去分词的独立主格结构
而且如果把这个独立主格结构变成一个完整的句子的话，就会变成RUN-ON错误了。（RUN-ON：用逗号、副词或者介词连接两个句子）
overlaid and banked 都是修饰framework的，而这个整体的独立主格又是解释它的shape的

Q49 首先B项改变了原文的重心，原文是比economy，B项变成了比较growth
       而且from是介词后面应该加名词
       再者说，即使from when 是正确的，为了达到平衡也应该是 form when... to when...的结构啊（当然啦这是不对的）
