66. Archaeologists in Egypt have excavated a 5,000-year-old wooden hull that is the earliest surviving example of example of a “built” boat—in other words, a boat constructed out of planks fitted together—and that thus represents a major advance, in terms of boat-building technology, over the dugout logs and reed vessels of more ancient vintage.

A. together—and that thus represents

B. together—and this has represented

C. together, and it represents

D. together that was representing

E. together to represent

 

A: correct

B: this 不能单独做主语；and 和前面不平行

C: and 和前面不平行

D: that指代boat错；没必要用过去时

E: 改变原文句意

 

注意：

1、             that do A … and that do B是优选结构

2、             注意时态的选择

原文中两个破折号是什么意思？是表示解释吗？如果这样，那么做题的时候，可以跳过不看了？

我认为a选项不对，因为a选项中that感觉是指代boat，如果有and在that前边的化，that就不是定语从句的指代词，不能够代表boat，有and以后，and that 和前半句是并列关系，那这个时候，that是指的什么呢？做什么用呢？

还请nn们帮我看看

破折号一定要有前后两个吗？C为什么不对
