More than five thousand years ago, Chinesescholars accurately described the flow blood as a continuous circle controlledby the heart, but it went unnoticed in the West.
(A) but it went
(B) but it was
(C) although it was
(D) but the discovery went
(E) although the discovery was 本题选择D，请问E项是错在although上么？是否因为改变了原意不选E呢作者: infinitegrav 时间: 2010-1-21 06:30
although在这应该是和but可以等同的 我觉得主要问题是go unnoticed,这是个固定用法
