讲解几句英文句型
读了一下林肯的演讲辞,有几句话我没搞懂语法,
1.we have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live 这句话为什么两个that
2.it is for us,the living,rather,to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced.这句话中“which they who fought here have thus far so nobly advanced ”没理解,觉得句子缺少成分
3.that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion一点都没懂
本人英文不好,

Answer 1

we have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live
第一个that相当于 so that,表示结果或目的.
第二个是冠词,that nation.
--------------------------------------------------------------
it is for us,the living,rather,to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced.这句好复杂……
首先,who fought here 是修饰they,先忽略.
the unfinished work which they who fought here have thus far so nobly advanced
变成了
the unfinished work which they have thus far so nobly advanced
然后,这一句是说they have advanced the unfinished work thus far
那个so nobly 是形容他们这个行为的.
最后剩下的,it is for us,the living,rather,to be dedicated here to the unfinished work.就好判断了.
-------------------------------------------------------------
that from these honored dead
we take increased devotion to that cause
for which they gave the last full measure of devotion
they gave the last full measure of devotion for "that cause"
we take increased devotion to that cause from these honored dead
好像是这样,这句我不太确定
