They carried on ------------ though it was darkA workB with a work C workingD to work
问题描述：
They carried on ------------ though it was dark
A work
B with a work
C working
D to work
答
even though
那就选C， doing
答
空格填 even
even though 是 “即便、尽管”的意思
carry on 是按照计划继续进行、执行的意思。
They carried on even though it was dark.
即便很黑很暗，他们依旧（按计划）进发。
补充：既然有了选项那就再探讨下吧。 反正 even though 和 though 意思并无不同。
要是 B 选项答案是 with their work 的话，我会毫不犹豫选 B.
但是 carry on 的确带有 continue 的同义成分，后面加 working 语法上正确，也合情理。
相对而言，with a work 的措辞有点儿别扭。
单选题，即便有两个都说得通的选项，也必须选出“最佳”答案。斟酌过后，我还是觉得应该选择 B. with a work.
答
选C,CARRY ON的ON 是介词,介词后用动词ing
