其实这个问题是有点傻的 只是我可能语法多年未review现在变得很生疏了吧。
上题:
Lesson42里面的:
It can take as long as eight days getting rope ladders rigged up and ______________before…………
a. to establish bases supplied b. supplying bases established
c. establishing supply bases d.bases established and supplied
排除a和d吧,答案中说c的话遵循了and的前后形式一致的规则,但是可不可以这么理解getting然后分割线,后面是getting sth. done 的两个部分,这样我认为b是对的,请指教b不对的原因吧~~~~ 拜高手的语法水平了。
那个我补充一下,原句是这个样子的
It can take as long as eight days to rig up rope ladders and to establish supply bases before…………
