The Iroquois were primarily planters, but supplementing their cultivation of maize, squash, and beans with fishing and hunting. (A) but supplementing (B) and had supplemented (C) and even though they supplemented (D) although they supplemented (E) but with supplementing 答案选D没有问题 想问下C中如果把and去掉的话,会是正确的吗? 答案中解释的even though creates a sentence ragment.什么意思呀,eventhough和although不是一样的用法么?
可是我觉得they是不能省的 比如 Even though he tried, he still lagged behind other runners.尽管他努力了,仍落在其他赛跑者之后。We mustn't let up, even though we're winning.我们即使快赢了也决不可松劲。 这样看来 eventhough 后面也要加完整的句子 不知道能不能这样理解
