the iroquois were primarily planters, but supplementing their cultivation of maize, squash, and beans with fishing and hunting,
C) and even though they supplemented
D) although they supplemented
答案选D 我会做,但是OG对C的解释是:even though creates a sentence fragment. 这让我很是不解。 为什么句子不完整呢? 我看 even though they supplemented ..... 是个完整的句子啊,谁能帮帮我呢?谢谢~作者: winny0821 时间: 2011-6-28 20:52
