摘要：问[938][joycesue17@sina．com]精读课文中有这样一句：①E Even though his behaviour wasn＇t particularly courageous, on balance I agree with what he did, or rather did not do. ．请问这是什么句子结构？or rather是什么意思？阅读时还有一句：② The cheapest way to explore the ocean floor, however, may be with the freefloating AUVs. ．这里的AUVs指什么？又taxidancer是什么意思？谢谢。
