That twenty-one ceramic dog figurines were discovered during the excavating of a 1,000-year-old Hohokam village in temple, Arizona, has nearly doubled the number of these artifacts known to exist. A That twenty-one ceramic dog figurines were discovered during the excavating B Twenty-one ceramic dog figurines were discovered at the excavating C Discovering twenty-one ceramic dog figurines at the excavating D Ceramic dog figurines,twenty-one of which were discovered during excavating E The discovery of twenty-one ceramic dog figurines during the excavation 正确答案E我选了A。对于E我有几点疑问： 1.E说的是发现导致文物的数量翻了一倍。 A说21个瓷器被发现这件事导致文物数量翻倍。 我觉得A这件事情更适合做led的动作发出者。 2. excavating和excavation excavating表示动作持在做。 excavation表示一种什么样的状态呢？ 这两个词在这句话里意思/逻辑上有没有什么区别？
