The discovery of twenty-one ceramic dog figurines during the excavation
题目分析：
略。
选项分析：
A选项：That twenty-one ceramic dog figurines were discovered是主语从句，其应该改为名词短语The discovery of twenty-one ceramic dog figurines，这点考查了名词和从句的区别。用之于本题，显然地，在逻辑上能发出“两倍了我们已知的工艺品的数量”的只能是“发现”这个事件，我们只能说在“发现21个工艺品”这个事件发生的时候，它两倍了工艺品的数量，这个时间之后，任何时候我们都不能这么说（例如，在一年后，可能已经发现了很多个类似的工艺品，这个发现自然就不能2倍工艺品的数量了）。一个事件必然是有时间终止点的，因此应该用名词短语。
同理，excavating需改为名词excavation，这点考查了名词和ing的区别。用之于本题，由于excavate这个动作发生在during这个介词短语中，显然excavate在本句中不能脱离自己发生的时间（during本来就表示主句的发生时间在excavate这个动作的发生时间段内），因此，during身后只能用名词短语。
B选项：按照本选项所写，谓语动词has nearly doubled的主语的核心词变为Twenty-one ceramic dog figurines。但在逻辑上，发出两倍这个动作的只能是“发现”这个事件，不能是figurines本身。
C选项：本选项错误在原理上和选项(A)相同。
D选项：本选项错误同选项(B)。
E选项：Correct. 本选项在语法和逻辑上均是正确的。
B主谓不一致排除
RON的解释也是 discovery发出的这个动作，他说是一种subtle difference要自己体会登录 或 注册 后可以参加讨论
在亚利桑那州坦佩市一个有 1000 年历史的 Hohokam 村庄的挖掘过程中发现了 21 个陶瓷狗雕像，使已知存在的这些文物的数量
发出两倍这个动作的只能是“发现”这个事件，不能是figurines本身
而且要思考及时性，当下是double，后面就不一定了
ing和动名词的差异：过程和结果；结束和未知是否结束；ing通常表示主句主语是动作主语，动名词则没有这个意义。
如：I want to learn about adopting a dog,表示我想去收养一只狗；I want to learn about the adoption of a dog,不表示是我要去收养一只狗，可能是我去研究其他人如何收养狗这件事情。所以如果动作发起的主体不知道的话，优先用动名词。
显然只有一件已经完成的事情以及已经确定数量的figures才会导致某物的数量翻倍，用名词。
名强调结果，一般指事情已结束；从句和ing以谓语动词为核心，强调动作的过程，一般看不到动作的终止迹象和时间点
The discovery of twenty-one ceramic dog figurines 发现了21个雕塑使现有数量doubled；
That twenty-one ceramic dog figurines were discovered强调发现的过程使现有数量doubled
--> this is a correct sentence. in other words, you are normally late, and so the fact that you arrived on time was a surprise.
your arrival on time today was a surprise --> this isn't as good, because your arrival wasn't a surprise. the surprise was the fact that you actually showed up on time.

your arrival on time today was a surprise --> this isn't as good, because your arrival wasn't a surprise. the surprise was the fact that you actually showed up on time.
以及注意A的错点：the weirdness of the "that..." construction in (a) isn't grammatical. it's perfectly fine to use "that" + clause as the subject of a sentence, provided that you are trying to refer to some fact as an abstraction, rather than to an actual action.
不知道这么理解对吗？毕老师
Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
