【选对】 我认为这里用which was officially known as 是对的,假如用known as 可能会想成形容construction
which refers to Colosseum
was officially known as应该是修饰Colosseum的,用非限定性定从。a 的句子有两个谓语了
1) which就近修饰,修饰RC 而直接用known as是用来修饰construction的 2) begin-began-begun
A中是began不是begun,不是过去分词,不是分词作状语 而C中根据拘役,是开始与结束并列,所以要加and
began was completed平行
began 和 was completed 平行
以为是错的。以为began...,and was completed会被包含在which从句里面。但其实并不是呀
which 就近修饰所以是正确的
平行结构,第一个不省略,后面平行的省略
which此时了Colosseum
during the reign of Vespasian是一个插入语,如果去掉插入语的话原句仍然应该是一个完整的句子,如果没有了and,began in A.D. 69和was completed a decade later是联系不起来的。
