More than 10,000 relics, ____ between 5,

问题选择题

More than 10,000 relics, ____ between 5,000 to 3,000 BC, ____ at Sanxingdui since it was first discovered.

A．dating back to, was dug up

B．dating back to, have been dug up

C．dated back to, has been dug up

D．dated back to, were dug up

答案

答案：B

第一空考查词组：date back to的用法，表示追溯到，只能用一般现在时的主动，所以做定语只能用现在分词，第二空考查主谓一致和时态，主语是More than 10,000 relics,谓语是复数，时间状语从句是since it was first discovered.所以用现在完成时，选B。
