Question

This old building is said _____ two years ago and a new high building now stands where the old one used to lie.

A. to have puller down                              B. be pulled down        

C. pull down                                             D. to have been pulled down

Answer 1

D

解析:

主要测试固定结构和语态。句子中：be said to do 属于固定结构，由此先排除：B和C。句子中动词短语：pull down “推到”，和主语the old building 属于被动关系，所以选择：to have been pulled down。
