Question

Do you still remember the key points that ___________ in his report? I don’t remember them all

1. A.
   referred to
2. B.
   were referred
3. C.
   he was referred to
4. D.
   were referred to

Answer 1

D
此题考查定语从句中从句缺少谓语。refer to 涉及，提到，句意：你仍然记得他在报告中提到的重点吗？我什么也没记住。题中that后为定语从句，that做主语，根据语境应用过去式，所以选D。
