Question

【题目】Do you remember ________at 9:00 yesterday?

A.what were you doingB.what you are doingC.what you were doing

Answer 1

【答案】C

【解析】

句意：你记得昨天九点你在做什么吗？

考查宾语从句。what were you doing你在做什么，疑问语序；what you are doing现在进行时；what you were doing过去进行时。根据句子结构可知，该空后引导宾语从句，从句中用陈述语序，先排除A；主句用的是一般现在时，从句中表示“昨天九点”正在做的事情，应用过去进行时态。故选C。
