Question

【題目】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：你記得昨天九點(diǎn)你在做什么嗎？

考查賓語從句。what were you doing你在做什么，疑問語序；what you are doing現(xiàn)在進(jìn)行時(shí)；what you were doing過去進(jìn)行時(shí)。根據(jù)句子結(jié)構(gòu)可知，該空后引導(dǎo)賓語從句，從句中用陳述語序，先排除A；主句用的是一般現(xiàn)在時(shí)，從句中表示“昨天九點(diǎn)”正在做的事情，應(yīng)用過去進(jìn)行時(shí)態(tài)。故選C。
