She didn't agree with us and always __ her head in the meeting.

问题描述:

She didn't agree with us and always __ her head in the meeting.
A.shakes B.moves C.shook D.moved 请说明理由.

C 原句可分为She didn't agree with us.和 She always __ her head in the meeting.既然是didn't,则说明不同意是指过去,所以后半句自然也是制过去,再加上是并列句,前后时态一直.原形是shake,过去式是shook
