Question

【题目】- Why didn't Peter ______ his homework?
- He said he had lost his workbook. I think it's an excuse.
A.does
B.doing
C.do
D.did

Answer 1

【答案】C
【解析】句意：——为什么彼得没有做作业? ——他说他的作业本不见了。我认为这是个借口。do 由Why didn't Peter可以看出此处考察的是一般过去时, 一般过去时的否定疑问句, 助动词didn't 提至主语前, 后面的动词要还原为原型, 做家庭作业是do one's homework, 所以答案选C。
