Question

【题目】Susan ________ her homework at school every weekend.

A. don't B. don't do

C. doesn't D. doesn't do

Answer 1

【答案】D

【解析】句意：Susan每个周末不在学校做她的家庭作业。don't不，助动词；don't do不做；doesn't助动词，是三单形式；doesn't do不做。句中的主语Susan是第三人称单数，助动词应用does，故先排除A和B。do one's homework是固定短语，做家庭作业，doesn't后面用动词的原形，故应选D。
