They did their homework at school yesterday afternoon．Theydidn't dotheir homework at school yesterday afternoon．题目和参考答案——青夏教育精英家教网—

题目内容

7．They did their homework at school yesterday afternoon．（改为否定句）
Theydidn't dotheir homework at school yesterday afternoon．

分析昨天下午，他们在学校做作业．
昨天下午，他们没有在学校做作业．

解答答案：didn't do．根据yesterday afternoon可知，本句是一般过去时．根据 did their homework 可知did是实义动词，需要用助动词did来帮助否定；又根据did后面用动词原形，故应填didn't do．

点评本题考查否定句的变法，做本题时比较容易受did的影响，导致只填didn't．
