What were you doing at eight last night？？

Answer 1

分析 What were you doing at eight last night？昨天晚上八点你在做什么？

解答 答案：What were you doing at eight last night？．
首先结合提示词和标点符合明确所要组合的句子是一个特殊疑问句，疑问词是what，组合成的句子的句意是"昨天晚上八点你在做什么？"，时间状语是at eight last night；用过去进行时，构成是was/were+动词的现在分词，故答案为：What were you doing at eight last night？

点评 做连词成句这种类型的题，首先确定句子类型，如：陈述句、疑问句或感叹句等，然后根据所给单词，明确主语、谓语等句子成分，在确定句意的前提下结合语法知识组合句子．
