题目内容
5.I think you should finish your homework first.(改为否定句)Idon'tthinkyou should finish your homework first.
分析 --我认为你应该先完成作业.
--我认为你不应该先完成作业.
解答 答案:don't think.考查否定句.主句含有think,且是第一人称的宾语从句.从句的否定形式通常要转移到主句上.一般现在时态,含义实义动词,主语是第一人称,变否定句在think前加don't.答案是don't think.
点评 考查否定句.通常是在be动词,情态动词后加not.一般现在时态,主语不是第三人称单数用don't,主语是第三人称单数用doesn't.一般过去时态用didn't.还有其它用法需要牢记.
