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．
