题目内容
17．She likes milk for breakfast．（改为否定句）Shedoesn't like milk for breakfast．
分析 --她早餐喜欢喝牛奶．
--她早餐不喜欢喝牛奶．
解答 答案：doesn't like．考查否定句．句意"--她早餐喜欢喝牛奶．--她早餐不喜欢喝牛奶．"，主语是she第三人称单数，且含有实义动词likes，变否定句在实义动词前加doesn't．实义动词likes变原形like．答案是doesn't like．
点评 本题考查否定句．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．
