题目内容
2．Her father bought a new bike for her．（改为否定句）Her fatherdidn't buy a new bike for her．
分析 她的爸爸买了一辆新自行车给她．
她的爸爸没有买一辆新自行车给她
解答 答案：didn't buy．
原句是一般过去时，bought是buy的过去式，故借助于助动词did构成否定，后加动词原形buy，故答案是didn't buy．
点评 含有be动词，情态动词或者助动词have/has的句子转化成否定时在其后面加上not，一般实意动词的否定式，通常应根据不同时态和人称在实意动词之前加don't，doesn't，didn't等．
