题目内容
6.Tom had dinner with his family in a restaurant last night.(改为否定句)Tomdidn't havedinner with his family in a restaurant last night.
分析 汤姆昨天晚上和家人在饭店吃晚饭.
汤姆昨天晚上没有和家人在饭店吃晚饭.
解答 答案:didn't have.原句中的had是have的过去式,表示吃…,实意动词,否定句借助于did后加上not,缩写成didn't,后面的had还原成原形have,故答案是didn't have.
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:
