在一些英语测试题中，我们常常见到“将肯定句改为否定句”这样的题目，你会改吗？下面对此作一简单归纳，供大家学习时参考。一、否定句的一般改法：１．如果句中的谓语部分含有“be动词”或“助动词、情态动词+行为动词”，改为否定句时，一般在be动词／助动词／情态动词后面加not。例如：He is a worker．→He isn’t a worker．They will have a meeting．→They won’t have a meeting．We have finished our work．→We haven’t finished our work．He can mend the computer．→He can’t mend the computer．
In some English test questions, we often see the problem of changing an affirmative sentence to a negative one. Will you change it? The following is a brief summary of this for everyone’s reference. First, the general reform of negative sentences: 1. If the predicate part of the sentence contains “be verb” or “auxiliary verb, modal verb + behavioral verb”, when it is changed to a negative sentence, not verb/auxiliary verb/modal verb is usually followed by not. For example: He is a worker. →He isn’t a worker. They will have a meeting. →The won’t have a meeting. We have finished our work. →We haven’t finished our work. He can mend the computer. →He can’t mend the computer.
