否定句的例子
否定句是表示否定的句子。否定句是全句谓语中心语前具有否定性状语，而对事物作出否定判断的句子，必须有否定词，古代汉语中否定词可以是副词“不”、“弗”、“毋”、“勿”、“未”、“否”、“非”，可以是动词如“无”。
1、单纯否定句。是指否定句中只有一个否定词。如，天空不是绿色的。又如，今天他不回来了。再如，今天的天气没有太阳。
2、双重否定句。双重否定句是指一句话中有两个否定词，双重否定表示。如，我不得不承认这个东西是我的。所表达的意思就是我承认这个东西是我的，是肯定意思。
肯定句和否定句：
1、定义。对事物作出否定判断的句子叫否定句。
2、肯定句和否定句的转换。肯定句和否定句句式转换的原则是不能改变原意。转换的要点是否定词的运用：保持原意则加两个否定词；变成相反的意思则加一个否定词。另外要注意反问句也是一重否定。
3、肯定句转为双重否定句的方法。将肯定句改为双重否定句是只需在恰当的位置加入“不可能不”“不得不”“没有…不”“非…不可”等双重否定词。
