人教版小学英语六年级期末复习知识分类(九) (陈述句) 知识梳理 陈述句：用来陈述一个事实或者说话人的看法的句子，它包括肯定句和否定句。 一、肯定句变否定句的基本方法 1.含有be动词的句子，变为否定句时只需在be动词后加not。 (1)I am from Guangdong.--I'm not from Guangdong. (2) Mike is singing now.--Mike isn't(is not) singing now. (3) It was a fine day.--It wasn't(was not)a fine day. 2.含有情态动词的，变为否定句时只需在情态动词之后加not。如：. (1)I can speak English.--I can't(can not) speak English. (2) You should rest now.--You shouldn't(should not) rest now. 3.含有实义动词的，变否定句要根据动词形式选用助动词do的相应形式，如动词为原形，用don't+动原；动词是三单，用doesn't+动原；动词是过去式，用didn't+动原(do, does, did),并在其后加not。如: (1)I like listening to music.--I don't like listening to music. (2) She speaks Chinese well.--She doesn't speak Chinese well. (3) Amy stayed at home.-Amy didn't stay at home. 注意:some, something用于肯定句, any, anything用于否定句; too用于肯定句, either用于否定句。 练习检测 一、按要求写句子。(1-5题改为否定句，6-10题改为肯定句) 1. This is a desk. This a desk. 2.
