专项突破 句型-2021【通城1典】小学英语总复习配套PPT（人教PEP版）

PEP版 第二部分 专项突破 五　句 型 (一) 陈 述 句 1. 陈述句的功能及结构特征 陈述句是用来说明一个事实的句子，其主要功能是传递信息、提供情况，用来肯定或否定某个事物、某件事或某种情况。陈述句的结构特征通常是主语在前，谓语在后，读时用降调，句尾用句号。如： My mother is going to buy me a new dress. 我妈妈将给我买一条新的连衣裙。 2. 陈述句的肯定句变为否定句 (1) 含有be动词或情态动词时，在be动词或情态动词后直接加not。如： She is a teacher.→She is not a teacher. You can play here.→You can't play here. (2) 含有实义动词时，在实义动词前加助动词don't, doesn't或didn't，后面的动词要用原形。如： I do my homework in the evening. →I don't do my homework in the evening. (3) 否定式的缩略形式 is not ＝ isn't　　　are not ＝ aren't was not ＝ wasn't were not ＝ weren't cannot ＝ can't could not ＝ couldn't do not ＝ don't does not ＝ doesn't did not ＝ didn't will not ＝ won't [典例精析] (2020•义乌改编)根据句意，完成句子。 He ________ a trip to Beijing last winter holiday. 解析：take a trip意为“旅行”。由时间状语last winter holiday可知，此处需填动词take的过去式形式，即took。 答案：took [小试身手] 改为否定句。 You can cross the road now.
