一、肯定陈述句
用来陈述事实，表示肯定，主要两大句式：主谓宾、主系表，There be也属于肯定陈述句。
1. 主谓宾（主语 + 实义动词 + 宾语）
主语发出动作，后面接动作的对象。
2. 主系表（主语 + 系动词 + 表语）
系动词包含be动词、感官动词(look / sound / taste / smell / feel)，后面接名词或者形容词，描述主语状态。
3. There be 肯定陈述句（表客观存在）
二、否定陈述句
在句子加入否定含义，表达“不、没有”。分4种情况，句型转换高频考点。
①句子含有be动词：be + not
be动词：am / is / are / was / were
②句子只有实义动词（无be/情态动词）
要用助动词do / does / did + not，后面动词变回原形
③句子含助动词（用于进行时、将来时、完成时）：助动词 + not
④句子含情态动词(can / should / will / must)：情态动词 + not
🔔必背否定缩写（考试直接填写）is not = isn't are not = aren't was not = wasn't were not = weren'tdo not = don't does not = doesn't did not = didn'twill not = won't can not = can't should not = shouldn't
