You(should not)eat too much junk food.It's bad for your health. 答案：1.must2.Could3.shouldn't 核心知识点： ust表示“必须”，没有过去式变化（表示过去“必须”仍用must)。 could用于委婉请求，语气比can更客气。 should not的缩写是shouldn't,意为“不应该”。 解析： 时间状语yesterday但“必须完成作业”是客观要求，must无过去式，用must。 委婉请求帮忙，用Could开头。 “不应该吃太多垃圾食品”，用缩写shouldn't。 1 高中北师大版 【选修4】 Unit11情态动词 真题三：句型转换（肯定句变否定句及特殊疑问句） (2024江苏南京期末，北师大版)按要求改写句子，每空一词。 They must clean the classroom after school..(改为否定句) Theythe classroom after school.
