B 解析：考点为 had better 的否定结构。had better not 后接动词原形，A 选项 staying 是动名词，C 选项多了助动词 don’t，D 选项多了 to，均错误。 1. A 解析：考点为 had better 的肯定结构。根据句意 “考试很重要”，需用肯定式，had better 后接动词原形，排除 B、D；C 选项否定式不符合语境。 1. C 解析：考点为 had better 的一般疑问句。结构为 “Had + 主语 + better do?”，其他选项无此用法，故选 C。 1. A 解析：考点为 had better 的固定搭配。无 “would better” 这一结构，排除 C、D；had better 后接动词原形，排除 B，故选 A。 1. C 解析：考点为 had better 的否定结构。根据句意 “不要浪费水”，需用否定式 had better not，A 选项肯定式不符合语境，B、D 结构错误。 （二）句型转换题 1. had better not 解析：否定句直接在 had better 后加 not，结构为 “had better not + 动词原形”。 1. Had; better 解析：一般疑问句将 had 提前，主语后接 better + 动词原形，句末用问号。 1. had better 解析：原句是否定式 “不要吃垃圾食品”，改为肯定句需表达 “最好吃健康食品”，用 had better 的肯定结构。 （三）翻译题 1. We had better review what we have learned on weekends. 解析：“复习所学的知识” 译为 review what we have learned，“在周末” 用 on weekends（课标词汇），符合 had better + 动词原形结构。 1. You had better not play mobile phones in class. 解析：“玩手机” 译为 play mobile phones（课标词汇），“在课堂上” 用 in class，否定结构为 had better not + 动词原形。 1.

We had better spend half an hour practicing oral English every day. 解析：“花时间做某事” 译为 spend time doing sth（课标短语），“英语口语” 译为 oral English，符合 had better + 动词原形结构。 学科网（北京）股份有限公司 $
