一、核心知识
1. shuld + 动词原形 —— “应该”，表示建议或劝告，语气较温和。
Yu shuld preview the lessn befre class. (你应该课前预习。)
Yu shuld review after class. (你应该课后复习。)
2. shuldn't + 动词原形 —— “不应该”，表示劝告不要做某事。
Yu shuldn't waste time. (你不应该浪费时间。)
Yu shuldn't stay up late. (你不应该熬夜。)
3. had better + 动词原形 —— “最好”，语气比shuld强，表示强烈建议或警告。
Yu had better finish yur hmewrk first. (你最好先完成作业。)
Yu had better nt play cmputer games t lng. (你最好不要玩太久电脑游戏。)
否定形式： had better nt + 动词原形
Yu had better nt be late again. (你最好不要再迟到了。)
速记口诀：
shuld 应该语气缓，had better 最好强一点。
否定形式加 nt，动词原形紧跟其后。
提建议时看对象，礼貌得体是关键。
二、易错点提醒
易错1： had better 后误加 t。
❌ Yu had better t g nw. ✅ Yu had better g nw.
易错2： had better 否定形式写错。
❌ Yu had better nt t g. / Yu hadn't better g. ✅ Yu had better nt g.
易错3： shuld 和 had better 语气不分场合（对长辈/老师用had better不礼貌）。
对老师说：Yu had better explain this again. ❌ → Culd yu please explain this again? ✅
