1、（2）教学目标：祈使句和情态动词 should、had better 的用法。（3）教学重难点：祈使句否定形式及情态动词 should、had better 的用法（4）学习与交流：当我们给他人提建议时，可以用 had better 和 should， 表示“最好”或“应该”做某事， had better 的语气比 should 强一些。如：You had better water the flowers. All of us should take part in this activity.注意 had better 和 should 都是情态动词，后接动词原形，而且均没有人称和数的变化。
2、had better 中的 had 常缩为 d 如： Wed better leave before it rains. Youd better go home now.had better 和 should 的否定形式是：had better not 和 should not/shouldnt.如： You had better not play computer games now.He shouldnt be late for school again.（5）典型题例1.
