(为我修理架子) ______ ______ a picture on the wall, please. (张贴) the walls . (将墙壁涂成蓝色) (2) 祈使句的否定形式： “Don’t + 动词原形” 开头 e.g. the cat. (不要涂色) 2. 情态动词had better 情态动词had better表示一种建议和劝告，意思是“最好”、“还是……好”。 意思与should相近，但语气比should强烈。 (1)肯定句形式：“主语+had better+动词原形+……” e.g. It’s raining outside.______ _______ _____ _____ (你最好穿上) your raincoat． (2)否定句形式：“主语+had better not+动词原形+…” e.g. You_____ _____ ______ _____ _____ _____ (最好别叫醒我) before 6 a.m. 注：人称和数的形式：had better中had无人称、数和时态的变化。 缩写形式：had better可以与作主语的人称代词缩写。 如：you had better = you’d better we had better = we’d better … e.g. 你最好耐心点，这孩子只有一岁大。 _______ ______ be patient, the baby is only one year old.
