① go; sleep ② health ③ well ④ shouldn't ⑤ teeth ⑥ has; will see

① should后接动词原形，第一空填go；Let's后接动词原形，第二空填sleep。② your后接名词，healthy的名词形式是health。③ feel后接形容词，well表示身体好，填well。④ 句意“你不应该吃太多蛋糕或饼干”，should的否定是shouldn't。⑤ lion有很多牙齿，tooth的复数是teeth。⑥ Sam是第三人称单数，have的第三人称单数是has；tomorrow morning表明用将来时，will see或is going to see，根据五年级内容用will see。
