Circle the odd ones.Then give your reasons.
1. 圈出habit；原因：height（身高）、size（尺寸）、weight（體重）都和身體外在的“度量/特征”相關，habit（習慣）是行為模式，類別不同。
2. 圈出enjoy；原因：joy（喜悅）、happiness（幸福）、fun（樂趣）都是名詞表情緒/感受，enjoy是動詞（享受），詞性不同。
3. 圈出smart；原因：angry（憤怒的）、disappointed（失望的）、sad（悲傷的）都表負面情緒，smart（聰明的）是中性特質，情感色彩不同。
4. 圈出watch；原因：appear（顯得；出現）、look（看起來）、seem（似乎）都可表“感官/推測”，是近義詞；watch（觀看）側重“主動看動作”，語義不同。
5. 圈出bread；原因：honey（蜂蜜）、milk（牛奶）、juice（果汁）都屬“飲品/流質食物”，bread（面包）是固體主食，類別不同。
