go outdoor 定 go outdoors？
✗ 你會咁寫
Parents should lead their children to go outdoor at weekends.
✓ 應該係
Parents should lead their children to go outdoors at weekends.
去戶外活動係講去邊度，所以要用副詞「outdoors」。形容詞 outdoor 只可以擺喺名詞前面，例如 outdoor activities。

點解你會咁寫
中文「戶外」一個詞用晒兩邊，英文分開兩個。記法簡單：後面跟住名詞用 outdoor，冇名詞跟住用 outdoors。

✓ I enjoy outdoor activities.
