In your element 表示正在做喜欢又擅长的事，因此感到自信、愉快。Your 要随人称改变：I'm in my element，she's in her element。相反的 out of your element 表示在陌生情境中感到不自在。这个习语适合 IELTS Speaking；作文里用 feel confident and comfortable 更直接。
什么情境适合说 in your element？

本次检查比平时稍久，完成后反馈会自动显示在这里。
be + in my/your/her element (+ when + clause); feel/be + out of your element
- Put my dad in a kitchen full of hungry guests and he's in his element.
- Our new colleague was in her element when she presented the design to the clients.
- I was completely out of my element at the formal conference dinner.
修改原因
修改前I didn't know anyone at the party and felt not in my plate.
修改后I didn't know anyone at the party and felt out of my element.
Not in my plate 不能让英语读者理解为“不自在”。描述在陌生环境里不舒服、不适应，应说 out of my element。修改只替换了这个短语。
In your element 不只是感到舒服，还强调正在做擅长并且喜欢的活动。如果只是想说在某处感到轻松自在，可以用 feel at home：I felt at home with my host family from the first day。
动手练习
Lisa loves children and has worked in a nursery for ten years, so at her nephew's birthday party with twenty kids she was ___.
查看答案
in her element — Lisa 喜欢孩子，也有多年照顾孩子的经验，所以在二十个孩子中间会如鱼得水，应选 in her element。Out of her element 会表示她感到不自在、格格不入，与语境相反。
写一项让你感到如鱼得水的活动。说出是什么，并解释为什么你很擅长。
I'm in my element when I'm cooking for friends, because I've been experimenting with recipes since I was twelve.
