Hayley教口語，“心思不在…上”用英語怎么說？

If your heart isn't in it, you do not feel interested or enthusiastic about something.

心思不在…上面，對(duì)…不感興趣

I tried to look interested, but my heart wasn't in it.

我試圖裝出感興趣的樣子，可是我的心思完全不在這上面。

We could tell that Sally's heart wasn't in it when she tried singing jazz, so we said she should stick to pop songs.

我們看出來薩里在嘗試唱爵士樂時(shí)心不在焉，所以我們認(rèn)為她應(yīng)該去堅(jiān)持流行歌曲。
