无论是去面试，还是第一次约会，我们总希望能在各种场合给别人“留个好印象”。

“印象”是指某人或某事给你的感觉或看法（a feeling or an opinion that you get about somebody/something, or that somebody/something gives you），“留个好印象”可以翻译为“put best foot forward”，这个英文习语可以表示“To try to act as an ideal version of oneself, typically to try to impress others”。

例句：

如果你想要得到这份工作的话，你真的需要在面试中留个好印象。

You really need to put your best foot forward in the interview if you want to get this job.

每当我和别人第一次见面时，我都尽量留个好印象。

I try to put my best foot forward whenever I meet someone for the first time.
