보다 is about where you park your eyes

Where the picture shows up in 보다

1. 1

   eyes on the screen

   어제 그 영화 봤어요?

   eo-je geu yeong-hwa bwa-sseo-yo

   Did you see that movie yesterday?

2. 2

   eyes stuck to the bag

   잠깐 가방 좀 봐 주세요.

   jam-kkan ga-bang jom bwa ju-se-yo

   Could you keep an eye on my bag for a second?

   봐 주세요 can mean 'look at it' or 'watch over it'. With a bag it means guard it.

3. 3

   try it and see

   이거 한번 먹어 보세요.

   i-geo han-beon meo-geo bo-se-yo

   Go on, have a taste.

   -아/어 보다 means giving something a try to see how it turns out.

4. 4

   how it looks to you

   제가 보기에는 좀 비싼 것 같아요.

   je-ga bo-gi-e-neun jom bi-ssan geot ga-ta-yo

   To me it seems a bit expensive.

5. 5

   you go through it

   내일 면접 보러 가요.

   nae-il myeon-jeop bo-reo ga-yo

   I have an interview tomorrow.

   Exams and interviews take 보다, never 하다: 시험을 봐요.
