Questions & Answers about jeoneun jigeum sueobe jipjunghago isseoyo.

Why is 저는 used instead of 나 or 제가?

저 is the polite–humble first-person pronoun, whereas 나 is informal and can sound rude in polite conversation. The particle -는 marks 저 as the topic of the sentence. If you used 제가, you’d be marking 저 as the subject with -가, which shifts the nuance from “as for me…” (topic) to simply “I…” (subject focus). In polite speech about what you’re doing right now, 저는 is the most natural choice.

What does 지금 add to the sentence, and can I leave it out?

지금 means “now” or “right now.” It emphasizes that the action is happening at this very moment. If you omit 지금, the sentence 저는 수업에 집중하고 있어요 still means “I am concentrating on the class,” but it’s less clear that you mean “at this exact moment.”

Why is it 수업에 집중하고 있어요 instead of 수업을 집중하고 있어요?

The verb 집중하다 takes the locative/target particle -에, not the object particle -을/를. In Korean, many verbs of mental focus or movement use -에 to show the thing you’re focusing on or moving toward. So you always say ~에 집중하다 (“to focus on ~”), not ~을 집중하다.

What’s the difference between 집중해요 and 집중하고 있어요?
