I've been working through Chapter 5 (course 2) and am still a bit confused on when to use GA and when to use WO.
Consider the following example where I have to answer the question:
ときどき にほの おさけを のみますか
Which of the following is correct, and more importantly why? The first answer that came to mind was 1. but maybe I should use WO because it's のみます? However if I used すき, would it then be GA? I'm confused!
Q1: なにが すきですか。(NANI GA SUKI DESUKA) = What do you like? A1: おすしが すきです。(OSUSHI GA SUKI DESU) = I like sushi.
Q2: なにが ほしいですか。(NANI GA HOSHII DESUKA) = What do you want? A2: とけいが ほしいです。(TOKEI GA HOSHII DESU) = I want a watch.
When using "like" or "want", the subject particle が (GA) is used after the item or person that is liked or wanted.
However, if you are using verbs such as "eat" or "drink", you need to mark what you are eating/drinking with を (O).
Q3: なにを たべますか。(NANI O TABEMASUKA) = What will you eat? A3: ごはんを たべます。(GOHAN O TABEMASU) = I will eat rice.
Q4: ときどき、にほんの おさけを のみますか。(TOKIDOKI NIHON NO OSAKE O NOMIMASUKA) = Do you drink Japanese sake sometimes? A4: いいえ。でも、ときどき ビールを のみます。(IIE. DEMO TOKIDOKI BIIRU O NOMIMASU) = No, but I drink beer sometimes.
