I was studying about とき. I came to know that とき means "when" If used in following sentences:
Format: S1ときS2 (as per my own inference) (Please correct me if I am wrong)
S1- Adj(both i and na) and S2-Anything
S1 - Noun and S2-Anything
When S1 expresses a state and S2 anything
When S1 is a verb but is in ている form
Then I came across a concept, that when S1 is a verb (for now let us take action verb), the meaning will be different as per the tenses used:
私はご飯を食べるとき手を洗う （I wash my hands before I eat)
私はご飯を食べたとき手を洗う （I wash my hands after I eaten)
私はご飯を食べるとき手を洗った （I washed my hands before I ate)
私はご飯を食べたとき手を洗った （I washed my hands after I ate)
After this I came across a sentence:
In this sentence the translation in the same book was given "Mr. Matsumoto always watches TV when he eats"
So, my queries are the following:
- Does this sentence (Matsumoto sentence) mean, Matsumoto always watch TV before he eats?
- If the sentence means what the book says i.e. "Mr. Matsumoto always watches TV when he eats" wasn't ている supposed to be used to make mean (when it was happening) i.e. 食べている rather than 食べる?
- Has, いつも something to do with the sentence making it a "state of being" thereby, allowing the use of "when"?
- Does this S1 Verb (action) condition i.e. right before or right after apply in case S2 is adjective/noun; E.g. 私は本を読むとき静かな (thereby, meaning I am quiet before I study?); 私は本を読んだとき静かな (I am quiet after I study (As in context of I am in state of silence after I study); and 私は本を読読んでいるとき静かな(meaning I am quiet when I am studying)? or is there any other rule?
