日本語のぶんぽうのしつもんがありまあす。 Hello, community of italki. I have a question reguarding the japanese grammar particles "たり" and "しか".　I was wondering if there's any problem combining "から” or "とき" with these. So I know I can say: あしたのよるにりょうりするしかありません。 (My only option is to cook tomorrow afternoon.) But could I say: あさにしごとがあるからあしたのよるにりょうりするしかありません。 (Because I have work in the moring, my only option is to cook tomorrow afternoon.) Or could I say: あさにしごとをするときりょうりするしかありませんでした。 (When I would work in the morning, my only option was to cook in the afternoon.) And also when using "たり", could I combine "とき” and ”から”? おかねがあんまりないからたべたり、こうえんにいったり、なにもかったりしません。 (Because I really didn't have any money, I didn't eat, didn't go to the park, and didn't buy anything.) おかねがあるときたくさんたべたり、たくさんのんだり、たくさんかったりできます。 (When I have money, I'm able to eat a lot, drink a lot, and spend a lot.) I would appreciate any answers, or corrections on this. Thank you.
