〜かわりに（代償交換条件）
N3
V（辞書形）+ かわりに N + のかわりに
「〜かわりに（代償交換条件）」的意思类似于中文里的「作为代替」或者「作为交换条件」。
它用来表示在某种情况下，为了得到或做某事，必须放弃或做另一件事情。
可以理解为一种条件交换的关系，牺牲一方以换取另一方的利益。
比如，你可以说:我帮你做作业，你帮我洗碗，这里的「帮你做作业」就是代替条件，换取了对方的洗碗。
The grammar pattern "~かわりに" is used to express a condition of exchange or substitution.
It is similar to saying "instead of" or "in exchange for" in English.
This pattern is used when one thing is replaced by another, or when one action is done in place of another.
For example, if you say "昼ご飯のかわりにフルーツを食べた" (Hirugohan no kawari ni furuutsu o tabeta), it means "I ate fruit instead of lunch" or "I had fruit in place of lunch", indicating that you chose to eat fruit as a substitute for lunch.
