主语:通常是人(只有人能“下决心”);
结构:主语 + resolve/resolved/resolves(时态变化) + to do sth.(不定式作宾语);

resolve to do sth. vs. decide to do sth.:
"decide"更侧重“做出选择”(可能较随意);"resolve"更强调“坚定的决心”(经过深思熟虑后的承诺)。

I resolved to eat healthier starting today.(我决心从今天开始吃得更健康——坚定承诺)。
"resolve to do sth." 是表达“坚定决心”的正式短语,适用于描述“立志改变、实现目标”的场景,核心是“firm decision(坚定决定)”。
