Positive, assured, and reassured all describe a good mental state, but the source differs. Positive describes a hopeful, optimistic attitude about a situation or the future. Assured describes self-confidence in one's own ability. Reassured describes relief felt after someone else removes a specific worry.

这三个词都能表示某种积极的心理状态，但来源和方向不同：positive 指对情况或未来持乐观态度；assured 指对自身能力或表现的内在自信；reassured 指因他人的安慰或保证而消除了先前的担忧，感到放心。这里不比较 positive 表示“确定的”或数学中“正数”的义项，也不比较 assured 表示“确定的、有保证的”这一义项。
