1. Explain it simply
稍微 means 'slightly, a little'. It says an action or change happens only to a small degree.
Word order: Subject + 稍微 + verb / adjective + 一点儿 / 一下.
稍微 almost always needs a small-amount word after the verb, such as 一点儿, 一些, or 一下.
Without that closing 一点儿 or 一下, a 稍微 sentence sounds unfinished.
