　　"I start by rinsing my mouth," Lucy says. That is, when she first walks in to her bathroom she begins to clean up by rinsing her mouth out, or "rinsing her mouth."   露西说，“我开始漱口”。也就是她走进卫生间就开始洗漱，首先清理口腔，或者叫“漱口”。

　　So, she takes some liquid mouthwash, "mouthwash," (one word) which is a kind of liquid soap for your teeth. 她用的是液体漱口水。漱口水（mouthwash）是牙齿的液体肥皂。

　　It helps clean your teeth and make your breath smell better, or at least it's supposed to. 理论上来说，它可以帮助清洁牙齿，清新口气。
