First, fold the mask from edge to edge. Then make a knot in each ear loop. Push the knot as close to the edge of the mask as possible.

•from edge to edge 從邊到邊
•make a knot (n.) 打個結
•ear loop 耳繩 ; 耳套圈

首先，將口罩長邊向內對折，然後在每個耳繩子上各打一個結，繩結盡可能打在靠近口罩的兩側邊緣。

Next, fold and tuck the extra material under the edges of the mask. Hold the mask up to your face and gently push the nose wire against your nose so it fits snugly. Place the ear loops around your ears as you normally would to secure the mask.

•tuck 把…藏入；把…塞進、塞入
•fit snugly 緊密貼合
•secure the mask 固定口罩

接下來，將兩側多餘的材料折疊並塞入口罩內側。將口罩貼近你的臉，輕輕地將鼻壓條壓到你的鼻子上，使其緊密貼合皮膚。像平時一樣將耳繩套在耳周以固定口罩。

Be sure to remove any gaps in the mask around your nose and cheeks for the best protection. And this is what we call knot and tuck.

•remove any gaps 排除任何間隙
•for the best protection 以獲得/達到最佳保護
•knot and tuck 打結與塞入
•knot (n.) （繩等的）結 ; (v.) 打個結

務必確保鼻子和臉頰周圍與口罩沒有任何縫隙，以達到最佳保護。這就是我們所說的打結和塞入。
