“盖被”常见的英文表达是 “cover oneself with a quilt” 或者更简洁地说 “use a quilt”（在语境中能表明是用于盖的时候），也可说 “pull the quilt over oneself” 。
例如：
It's cold tonight. You should cover yourself with a quilt.（今晚很冷，你应该盖上被子。）
I always use a quilt when I sleep.（我睡觉时总是盖被子。 ）
She pulled the quilt over herself and went to sleep.（她盖上被子，睡着了。 ）
