A rucksack is a bag that you wear on your back.

帆是你肩上的。

Harry dragged his rucksack toward him and pulled out the fake Horcrux in which R.A.B.'s note was still folded.

哈利拉过他的帆，摸出那个假的魂器，R.A.B的字条仍然拆叠放在那。

She showered, took some clothes out of her rucksack and ran an iron over them in the hope that she looked a little more presentable.

她冲了个澡，从帆里拿出几件衣服熨烫， 希望自己看起来更体面一些。

Mrs. Weasley was still glowering as she kissed Mr. Weasley on the cheek, though not nearly as much as the twins, who had each hoisted their rucksacks onto their backs and walked out without a word to her.

韦斯莱夫人亲吻韦斯莱先生的面颊时，仍然板面孔。那对孪生兄弟的态度更坏。他们把帆甩到上，一句话没对妈妈说就走了出去。
