Her mother had begun to sing halfway up the stairs.

她的母亲已经在楼梯的中间开始唱歌了。

Sing up, boys, I can’t hear you!

【sing】再唱得响点，伙计们。 我听不见！

The wind sang up in the oak trees on the block and banged the blinds against the side of the house.

风在街区的橡树中呼啸而过， 把百叶窗撞在房子的一侧。

There were still a few hours to go before the beginning of the new year, so we all sat around the dining room table and sang up until a few minutes before midnight.

离新年还有几个小时，大家围坐在饭桌边唱到午夜前几分钟。
