I am afraid we can't pay off at one time, we have to pay by installment.

恐怕我们无法一次将款项付清，只能分期付款。

I'd thought we'd agreed I'd settle the bill by installments. I could pay half now, but I'm not prepared to.

我以为我们都同意了按分期付款。我现在可以付一半的金额，但是我不打算付。

At such times stories were told by installments, things of a satisfying nature were either produced and eaten or hastily tucked into pockets to be disposed of at night, when Becky went upstairs to her attic to bed.

在这种时候，故事是分期讲述的，令人满意的东西要么被制作出来吃掉，要么被匆匆塞进口袋里，等到晚上贝基上楼去她的阁楼睡觉时扔掉。
