on the sly偷偷地

用一句反问把自己的名字变成筹码，既狡猾又滴水不漏。

No need for mine. If I did, it mightn't be right, might it?

不想透露身份、又想堵住对方追问时用；对信任的人这样讲会显生分。

My name wouldn't help you anyway. ／ I could give you a name, but it might be false.

口语

mightn't be 连读，might it 句尾上扬。

No need for my name; it might not be the right one anyway. 不用问我的名字，反正说了也未必是真的。

用一条法律义务压过去，礼貌的问句里全是施压。

You realise that you're duty-bound to do X?

提醒对方有义务配合时用；对平级同事这样说会显得居高临下。

You know you are obliged to hand it over? ／ You understand that you have a duty to give it?

正式

duty-bound to 连读，any evidence 重读，句尾上扬。

You realise you're duty-bound to report it? 你明白你有义务上报吧？

一句说尽多年积怨和复仇的耐心，冷得没有一丝犹豫。

I waited my time to pay someone back.

说自己忍了很久终于要出手时用；对朋友这样讲会显得记仇太重。

I bided my time until I could get even. ／ I waited for the day I could settle the score.

口语

waited me time 快读，pay 'er back 重读，come now 收住。

We waited our time to pay them back, and it's come. 我们一直等着向他们讨回来，现在机会到了。

街头女人的委屈和恨意全在三个“她害的”里，重复句式一路逼出后面的报复。

It wasn't his fault. It was all hers, ...ing ... and ...ing ...

抱怨被人抢走什么、并把责任全推给第三者时用；正式场合或有孩子在旁边时不要照搬这种粗俗腔调。

It wasn't his doing; she turned him against me. ／ She took him from me, that's what happened.

口语

'is / 'ers 弱读吞音，gettin' / turnin' 尾音丢掉，三个分句递进。

It wasn't his fault. It was all hers, turning him against me. 不是他的错。全怪她，把他调转过来对付我。
