a guessing game瞎猜

把整门学问压成一句贬语，气场十足，也埋下后面自打脸的伏笔。

Without them, X is nothing more than Y.

强调某物不可或缺时用；对同事讲道理可以，饭桌上说显得说教。

Without data, it is just a guessing game. ／ Take that away and all you have is guesswork.

正式

nothing more than 连读，guessing game 两词都重读。

Without numbers, this plan is nothing more than a guessing game. 没有数据，这个计划不过是一场瞎猜。

祈使句接结果句，像格言一样干净，把推理一步说透。

Find X, and you have found Y.

把复杂步骤压成一句结论时用；对下属布置思路合适，闲聊别用。

Find the motive, and you find the man. ／ Locate the accomplice and the case is closed.

中性

Find that somebody 一顿，and 后 you have found 连读加快。

Find the bad cable, and you have found the fault. 找到坏掉的那根线，你就找到了故障点。

用 shall 和 before the day is out 立下军令状，老派又自信。

I shall ... before the day is out.

郑重承诺限时完成时用；对上司或客户合适，朋友间说会显得做作。

I'll have it done by the end of the day. ／ It will be settled before nightfall.

正式

shall 轻读，before the day is out 一口气连下来。

I shall send the draft before the day is out. 今天之内我会把草稿发出去。

开场先摆出一副要教人的架势，用的是命令句加将来时，自信得不容置疑。这种「先镇住场面再讲道理」的句式，很值得搬进自己的表达里。

You listen to me and you will ...

要训话、想让人认真听时用，语气强势；对平级或朋友说容易显得居高临下。

Pay attention and you might pick something up. ／ Hear me out and you will learn a thing or two.

中性

listen to me 连读，will learn 重读，something 轻收。

You listen to me and you will learn something useful. 你听我说，能学到点有用的东西。
