presumptuous狂妄無禮

把師道尊嚴用一句假設說盡，逗趣又帶刺。

If you knew, you'd be ...

回敬別人自以為是、或開玩笑壓對方一頭時用；正式場合別用。

If you knew that, you'd be the one teaching me. ／ Then you'd be telling me, not the other way round.

口語

重讀 knew 和 teaching，兩個 teaching 之間稍停。

If you knew the answer, you'd be the one explaining it to me. 你要是知道答案，就該是你講給我聽。

用一本正經的官腔壓學生，presumptuous 一詞把威嚴拉滿。

It is presumptuous (and rude) to do ...

諷刺地指出對方越界、放肆時可用；平時對長輩別這樣講。

It is rude to speak over your teacher. ／ It is presumptuous to assume you know better.

正式

presumptuous 重音在 -sump-，句末 Is that clear? 上揚。

It is presumptuous to answer for someone else. 替別人做回答，是很放肆的。

先給足危險感，再用三個詞收尾，像警報一樣短促有力。

It's ... stuff. Blows you up.

誇張地形容某物很危險時可用；對陌生人別拿爆炸開玩笑。

This stuff is dangerous and can blow you up. ／ Mix it wrong and it goes up.

口語

horrible, dangerous 連讀，Blows you up 重讀 blows。

一句就把複雜工序的核心點破，the trick is 是教科書式的實用句。

The trick is to ...

教別人做事的竅門、或點出關鍵步驟時用；閒聊抱怨時別套。

The secret is to add them evenly. ／ The key is to keep the amounts equal.

中性

trick is to 連讀，pour them in in equal 裡兩個 in 要分開。

用一句反問加期待，把祖父的偏心與信心都講出來了。

口語

counting on 連讀，all five 重讀收尾。

兩句結構簡單，卻把規則和懸念一次說清，像遊戲開場白。

中性

finds them wins 三處 s 連讀，prize 句尾放平。
