「cut」比看起來更鋒利：Off、Out、Down、Back

動詞 cut 聽起來很單純：一把刀、一把剪刀、一條俐落的切線。但英文對它的使用遠遠超出紙張和麵包。暴風雨可以 cut off 電力。醫生可能叫你 cut down on 糖。公司可以 cut back 開支。沒禮貌的駕駛會 cut in。一段清楚的說明能 cut through 混亂。

那個實體畫面始終都在：某樣東西被分開、減少、打斷或縮短。一旦你感覺到那個俐落的小動作，這些片語就好懂得多。

快速解答

cut 的核心概念是「用力道或精準度去分開或減少」。介副詞告訴你發生的是哪一種分離或縮減。

• cut off：切斷、停止供應、打斷或孤立
• cut out：移除、戒掉，或突然停止運作
• cut down：減少、砍倒或貶損
• cut back：縮減開支、活動或數量
• cut in：插話或插隊、切入車道
• cut through：直接穿過，或讓混亂變清楚

這個家族很鋒利，但不一定負面。你可以聰明地 cut back 開銷、cut out 一個壞習慣，並 cut through 一團混亂的說明。

核心概念

想到 cut，就想像一條線被切斷。這條線可能是實體的，像一條繩子；可能是社交的，像一段對話；可能是實務的，像一份預算；也可能是心智的，像一團混亂。

Off 完全切離。Out 從中間取走一塊。Down 縮小尺寸或數量。Back 從原有水準往回減。In 突然切進別人的空間。Through 在屏障上開出一條路。

這些片語通常聽起來很果斷。cut 某樣東西不是輕輕微調，而是做出明確的改變。

Cut Off：切斷、打斷、停止供應

Cut off 是 cut 家族中最常用、最靈活的片語之一。

• The village was cut off by heavy snow.
• The phone call got cut off in the tunnel.
• The company cut off access to the old system.
• Sorry to cut you off, but we are almost out of time.
• The driver cut me off on the highway.

主要概念是分離。村莊與外界分隔，電話斷線，存取被停止，發言被打斷，駕駛突然切到你前面擋住去路。

有受詞時是可分的：

• They cut off the water.
• They cut the water off.
• They cut it off.

但在被動句裡，它常以類似形容詞的姿態出現：

• We were completely cut off from the outside world.

Cut Out：移除或停止

Cut out 可以表示取下一塊、戒掉某件事，或停止運作。

• She cut out a picture from the magazine.
• The editor cut out three paragraphs.
• My doctor told me to cut out fried food.
• The engine cut out halfway up the hill.
• Stop shouting, or I will cut out the game for today.

字面畫面很容易懂：從整體中取下一塊。延伸出去，就成了從生活中移除一個習慣、從文章中刪掉一段文字，或引擎突然失去動力。

當有人移除某物時，通常是可分的：

• The editor cut out the joke.
• The editor cut the joke out.
• The editor cut it out.

"Cut it out!" 也是固定的命令句，意思是「住手！別鬧了！」

Cut Down 與 Cut Down On

Cut down 有兩個主要方向：把某物砍倒，或減少某物。

• They cut down the old tree after the storm.
• The new process cut down waiting time.
• This app helps me cut down on distractions.
• I am trying to cut down on coffee.

要減少一個習慣或反覆出現的活動時，用 cut down on：

• cut down on sugar
• cut down on screen time
• cut down on unnecessary meetings

不加 on 時，受詞通常是被直接減少的東西：

• The change cut down costs.
• The route cuts down travel time.

另外還有一個非正式的意思：嚴厲地貶損某人。

• He cut her down in front of the whole team.

這個意思尖銳又針對個人，使用時要小心。

Cut Back：從現有水準往回減

Cut back 表示縮減數量、預算、活動或習慣。

• We need to cut back on expenses this month.
• The city cut back bus service after midnight.
• She's cutting back on social media.
• The company cut back hiring during the slow season.

Cut back 和 cut down on 有重疊，兩者都可以表示減少。Cut back 通常聽起來是因為受限而從現有水準往回減：金錢、時間、精力、人力。Cut down on 通常聽起來是為了變好而減少某個習慣。

比較：

• "I'm cutting down on soda." = 我想喝少一點。
• "The office is cutting back travel." = 預算或政策正在被縮減。

Cut In：插話或突然切入

Cut in 表示突然進入一段對話、一條隊伍、一支舞或一條車道。

• She cut in before I finished my sentence.
• A motorcycle cut in front of the bus.
• We were waiting politely, but one man cut in line.
• May I cut in? I have one quick point.

語氣很重要。Cut in 常顯得無禮，但在會議中，如果你真的需要插話，"May I cut in?" 可以是有禮貌的。

不要和 cut into 搞混，後者常表示實際切進某物，或侵蝕金錢與時間：

• The knife cut into the cake.
• The repair bill cut into our savings.

Cut Through：開出一條路，或讓事情變清楚

Cut through 可以是字面的，也可以是比喻的。

• We cut through the park to save time.
• The road cuts through the mountains.
• Her explanation cut through the confusion.
• The whistle cut through the noise.

畫面是一條銳利的路徑穿過屏障。在溝通上，cut through 表示讓某件事突然變得清楚或醒目。

常見錯誤

• "I need to cut coffee." → "I need to cut down on coffee" 或 "cut back on coffee." · 減少習慣要加 on。
• "The call cut." → "The call cut out" 或 "got cut off." · 用介副詞點出是哪一種中斷。
• "He cut me in while I was speaking." → "He cut me off" 或 "He cut in while I was speaking." · Cut someone off 接受詞；cut in 通常不接。
• "We cut out expenses." → 如果是完全砍掉，可以這樣說。如果只是減少，要說 "We cut back on expenses."
• "She cut down him in the meeting." → "She cut him down in the meeting." · 代名詞要放中間。

小練習

1. The storm _____ _____ electricity to several towns.
2. I am trying to _____ _____ _____ late-night snacks.
3. The editor _____ three pages _____ of the report.
4. A taxi _____ _____ front of our bus.
5. Her simple chart _____ _____ all the confusion.

解答

1. cut off — 停止供應用 cut off。
2. cut down on — 減少習慣用 cut down on。
3. cut / out — 刪除文字用 cut out。
4. cut in — 突然切進車流空間是 cut in。
5. cut through — 讓混亂變清楚是 cut through。

小結

遇到 cut，找出被分開或被減少的東西。一條連線、一個習慣、一份預算、一句話、一條車道、一團混亂：每一樣都可以朝不同方向被切開。
