系扣子 系拉锁 系鞋带 系皮带……英文里有统一的动词吗？
作者：小雅和英美友人
本文美国朋友语音示范本文美国朋友语音示范03:25来自你和宝宝说英语系扣子、系拉锁、系鞋带、系皮带……英文里有统一的动词吗？答案是：有，一个是伟大的万能动词do，另一个是fasten，但是它们还是不如中文的“系”通用性强，还要具体情况具体分析，尤其慎用fasten。
写这篇文章是一个漫长而痛苦的过程，因为我们希望把各种情况、各种表达方式都总结全，让大家可以收藏查阅。外教们也快被小雅逼疯了，无奈地说：This topic has been tricky!
为了让同学们一目了然，小雅做了一个表格：
Do/undo和fasten/unfasten适用情况表
Clothing only指后面只能加衣物、鞋和配饰；Fastener only指后面只能加用于系紧的装置；Both指两者都可以加。还有几点总结希望能帮到大家：(1) “系扣子”不说button your buttons，但是“系带子”可以说tie your tie，原因是前者音节过多，太wordy。(2) 在英式英语里，可以直接说：Button up! Zip up! 在美式英语里，需要有it，说Button it up! Zip it up!
Fastening 系
1. Button 系扣子
系扣子、系（有扣子的）衬衫：
(1) Button up your shirt. = Button your shirt.
(2) Do your buttons.
解扣子、解（有扣子的）衬衫：
(3) Unbutton your shirt.
Button up的反义词不是button down。
(4) Undo your buttons.
(5) Undo your shirt.
综合(2)(3)(5)可以看出，undo后面既可以加扣子，也可以加衬衫，但是do后面只能加扣子。
2. Zip 系拉锁
系拉锁、系（有拉锁的）外套：
(1) Zip up your jacket. = Zip your jacket.
(2) Do your zipper.
(3) Fasten your jacket.
解拉锁、解（有拉锁的）外套：
(4) Unzip your jacket.
(5) Undo your zipper.
(6) Undo your jacket.
(7) Unfasten your jacket.
3. Snap 系按扣
系按扣、系（有按扣的）大衣：
(1) Snap up your coat. = Snap your coat.
(2) Do your snaps.
(3) Fasten your snaps.
(4) Fasten your coat.
解按扣、解（有按扣的）大衣：
(5) Unsnap your coat.
(6) Undo your snaps.
(7) Undo your coat.
(8) Unfasten your snaps.
(9) Unfasten your coat.
因为按扣是扣子的一种，所以也可以用button your coat。
4. Buckle 系带扣
Buckle这个词，当宝妈宝爸的肯定不陌生，因为有一首One, Two, Buckle My Shoe。但是，不是系所有鞋都用buckle，它只适用于这种有带扣的鞋：
系下面这三种腰带-belt，都用buckle。
系带扣、系腰带：
(1) Buckle your belt.
(2) Do your buckle.
(3) Fasten your buckle.
(4) Fasten your belt.
解带扣、解腰带：
(5) Unbuckle your belt.
(6) Undo your buckle.
(7) Undo your belt.
(8) Unfasten your buckle.
(9) Unfasten your belt.
5. Hook 钩
把钩钩上、把皮带钩上：
(1) Hook your belt.
(2) Do your hook.
(3) Fasten your belt.
把钩解开、把皮带解开：
(4) Unhook your belt.
(5) Undo your hook.
(6) Unfasten your belt.
6. Clasp 系龙虾扣

(1) Clasp your necklace.
(2) Do your clasp.
(3) Fasten your necklace.
(4) Fasten the clasp.
(5) Close your clasp.

7. Tie 通过打结的方式系
系鞋带、系鞋：

(7) Untie your shoes.
(8) Undo your shoelaces.
(9) Undo your shoes.
(10) Unfasten your shoelaces.
(11) Unfasten your shoes.
8. Strap 用带子系
以系鞋子上的粘扣-Velcro strap为例。在英语里，粘扣被认为是strap-带子，这点不太好理解，因为带子通常是比较长的。另外，Velcro原本是一个尼龙搭扣的品牌“维可牢”，后来人们就用Velcro strap指代所有的粘扣了。
系粘扣、系鞋：
(1) Strap up your shoes. = Strap your shoes.
(2) Do your straps.
(3) Fasten your straps.
(4) Fasten your shoes.
解粘扣、解开鞋：
(5) Unstrap your shoes.
(6) Undo your shoes.
(7) Undo your straps.
(8) Unfasten your straps.
(9) Unfasten your shoes.
这组句式也适用于其他类型的strap，比如：把背带裤背带系上用strap up your overalls.
