一名中国留学生初到美国，在机场找卫生间，问老外：「Where is W.C.?」老外听不懂。一名中国太太到医院生产，洋护士问她：「Did you have a bowel movement?」她却听不懂。还有人学了几十年的英语，还不知道英语里的「大便」、「小便」、「放屁」真正如何说
至于性问题，更是老中难于启齿、欲语还羞的尴尬。见到洋大夫，窘迫万分，不知怎么样开口才是，真有「犹抱琵琶半遮面」的感受。
以下为一些「忌讳」的美语之整理。毕竟这类都是咱们平时生活的一部分，可能有一天这类「忌讳」之语还能「派上用场」呢!
卫生间
在美国一般都叫rest room或bath room或分别叫做 mens room 或 ladies room，不过在飞机上，则叫 lavatory，在军中又叫 latrine。至于 W.C.仍是过去英国人用的，在美国，几乎无人用。
解小便
最普通的说法是 to urinate，假如去看病，护士为了化验小便，就会给你一个杯子说：「Will you urinate in this cup?」大夫可能也会问：「Do you have trouble urinating?」=Do you have difficulty voiding?
除此之外，还有其他的说法：to piss = to take a piss = to take a leak = to void = to empty。 比如：
* I need to piss = I have to take a leak.
* How often do you get up at night to void?
除此之外，john是 bath room 或 toilet 的意思，这一般是指在户外工作场地所用的临时或流动性卫生间。不过也有老外把家的卫生间叫做 john。 比如：
* There are several johns in the construction site.
* He went to the john a few minutes ago.
* The manual labours have to use johns during their working hours.
不过，孩子多半用 to pee 。比如：
* The boy needs to pee.
然而，「小便检查」又叫做 urine test，由于这里的 urine 是化验的样品。 比如：
* Do I need a urine test?
注意：to piss off 是片语，又是指对生活气或对事物的不满。不过这是不礼貌的片语，少用为妙。 比如：
* He pissed me off. = He made me angry.
* He always pisses off the society.
假如「小便」有问题，也可以告诉大夫说：
* My urine is cloudy and it smells strong.
* I have pus in urine.
* I dribble a little urine after I have finished urinating.
* I am passing less urine than usual.
解大便
一般是用 to makea bowel movement 或 to take a shit。假如看病，大夫常问：「Do you have regular bowel movement?」
除此之外，还有其他的说法： to defecate =to discharge excrement=to take feces 。 比如：
* The patient needs to take a shit.
不过，孩子多半是用 to make a poo poo 或 to make a BM. 。 比如：
* The boy had a stinky BM.
但「大便检查」倒叫做 stool exam，由于 stool 也是一种化验的样品。 比如：
* The doctor has to exam his stool.
放屁
在美语里最常见的是 to expel gas 或 to fart 或 to make gas。 比如：
* 大夫有时问：「How often do you expelgas?」
* Is the gas expelled by belching?
* He said the more he ate, the more he farted.
* He has passed more gas than usual within the last two days.
* Be careful not to fart in the public.
至于消化不好的，大便不通或拉稀，也有不一样的说法。 比如：
* I have an upset stomach. = I have heartburn. = I have indigestion.
* Something has upset my stomach for two weeks.
* He hasconstipation. 或
* He has been unusually constipated.或
* He is having problem with irregularity.; 或
* He has no bowel movement for the past few days.
* He has bouts of diarrhea.=He is having trouble with diarrhea.
* He can see trace of blood and pus or mucus in his stool
