比如當我們在國外一家店里遭到了歧視，最佳辦法是去找他們的經理：
客人A: Hey, are you the manager? I have a complaint about one of your employees.
嘿，你是經理嗎？我要投訴你們這里的一位員工。
經理B: Yes, I'm the manager. Please tell me what happened.
是的，我就是經理。請告訴我發生了什么。
I have a complaint about…
我要投訴…；我對…有意見
這里complaint是complain的名詞形式，而complain是動詞。
投訴對象可以是個人，也可以是物，或者事。
舉個例子：
① The food was good, but I have a compalint about the service. It's too slow.
食物很不錯，但是我要投訴一下服務。太慢了。
② I have a complaint about the opening paragraph. I think it's too long and boring.
我對開頭一段有意見。我覺得太長太無聊了。
經理詢問要投訴誰，客人指出了那個種族歧視的人：
客人A: See that guy over there? He made a racist comment about me. It was very offensive.
看到那邊那個人了嗎？他對我說了種族歧視的話。非常冒犯人。
經理B: Racist? How so? We take racism here very seriously.
種族歧視？怎么回事？我們這里對種族歧視是非常嚴肅對待的。

當有人說了關于“種族歧視”的言論，就可以用這個句式表達出來：
Make a racist comment about
對…發表種族歧視的言論
· Make a comment = 發表言論
· Make a racist comment about + 人 = 發表了針對“某人”的種族歧視言論
舉兩個例子：
① Everyone's mad because the CEO made a racist comment about African Americans.
所有人都很生氣，因為CEO對非裔美國人發表了種族主義言論。
② My coworker makes racist comments about Asians all the time and HR does nothing about it.
我的同事總是對亞洲人發表種族歧視的言論，而人力資源部門卻什么也沒做。
說明對方說了“種族歧視”的話，還是再加一句，說明一下：
It was very offensive.
這非常無禮/非常冒犯人
在口語中的舉例：
① The ad made fun of Chinese people. It was very offensive.
這則廣告嘲笑中國人。非常冒犯人。
② I saw the movie and it was very offensive. Theyportrayed Americans as very dumb.
我看了這部電影，非常冒犯人。他們把美國人描繪成非常愚蠢的人。
