knock it off
“knock it off!”是美國人特別常用的一句話，相當于”Stop it”,謝謝帶有明顯的不耐煩情緒。舉幾個例子：
Angie: Sorry I’m late. My car broke down.(Angie:抱歉我以致了．我的車拋錨了。)
Betty: Knock it off! You always have excuses. (betty:少來這套！你總有借口。)
Michael: I’m certainly going to beat you. I will kick your sorry ass and make you beg for mercy. (Michael:我肯定會打敗你．我會狠狠教訓你，要你向我求饒。)
Daniel: Knock it off! You are just bluffing.(Daniel:得了吧．你只不過在虛張聲勢。)
Tessa: Are you dating Brad? (Tessa:你在跟Brad約會？)
Gina: None of your business. (Gina:不關你的事。)
Tessa: Come on, come on. Tell me. (Tessa:來嘛，來嘛．告訴我。)
Gina: No, Not a chance.( Gina:不行，沒門兒。)
Tessa: I’ll give you ten dollars if you tell me. (Tessa:你告訴我的話我就給你１０美元。)
Gina: Knock it off!!1 (Gina:拜托，別沒完沒了！)
除了knock it off，美國人也常說cut it out．兩者意思完全一致，都在一方叫另一方停止時使用。如果停止的對象是謊言或者廢話，cut it out 還可以用cut the crap來代替。比如：
Lisa: Where were you last night? I called you a hundred times . (Lisa: 你昨天晚上在在啊？我打了１００通電話找你。)
Damon: I was in a meeting with my boss and coworkers. Had to turn my cell phone off.（Damon:我在跟老板和同事們開會，不得不關掉手機。）
Lisa: Cut the crap! Your boss just called and asked why you missed last night’s meeting. (Lisa:別瞎編了！你老板剛打來電話，問供你為什么沒參加昨天晚上的會議。)
和cut the crap緊密相關的另個一短語是cut to the chase, 指直接進入正題．它是一個源于電影的短語，原指在動作片中將畫面切換到追逐戲(chase)的手法．由于追逐戲大多是動作片里最最好看的部分，cut to the chase就漸漸演變為get to the good part９直接跳到關鍵部分的意思。如果跟人談話時不想浪費時間聽謊言，廢話和客套的寒暄，就可以要求對方cut to the chase。比如：
Mike: You are the moist beautiful woman I’ve ever seen. You are extremely smart and talented. You are also… (mike:你是我見過的最美麗的女人。極其聰慧和能干。你……)
Tamara: Cut to the chase, will you? What do you want from me? (Tamara:開門見山，好嗎／你想要我做什么？)
需要注意的是，knock it off、cut the crap和cut to the chase口氣都比較沖，是不太禮貌的用語，跟長輩對話時應該盡量避免。
