英語六級-攻克閱讀關鍵句123. It's no secret that there's a lot to put

123. It's no secret that there's a lot to put up with when waiting tables, and fortunately, much of it can be easily forgotten when you pocket the tips.

譯文　

眾所周知，等客人點菜的時候，服務員通常都需要百般忍耐，不過當他們把小費放入口袋的時候，就把這些麻煩忘光了。

點睛　

本句的結構是“It＋be＋名詞（no secret）＋that從句”，其中it是形式主語，that引導的主語從句是本句真正的主語。
it is no secret意為“眾所周知”。如：
It is no secret that Singapore owes it all to its uncorrupt leaders for where it is today. 眾所周知，新加坡今天的成績得歸功于其廉潔的領導人。
短語put up with的意思是“忍受，承受”。如：
I could hardly put up with that guy any longer. 我再也不能忍受那家伙了。
pocket作動詞講時，意思是“將……放入口袋”。tip的意思是“小費”。
