my cup of tea “我的那杯茶”？？？？

         老外常說(shuō)：It's not my cup of tea. It's my cup of tea. 究竟何意？“不是我的那杯茶”？“是我的茶”？NO! NO! NO! 其實(shí)，這兩句話意思是：“不是我的菜”?！笆俏业牟恕薄?/span>
        1. That's my cup of tea. I must go for it. 
             那是我的菜。我得去爭(zhēng)取。
        2. Sorry. I'm not going to the concert with you. It's not my cup of tea. 
             抱歉我不能陪你去看演唱會(huì)。我對(duì)演唱會(huì)不感興趣。
