用a piece of cake表达“易如反掌”

如果说做一件事就像 a piece of cake, 意思就是易如反掌，小菜一碟。

• Changing the wheel on the car was a piece of cake – I was happy to help!
• I don‘t know what all the fuss was about – the exam was a piece of cake! I had half an hour to spare.

值得注意的是，所谓蛋糕上的冰糖 the icing on the cake 意思就是锦上添花。

• It was great to win the match but the icing on the cake was getting promoted to the Premiership!
