a piece of cake简单

No shock there, considering how much work it is to raise a kid without a partner to lean on; yet to hear Sandra and Britney tell it, raising a kid on their “own” (read: with round-the-clock help) is a piece of cake.

考虑到在没有伴侣可依靠的情况下抚养孩子有多辛苦，这并不令人震惊；然而听桑德拉和布兰妮说起来，她们“独自”（意思是：有全天候的帮手）抚养孩子却是小菜一碟。
