把复杂问题归咎于单一因素,未免显得过于幼稚。Bǎ fùzá wèntí guījiù yú dānyī yīnsù, wèimiǎn xiǎnde guòyú yòuzhì.Blaming a complex problem on a single factor seems rather immature.
都三十岁了,还这么幼稚!Dōu sānshí suì le, hái zhème yòuzhì!You are already thirty and still so childish!
别再幼稚了,我们需要认真谈一谈。Bié zài yòuzhì le, wǒmen xūyào rènzhēn tán yī tán.Stop being childish, we need to have a serious talk.
