家长们对学前教育期望值过高，导致了托儿所费用的水涨船高。很多父母均认同这样一种看法：如今每个家庭都是一个孩子，于是一些托儿所利用家长“望子成龙”(“望女成凤”)的心态，“投其所好”，想方设法推出各种名目的学前教育计划和培养目标，无形中，也大大增加了家长的投入。
参考答案:
Parents' overestimate to the preshcool education leads to the rising charges of nursery schools accordingly.Many parents believe the fact that each family has only one child,parents simply hope their son or daughter become somebody in the future,therefore,some nursery schools cater to these parents' thought and introduce various kinds of perschool plans and fostering objectives which add virtually to the parents' financial burden.
家长们对学前教育期望值过高，导致了托儿所费用的水涨船高。
分析:
如果把“家长们对学前教育期望值过高”翻译成一个句子，那就会造成句子比较松散，因此这里处理成名词结构，作主语: Parents' overestimate to the preshcool education.同时注意“水涨船高”的意思是“相应的增长”，因此译成: rising charges of nursery schools accordingly。
