简要说明幼儿坚持性及其发展的关键年龄。
正确答案及解析
正确答案
解析
(1)3岁时幼儿坚持性的发展水平很低，在某些条件下能够开始有意识地控制自己的行动，但是行动过程不完全受行动目的制约，坚持时间极短。在实现目标过程中，困难枯燥会使他们失去坚持完成任务的愿望和行动；许多情况下根本不能接受坚持性任务。
(2)坚持性发生明显质变的年龄在4～5岁，是幼儿坚持性发展变化最迅速的年龄，也是受外界影响波动最大的年龄。实验表明：4～5岁是幼儿坚持性发展最关键的年龄。正是在这个年龄，外界环境对幼儿坚持性的影响最大。

For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back.

For the Luddite (反对技术进步的人)
