    我们生活在法制的国度,处处需有法,处处需遵法,而作为青少年,我们要应该让法律在心间长驻。我们所做的每一件事都是以“法律”作为开端的,没有了法律,我们的社会将会变得一片狼藉、不堪入目。  古云“法令行则国治,法令弛则国乱”。社会主义化的中国要长治久安必然要有法可依,更要有法必依,管理并保证国家各项工作都依法有序地进行,逐步实现社会主义民主的法律化、制度化。法制代表着权威与约束力。任何人都要被这权威影响,任何人都在法制的约束力下生活。然而,如果这个世界没有法制存在,又会是怎样一番情景呢?没有交通法的约束,马路上的车辆肆意行驶,车祸遍生;没有刑法的约束,大街上坏人恣意偷抢,争执满是;没有工商的约束,市场上厂家任意造假,纠纷到处……多混乱,多可怕,湛蓝的天空也都因此变得浑浊。由此可见法制之重要性。国家有法制,对于我们青少年也尤为重要。在安定和谐的环境里,我们能好好学习,幸福成长。

    二、 示范引导,引导孩子养成良好的学习习惯  学习是提高自身素养、增长才干的唯一途径。在日常的工作生活中,只有不断地学习、持续的学习,才能不断地增长知识、完善自我,促进自身的成长和发展,作为一个自然人是这样,但是为人父母还要担负起教育孩子、培养孩子的责任和义务,特别是作为青春期的中学生更应该多给予帮助和引导,避免出现偏差,而影响成长和学习。孩子是我们的未来和希望,孩子能否健康的成长和发展,事关社会的发展和时代的进步、事关民族的前途和命运。因此,作为父母必须首先做到率先垂范,在学习上给孩子当好向导或导游,坚决不能做帮手,引导孩子加强基础知识的学习,养成良好的学习习惯、认真思考的习惯。比如:孩子在做作业的时候遇到拦路虎,不要急着给他解题或是教给他怎样去做,而是应该给他讲关于该习题的原理、公式或带领着复习相关的内容,引导孩子自己去独立思考、独立完成,这样还能增强孩子的理解和记忆;其次是培养孩子的学习兴趣,引导孩子做到“学习快乐化、快乐学习化”
