写作思路：可以将爸爸妈妈上学时候的学校写成过去的学校，将自己现在读书的学校和爸爸妈妈那时候的学校进行对比式的描述。
正文：
Over the past 30 years of reform and opening up, earth shaking changes have taken place in all fields of our country. No matter in material, or in spirit. I'll start from school.
改革开放三十年来，我们国家再各个领域发生了翻天覆地的变化。无论在物质上，还是在精神上。我就从学校写起吧。
When mom and Dad were in the first grade of primary school, the spring breeze of reform just blew all over the motherland. At that time, the school was just a few simple classrooms; The course is also a few ordinary courses, such as Chinese, mathematics, nature, physical education and so on.
爸爸妈妈上小学一年级时，改革的春风刚刚吹遍了祖国大地。那时的学校，不过是几间简单的教室罢了；课程也是几门普通课程，像语文、数学、自然、体育等。
A blank loess field, planted with a few trees and a piece of grass, is the playground; A few boards are nailed together, and a little black paint is the blackboard; A few sharpened pencils and an eraser, plus a few books, are all their learning aids.
一片空白的黄土地，种上几棵树和一片草，就是操场；几块木板钉在一起，涂点黑漆就是黑板；几枝削好的铅笔和一块橡皮，再加上几本本子，就是他们所有的学习用具。
Now our school, compared with the previous, can be said to be a different. Neat and beautiful teaching building; There are many courses added, such as art, morality, English and other interesting courses; A large green grass, red plastic runway, football field, basketball court. All kinds of fitness equipment, this is our place of entertainment.
而现在我们的学校，跟以前的比起来，可以说是天壤之别。整齐漂亮的教学楼；课程加了许多，像美术、品德、英语等趣味课程；一大片绿油油的草地，红色的塑胶跑道，足球场、篮球场。各种健身器材，这就是我们活动娱乐的场所。
All kinds of pens, pencils, cartoon stationery boxes, put into the "blue cat" schoolbag, this is our school's "weapon equipment"; The opening of computer courses and multimedia teaching are the concrete embodiment of the achievements of high-tech development in our school.
各种各样的钢笔、铅笔，卡通文具盒，装进“蓝猫“书包，这就是我们上学的“武器装备“；微机课的开设，多媒体教学等都是高科技发展成果在我们学校的具体体现。
With the development of science and technology in our country, our living standards are constantly improving: from thatched cottages to high-rise buildings, from bicycles to cars, from black and white to plasma liquid crystal color TV sets - all these are the personal feelings brought to us by the 30 years of reform and opening up.
随着我们国家科技水平的发展，我们的生活水平也在不断提高：从草房到高楼，从自行车到汽车，从小黑白到等离子液晶彩电——这都是改革开放三十年来带给我们每个人的切身感受。
Therefore, as primary school students in the new era, we should cherish this happy time, study hard and contribute our strength to the development of our motherland!
所以作为新时代的小学生，我们要珍惜这幸福美好的时光，努力学习，为祖国的发展贡献自己的力量！
我是一个中学生。我想告诉你我们学校变了好多。我们的学校比以前更大了。现在还有一个大花园。有许多树木和花草。我们可以坐在那里放松自己。
The playground is much bigger and more beautiful than before. Many boys play football there after school.And many girls play games there.They are very happy.
操场比以前更大、更漂亮了。许多男孩放学后在那里踢足球。许多女孩在那里玩游戏。他们都很开心。
Now we are in Grade 3, we have to study harder than before. Students do their homework in their free time.I think it is good, but taking some exercise is important, too.
现在我们是3年级了，我们要比以前更加努力学习。学生在他们空余时间做功课。我觉得这是好的，但锻炼也是很重要的。
Now our school is more beautiful, we are more polite to our teachers and we like tostudy very much. I think our school has changed in many ways.
现在我们的学校更美丽，我们对老师也更有礼貌，我们都非常喜欢学习。我认为我们的学校也在很多方面都改变了。本回答被网友采纳
