Answer 1

今天妈妈买回一瓶橙子汁，我从中发现了一个科学道理。

那天妈妈在与客人谈话，叫我把橙子水拿去喝。那时我正在看电视，突然我的同学打电话告诉我昨天的作业，我误把棉签当作钢笔，橙子水当作墨水，就把棉签往橙子水里一沾写下了昨天的作业，我挂了电话，再来看我写下的作业，天啊！竟然连一道水迹也没有！怎么办呢？我把纸拿在手里左摆右弄，最后把纸往灯下一照，字又现出来了，真奇怪！

我又照刚才的方法做了一遍，然后再往灯下一照，字也现出来了。怎么会这样呢？我找到《十万个为什么》，便打开目录查找，不多会儿，“呀，找到了。”

原来橙子水本身是水做的，写在纸上马上就被纸吸收了，自然灯下一照，强光就把印迹显现了出来。

我想，只要用心，生活中处处有科学，事事学科学

Answer 2

I have rested for a week. I began to feel bored. So I went out with my friends. They are my best friends in the middle school. We didn’t go to someplace special. We just saw the other. We had lunch together. While we were having lunch, we were still talking about the new school and new friends. Yes! A year later, we have grown riper. And we learned much more things and got new life. We haven’t enough time to play, to waste and to lose the way. We only have two years. Two years to go, we will get the real life which belongs to us.
