3月18日晴自然课上,和蔼的陈炳南老师给我们布置了一个重要的任务,回家做一个关于热胀冷缩的小实验,同学们听后高兴得手舞足蹈。回家后,我赶忙放下书包,性急地拿出《自然》书翻阅起来,啊,找到了:瘪了的乒乓球经过开水的浸泡后会恢复原形。我从存钱盒里重掏出一元硬币,直奔商店,一眼看到了一小筐像鸡蛋一样的乒乓球。我轻轻地抓起两个,快速地将钱递到店主的手里,连奔带跑地回了家。
On March 18, in the nature class, the friendly Chen Bingnan teacher arranged an important task for us to go home and do a little experiment on thermal expansion and contraction. After classmates listened, they were happy to dance with each other. After I got home, I hurried off my schoolbag, hurriedly pulled out the book of nature, and found it: the flattened ping pong returned to its original shape after soaking in boiling water. I dug out a dollar coin from my savings box and went straight to the store to see a small basket of eggs like an egg. I gently grabbed two, quickly handed the money to the hands of the owner, ran back to home running around.
