那不是有很多吗?自己编还是什么?如果自己编,我举个例子：
Today when I was waking up in the morning,I feel sunshine came in my house and it's a nice day today.I got down to first floor and watched my mice.The mother mouse gave birth to 6 baby mice.And today is their 6 day.But while I looked into the cage,I found that there were only 4 babies left!What had happened?I searched the Internet,and found many reasons to explain that event.The mother mouse had eaten her babies!If she was short of resouces or if she was frightened,she would eat her children!It was so dangerous!
