第二节 读写任务(共1小题,满分25分)

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

My wife, daughter, and I moved into our home nine years ago. We called the area in front of our house “rock graden” as it is full of rocks.

Last summer I found a tiny little plant which I could not immediately identify at the end of the rock garden. I knew I didn’t plant it and my wife claimed that she didn’t either. We decided to let it continue growing until we could figure out what it was.

Weeks passed and as I made my way back to the mystery plant, it appeared to be a sunflower. It was spindly with a tall skinny stalk and only one head on it. I decided to take care of it and weed around it. As I pulled rocks from the area to get to the weeds, I notived something unusual. The sunflower had not started where I saw the stalk begin. It actually had begun under a big rock and grown under and around it to reach the sun.
