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。(满分２５分)                       

After my brother died in an accident , my mother was inconsolable(痛苦的，极其伤心的). I was only 4 years old at that time, but I still understood the seismic shift（地震的改变） in my mom’s attitude towards safety. Suddenly, everything around us was potentially dangerous.

I grew up with a lot of restrictions（限制）that were meant to protect me. I couldn’t walk home from school by myself even though everyone I knew already did. I couldn’t attend parties, or go to summer camp, because what if something happened to me. My life was divided into “things you should avoid” and “things you needed to do in order to have a good , long life”.

I became a natural worrier. I worried about things like getting cancert, losing my wallet, car accidents, and earthquakes-disasters big and small, real and imagined.

When I was 14, my mother died suddenly in a car accident. That loss, on top of my brother’s unnatural death, could have paralyzed(瘫痪) me. But at my mom’s funeral, I made a choice. I could either live out the rest of my life trying to be “safe”　or I could be brave enough to live out a fulfilling, exciting and, yes, sometimes dangerous life.

I began constantly forcing myself to do the things that frighten or worry me. In fact, I’ve developed a rule for myself: If it scares（使….害怕） me, I have to do it at least once. I’ve done lots of things that my mom would have worried about: I’ve ridden a motorcycle, I’ve dived, I’ve tried rock-climbing, I’ve traveled a lot.

Courage（勇气，勇敢） isn’t a natural attribute (性格) of human beings. I believe that we have to practice being courageous; using courage is like developing a muscle. The more often I do things that scare me, the more I realize that I can do a lot more than I originally thought I could. I’ve also come to believe that fear can be good thing if we face it.
