I used to have little passion(激情,热情)in my life. But what happened the other day changed my mind. It was then that I learned how        it is to have a passion in life.
That day I went home in Mom’s car. When Mom        at a red light, someone on the side of the road caught my eye. It was a man dressed        rags. He was homeless. That didn’t interest me, because I had seen         like him before. Those people usually looked unhappy and hopeless.
But this man was        in some way. He was not sitting down with a        expression. Instead, he had a         in his hand and was dancing happily to the music. The radio seemed to be the most precious thing he had.
“Mom, why does that man have a radio        he’s homeless?” I asked.
“He       it, “ she replied.
“But why doesn’t he use the money to buy food or clothes? He       something that he didn’t need.”
“Well, Sarah, sometimes food and clothes aren’t the most important.”
That man must care so much about        that he bought a radio instead of food or clothes. I soon realized that        is the key to life.
Since then I am always thinking of        is truly important in life. A home, a meal, clothes – these things are        part of the life. What we often forget is that we all need a joy, a light on a         day. We all need a passion which gives a person the happiness they need to keep going.
