A、To ride to work from home. B、To find a place to park his bike. C、To work for 10 hours. D、To warm up his cars. A短文开头说，“我的丈夫布鲁斯不

While most people were warming up their cars, Bruce, my husband, had to get up early to ride his bike five kilometers away from home to work. One day, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
    The bike, a black Kona 18 speed, was our only transport. Bruce used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries, saving us from having to walk long distances from where we live.
    I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
    This experience has had a spreading effect in our lives because it strengthened our faith in humanity as a whole. And it has influenced us to be more mindful of ways we can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.
