阅读理解。从ABCD中选出正确的答案。（每题2分，共40分）

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, 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. Trevor used it to get to work, putting in 60-hour a week to support his young family. And the bike was also used to get groceries（食品杂货）, 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.

People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性） as a whole. And it has influenced（影响） us to be more mindful（注意的，留神的）of ways we, too, 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.
