According to a new study, good friends are actually the next closest thing to family in genes(基因).
U. S. researchers have found that we are more genetically similar to our friends than to any stranger. The study suggested that genes may influence how we choose our friends.
The study looked at the gene information of nearly 2,000 people, who were chosen from a small U.S. town as part of a larger heart study. The study showed that friends share about 0.1 percent more DNA than strangers do.
Besides providing DNA information, participants(参与者)in the study were also asked who their closest friends were. Because all of the participants came from such a small community, it made this group suitable for such studies. It has also led to argument. Friendships in small communities are more probably genetically connected, because such communities usually have fewer kinds of genes.
“I wonder whether the ways used in the study can fully explain the known causes which drive friendships,” said Oxford’s Dr. Rory Bowden.
There was one interesting finding from the study. Some of the genes that friends are most likely to have in common are about smell. “You may really love the smell of coffee. And you’re drawn to a place where other people have been drawn because they love the smell of coffee too,” Fowler explained. “And so that might be the possible place for you to make friends.”

When I was 13 years old, a girl gave me an important gift. It was a smile. It was the early autumn of my first year at a junior high school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone. Every time I heard the other students talking and laughing, I felt even more lonely. I couldn’t talk to anyone about my problem, and I didn’t want my parents to worry about me. Then one day, my classmates were talking with their friends, but I sat in silence. At that moment, a girl entered the classroom. I didn’t know who she was, she passed me and then turned back. She looked at me and, without a word, smiled. Suddenly, I felt the touch of something bright and friendly. It made me feel happy, lively and warm. It was like a hidden treasure.
That smile changed my life. I started to talk with the other students and made friends. Day by day, I learnt to trust people, and they included me in their circle of friends. The girl with the bright smile has become my best friend now, and we stick together like glue. One day, I asked her why she smiled at me, she said she could not remember!
Now I believe that the world is what you think it is. If you think you are lonely, you might always be alone. So smile at the world and it will smile back.
