“What ! You too?I thought I was the only one.”Have you ever said this to someone? If so, you may have ended up becoming friends with this person.

It seemed that similarity often helps form friendships. The Greek philosopher(哲學家) Aristotle once said, “Some define(下定義) friendship as a matter of similarity. They say that we love those who are like ourselves.”

Now , there is some science behind this idea. Scientists from University of California said friends have similar brains, Scientific American reported.

The scientists invited 42 university students to take part in an experiment. Each student watched the same set of videos, which included a comedy, a discussion and a soccer match. Meanwhile, scientists studied their brains and recorded their brain activity.

According to their study, friends who watched the same video clips reacted in similar ways. Similar parts of their brains lit up while watching the videos, especially parts that were connected with motivation(動力)， learning and memory.

However, people who weren’t friends had different reactions to the same clips.

“Having close friends whose brains react like ours may be rewarding because it makes one’s won values, opinions, and interests strength,”scientist Carolyn Parkinson told Business Insider.

But brain similarity is not the only thing that can result in friendship. Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone.

They did an experiment with first-year college students who met in class for the first time. In this experiment, students who sat in neighbouring seats were more likely to become friends.

A. They had watched the same video clips.

B. Friends had similar reactions to the same clips.

C. Watching videos improves one’s memory.

D. It’s good to have friends who react similarly.

4.According to the story , what else may help build friendship?

Once upon a time, there was a family with 18 children living in a village. Two of the children, both boys, loved painting very much, but the family was so poor that it was impossible to send both of them to study at art school at the same time.

After many discussions, the two boys finally worked out a plan. They would toss(拋) a coin. The loser would go down into the mines(煤礦)and,with his money, pay for his brother's college tuition(學費).Then, when the brother who won the toss finished his studies, he would pay Tor the other brother to study at the college.

One of the brothers, Albrecht Durer, won the toss and his brother Jack went down into the mines. Durer worked with all his heart and his paintings were much better than those of most of his teachers. He was beginning to make a lot of money for his paintings.

Durer returned. When he told Jack he could go to art college, Jack said softly: "The fouryears in the mines have done too much to my hands. It is too late. Now I can’t even hold a glass."

To show his great love and respect for his brother, Durer drew his brother's hands with palms(手掌）together and thin fingers towards the sky. He called his drawing The Praying Hands, which became very famous years later.
