Stories sometimes describe snakes being cold-hearted characters. However, a team of scientists don't believe that. They say that one type of snake makes close friends.
The team of scientists did an experiment to see how garter snakes (带蛇) communicate with each other and to find out whether or not snakes make friends. The results turned out to be quite interesting.
The team gathered 40 garter snakes, and then put groups of ten garter snakes in an enclosure (围场). Inside the enclosure, there were four shelters (遮蔽物) for the snakes to go inside. The team then watched to see how the snakes behaved (表现)towards each other. They found the snakes were forming groups.
The experiment lasted eight days. Every day, the scientists took the snakes away from the enclosure. Then workers cleaned the space well. When the scientists put the snakes back in, they then went straight back to the same groups again! The scientists believed this could show the garter snakes make friends.
The team also said that they noticed two types of snake personalities (性格): shy and brave. Shy snakes were not ready to come out of the shelters inside the enclosure. But brave snakes were happy to do that.
Scientists of the team think we shouldn't be surprised that snakes form friendships. "All animals, even snakes, need to communicate with others." said Morgan Skinner, one of the scientists in the experiment.
It's not just snakes, though, that make friends. A recent scientific study found that dolphins do that, too.
a. The snakes went straight back to the same groups again.
b. The scientists wanted to find out if snakes make friends.
c. The scientists put groups of ten garter snakes in an enclosure.
d. The snakes were found forming groups in the enclosure.

In 2013, Chinese President Xi Jinping offered to build a Silk Road Economic Belt (经济带) and a 21st Century Maritime (海上) Silk Road, which became known as the Belt and Road Initiative (BRI, "一带一路"倡议). The BRI has brought cultures together for over ten years. As the BRI continues to bring the world together, young people from the Belt and Road countries can see how it continues to develop and have a deeper understanding of it. We did a survey of 125 Chinese students. The following survey is about BRI in the eyes of the students. The diagrams (图表) below show the results.
