Social Bond of Animals

Friendship is an important part of human life. Friends can share our joys and our hardships. We aren’t alone. Many different animals also make friends.

Recently , a British research team finished an eight-year study of Indo-Pacific dolphins off the coast of Western Australia. These dolphins can use different tools to search for food. The researchers found that these dolphins are more willing to hang out with partners that like the same tool. Other factors, like family closeness or sex, have no influence on this relationship.

“It suggests that dolphins form social bonds (纽带)based on shared interests,w UK biologist Simon Allen told Science Daily. "Using different tools is time-consuming (耗时间的)” for dolphins to cooperate.

Apart from dolphins, elephants, horses and bats are also known to form friendships. Are friendships only limited to the same species? Of course not, The

Atlantic reported in 2015, a goat Timur was originally left in the tiger Amur's enclosure (围场)as a meal. But instead of eating Timur, Amur likes to play with it and gets jealous when others are close to his friend.

The Atlantic said it’s not unusual among captive (圈禁的)animals. That's because in captivity, animals don’t need to spend much time and energy marking their territory (领地)or looking for mates the way they would in the wild. They are actually more likely to feel bored. " In this particular situation, the animal's motivation to engage (参与)socially and playfully may be higher than eating. n

More interestingly, animals not only make friends but also try to keep lasting friendships. Take bats for example. In 2011, scientists found bats prefer to hang out with a few certain friends, keeping loose ties to the rest of their group.

Humans aren't so different. “We do not work, play and live together with the same friends all the time," Swiss zoologist Gerald Kerth explained. “ But nevertheless, we are able to maintain long-term relationships …despite our often highly dynamic (动态的)social lives."

People read books less often in these days. With the invention of radio, television and most recently, the Internet and computer games, it seems that reading books is no longer a popular activity. However, I believe that books are an important part of our lives.

Books offer an outstanding wealth of learning and at a cheaper price than taking a course. Books can make people cleverer, because heavy readers have greater knowledge of how things work and who or what people were.

Everything in today's society requires reading. Imagine trying to do something as simple as reading the directions on a medicine bottle without good reading skills. Someone could not understand them and become very sick or even die.

Even something as simple as walking or driving through the city could become very dangerous without enough reading. Sometimes, you must be able to understand what is written and explain the meaning of them; Some people say that reading is a waste of time and we can do better things with our time.

Even if we don't read books, we still read every day, and reading books can strengthen (加强) our abilities. Reading is one of the greatest things we can do in our spare time.

With a book, you can travel anywhere you want, do anything you want, and talk to anyone you want. Reading is very important in our lives, no matter how old you are. So I think people should read books.
