1 . “Do not tell anyone”. We often hear these words when someone tells us a secret. But keeping a secret is hard. We’re often tempted（引诱）to “spill the beans”, even if we regret it later.

According to the professor, Asim Shah, keeping a secret may well “become a burden”. This is because people often have an “eager and anxious urge（冲动）to share it with someone”. An earlier study, led by Anita, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted（托付）with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

Secrets are so often getting out. Why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone, ”according to Shah.

He added that talkative people could let secrets slip out. But this doesn’t mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

Shah said that to judge whether to tell someone a secret, you’d better put yourself in their position, Think about how you would feel to be told that you mustn’t give the information away. Shah also recommended that if you accidentally give up someone’s secret you should come clean about it. Let the person know that their secret isn’t so secret anymore.

2 . How do the world’s only flying mammals communicate? Researchers have observed young bats adopting new “dialects” simply by hearing them repeatedly, making them one of the few animals known to have a capacity for vocal (声音的) learning. “These bats may help us clarify the evolution of speech acquisition (习得) skills,” says Yosef Prat, a PhD at Tel Aviv University (TAU).

For one year, researchers raised 14 Egyptian fruit bat pups with their mothers in controlled area, exposing each young bat to two different vocalizations: the natural call of its mother and a separate recording that varied in pitch (音高) or frequency. They found that the pups in each group developed a dialect like the recording. “The general assumption in this field is that most animals develop their born vocalizations regardless of what they hear, and that human vocal learning abilities have developed during evolution,” says Mr Prat. “The finding that bats learn the common dialect in their rest place was unusual.”

Scientists know little about the origin of spoken language, which is believed to have appeared in humans within the past 500,000 years. Dozens of theories attempt to explain the complexity of this skill, but none have done so conclusively.

“Studying vocal communication and vocal learning in animal models is a very useful way to approach the problem,” says Olga Feher, an assistant professor at the University of Warwick in England.

But animal vocalizations and human speech are very different things, says Jamin Pelkey, a professor at Ryerson University. “All species communicate. Unlike other animals, though, human beings are able to use sound patterns for functions that are far stranger—functions that are imaginative, theoretical, and critical. When speech is involved in these stranger functions, that is what we mean by spoken ‘language’.”
