With courses on David Beckham and Harry Potter on offer at famous universities, it comes as no surprise that students are now able to learn the art of the perfect selfie(自拍）.
The concept of taking selfies gained great popularity. It soon exploded on the Internet, and people started crazily to take images that had them as the primary item of focus. The trend became so popular that it even inspired a song,“SELHE” by the Chainsmokers, which racked up 267 million views on YouTube. In fact, Twitter declared 2014 as “the year of the selfie”.
Just like the art of photography can be studied and improved, City Literary Institute, a well-known college in London, felt it needed to educate people on the fine art of taking the perfect selfie and officially started to offer a first-ever course on that.
The four-session course will cost £132 (£106 for seniors), but the fee won’t even include a free selfie-stick, a tool that is rapidly gaining acceptance for serious selfie-takers. It is open to all enthusiastic and self-obsessed photographers.
As part of the new course, self-absorbed photographers will be taught “valuable life skills^ to prepare themselves to face a world which could present a photo opportunity at any point. Apart from offering the much-needed but seldom-sought guidance on the best angles and lighting, the course promises to improve your critical understanding of the “selfie”. There will also be a brief exploration into the concepts of “identity, self-hood and memory” as well as the opportunity to “develop new ideas to you’re your photography more relevant to your aims,'
But the selfie enthusiasts must be prepared to share their photos, as organizers said a critique(评论）of students’ work would form an important role in the learning process.

Loneliness is like a disease, and what’s worse, it’s contagious. It can spread from one person to another, according to the recent research that stresses the power of one person’s emotions to affect even people they don’t know.
The new analysis, involving 4,793 people who were interviewed every two years between 2005 and 2015, showed that a friend of a lonely person was 52% more likely to develop feelings of loneliness by the time of the next interview. A friend of that person was 25% more likely, and a friend of a friend of a friend was 15% more likely.
''Loneliness is not just the property of an individual. It can be transmitted across people—even people you don’t have direct contact with,” said John T. Cacioppo, a psychologist of University of Chicago who led the study published in the December issue of the Journal of Personality and Social Psychology.
Loneliness has been linked to medical problems, including depression, sleep problems and generally poorer physical health. Identifying some of the causes could help reduce the emotion and improve health, experts said.
Although the study did not examine how loneliness spreads, Cacioppo said another research has provided clues. “Let’s say for whatever reason you get lonely. You then interact with other people in a more negative fashion. That puts them in a negative mood and makes them more likely to interact with other people in a negative fashion and they minimize their social ties and become lonely,” Cacioppo said.
According to Cacioppo, loneliness spread more easily among women than men, perhaps because women were more likely to express emotions.
Lonely people become less and less trusting others. This makes it more and more difficult for them to make friends—and more likely that society will reject them. Therefore, it is important to recognize and deal with loneliness. Cacioppo emphasizes people who have been pushed to the edges of society should receive help to repair their social networks.

A. Refuse the help given by others.
