Accepting an invitation is a good way to develop relationships. But sometimes we have to say no to the offer for some personal reasons.     1    

Weigh (权衡) the importance of the invitation.     2     Being invited by your boss (上司) is different from being invited by your friend. You should think about why you are invited and what may happen if you don’t go.

    3     If someone invites you to some great event, you should thank the person for his consideration (考虑).

Tell the real thoughts. It is the right thing to give the person a yes or no answer.     4     But you can let the person know you are interested in accepting his invitation.     5

Social media allows people to keep in touch with friends, family and the people around the world with like-minded interests, and share their own thoughts, personal updates, and opinions online. However, using social media too much and posting many selfies (自拍) have caused a rise in narcissism, according to a new study. Narcissism is when someone becomes very selfish and believes they are very talented and beautiful. They need attention from other people and think they are better than everyone else.

Researchers at universities in Swansea and Milan found that heavy users of social media sites like Facebook and Twitter showed a 25 percent rise in narcissism in just four months. The researchers studied how 74 people aged 18 to 34 used social media and looked at how their personality changed. They said that posting selfies seemed to increase levels of narcissism in a way that text messaging does not. Those who used social media too much, through posting pictures, showed an average 25 percent increase in such narcissistic personality over the four months of the study. Only one of them in the study didn’t use social media, and others’ average use was around three hours a day, not including usage for work. Some said that they used social media for as much as eight hours a day for non-working reasons.

More than two-thirds of the participants at the beginning used social media for posting pictures. Professor Phil Reed, from the Department of Psychology at Swansea University, said, “There have been suggestions of links between narcissism and the use of selfies on social media, such as Facebook, but until this study, it was not known if using such social media is related with the growth in narcissism.”

The results of this study suggest that posting selfies can increase narcissism. Professor Read said that about 20 percent of people may be at risk of developing narcissism. This is because they want attention and likes from other people after they post a selfie. They also want to show others how their life is better or how they are more beautiful or attractive. They might feel good at the moment, but in the long term, it only serves to drive good people away from them, have negative effects on their success, and leave them weak and at risk.

Luoshifen is also called the river snail rice noodles. It is made by boiling rice noodles with pickled（腌制的）bamboo shoots, fresh vegetables and river snails. The dish is sour, salty and smelly. Some people don’t like its strong smell when they first try it. But many say they can never forget its magical taste.

This dish first appeared in the southern Chinese city of Liuzhou in the 1970s. At first, it was only a local street snack. People outside the city knew little about it. In 2012, a Chinese food TV show, A Bite of China, introduced luosifen to more people.

To make delicious river snail rice noodles, you need to pickle the best sour bamboo shoots. The best time to get them is spring. Peel off their shells（外壳）and cut them into pieces, then pickle them with salt and water in a jar for about one month. You can use them when a sour smell starts coming out.

Over the years, luosifen has often appeared in food bloggers’ videos. It has become one of the most popular online snacks among young people. From a local snack to an “online celebrity”（名人）, it has won the stomachs and hearts of many!
