Missing friends who live far away? Or just need a little family comfort after a long day? Sometimes you just need a hug(擁抱). And sometimes there’s just no one around to give you one. So what do you do? How about a virtual (虛擬的) hug?Scientists at the Massachusetts Institute of Technology (MIT) have invented a social media vest (社交背心) that allows people to give hugs to their friends, family and loved ones on Facebook.
The vest is called Like-A-Hug, which is connected(連接) with your Facebook page. Whenever Facebook friends “Like” a photo, video or anything you post on the network, a fan will blow air into the vest to give you a hug. Hugs can also be sent back to the sender by pressing the vest to lose air, according to the website of designer Melissa Chow.
She worked with Andy Payne and Phil Seaton at the MIT Media Lab to build the black vest, making the wearer “feel the warmth, encouragement, support, or love that we feel when we receive hugs.” Melissa Chow said, “We came up with the idea over a free talk about long-distance relationships and the disadvantages of video chat interfaces (視頻聊天界面) like Skype.”
Chow and her workmates actually finished work on the vest last year, but it’s only just recently drawn the attention of the public.
Chow provided no pricing or ordering information for the Like-A-Hug vest, so don’t expect to see people blowing up all over town just yet.
Although researchers believe that Like-A-Hug will cause a worldwide storm, a lot of people think it can’t take the place of the feeling of a real hug. Body temperature or the taste of hair and so on is far from what a social vest can match.
【小題1】What is the main purpose of the text?

In England recently three foreign gentlemen came to a bus stop and waited . About five minutes later, the bus they wanted came along. They were just going to get on when suddenly there was a loud noise behind them. People rushed onto the bus and tried to push them out of the way . Someone shouted at them. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreigners seem all at sea and looked embarrassed (窘迫的 . No one had told them about the British custom (習(xí)慣)of lining up for a bus that the first person who arrives at the bus stop is the first person to get on the bus .
　　Learning the language of a country isn't enough. If you want to have a pleasant visit, find out as much as possible about the manners and customs of your host country. You will probably be surprised just how different they can be from your own. A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table. The left hand is supposed to be used for washing yourself. Also in India, you might see a man shaking his head at another to show that he doesn't agree. But in many parts of India a shake of the head means agreement. Nodding (點頭) your head when you are given a drink in Bulgaria will most probably leave you thirsty .
　　In that country, you shake your head to mean 'yes'— a nod means 'no' . At a meal in countries on the Arabic Peninsula, you will find that your glass is repeated refilled as soon as you drink up . If you think that you have had enough , you should take the cup or glasses in your hand and give it a little shake from side to side or place your hand over the top.
　　In Europe it quite usual to cross your legs when you are sitting talking to someone even at an important meeting. Doing this in Thailand, however, could bring about trouble . Also, you should try to avoid (避免)touching the head of an adult (成人) ——it's just not done in Thailand .
