Mobile Phone Manners

Mobile phones have changed the way we communicate (交流); they have also brought about problems in phone manners (礼仪). Gaik Lira, a Singapore-based advisor, has some advice on phone manners.

When dealing with missed calls, the person being called should return the call. "Calls should be returned as soon as possible, and no later than the following day. Anything later than that, and an apology or a reason for the delay should go with the call. "

Text messages should be kept short and to the point. If they go beyond four or five lines, call or e-mail instead. "The use of short forms should be among family members and friends, never in a business situation. "

Speak in a low voice as if you were talking to someone next to you. If the connection is bad, don’t raise your voice in order to be heard, simply move to another place where the connection may be better. And if that doesn’t work, tell the caller to call you back or offer to call at a later time.

When a conversation is cut off due to a bad connection, the person who started the conversation should call back. "It may be inconvenient for the other person to return the call, especially if it’s an unlisted number, or an overseas call. "

When running late for a date or meeting, it is acceptable to text to inform that you’ll be delayed. Messages should be apologetic. "A message like ’ Sorry. Will be about 30 minutes late due to flight delay’ is considered polite and thoughtful. "

Taking calls during meetings is only acceptable if you have informed the chairperson that you are expecting an urgent (紧急的) call. If you get an unexpected but urgent call, apologize to those present and offer a quick explanation as to why you have to take that call. Then leave the room to continue your phone conversation.

Different countries have different cultures. A same gesture may have distinct meanings in different countries. For instance, in Africa, people knock at the table with their fingers to call waiters which is considered as impolite in China. In western countries, if you make a circle with your thumb and the index finger (食指), and then raise the other three fingers, you are suggesting "OK". The same gesture, however, means "money" in Japan while makes Brazilian people feel insulted (受侮辱的). With that in mind, you’d better learn about their custom before travelling to foreign countries.

Greeting is an important part of communication between people. When greeting someone, Americans tend to hold out their hands and look directly into his/her eyes and then smile. However, sometimes such behavior might bring nothing but misunderstanding in other countries. A handshake might not be accepted and looking others right in the eye can have different meanings.

Asian people regard physical contact as embarrassing; therefore, they do not shake hands. They have their own ways of greeting people. For Japanese, a slight bow of the head is enough. In Korea, women do not shake hands or hug with people; while men might shake hands accompanied by nodding the head once. In western Asia, Muslims do not make body contacts with women yet hug is generally accepted among men. Same thing happens on eye contact. In many countries, people avoid direct eye contact to show respect. This can cause misunderstanding, too. In fact, some Asian students have been regarded as lacking respect for their American teachers exactly because they failed to make eye contacts with their teachers.

Though different cultures seem to have different ways of greeting, smiling is taken as the universal gesture of friendliness. Smiling indicates happiness or agreement (同意) and it can also be used to mean "Excuse me" or "Please". So when you are not sure what to do, just smile.

British scientists have been given ￡ 1 million by the European Commission to find out if a robot (机器人) can safely be employed to stir (搅拌) soup.

The research, based at the Bristol Robotics Lab (BRL), will look at the problems of a human and a robot working together in the same space; for example, in a kitchen where the service robot is performing a task such as stirring soup while you add cream.

Professor Chris Melhuish explained, "When we work with other humans, we are trying to understand facial expression, body movements, quality of voice, as well as sharing a goal and understanding and following spoken instructions. "

"For example, in the soup situation, not only does the robot need to know what the goal is ( making the soup) but he also needs to know how hard to stir the soup, what it means when you hold up your hand to say enough, to understand the look of pain on your face if you accidentally get wet with hot soup, and to stop stirring when told. The research aims to develop the rules we need to introduce this level of cleverness into service robots who are working closely with people. "

Professor Melhuish, of the BRL, said robots working in factories at present are kept behind gates for safety reasons--a measure that is not practical in the kitchen.

The research is a joint effort between robotic engineers and scientists from West of England and Bristol universities.

It’s 8.00 am. James Butters gives ]8-month-old Thomas his milk, then breakfast. After getting Thomas into his outdoor clothes, they head for the park to watch birds and play on the grass. With hitch time drawing near, they’re back home for an afternoon of drawing, playing with cars, maybe watching some children’s programs.

James isn’t Thomas’ dad. He is a nanny (保姆)--a man nanny, obviously, interestingly termed a "manny"--specially trained and in his third nannying position. At 27, he cares for Thomas, and another boy of a similar age. "It’s much freer than an office job," he says, "and you’re getting to see children develop and grow. You become very close to them, for sure. I don’t think I’m special or better than a woman nanny; everyone has their own method. But I’m unusual. Friends laughed when I started studying nursery nursing. In my class, I was the only man among 70 women. Somehow, I made it," he said.

Although it’s not yet common to find men in traditional (传统的) nannying courses, things are changing. In the United States, parents are employing young mannies, sometimes to care for babies, but more often as active role models to get junior away from the TV and the computer. From rollerblading (轮滑) friends to summer swimming mannies, these are the big brothers who are always willing to play, largely because they’re paid for it.

It is catching on here in Britain, too. Earlier this year, Nofland nanny college welcomed its first full-time man student, 19-year-old Peter Cummins in Wales. While some families find it difficult to accept the idea of a young man in a traditional nannying role, man nannies are increasingly popular.

Looking to improve your language skills, but you don’t have the time to go abroad to attend school More and more universities around the world are offering opportunities for students to get degrees online ( distance education) from the comfort of their own homes, and many of these colleges and universities are accredited (官方认可的), meaning that they have met certain standards of excellence.

If you decide to take language courses online (or any subject for that matter), be sure there are advantages in studying online. Its costs are usually lower, and you can study at your own pace (节奏) and you can easily get the materials 24 hours a day from almost any computer in the world. However, you won’t get the human interaction (互动) of meeting people face to face, as you would if you were attending a school abroad in person.

On the other band, the advantages of going abroad may include day-to-day chances to learn a new culture, to meet new friends with whom you can use and practice the language, and to see different parts of the world. However, there may be a number of disadvantages for some students, including high costs, time away from one’s school, family, or work life, and difficulty in getting used to anew culture and way of life.

Whatever you do, consider a distance education program that meets your educational needs, is what you can afford, and equally important, provides you with chances to grow beyond the classroom through cultural and educational activities.

Even if your child is an excellent student, you can’t expect that he will always dutifully do his homework. The following is some useful advice for helping them deal with their homework.

Set a regular time and place for study. Give homework its own special time and place, and if your child is in middle or high school, let her set her own timetable.

Take it step by step. Children may get overwhelmed (压倒) by too much homework they have to do. Encourage your child to calmly work out what needs to be done and how much time it will take, and then make a plan. Help your child break homework down into manageable steps.

Help out. You shouldn’t have to do your child’s homework or re-teach the material covered in class, but you can help out by showing your interest and by encouraging independent (独立的) problem solving.

Praise a job well done. Kids, no matter what their age, need to know that they are doing a good job. Praise them for their successes and encourage them to keep up the good work. A little praise will go a long way in building healthy study habits.
