Many of us still tend to think that emotions can affect reasonable thought，and sometimes land us in trouble. But in recent years psychologists have taken quite a different view. Keith Oatley，Professor of Psychology at Glasgow University，is involved in the research which shows the fundamental importance of emotions.

    He believes we are very ambivalent about them：we think of our emotions as being unreasonable，but we also consider them as essential to being human. For example，Mr. Spock，a character in the television series Star Trek，is super­intelligent and he has no emotions at all. However，he is never made captain of the spaceship. Maybe，this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.

    As Professor Oatley points out，our emotions have very important functions，for example，fear. If we cross the road and a car approaches，we usually stop moving or step back. We stop what we are doing，check what we have done and pay very careful attention to the environment. The emotion of fear makes us take this small series of actions which,on average, help protect our safety.

    On the other hand，if things are going well and small problems come up，we find we can solve them with the resources we have to hand. As a consequence, we tend to feel happy and usually continue doing the job.

    Anger is an emotion that tends to occur when someone is preventing us from doing something. Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person，or to try harder，and so on.

    Professor Oatley believes emotions generally occur at these important moments in actions. With fear and anger our emotions make us decide to start doing something else, while with happiness they “suggest” we continue what we are already doing.

    Chinese colleges have come up with an unusual way to help freshmen settle in. They turn their gyms into campsites for moms and dads, some of whom have traveled thousands of miles across the country, to say goodbye.

For the past five years, Tianjin University in northern China has provided free accommodation for parents in what it calls "tents of love". Other schools let parents sleep on mats in school gymnasiums.

    "Going to college is a life moment and my parents didn't want to miss that," said Zhang Jinqi, a freshman at Tianjin University majoring in applied chemistry. His parents traveled with him on the 19-hour train journey from Jiangxi Province in southern China.

    Images of school gyms packed with parents have been widely shared on Chinese social media prompting a debate on whether China's only children are too coddled.

    Some have voiced criticism of Tianjin University, saying that they think both the parents and the children should be more independent.

    Xiong Bingqi, the deputy director of think-tank 21st Century Education Research Institute，thinks the problem is overstated. "It has always been a problem in China that at the start of every school year, colleges are packed with parents who come along to drop off their children and stay with them," he said. "For some families, it's their way to celebrate the first-ever family member who's able to go to college," Xiong added. "There's nothing wrong with sharing the happiness."

    Zhang's father said the decision to escort their son was a no-brainer. He and his wife are among the many "campers" who sleep in the 550 temporary tents set up in the Tianjin University gym.

    "My child has lots of luggage and we also want to go traveling," said his father Zhang Yonghui. "The hotels nearby are fully booked so I have to sleep in the tents."

    Their son also shrugged off the criticism although he said he was looking forward to living on his own for the first time. "Being accompanied by my parents doesn't mean I'm spoiled."

    Making friends is a skill like many other skills. It improves with practice. If you want to meet people and make friends，you must be willing to take some actions. You must first go where there are people. You won't make friends staying home alone. Join a club or a group. Talking with those who like the same things as you do is much easier. Or join someone in some activities. Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it's human nature to feel a bit uncomfortable about the unknown. Most of our fears about dealing with new people come from doubts about ourselves. We imagine other people are judging us or finding us too tall or too short，too this or too that. But don't forget that they must be feeling the same way. Try to accept yourself as you are and try to put the other person at ease. You'll both feel more comfortable.

    Try to act self­confidently even if you don't feel that way. When you enter a room full of strangers，such as a new classroom，walk tall and straight，look directly at other people and smile.

    If you see someone you'd like to speak to，say something. Don't wait for the other person to start a conversation.

    Just meeting someone new does not mean that you will make friends with that  person—friendship is based on mutual liking and“give and take”. It takes time and effort to develop.

    There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

    People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing (批评) and being disliked is perhaps taken up by imitation (模仿). It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact (接触) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

    I travel a lot, and I find out different "styles"(风格）of directions every time I ask "How can I get to the post office?"

    Foreign tourists(游客) are often confused(困惑)in Japan because most streets there don't have names; in Japan, people use landmarks(地标)in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."

    In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."

    People in Los Angeles , California, have no idea of distance on the map; they measure(度量) distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it' is about five minutes from here." You say, "Yes, but how many miles away is it ?"They don't know.

    It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!
