Researchers who study relationships have discovered that a big difference between those who make new friends easily, and those who don’t, is that socially successful people tend to make eye contact with their conversation partners much more frequently than those who are less successful socially. In fact, you may be able to become much more socially successful by making this one simple change to your behavior.
Most Americans prefer to have a lot of eye contact when they are talking with someone. When a person doesn’t make eye contact with them, they tend to think that the person is hiding something or the person doesn’t believe in himself/herself.
When you are having a conversation and you want to leave a friendly impression, be sure to keep looking at that person frequently while you are talking. If it really bothers you to look directly into another person’s eyes, you can gaze generally at, not above, the eyebrow area or the bridge of the nose; this is close enough to the eye region that you will appear to be looking at the person’s eyes. But neither the hair or the shoulders have the same effect. Don’t stare at other people too intensely, otherwise, you will look aggressive(攻击性).
Keep the majority of your focus on the other person. If you glance around the room too much, or look too frequently at other people, your conversation partner may guess that you are looking around for someone else you would rather talk with.
You can lighten your nervousness by smiling more often, nodding, and by gazing at the entire face as well as the eyes. In addition, you can frequently look away for very short periods.
When people get the sense that you are really paying attention to them, they will be much more likely to want to have conversations with you!

Health experts have discovered that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight.
Because you feel full sooner, you eat less of your main course.
The soup regime（养生法）was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls.
They found that when people ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup.
But those who favor creamy soups should be careful．Researchers stressed the soup must be low-calorie and based on stock（菜汤）, not cream.
All of the soups tested in the study were made from identical ingredients - chicken stock , broccoli（硬花甘蓝）, potato, cauliflower（菜花）and carrots.
They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed soup.
Scientists thought that thick soups with chunks of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect.
The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part-funded by the National Institutes of Health.
