Whether the eyes are 'the windows of the soul' is debatable; that they are intensely important in interpersonal communication is a fact. During the first two months of a baby's life, the stimulus that produces a smile is a pair of eyes. The eyes need not be real: a mask with two dots will produce a smile. Significantly, a real human face with eyes covered will not motivate a smile, nor will the sight of only one eye when the face is presented in profile. This attraction to eyes as opposed to the nose or mouth continues as the baby matures. In one study, when American four-year-olds were asked to draw people, 75 percent of them drew people with mouths, but 99 percent of them drew people with eyes. In Japan, however, where babies are carried on their mother's back, infants do not acquire as much attachment to eyes as they do in other countries. As a result, Japanese adults make little use of the face either to encode(把…编码)or decode(解码)meaning. In fact, Argyle reveals that the 'proper place to focus one's gaze during a conversation in Japan is on the neck of one's conversation partner.' The role of eye contact in a conversational exchange between two Americans is well defined: speakers make contact with the eyes of their listeners for about one second, then glance away as they talk; in a few moments they re-establish eye contact with the listeners or reassure themselves that their audience is still attentive, then shift their gaze away once more. Listeners, meanwhile, keep their eyes on the face of the speaker, allowing themselves to glance away only briefly. It is important they be looking at the speaker at the precise moment when the speaker re-establishes eye contact: if they are not looking, the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will terminate the conversation. Just how critical this eye maneuvering is to the maintenance of conversational flow becomes evident when two speakers are wearing dark glasses: there maybe a sort of traffic jam of words caused by interruption, false starts, and unpredictable pauses.

Body language is the quiet, secret and most powerful language of all! It speaks 21 than words. According to specialists, our bodies send out more 22 than we realize. In fact, non-verbal (非言语) communication takes up about 50% of what we really 23 . And body language is particularly 24 when we attempt to communicate across cultures. Indeed, what is called body language is so 25 , a part of us that it's actually often unnoticed. And misunderstandings occur as a result of it. 26 , different societies treat the 27 , between people differently. Northern Europeans usually do not like having 28 , contact (接触) even with friends, and certainly not with 29 . People from Latin American countries 30 , touch each other quite a lot.

The list of ills attributable to obesity keeps growing: Last week, obese people were accused of causing global warming. This 1 comes from Sheldon Jacobson of the University of Illinois, US, and a doctoral student, Laura McLay. Their study 2 how much extra gasoline is needed to haul fat Americans around. The answer, they say, is a billion gallons of gas per year. It 3 an extra 11 million tons of carbon dioxide. There have been 4 for taxes on junk food in recent years. US economist Martin Schmidt suggests a tax on fast food 5 to people's cars. 'We tax cigarettes partly because of their health cost,' Schmidt said. 'Similarly, leading a lazy lifestyle will end 6 costing taxpayers more.' US political scientist Eric Oliver said his first 7 was to laugh at these gas and fast food arguments. But such 8 are getting attention. At the US Obesity Society's annual meeting, one person 9 obesity with car accident deaths, and another correlated obesity with suicides. No one asked 10 there was really a cause-and-effect relationship. 'The funny thing was that everyone took it 11 ' Oliver said. In a 1960s study, children were 12 drawings of children with disabilities and without them, and a drawing of an obese child. They were asked 13 they would want for a friend. The obese child was picked 14 . Three researchers recently repeated the study 15 college students. Once again, 16 no one, not even obese people, liked the obese person. But, researchers say, getting 17 is not like quitting smoking. People struggle to stop smoking, and, in the end, many succeed. Obesity is 18 .

One of my wonderful memories is about a Christmas gift. Unlike other gifts, it came without wrap(包装). On September 11, 1958, Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying, 'I promised you a gift, and here it is.' What an honor! I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories. I told it over and over how much I loved it! One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I head mum and Dad whispering such words as 'hopeless', 'pitiful', and 'dying', which sounded ominous. 'Christmas was coming, don't expect any presents this year' Dad said, pointing at the socks I hung in the living room. I'd never seen him cry before. The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say, 'What? He's all right?'. He hung up and shouted upstairs. 'The hospital said we can bring Richard home!' 'Thank god!' I heard Mum cry. From the upstairs window, I watched my parents rush out to the car. I had never seen them so happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I ran downstairs. My socks still hung there flat. But I knew they were not empty: they were filled with love!
