The human nose is an underestimated tool. Humans are often thought to be  1___ smellers compared with animals, but this is largely because, unlike animals, we stand upright. This means that our noses are  2 to detecting those smells which float through the air,  3  the majority of smells which stick to surfaces. In fact though, we are extremely sensitive to smells, even if we do not generally realize it. Our noses are capable of  4 human smells even when these are  5  to far below one part in one million.
　　  6    , some people find that they can smell one type of flower but not another, while others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate  7    smell receptors in the nose. These receptors are the cells which sense smells and send  8   to the brain. However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when  9    to it often enough.
　　The  10  for insensitivity to smell seems to be that brain finds it  11   to keep all smell receptors working all the time but can  12  new receptors if necessary. This may also explain why we are not usually sensitive to our own smells we simply do not need to be. We are not  13    of the usual smell of our own house but we  14    new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15   for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.

Girls that eat with their families are less likely to develop eating disorders, a study says.

New research shows girls who regularly have   21  meals are much less likely to adopt extreme weight control 22  such as vomiting (嘔吐), using laxatives (瀉藥)or diet pills.

A study  23  more than 2500 American high school students found that girls who ate five or more family meals a week had a much healthier 24  with food in later life.

Regular family meals were found to have a protective effect 27  the girls’ age, weight, socio-economic status,  28 habits or relationship with her family.

Experts say doctors should  29  families to have dinner at the table  30  on the couch in front of the television to 31serious eating disorders.

Belinda Dalton, director of eating disorders clinic The Oak House, said  32  with family helped "normalize"(正�；�) young people's relationship with food.

"When the young are feeling that they're not dealing properly, they  33  something that they can control and food is something  34   and accessible for them to control. 35  , if they're sitting with their family on a regular basis then their family can be more in  36  of their eating," Ms Dalton said. "It's about young people feeling  37  their family and that builds self-esteem (自尊) and sense of 38  and that works very actively against someone developing an eating disorder."

An eating disorders expert, Kirsty Greenwood, said meal times were often difficult for sufferers. "It's typical that they feel very   39  of their eating habits and often won't eat with other people. Perhaps it's because they haven't  40  the importance of the family meal in their growing up," she said.

I recently overheard something that surprised me. I heard that people who win the lottery (彩票) are1for about 3 weeks. And then they go back to their2state of being before they won the money.I3that they would have been happy for a much longer time.
The reason for this is that4we try to change how we feel by using something outside of ourselves，like winning the lottery，or getting a new car or house，it never5.The resulting feelings of happiness are often fleeting (飛逝的).We cannot6them for very long.In some way，it may be a good thing.It reminds us that happiness really does come from within and is7to us at any moment.True happiness has8to do with what is happening outside；it is an inside job.Happiness is a9.
We can make the decision to be happy for one day，when we10in the morning，every morning.We can find something that brings us great11，like sitting outside in the garden under an old tree and12the birds sing，or watching the dog or cat play，and just13the moment.It is our14state and we need only allow it in.At any moment，we can15，take a deep breath，and remember who we really are，and why we came here，and that truly is to16joy and the aliveness of being.
“Happiness is like a butterfly which，when run after，is always17our reach，but，if you will sit down18，may fall upon you，” said Nathaniel Hawthorne，an American novelist.So，today，no matter what is going on in your own19，stop and take a few moments to breathe deeply and just20to be happy，whatever that means to you.
