Here is how your health risks increase at different BMIs(体重指数) if your waist circumference（腰围）is higher than 40 inches（102 cm） in men and 35 inches （88 cm） in women:
☆If your BMI is in the 18.5 to 24.9 range, or “Normal”, then a larger waist that is near or greater than 40 inches for men and 35 inches for women can indicate that you are at “increased” risk.
☆If your BMI is in the 25 to 29.9 range, or “Overweight”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “increased” risk. Above these sizes, the risk is considered “high”.
☆If your BMI is in the 30 to 34.9 range, or “Obese I”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “high” risk. Above these sizes, the risk is considered “very high.”
☆If your BMI is in the 35 to 39.9 range, or “Obese II”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “very high” risk. Above these sizes, the risk is still considered “very high”.
☆If your BMI is or in the 40 + range, or “Obese III”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “extremely high” risk. Above these sizes, the risk is still considered “extremely high”.

A world-famous Canadian author, Margaret Atwood, has created the world's first long-distance signing device(装置), the LongPen.
After many tiring……from city to city, Atwood thought there must be a better way to do them . She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here's how it works: The author writes a personal message and signature on a computer tablet(手写板) using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams(网络摄像机) and computer screens。
Work on the LongPen began in Atwood's basement(地下室). At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, teat runs w ere made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.
The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.
"It's really fun", said the owner of a bookstore, who was present for one of the test runs. "Obviously you can't shake hands with the author but there are chances for a connection that you don't get from a regular book signing..
The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, "It will be possible to go to places that you never got sent to before because the publishers couldn't afford it."

One night, when I was eight , my mother gently asked me a question I would never forget. “Sweetie, my company wants to me but needs me to work in Brazil. This is like your teacher telling that you’ve done and allowing you to skip a grade(跳级), but you’ll have to your friends. Would you say yes to your teacher?” She gave me a hug and asked me to think about it. I was puzzled. The question kept me for the rest of the night I had said “yes” but for the first time, I realized the decisions adults had to make.
For almost four years, my mother would call us from Brazil every day. Every evening I’d wait for the phone to ring and then tell her every detail of my day. A phone call, however, could never replace her and it was difficult not to feel lonely at times.
During my fourth-grade Christmas break, we flew to Rio to visit her. Looking at her large apartment, I became how lonely my mother must have been in Brazil herself. It was then I started to appreciate the tough choices she had to make on family and work. difficult decisions, she used to tell me, you wouldn’t know whether you make the right choice, but you could always make the best out of the situation, with passion and a attitude.
Back home , I myself that what my mother could do, I could, too. If she to live in Rio all by herself, I, too, could learn to be . I learn how to take care of myself and set high but achievable .
My mother is now back with us. But I will never forget what the has really taught me. Sacrifices in the end. The separation between us has proved to be for me.

When my father was celebrating a milestone (里程碑) birthday, I pulled together a surprise gift that he would never forget.
As he was approaching 60,1 had a firm idea: What if I could get the memories people had of him, put each one into an envelope - 60 in total - and have him open them, one by one, on his birthday? So I wrote an e-mail to family and friends, explaining my idea.
I sent the e-mail and waited. And then the replies started coming in and I was very, very surprised. There were so many memories, and they were all so lovely. They came from the '50s, '60s, '70s, from every decade（十年） between now and the day my dad was born. They came from my mother, my siblings, my grandma, my dad's friends from high school, his sister, my dad's first boss, a colleague at his first job, from people who hadn't seen my dad in 40 years, from people I myself hadn't even informed. They typed them and handwrote them. They mailed them and e-mailed them.
The night before Dad's birthday, my sister and 1 stayed up late, putting everything together with some
The next morning, after breakfast and presents and cake, we gave the pile of envelopes to him. "Just one more thing for you," we said.
It took him a long time to open them and read. Each one was a brief ticket to another time, a leap (跳跃) backward over years and decades. There was a lot of laughter and a few tears, too.
I was kind of sad when the project was over because it was great fun to collect these memories. It gave me a different picture of my dad.

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.
"Women tend to be social in their behavior. They often share with others. But men lend to be competitive. They are trying to improve their social status," said Professor Ryan.
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and
our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.
But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants（参与者）received oxytocin. The other half received placebo (安慰剂).
After a week, the two groups switched with participants. They went tlirough the same procedure with the other material.
Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.
The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal."What causes men and women to behave differently according to the text?
| A．Placebo. | B．Oxytocin. |
| C．The gesture. | D．The social status. |
What can we learn from Professor Ryan's previous experiment?
| A．Oxytocin affects our behavior in a different way. |
| B．Our body lets out oxytocin when we are deep in love. |
| C．Our body produces oxytocin when we feel unhappy about others' success. |
| D．Oxytocin improves our abilities to understand people's behavior differences. |
Why did Professor Ryan conduct the recent experiment?
| A．To test the effect of oxytocin on the ability to recognize social interactions. |
| B．To know the differences between friendship and competition. |
| C．To know people's different abilities to answer questions. |
| D．To test people's understanding of body language. |
The author develops the text by______.
| A．explaining people's behaviors |
| B．describing his own experiences |
| C．distinguishing sexual differences |
| D．discussing research experiments |
