Scientists have discovered a special biological behavior in dolphins(海豚) that could lead to a treatment for late-onset diabetes(晚发的糖尿病) in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.
The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.
If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity(肥胖).
The tissues of people with type 2 diabetes have become resistant to insulin(胰岛素)so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys(肾脏) and nerves and contribute to 5% of all deaths, according to the World Healthy Organisation.
Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analysed 1,000 blood samples(样本) from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism(新陈代谢)changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.
“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.What’s the main idea of the passage?

Destiny and Personal Responsibility
One important variable affecting communication across cultures is destiny(命运)and personal responsibility. This refers to the degree to which we feel ourselves the masters of our lives, contrary to the degree to which we see ourselves as subject to things outside our control. Another way to look at this is to ask how much we see ourselves able to change and act, to choose the course of our lives and relationships. Some have drawn a parallel between the personal responsibility in North American settings and the view itself. The North American view is vast, with large spaces of unpopulated land. The frontier attitude of “King” of the wilderness, and the expansiveness of the land reaching huge distances, may relate to generally high levels of confidence in the ability to shape and choose our destinies.
In this expansive land, many children grow up with a heroic sense of life, where ideas are big, and hope springs forever. When they experience temporary failures, they encouraged to redouble their efforts, to “try, try again.” Action, efficiency(效率), and achievement are valued and expected. Free will is respected in laws and enforced by courts.
Now consider places in the world with much smaller land, whose history reflects wars and tough struggles: Northern Ireland, Mexico, Israel, Palestine. In these places, destiny’s role is more important in human life. In Mexico, there is a history of hard life, fighting over land, and loss of homes. Mexicans are more likely to see struggles as part of their life and unavoidable. Their passive attitude is expr4essed in their way of responding to failure or accident by saying “no mode” (“no way” or “tough lick”), meaning that the failure was destined.
This variable is important to understanding cultural conflict. If someone believing in free will crosses paths with someone more passive, miscommunication is likely. The first person may expect action and accountability. Failing to see it, he may conclude that the second is lazy, not cooperative, or dishonest. The second person will expect respect for the natural order of thins. Failing to see it, he may conclude that the first is forcible, rude, or big headed in his ideas of what can be accomplished or changed.

On Christmas morning, I went to the Cockhedge Mall. People there were all busy buying their last minute requirements. I needed to buy a birthday card for my son-in-law whose birthday is the 29th of December. Picking up a few more things as well as my cared I went to join the line for the express checkout which was for people who only had a few items in a basket and not a trolley load. This line was next to the Customer Service desk.
Seemingly waiting quite a long time, I was jogged out of my thoughts by a voice behind me making comments on the things I bought.
It was so funny when I realized that she was describing the contents of my basket. The owner of the voice was a very pretty young lady. I said to her that I was going to buy a box of Christmas cookies but the only ones left were not to my liking. The lady told me that just opposite Cockhedge in Superdrug they had lots of cookies. I said, “I’m not going to bother now. I had enough of shops and I’m going home.”
The assistant from the Customer Service came across at this time saying “If there is anyone in the line with a few items in their basket, none of which needed to be weighed, I will check out their groceries at the desk.” Because I had the sprouts which needed to be weighted, the young lady accepted the offer and walked away waving goodbye.
Eventually my turn came at the checkout. I was walking away when I met my new friend once again who handed me a beautiful box of Christmas cookies. With a big hug she said “Hope you have a lovely Christmas.” She had been into Superdrug to buy me the cookies while I was still queuing in Cockhedge.
What a generosity to a stranger! I was so surprised you could have knocked me down with a feather. My Good Samaritan would never know what a joyful Christmas day I had with my family. Telling them this story, as we ate around the table, kept everyone spellbound..

In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied.Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories.She wants to enter one of her stories into a writing contest, a competition she won last year.
As a writer I know about winning contests, and about losing them.I know what it is like to work hard on a story only to receive a rejection slip form the publishers. I also know the pressures of trying to live up to a reputation created by previous victories.What if she doesn't win the contest again? That's the strange thing about being a parent.So many of our own past scars and dashed hopes can surface.
A revelation (启示) came last week when I asked her, "Don't you want to win again?" "No," she replied, "I just want to tell the story of an angel (天使) going to first grade.”
I had just spent weeks correcting her stories as she naturally told them.Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts (冲突) and endings for her tales.The story about a fearful angel starting first grade was quickly "guided” by me into the tale of a little girl with a wild imagination taking her first music lesson.I had turned her contest into my contest without even realizing it.
Staying back and giving kids space to grow is not as easy as it looks.Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my daughter's experience.
While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help when asked.All the while I will be reminding myself that children need room to experiment, grow and find their own voices..

Another food which is closely associated with Americans is apple pie.Apple pie is often served hot with a spoon of ice cream or a slice of cheese at the end of the biggest meal of the day—dinner, and it is a favorite dessert throughout the nation.If a person is typical of Americans, we can say, "He is as American as apple pie."
It is true that the apple and apple pie do not originate in America, but the expression "as American as apple pie" is not the product of a pure imagination.As early as 1625, the English colonists, having brought orchards (果园) on this new land and in most of the colonial times, the apple was a main material of both plain and fancy cooking.The first Massachusetts governor, William Endicott, was one of many keen apple planters who helped to lay the foundations for today' s apple-growing industry in America.
A major attraction of the apple for the colonists was that it could be made into cider (苹果酒). Like most Europeans, English colonists held a strong suspicion (怀疑) of drinking water, and since grape growing was hindered by plant peats, cider became an alternative to wine.Cheap and easy to produce, it was the American drink of first choice well into the nineteenth century. Whether it was dried, raw or cooked, the apple also found its way into
numerous colonial dishes, including apple sauces, pudding, stuffing and many desserts.Therefore, the conclusion to be drawn here is obvious.The apple pie became known as American, not because it was invented on this land (since it was proved that Europeans had b
een eating apple pies for centuries), but because, thanks to the huge orchards in the states of Washington and New York, America became the world's largest apple-producing nation.
