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 Organization.
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 analyzed 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?

There are stock markets (股票市场) in large cities in many countries. Stock markets in Paris,
London, Tokyo, Shanghai and New York are among the largest and most well-known. The stock, also called stock exchange, is a place where people can buy or sell shares of a factory or company. And each share means certain ownership(所有权) of a factory or company.
Different people go to stock markets. Some are rich, who want to get more money than they
have. Others are not very rich, who buy stocks to try to become rich. Still others buy stocks as
part of their plan to save money.
Of course, investing (投资) money in the stock market is not the safest way to make money.
No one can tell exactly whether the shares will be doing well. The factory or company may
do badly. Then the stocks will go down, and the investors will lose money. The stock may go up or down for a number of untold reasons. Everyone wants the stock to go up, but sometimes even if a factory or company does a good job, the stock may still go down.
Going to the stock market is often like gambling (赌博). All want to make money by
“gambling’ in the stock market. Factories and companies that need money are pleased that so many people are ready to “gamble”. Indeed, the stock market is an attractive(吸引人的) but complex part of the business world.If you are a good investor, ________ in the stock market.

A young boy was sitting in the back seat of the car eating an apple. He asked his father, “Why does my apple turn brown?” His father answered, “When the skin is removed, air reaches the flesh of the apple causes oxidation. This changes the apple’s molecular structure and results in a brownish color.”The boy asked,“Dad，what are you talking about?”
I know how that boy feels. Sometimes I want answers to some of those confusing questions that we all meet with, such as how to get through difficult times or what to do in a tough situation. I just want to get it right.
The problem is that I don’t always have the answer I need. Nobody else seems to have them, either. So I go on making mistakes and think that I’ll never get it right.
Often I didn’t know what to do. I often made poor choices, but I gradually improved. Then I realized that I don’t HAVE TO always get it right. I don’t have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on.

Our interpersonal skills have a great effect on success in our daily lives. This appears not only in the workplace where we can make more money or enjoy our job more, but also shows itself in marriage, raising a family and the ability to reach goals in almost every area of life. Interpersonal skills come into play when our flight is cancelled and we need to make other arrangements. They come into play when a marriage is threatened by financial challenges or infidelity(不忠).
Our communication skills even matter when we are in traffic and we need to make a decision about how to respond to other drivers. Communicating with others becomes inseparable from having a good day, or a bad day not only in how we begin communication, but in how we react to the communications of others who are having a difficult time.
It can make a difference in saving a marriage or getting a divorce, celebrating a rise or getting fired, and even having your eggs cooked as the way you like at the local restaurant. Many wise men and women have stressed the importance of dealing with others in a skillful manner.
Getting feedback(反馈意见) from others can be of great value in improving our interpersonal communication skills. Often, however, others are not skilled at giving feedback. When we get negative results, they rarely include the details we need in order to improve our interpersonal skills.
Since life improves so much with greater communication skills, getting feedback and an opportunity to improve would be not only life-saving for pilots, but labor-saving for the rest of us.
