17．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 4million 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 an 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．

2．After almost an entire year of saving from shopping and vacationing，you find the numbers reflected by your bank account meet your heat's desire．Now the most important question comes what to do with the earnings？Should you fulfill dreams of the present，or keep saving it for a rainy day？
Our elders always try to teach us the value of money and its uncertainty．One may be on a winning situation now，but it will not always be so．One will have days when there will be no sunshine but only rain，and their luck will hide behind those thick grey clouds．Save for those rainy days，they say．Do not spend too much，live within a budget，stay away from credit no matter how small and save for the future．Since the very first time we earn our own money from a summer job or earn our first salary，the lessons start．
In fact，the pocket money that we receive when we are children starts the process of learning how to best manage one's manage one's money．Future，future，future，that's all they talk about，but what about the present？What about our current desires，wants and needs？Wasn't our present once our future？
One day when I have enough money，I will buy myself a car．One day my luck will shine．One day I will have enough money to travel the world．Then，once we do earn enough money from saving，tomorrow's plans start shadowing our present ones．
However，is it wise to keep living for that future？Will we still enjoy or even be able to backpack in our 50s？What will be the use of those professional cameras when pains take over our joints and our mind grows dull？Will our liver be able too handle the meat and alcohol in our advanced age？What if our life ends suddenly？How will we ever enjoy our present if we are constantly living for the future？
I say enjoy the most comfort but also keep enough for your necessities，and stay happy with your present but with a plan for the foreseeable future．Beyond that，life is not in our control and we shouldn't worry about the unseen．Life is for the living，so live it wisely．
