【题目】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 didnt 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.

B. They become resistant to insulin.

C. Their heart and kidneys are damaged.

D. They keep high levels of blood sugar.

【题目】Easy way to get healthy

I always hate the first few weeks of the New Year, mostly because people all say, “Let’s diet! It’s a new year!“

You can always choose to switch it up! 【1】 Here are some simple ways to get your health on all year round.

Switch out bad habits for good ones. 2 Do something as simple as swapping nighttime cookies for nighttime vitamins.

Catch some sleep. One of the most important things we can do for our minds and bodies is to make sure we’re getting enough sleep on a regular schedule. 3

Feed your mind. Keep your mind smart. Start a new hobby, read a book about something you don’t understand— and so on.

4 I’m not suggesting you take on a new sport. But taking the stairs, parking farther away, and finding a hobby you enjoy will allow you to be active.

Get organized. I’m not saying a whole repair of your entire world; start small. Organize a kitchen cabinet. Purge(清除) yourself of stuff you don’t need.

Get rid of the mess. That means your mind is included too! Make lists. Get a calendar and mark down important days. Clear your mind and your home. 5 .
