【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 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.

【题目】Mrs. Obama spoke to the graduates of Martin Luther King Jr. High School on Saturday in her only high school commencement（毕业典礼）speech this year. The ceremony took place in the gymnasium of Tennessee State University.

The first lady told the 170 graduates that she spent too much of her time in college focusing on academic achievements. While her success in college and law school led to a good job, she said, she ended up focusing on public service. “My message to you today is that don’t waste a minute living someone else’s dream,” she said. “It takes a lot of real work to discover what brings you joy and you won’t find what you love simply by checking mailboxes or surfing the net.”

She said MLK reminded her of her own high school experience in Chicago. “My No.1 goal was to go to a high school that would push me and challenge me,” she said. “I wanted to go somewhere that would celebrate achievement. Unfortunately, schools like this don’t exist for every kid.” she said. “You are blessed.”

The first lady told graduates that failure may be a part of their college lives and careers, and that how they respond determines what they will become. “That’s when you find out what you’re really made of in those hard times,” she said. “But you can only do that if you’re willing to put yourself in a position where you might fail.” Overcoming difficulties has been the mark of many great people, she said, “Oprah was demoted（降职）from her first job as a news reporter, and now she doesn’t even need a last name,” she said of media giant Oprah Winfrey “And then there’s this guy Barack Obama, I could take up a whole afternoon talking about his failures. He lost his first race for Congress”, the first lady joked, “and now he gets to call himself my husband.”
