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.

Yasuda is 95 years old. Looking for easier ways to search the Web and send email, he bought Apple’s iPad. The company has sold 3.27 million iPads since they entered the market in April. Although it’s impossible to know with certainty how many seniors (老年人) are buying them, evidence suggests that it’s a hit with seniors.

The iPad’s intuitive interface (直观界面) makes it attractive to seniors around the world, says Takahiro Miura, a researcher at the University of Tokyo. “The iPad is a good tool for seniors because it’s very easy to use,” he says. “Unlike the PC, it doesn’t require former knowledge.”

James Cordwell, a researcher in London, says the iPad’s popularity with seniors is helping Apple reach beyond its traditional base of young customers. “The world’s population, especially in developed markets, is getting older. It’s probably a market where Apple has least entered,” Cordwell says. Senior users are “a key source of growth for them in the future.”

Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes come with getting older. “Trying new things like that is good mental exercise,” he says.

1.Which of the following is NOT an advantage of the iPad?

A. It has intuitive interface.

B. It is easy to operate.

C. Beginners can use it without similar experiences.

D. People can use it as a way to do mental exercise.

2.What can we learn from the text?

A. People above thirty are Apple’s largest customer group in Japan.

B. The traditional customers of Apple’s products are usually the young.

C. Seniors will soon grow into Apple’s largest customer group.

D. Seniors in Japan are fond of buying latest hi-tech products.

3.What is the text mainly about?

A. iPad leading Apple to seniors.

B. iPad influencing the customer group.

C. iPad’s arrival causing Japanese to think.

D. iPad beating the traditional PC

Sure, it’s good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

And yes, it’s good to get along with your teacher because, in general, it’s smart to learn how to understand the different types of people you’ll meet throughout your life.

“But really, there’s one super-important reason why you should get along with your teacher. When you do, learning bursts right open,” says Evelyn Vuko, a longtime teacher who writes an education column(专栏) called “Teacher Says” for the Washington Post newspaper.

In fact, kids who get along with their teachers not only learn more, but they’re more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school life, such as bullying.

As a kid in a primary or middle school, you’re at a wonderful stage in your life. You’re like a sponge (海绵), able to absorb lots of new and exciting information. On top of that, you’re able to think about all this information in new ways. Your teacher knows that it, in most cases, is very excited to be the person who’s giving you all that material and helping you make it. Remember, teachers are people, too, and they feel great if you’re open to what they’re teaching you. That’s why they wanted to be teachers in the first place—to teach!

Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren’t going well, they won’t learn as well and won’t enjoy being in class.

1.In the passage, the author mainly talks about _______.

A. how to get along well with others

B. the importance of a good relation with teachers

C. how to make the time in the classroom more pleasant

D. how much the students are expected of to get along with teachers

A. you find an opening to learning

B. learning becomes easier for you at once

C. there’ll be more problems with learning

D. there’ll be no problems at all with learning

3.According to the passage, which of the following statements is TRUE?

A. The more questions you ask, the higher marks you will get.

B. Many kids can do well without a good relationship with teachers.

C. If you get on well with your teachers, you must have a good result in exams.

D. if you have a good relationship with your teacher, you can turn to him when in trouble.

4.Which of the comments is FALSE on teachers and their work according to the passage?

A. Teachers sometimes have the same feelings as students do.

B. Teachers are excited even if you wouldn’t like to accept their teaching.

C. Though few, there are still some students who can learn even if they don’t like the teacher.

As a recipe for losing weight, taking a slice of chocolate cake at breakfast would seem an unlikely fantasy.

A team from Tel Aviv University found that eating pudding as part of a balanced 600-calorie breakfast that also included proteins and carbohydrates (碳水化合物), could help dieter to lose more weight---and keep it off in the long run.

Attempting to avoid sweets entirely can create a psychological addiction to these same foods in the long term. So adding desserts to breakfast can control craving(渴望) throughout the rest of the day.

Over the course of a 32-week-long study, participants, who added desserts to their breakfast lost about 40 pounds more than a group that avoided such foods. What’s more, they kept off the pounds longer.

A meal in the morning provides energy for the day’s tasks, aids in brain functioning, and kick-starts the body’s metabolism (新陈代谢), making it decisive to weight loss and maintenance. And breakfast is the meal that most successfully regulates ghrelin, the hormone that increases longer. While the level of ghrelin rises before every meals, it is controlled most effectively at breakfast time.

The researchers hoped to determine whether meal time and composition had an impact on weight loss in the short and long term, or whether it was a simple matter of the caloric count.
