For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but to no avail. It was only when I turned to meditation(沉思)for a solution that the answer came to me: turn to nature!

The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain(限制) our own spirits, which only leads to depression and stress.

Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre.

If you feel a little low in spirit and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.

Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.

Dr. Bramlet, a children’s heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way.

“And so what we’ve done with the printed models? We’ve pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy（解剖）.”

A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy.

Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster（石膏）form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. “When we’re done with the model and made our decision, we want to be able to go back to the source image and confirm those findings,” he says.

Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby’s heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.

Kathy Magliato is a heart surgeon at Saint John’s Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients.

“I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I’m seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives.”

Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

Chinese parents are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the US or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend unreasonable amount of money on education. Even poor couples will buy computers for their sons or daughters.

However, what most parents fail to see is that the best education they can give to their children is usually very cheap.

Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize though, is that today’s children lack self-respect and self-confidence.

The reasons are that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills: they need to be confident, happy and clever.

Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.

Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of confidence. These activities are not only teaching a child to work, but rather to think, and to use his mind. And that is more important.

I _____ through the hard time but for my teacher’s generous and timely help.

A. couldn’t have gone B. could go

C. mustn’t have gone D. hadn’t gone

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.

A. Humans get some idea of treating diabetes from dolphins.

B. Dolphins can switch into a diabetic-like state overnight.

2.The key to applying the finding to curing human diabetes lies in ____________.

A. Scientists have found a similar genetic switch in humans.

B. More British people will suffer type 2 diabetes due to obesity.

C. 2.2 million people with type 2 diabetes die in Britain every year.

D. Dolphins imitate diabetes to avoid a high blood sugar level.

4.What will happen to dolphins if not fed for a night according to Venn-Watson?

A. Their metabolism breaks down.

B. They become resistant to insulin.

C. Their heart and kidneys are damaged.

D. They keep high levels of blood sugar.
