A good night’s sleep can improve your mood and your memory. New data shows that getting enough sleep might also get your cuts to grow back together faster. In fact, sleep was more important than good healthy food in speeding wound growing back together.
This wasn’t what scientists had expected to see.
They had hoped to show that giving people the right type of food for good health and growth would make their skin wounds grow back together faster --- even in people who were prevented from having enough sleep. The scientists thought it should work because good healthy food keeps the body strong, helps repair injuries and guards against infection (感染).
Tracey Smith is a scientist at the U.S. Army Research Institute. She and her team studied three groups of healthy people who came to their lab to take part in tests. They gave each group small skin wounds.
* One group of 16 volunteers got a normal amount of sleep --- seven to nine hours a night. The other two groups of 20 people each got only two hours of sleep a night, for three nights in a row. To stay awake, the volunteers were asked to do things such as walking, playing video games, watching TV, sitting on an exercise ball or playing table tennis. Throughout the experiment, one of the sleep-losing groups got a healthy drink with protein and vitamins. The other group also got a drink: It looked and tasted the same but had no healthy chemicals in it.
Sleep clearly helped. People who slept normally got well in about 4.2 days. The volunteers without enough sleep took about 5 days. And getting better healthy food offered no clear benefit. What to make of the data
Sleep expert Clete Kushida didn’t find the results all that surprising. He is a doctor at Stanford University Medical Center in California. The idea that lost sleep harms the body is true.
Why didn’t healthy food help healing time? Smith can think of a few possibilities. The healthy drinks may have helped a little --- just not enough to show up clearly in the small numbers of men and women tested here. Different people need different amount of time to become better.
For people who can’t avoid losing sleep, scientists still don’t have a good way to help them. Smith says, “If you want to become better faster, your best bet for now is to get more ‘vitamin Z’.

“You are just like your mother.” This phrase is often said by many. As we grow older, we may notice that we’re getting more like our mother. Yet surprisingly, a new research has found that most people are more similar to their father. A team of scientists from the University of North Carolina School of Medicine in the US found that we inherit (继承) equal (同等的) amounts of genes from mother and father. But we use more of the DNA we inherit from our father.
The study helps us to explain who we are. And more importantly, it helps us to find out whether we are likely to develop illnesses. For example, if we inherit the gene of an illness from our mother, it may not be as strong as if we inherited it from our father.
“We know that there are 95 genes influenced by our parents”, said Professor Villena. These are called imprinted genes (印记基因). But now, the study has found that there are thousands of other genes that have come from our parents.
For the study, the scientists choose three different species of mice with different genes. The mice then gave birth to nine babies each. When they all reached adulthood, the team measured (测量) every single gene of their DNA. They found an imbalance that swung toward their father. Villena also said that the recent study was the first to show that mammals (哺乳动物) are more similar to their fathers than mothers. “This is an exceptional new research finding that opens the door to an entirely new area of exploration in human genetics,” he said.

【推荐3】“Humans can develop certain abilities we aren’t, born with by practicing animals’ movements,” the traditional Chinese Wushu lovers believed in the past—and still do today.
Chinese Five-Animal Exercises, also known as Wuqinxi, are the first complete set of qigong exercises following the movements of animals: monkeys, deer, birds, bears and tigers. They were created by one of the greatest doctors in Chinese history, Hua Tuo, more than 1,800 years ago.
The Five-Animal Exercises are well designed to help blood circulation, and let the energy go smoothly in the body so as to improve the health.
“The bear movements are good for the stomach. The tiger movements can reduce the pain in the back. The deer movements help reduce the fat around the waist. The bird movements can help keep our knees healthy and the monkey movements can be good for the heart.” said Hua Yi, the 59th inheritor of Wuqinxi.
For those new learners, the first few exercises might not go well. You may find it hard to focus. Wear comfortable clothes, keep peaceful in your mind, try to move slowly...Little by little, you’ll feel more and more harmonious with nature. You may even feel you become a tiger or a deer, walking in the forest freely.
These exercises need no tools and they are easy to learn. You can search online for the videos and practice them at anytime when you feel like relaxing your body and mind. Because it’s fun to practice and good for health, Five-Animal Exercises are becoming more and more popular in recent years, not only in China, but also in many other places of the world.

【推荐2】A young American doctor was sleeping when suddenly his doorbell began to ring. It was already midnight, but what could the doctor do? He had to get up, put on his coat and go downstairs.

“You are an octopus, Oliver. That’s special.” The sweet voice of Cherub, beautiful fish, always made Oliver feel better. Oliver looked up at the fish and smiled. Cherub suggested, “Let’s play hide-and-seek (捉迷藏).” They were having so much fun that they didn’t realize they had swum far from home. Suddenly, Cherub saw a large shark swimming above them. “It was Big White…the biggest, scariest animal in the sea,” she shouted to Oliver. Cherub was very scared. She looked at Big White hopelessly. And idea came to Oliver. He quickly gave out a very dark cloud of black water to the shark’s eyes. Then Oliver and Cherub ran back home safely.
“Are you OK?” asked Oliver. Cherub laughed happily, “That was the most interesting tip! You saved me just now.

【推荐2】Detective fiction is popular in many countries. There are two kinds: stories in which private detectives solve a crime, usually a murder; and stories in which a police detective solve a crime. Both kinds of detective story are equally popular.
The first private detective---PI for private investigator in the USA---was probably Arson Lupin, a Frenchman. However, stories about this detective are not read nowadays. For most people the first, and perhaps the greatest, private detective, was the Englishman, Sherlock Holmes, a character created by the author Sir Author Conan Doyle. All the Sherlock Holmes stories have been translated into most languages. The best known is the Hound of the Baskervilles.
The first police detective was probably Sergeant Cuff who solves the crime in the Moonstone, one of the first detective novels in English. The author, Wilkie Collins, was a close friend of Charles Dickens, the best English novelists of all the time.
Crime fiction has been as popular in the USA as in the UK, and some of the most famous American writers have written detective fiction. The most highly regarded is probably Raymond Chandler whose PI, Phillip Marlowe, is the archetype (典型的) private detective. Also popular, although not so well-written, are the Perry Mason novels by Erle Stanley Gardner.
After Conan Doyle, the most widely read private detective novelist is the English novelist Agatha Christie. She created two unforgettable characters--- Miss Marple and Hercule Poirot. Agatha Christie’s have also been translated into most languages.
Detective fiction is as popular today as it has ever been, probably because many novels have been adapted for television which introduced them to many people who do not usually read new detective crime fiction.
1. Which of the following is a detective story writer?A.Hercule Poirot | B.Perry Mason | C.Erle Stanley Gardener | D.Sergeant Cuff |
A.They have been long forgotten. | B.They have been translated into English. |
C.Nowadays they are the least popular readings. | D.They have been popular because of TV programmes. |
A.They all wrote stories about English detectives. | B.They all wrote stories about private detectives. |
C.They all wrote stories about police detectives. | D.They all wrote stories about American detectives. |
A.Wilkie Collins lived at the same time as Charles Dickens. |
B.Arson Lupin is a popular character on television nowadays. |
C.Private detective stories are better reviewed than police detective stories. |
D.A successful writer of detective stories has to write private detective stories. |
For a start, all the information in a story must be correct. Not only the spelling and grammar, but also the facts.
Any mistakes that appear in a story can get a newspaper into big trouble. For example, if a newspaper said that Yang Liwei was the first man to go into space, it would be wrong. He wasn’t the first. The newspaper would probably lose lots of readers because of that mistake.
A news story is not only correct,but also relevant to its readers . People are mostly interested in news that happens near to them. That is why you care more about what happens at your school than at American schools. It is also why newspapers in Beijing don’t talk about much news in Shanghai or Hong Kong.
Finally, news must always be fresh. When you pick up your evening newspaper, you want to read about news that happens that day. You don’t want to read about news from last week!
So, now you know what makes a good news story. Have a good look at our newspaper and see if it is full of good news. You can try writing a news story for our newspaper like a real reporter.
