With time flying, people become aged. Then many people even in their middle age often start to notice that their memory and mental clarity are not what they used to be. We suddenly can’t remember we put the keys just a moment ago, or an old friend’s name, or the name of an old band we used to love. As the brain , we refer to these occurrences as "senior moments". seemingly innocent, this loss of mental focus can potentially have a(n) effect on our social and well-being.
Neuroscientists,experts who study the nervous system, are increasingly showing that there’s actually a lot that can be done. It out that the brain needs exercise in much the same way our muscles do, and the right mental can significantly improve our basic cognitive(认知) . Thinking is basically a of making connections in the brain. To a certain extent, our ability to in making the connections that drive intelligence is inherited(继承). , because these connections are made through effort and practice, scientists believe that intelligence can expand and wave mental effort.
Now, a new Web-based company has taken a step and developed the first "brain training program" designed to actually help people improve and their mental sharpness.
The Web-based program you to systematically improve your memory and attention skills. The program keeps a(n) of your progress and provides detailed feedback(反馈) your performance and improvement. Most importantly, it changes and improves the games you play to up the strengths you are developing-much like a(n) exercise routine which requires you to increase resistance and vary your muscle use.

positive through the cold season could be your best against getting ill, new study findings suggest.
In an experiment that healthy volunteers to a cold or flu virus, researchers found that people with a sunny characteristic were less likely to ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help the common cold and other illnesses.
Researchers believe the reasons may be both objective as in happiness increasing immune(免疫的) function and subjective as in happy people being less by a scratchy throat or runny nose. “People with a positive emotional style may have different immune to the virus,” explained the lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. “And when they do get a cold, they may their illness as being less severe.”
Cohen and his colleagues had found in a study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional tendency itself had the effect.
For the new study, the researchers had 193 healthy adults with complete standard measures of personality tendency, health-consciousness and emotional “style”. Those who be happy, energetic and easy-going were judged as having a positive emotional style, those who were often unhappy, tense and unfriendly had a negative style. The researchers gave them drops through their noses either a cold virus or a particular flu virus. Over the next six days, the reported on any aches, pains, sneezing they had, while the researchers collected data, like daily mucus(黏液) production. Cohen and his colleagues found that based on objective measures of nasal woes(鼻部的不适), happy people were less likely to develop a cold.

One day, Ryan asked me to hold the torch (火炬) runner's flag that would 41 the spot where Ryan would 42 his Olympic torch run. He gently explained that he would be honored 43 I would accept this position for him. The Olympic committee sent a letter saying that the person that holds the flag for him must be someone 44 to him. He said I was the only true friend he had 45 made that talked to HIM and not to his wheel chair. How could I 46 such a request?
On the morning of June 5th, as I walked down the sidewalk, my heart 47 and my mind became a factory of questions. I kept wondering how everything was going to happen and how Ryan would 48 the huge crowd of thousands of people.
After the van arrived, the other runners got out and lined up outside the van, chanting his name, "Ryan! Ryan!" Then all of the people 49 in, “Ryan! Ryan!” The lift then lowered Ryan to the ground. There he was, in all his 50 .
It all became slow motion at the sight of the arriving torch. The runner lit Ryan's torch and then Ryan began his 51 . As he took off down the street, the chanting became louder and louder. The 52 filled the air and even I felt like I was on cloud number nine. I could not have been any prouder of Ryan！ He 53 this moment in time --a historic moment--a moment that he was a part of and 54 me to be a part of, too.
Mr. Weinheimer, the next torch runner, bent over and gave Ryan a hug. That moment will last in time forever. It symbolized the whole 55 of the flame: love, excitement, enthusiasm, brotherhood, and life of any man. The flame united us all and showed that love is really what makes this small world go around after all.
