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.

When we talk about a bad man, we like to call him a “wolf”. But is it really true that the wolf stands for devil and ugliness？
Have you read the book “The Wolf Totem” by a famous writer Jiang Rong, which tells the story of the relationship between wolves and human beings? Have you ever 41 the wolves' world? If you had, you would 42 the wolves. In the book, wolves are heroes on the large grassland. They know more about 43 than humans. They can attack lambs without disturbing their mothers. They also know how to 44 full use of the shape of land to 45 sheep. I believe that if wolves were humans, they would be 46 experts good at fighting.
The wolf is a kind of special creature that can deeply understand 47 .Each wolf serves its group with its heart and soul. A 48 wolf has little power, but a pack of wolves 49 nothing. All the wolves obey the rules. 50 they are defeated, they run away together. It is their teamwork 51 makes wolves powerful.
The wolves also have great self respect and won't 52 to anyone. The writer, who wrote the book “The Wolf Totem”, 53 stole a one-month-old baby wolf and raised it very carefully. To his 54 , he found the little wolf still wanted to go back with 55 wolves. He bit through the iron chain that limited him. The wolf was 56 and he never gave in, fighting 57 his death. The little wolf died as a glorious fighter.
I was shocked by this kind of 58 wolves are one of the most respected creatures on the earth. I want everyone to look at wolves in a 59 way. They are our teachers. They show us how to survive and 60 in this not simple but dangerous world. Please honor the wolves, please honor all these heroes of nature!

It was one of those cold winter nights in the Haight-Ashbury district of San Francisco . I was driving an eyesore（丑陋的东西）that could only be 36 as a “ car ” by someone who was either a shameless liar or a good friend .
It was 37 to drive the car because you had to keep your fingers and toes crossed to keep the engine running . I tried to imagine I was driving a huge clumsy 38 ; that way I didn’t 39 the slow speed .
That night I must have uncrossed my fingers to scratch something . The car 40 in the middle of a four-lane stretch of Oak Street . I 41 for a place to turn off（拐弯）, but the street was lined with parked cars .
There I sat , in 42 traffic , as tons of vehicles screamed by . In my rearview mirror（后视镜）I saw a car 43 behind me . I knew what was coming . Soon the horn would start and someone would be 44 at me . But I was 45 .
A stranger got out of the car and came to my 46 . He asked , “ Do you want a 47 ?”
I was surprised but 48 . And then he 49 to his car and two teens piled out to help push my car . When I was 50 delivered to a side street , they got back into their car and rejoined the sea of 51 . I didn’t get to 52 them .
Over the years I’ve realized something about the 53 who stopped to help . I’ve noticed that every time I’m in 54 , he appears . The one true thing in this world is an unasked 55 provided by a stranger .

I am sure many people have said about me, “He must be the happiest man in the world!” But they were wrong.36 I was famous and had 37 money, I was not really happy. I found myself asking, “ 38 does all this not give me real happiness?”
Newspapers said, “Kriss Akabusi is the European champion. He has also39 an Olympic bronze medal.” Now before all this happened, I had40 , “If I can become a champion, I will be happy. I will41 a lot of money and then enjoy42 . I will have a good time.”
When I went to the Edinburgh Games, in my hotel43 I found a book by my bedside. It was called What’s Real Happiness in Life? I44 this book up and read some of the stories in it. The book mainly told about the happiness brought by helping others. But I said to45 , “All these things are too46 for me to do.”
But that night I had a47 . I found myself standing by a river. I48 a voice calling to me from the other side of the river. The voice said, “You know helping others is as49 as crossing the river, and it’s not as difficult as you imagine.” Then suddenly I awoke. I realized I was50 now when compared to before. I found I had real51 of mind.
So I can now tell my friends what I have52 . Being famous and having a lot of money53 gave me happiness. So all I can say to you is this—we are54 when we think that to be famous and rich will make us happy. Now I have a children’s TV program called Record Breakers. I have no55 about what tomorrow will bring.
