Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned．Sites such as Facebook, Twitter and Bebo are said to shorten attention spans （幅度）, encourage instant satisfaction and make children more self-centered．
Warnings from neuroscientist （神经系统科学家） Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day．But they will strike a chord （弦） with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens．
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts．A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves．But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good．
Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain．Computer games and fast-paced TV shows were also a factor, she said．"My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment．" "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said．
Psychologists have also argued that digital technology is changing the way we think．They point out that students no longer need to plan their term papers before starting to write—thanks to word processors they can edit as they go along．
A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen．Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven．Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning．
Sue Palmer, author of Toxic Childhood, said: "We are seeing children's brain development damaged because they don't engage in the activity they have engaged in for thousands of years．I'm not against technology and computers．But before they start social networking, they need to learn to make real relationships with people．"

According to the passage, social networking websites might _____．

You may not realize it, but you are doing more than just studying when you are at school. The school is also the place where you learn__________. But this is not always easy. What can you do if you just don’t like one of your classmates?

If you discover that you have problems getting along with your classmates or friends, the most important thing to learn is tolerance. Tolerance is the ability to realize and respect the differences in others.We can not change the way that other people do, so it is important to learn to live happily with them.

Tolerance will make everyone get on better with each other. Knowing others constantly makes us  understand others’differences. Something different does not exactly mean that it is bad. Tolerance teaches us to keep an even temper and an open mind.

You need to remember an old saying, “Treat others how you want to be treated.” You would like to be treated kindly by your classmates, so it is important to treat them kindly too. If you tolerate something, it does not mean that you have to like it. No one is asking you to change who you are or what you believe in.Tolerance just means that you should respect the differences in others and not try to make them change.

It is important to practice tolerance, because it will make everyone’s life easier. Learn to accept people for their different abilities and interests. The world is very different, and practicing tolerance in your own school and city can help make a difference.

Jenny was almost five. Waiting with her mother at the checkout stand, she saw a circle of white pearls（珍珠） in a box. “Oh please, Mommy .Can I have them? Please, mommy, please!”
Quickly the mother checked the back of the little box and said ,” That’s almost $2.00. If you really like them, I’ll think of some extra chores for you and in no time you can save enough money to buy them for yourself.”
Then Jenny began doing more chores at home and did housework for neighbors. On her birthday, Grandma gave her another new dollar bill and she had enough money to buy the necklace.
Jenny loved her pearls. She wore them everywhere, even to bed.
Jenny had a very loving daddy and every night when she was ready for bed, he would stop whatever he was doing and come upstairs to read her a story. One night when he finished the story, he asked Jenny, “Do you love me?”
“Oh yes, Daddy. You know that I love you.”
“Then give me your pearls.”
“Oh, Daddy, not my pearls. But you can have my Princess.”
“That’s okay, Honey. Daddy loves you. Good night. ”And he brushed her cheek with a kiss.  
About a week later, after the story time, Jenny’s daddy asked for the pearls again. And Jenny refused him again.
A few nights later when her daddy came in, Jenny was sitting on her bed with her legs crossed. As he came close, he noticed one silent tear rolling down her cheek.
“What is it, Jenny? What’s the matter?”
Jenny didn’t say anything but lifted her little hand up to her daddy. And when she opened it, there was her little necklace. She finally said, “Here, Daddy. It’s for you.”
With tears gathering in his own eyes, Jenny’s kind daddy reached out with one hand to take the dime-store necklace, and with the other hand to reach into his pocket and pull out a blue case with real pearls and gave them to Jenny. He had had them all the time. He was just waiting for her to give up the dime-store stuff so he could give her the real treasure.
