“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.

     For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.

     One of the oddest effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive(认识的)abilities. “I’m pretty sure there is no effect on short-term memory,” he says.

     Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神经元突触) exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.

An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.

“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid.

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.
