The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.

         The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock  trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.

 38 __, a new study published in Current Directions in Psychological Science warns that there are 39___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason.  40  _, we are not 3 meters tall  41 _ most people’s hearts are not strong enough to send  42 _  up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __43  , such as the size of the mother’s pelvis (骨盆).

Does your child struggle in school? Is he or she afraid of reading out loud, writing an essay, or working out a math problem? While every kid has trouble with homework from time to time, if a certain area of learning keeps going wrong, it might show a learning disorder. Learning disorders, or learning disabilities, are a general term for a wide variety of learning problems.

A learning disability is not a problem with IQ or motivation (动机). Kids with learning disabilities aren’t lazy or slow. In fact, most are just as smart as everyone else. Their brains are just wired (装电线) differently. Simply put, children and adults with learning disabilities see, hear, and understand things differently. This difference affects how they receive and process (处理) information. This can lead to trouble in learning new information and skills, and putting them to use.

It can be tough to face the possibility that your child has a learning disorder. No parents want to see their children suffer. You may wonder what it could mean for your child’s future, or worry about how your kid will make it through school. But the important thing to remember is that most kids with learning disabilities are just as smart as everyone else. They just need to be taught in ways that suit their unique learning styles.

It’s not always easy to tell whether a child has learning disabilities, for learning disabilities look very different from one child to another. One child may struggle with reading and spelling, while another loves books but can’t understand math. Still another child may have difficulty understanding what others are saying or communicating loud. However, some warning signs are more common than others at different ages. If you’re aware of what they are, you’ll be able to catch a learning disorder early and quickly and take steps to help your child as quickly as possible.

The ability to memorize things seems to be a vanishing （消失的） technique．So what can we do to bring out brain cells back into action? A newly published book on memory, Moomvalking with Einstein: The Art and Science of Remembering Everything, by American journalist Joshua Foer, makes a telling point, one that is an analysis of the importance of memorising events and stories in human history; the decline of its role in modem life; and the techniques that we need to adopt to restore the art of remembering．

As For points out, we no longer need to remember telephone numbers．Our mobile phones do that for us．We don't recall addresses either．We send emails from computers that store electronic addresses．Nor do we bother to remember multiplication tables （乘法表） ．Pocket calculators do the job of multiplying quite nicely．Museums, photographs, the digital media and books also act as storehouses for memories that once we had to keep in mind．

As a result, we no longer remember long poems or folk stories by heart, feats （技艺） of memory that were once the cornerstones of most people's lives．Indeed, society has changed so much that we no longer know what techniques we should employ to remember such lengthy works．We are, quite simply, forgetting how to remember．

And let's face it, there is nothing sadder than someone who has lost their mobile phone and who finds they cannot even phone home or call their parents or partners because they cannot remember a single telephone number．That is a sad example of loss of personal independence．So, yes, there is a need for us to he able to remember certain things in life．

Therefore, Foer's book outlines the methods that need to be mastered in order to promote our memories and regain the ability to recall long strings of names, numbers or faces．In the process, he adds, we will become more aware of the world about us．

The trick, Foer says, is to adopt a process known as " elaborative encoding", which involves transforming information, such as a shopping list, into a series of "absorbing visual images"．If you want to remember a list of household objects—potatoes, cottage cheese, sugar and other items, then visualise them in an unforgettable manner, he says．Start by creating an image of a large jar of potatoes standing in the garden．Next to it, imagine a giant tub of cottage cheese—the size of an outdoor pool—and then picture Lady Gaga swimming in it．And so on．Each image should be as fantastic and memorable as possible．

Using methods like this, it becomes possible to achieve great feats of memory quite easily, Foer says．It certainly seems to have worked for him: he won the annual US Memory Championships after learning how to memorize 120 random digits in five minutes; the first and last names of 156 strangers in 15 minutes; and a deck of cards in under two minutes．"What I had really trained my brain to do, as much as to memorise, was to be more mindful and to pay attention to the world around," he says．

These techniques employed by Foer to master his memory were developed by Ed Cooke—a British writer and a world memory championship grandmaster．He acted as Foer's trainer during preparations for the book and helped him achieve his championship performances．" Memory techniques do just one thing: they make information more meaningful to the mind, making the things we try to learn unforgettably bright and amusing," said Cooke．

       Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast．Diagnosed with diabetes（糖尿病）, Thomas would need to inject himself with insulin（胰岛素） three times a day for the rest of his life or risk nerve damage, blindness, and even death．And if that weren't bad enough, he had no health insurance．

       After a month of feeling upset, Thomas decided he'd better find a way to fight back．He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics and their loved ones — a place where over 1,100 people share personal stories, information, and resources．

       Jason Swencki’s son, Kody, was diagnosed with type diabetes at six．Father and son visit the online children's forums（论坛） together most evenings．"Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. “They know what he's going through, so he doesn't feel alone.”

       Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases．And more people are being diagnosed at younger ages．

These days, Thomas's main focus is his charity, Fight It, which provides medicines and supplies to people — 225 to date — who can't afford a diabetic's huge expenses．Fight-it．org has raised about $23,000 — in products and in cash．In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean．

Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables．"Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. “But Christopher is the only person I know saying people need help now.”
