Anvitha Vijay，who is only nine years old，has built two educational apps. One is Smartkins Animals，which helps many 【小题1】（child）identify more than 100 animals and 【小题2】 other is Rainbow Colors，which teaches kids colors.

With the help of YouTube videos，the young girl from Melbourne，Australia，learned codes（编码）at age 7 all by 【小题3】（she）. Soon，she was trying her hand at making apps.“When I first got my iPad，I 【小题4】（attract）immediately by all the apps on it，”she told TFK.“It wasn't long 【小题5】 I wanted to create my own.”

Anvitha's skills won her a scholarship to attend a big tech conference hosted by Apple in San Francisco，California. There，she got tips from the professionals and went to workshops 【小题6】 she learned about the latest software for app building. All that training led to an idea for a third app. This one，called GoalsHi，inspires kids 【小题7】（develop）good habits.

Anvitha's goal is to keep on 【小题8】 (create) technology that helps kids learn while they are having fun. But what's even more 【小题9】 (importance) to her is that the world sees the power of technology in kids' hands.“The more training we get in tech at an early age,”she says,“the 【小题10】 (good) chance we will have of becoming champions who will one day change the world.”

   A lot of people say math is not their strong suit. One New Jersey parent wants to help change that. Laura Overdeck grew up with numbers. She always helped measure ingredients（食材）when her mother baked，and she learned about angles from her father. She went on to major in astrophysics（天体物理学）in college. Overdeck wanted her own children to be good at math，too.“And when our first child was about two，we just started giving her a math problem every night，”Overdeck said. The problem was usually a story，involving animals，cars or candies that let the kid count.“Our third child started，at age two，yelling that he wanted his own math problem because he saw his brother and sister doing it. And we thought，‘Wow，we have a household where math is the popular thing at bedtime，’”Overdeck said.

In February，Overdeck set up Bedtime Math，an Internet website where she posts daily puzzles for children. Overdeck is particularly keen to hook（吸引）children on numbers before they go to school. So why introduce little ones to math so early？

Sian Beilock，an expert on performance anxiety，says the more fun and familiar math is early on，the less likely children will feel nervous when they start to learn math in school.“My lab has shown recently that kids as early as first grade report feeling anxious about doing math，”Beilock said.

“You can hear totally educated adults say，‘You know I’m just not that good at math.’or‘I’m kind of afraid of math.’And that’s a totally acceptable thing for a well-educated person to say，but you never hear them say，‘Well，you know，I’m just not that good at reading.’，”Overdeck said. She wants children and their parents to become as fluent in numbers as they are in Harry Potter.

   Robyn Lee， a 15-year-old teenage girl who studies at York Community High School， US says she has four friends. But she also has 15 to 20 other friends she considers part of her regular social circle.

“It's like a bad thing to have only one， friend ，”explained Robyn. “If you have one friend， it means only one person likes you. That’s not cool，” she said.

For many years， experts studying teen friendships have known that teenagers prefer to travel in groups. In studies conducted in 1963 and in 1995， researchers found teen friendship groups averaged six people. In 2005， when teens were asked about how many friends they kept in touch with regularly， the average answer was 20.

The change to bigger -group friendships has advantages， such as increasing more connections and improving teens' self-pride by giving them a place to belong.

However， the change also has some disadvantages，say psychologists. “The meaning of friendship is becoming much more complicated，” said Bernardo Carducci， a professor of psychology at Indiana University Southeast.

MaryRose Moss， a 17-year-old in Chicago， knows how she could get more friends. She created a Facebook page when she was 14 and within months ， she had her group of 500 friends.

Text messaging has opened the door to many new connections， she says. “I'm friends with some people that I wouldn't be as close to if it weren't for technology，” said Moss. “It's so easy to send a text to somebody even if you don't know him very well. ”

Some psychologists wonder whether social-networking technology is affecting some skills children once got from making friends in the old-fashioned way.

“In the past， you argued， discussed and reached an agreement， but if somebody disagrees with you now， you can ‘defriend’ him with the click of keys，” said Carducci.

Marianne Boe， a social studies teacher in Chicago ， sees signs of changing friendships in the hallways. Ten years ago， she could easily know groups of girls who stayed friends through all four years of high school. “Today， it's harder，” Boe said.

   With the development of modern science and technology，the functions of cellphones have changed greatly.【小题1】 The only difference may be that they fit in your pocket and you pay by the minute to use them.Some of the things a cellphone can do for you will be available this year：

Surf at speed

Cellphones that let you use the Web have been around for years.So，what’s new？ Well，faster thirdgeneration (3G) networks that let you surf at anywhere.【小题2】 Possible choices are from IJG Electronics VX 8000 and Motorola V1150.Listen as you go.

【小题3】 There is no doubt that it is about to change.Sony Ericsson’s new W8001 can hold around 150 songs in its 500 MB memory.And Samsung’s SPHV5400 even comes with a 1.5GB hard drive.Mobile phones may eventually replace mini MP3 players，especially for teens.

Camera cellphones are not new either but most of them have limitations： around 1­megapixel (百万像素).However new technology has made 2­megapixel units more common，and 3­megapixel units are showing up soon.Some 2­megapixel models，like Sony Ericsson’s K7501，offer limited zoom and focus controls.【小题4】 Portable TV.

You say you like “watching TV”？ That’s what Samsung MMA700 wants to give you.The new model lets users watch popular TV programmes for a fee.Other choices are Nokia’s 6620， Sanyo’s MM740 and NEC’s N940.【小题5】

The above are just a handful of what you’ll see in the coming months.Further down the road，your mobile phone may play a host of other roles，such as mobile credit card，position locator and so on.So what is there that a cellphone can’t do？
