One of my earliest memories was watching my mom talk on our old phone. I was fascinated that she could talk to someone who wasn't actually in the room with her. 【小题1】 I was wondering how she managed to talk with someone she couldn't see.

That was a long time ago. Later, we had mobile phones that could be carried around the room. 【小题2】 These days I can send an e-mail around the world in a second. My daughter's smart phone has a hundred apps and a dozen social media accounts. She stores all of her information in a mysterious place known as“the cloud disk”, where she can take it out at any time. It seems that we are more connected in this world than ever before.

【小题3】 Few spend time talking face to face. Instead of looking into the eyes of our loved ones , we store their photos at our screens. It seems that the most connected generations are also the loneliest.

Don't let technology take our time and ruin our life. Make the time to communicate with each other. Take a walk on the beach with a friend. Have a long conversation with the phones off and the hearts on. 【小题4】

Remember that we are here to love each other,help each other and make this world a better place. 【小题5】 But when it can't, turn it off.

   Smartphones have been blamed for everything from taking drivers’attention from driving to keeping people on the sofa scrolling (滚屏) videos. But the smartphone that seems to be everywhere could just easily increase physical activity if it pushes its owner’s buttons in the right way.

New research shows that making social connections (人际关系) through activity-tracking apps gets people to move more. And another study on the “Pokemon Go” phenomenon shows that the smartphone game got players to take thousands more steps than usual. Together, the studies show the potential (潜在性) of smartphones to push a range of people to be more active.

People who linked with friends on the activity-tracking app increase their steps by 400 a day on average, compared with people who made no social connections, according to Tim Althoff and two other computer scientists at Stanford University. Such opinions show the possibilities of smartphones and games to help with one of the most stubborn public health problems — that even people who want to be active have trouble staying active.

An NBA video game, for example, will give players extra powers in the game if they reach a step goal in real life. The app “Zomies, Run!” uses audio stories to push people to run more or run faster.

Still, there is room for growth: Only about 4% of all health apps use “gamification”, such as point- scoring or competition, according to a study published in October in BMJ Open. “Gamification is actually quite closely linked with behavior change techniques,” says Dr. Elizabeth Ann Edwards, the study’s lead author.

   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.

Nowadays，there is a growing 【小题1】 (popular) of Internet surfing on college campus. 【小题2】 increasing number of students，【小题3】 (major) in science，engineering or liberal arts，spend many hours surfing the Internet with keen interest every day.

So far Internet surfing 【小题4】 (attract) college students like magnets（磁铁）for the reason 【小题5】 it is the world of Internet and the world of globalization. First，【小题6】 the global coverage of Internet，we can reach out to and touch anyone at any place of the world. Via Internet, we can send and receive e-mails at any time much faster, cheaper and more effective than 【小题7】 (tradition) means such as telephone, telex and fax. Next, access to the home pages makes it easy 【小题8】 (get) all kinds of information. Finally, by clicking the mouse, we are able to do such important things as shopping, finding jobs, making friends, and downloading files. What's more, Internet offers many chances.

In the Information Age, 【小题9】 is difficult to imagine modern life without Internet. With information technology industry developing 【小题10】 (rapid), successful dot-com companies appeared everywhere. Internet is revolutionizing our economy, our society and our life.

   Online shopping has become very popular in recent years. It’s a brand new way for shopping, and at the same time, it saves money because items sold online are much cheaper. Therefore, customers from different countries are changing their ways of shopping. As for some wise men, they find another way to save much more money-using online coupons（优惠券）to shop. Online coupons enable them to get the items they want to buy much cheaper.

As we all know, sometimes manufacturers, shops, restaurants and entertainment clubs will provide special offers. For example, a shirt asks for $100, but if a coupon is used, the customers may get the shirt at $90. Sometimes, by using a coupon, one can luckily get a free product. Online coupons work in the same way; online shoppers get discounts by using online coupons.

In this case, you are advised to do some research to make sure whether there is a coupon or vouchers（代币券）concerned with the items you want to buy online. Then comes the point where to find online coupons. Usually there are three ways:

1. Find the official websites of the brands. To promote sales, some brands will offer online coupons on their own websites.

2. Visit the special coupon websites. There are special websites where coupons from many shops, restaurants and so on are gathered. Buyers input（输入）keys of coupons they are fond of, and thousands of related coupons in different cities in America will be listed. To narrow down your list, just click the district you are located in.

3. Pay attention to some social websites. To let more people know coupon information, some shops will show their information on social websites where a lot of online buyers visit.

Because information on the Internet often cannot be cleaned in time, much invalid information will be searched out. So when you find a proper coupon, please don’t get carried away. Read the information carefully, ensuring that they have not expired（失效）yet. If interested, you can visit Couponeed. com to find coupons and save money.
