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.

   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.

Hi! Welcome to my webpage. My name’s Tom Wood and I’m an English teacher. I【小题1】 (design) this webpage last week so that my students can learn more about me. I think it is important 【小题2】 (know) my students well. And it is fair 【小题3】 my students know me well, too.

I was born in London, England, but I’ve lived and worked in China for the past 15 years and I really like living here.

I can speak Putonghua and even a little bit of Cantonese, 【小题4】 is my wife’s dialect (方言). I practice 【小题5】 (speak) Chinese every day and my Chinese is improving. 【小题6】 (fortunate ) , there are many people in my town who are ready to help me with my Chinese! I particularly enjoy talking to my neighbors.

My favourite sport is football. I play football once a week with some of the other teachers at the school. We’re going to organize a 【小题7】 (compete) with teams of teachers from other schools this summer.

My other great love is my motorbike. I love getting on my motorbike and riding out to the countryside. But my wife thinks it’s too 【小题8】 (noise) and dangerous. If anyone wants to send me an email, just 【小题9】 (do) as you like. I’d love to hear 【小题10】 you.

   Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules（分子）.

Intelligence Advanced Research Projects Activity（IARPA）announced plans to develop tabletop-sized machines that can store and retrieve（取回）data from large batches of polymers — a term that refers to a wide variety of long，string-like molecules. Polymers can store data in individual atoms or groups of atoms.

The project is an attempt to solve a basic problem of the modern era:the vast and growing costs of data storage. Datacenters around the world sucked up 416. 2 terawatt hours of electricity in 2016. That's about 3 percent of the global supply，and it accounts for 2 percent of global greenhouse gas emissions.

A 2016 paper found that DNA，in particular，could store computer information more densely，require less energy，and survive higher and lower temperatures than conventional hard drives. The authors of that paper reported on the successes of prototype（雏形）DNA computers that used the genetic molecules for both long-term storage and random access memory（RAM）.

But no one has yet figured out how to handle DNA data storage on large scales.

IARPA officials said the new effort, called Molecular Information Storage, will be broken up into three periods:a two-year program to figure out how to store data in DNA or other molecules at high speed,a two-year program to figure out how to retrieve that data at high speed, and a two-year effort to develop an operating system that can run on that DNA.

Many of the technologies IARPA wants to develop are untested at these scales, so it's unclear how far away that proposed tabletop device really is.

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.
