It's March, 2050. 

Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times, but changed to electronic newspapers many years ago. 

There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the Us dollar has risen greatly in Shanghai, one of the world's leading business centres. Mary tells the computer to buy 5,000 dollars, and there is a quick response that it has been done. As they watch the screen, Mary orders one of the household robots to make coffee for them. Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television. Mary has a quick look at the shopping channels—the usual selection of electric cars, household robots and cheap travel offers-before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2023 they decided to move to the seaside and work from home. 

·Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home. Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer. According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades（十年）and then spend her time on music and painting.

How to deal with your homework

Write it down. Always be sure to write down all the homework so you won't forget anything.

Create a homework station. Find somewhere comfortable and quiet to do your home work. It will take twice as long to get the homework done. Shut off your cell phone, log off (退出) your computer (unless you need it for your homework) and close the door.

Do homework as early as possible. Don't leave homework to the last minute.The earlier you start your homework, the sooner you will finish! Do all your homework as early as you can, so you don't have a pile of (一堆) homework the next day.

 Think about how long it will take you to complete homework for each subject. For example: English-ten minutes, science-ten minutes, math-forty minutes, history-twenty minutes.

Treat yourself. You can easily get tired by sitting through an hour or two of homework without stopping. Once you finish homework for a subject, take a small break (no more than 15 minutes). Either taking a walk or finding something to eat will do. But do not turn on the TV, or you'll never go back to your study.

A. Use your time wisely.

B. Start as soon as you get home.

C. Start with your hardest homework.

D. Do not burn the midnight oil, either.

E. Never do your homework in front of the TV.

F. After short breaks, return to finish the rest of your homework.

G. Keep a homework notebook where you record all your homework.

The first time I heard about my classmates engaging with social media was in the fourth grade. A lot of my friends and classmates had excitedly jumped onto platforms like Instagram at such a young age. On the other hand, I hesitated. I only knew the basics, but was foreign to some words on social media.

All throughout middle school, I stuck with the same thinking. And now, as a freshman in college, I am looking back and wondering why I, unlike my classmates, have never been naturally interested in social media.

Scanning Instagram, you ought to find dozens of pictures of people in beautiful countries, taking part in exciting activities, and spending time with friends and family, among many other things. The thought of doing this has never related to me. I respect and understand those who do believe using social media allows them to express themselves and share aspects of their lives with others. However, I have never had any interest in doing the same. In my eyes, when not shared with others, family gatherings and friend get-togethers are just as meaningful, if not more so.

Most people have experienced feeling insecure (不安全) and unconfident on social media. Images that are changed represent unrealistic beauty standards that can only be obtained through dangerous ways. Even without using social media, I knew that using apps like Instagram and Facebook would make me embarrassed about all the aspects that make me a unique individual. I've never wanted to look at a post on social media and immediately compare myself and my life.

I constantly observe my classmates getting easily distracted (使分心) by social media. While trying to complete their homework, they have a powerful urge to open up Instagram or Facebook to see if there are any new messages. With homework and after-class activities consuming the majority of my day, I cannot wait to finish every task on my to-do list, so I can finally spend time with my family or have some time for myself to relax from my busy day.

The sun is setting, brightening your kids' faces as they play in the waves. You reach for your phone for this perfect moment. But before you do, here's a bit of surprising science: Taking photos is not the perfect way to keep memory as you think.

Taking too many pictures could actually harm the brain's ability to keep memories, says Elizabeth Loftus, a psychology professor at the University of California, Irvine. So we get the photo but kind of lose the memory.

Photos may outsource memories. It works in two ways: We either shake off the responsibility of remembering moments when taking pictures, or we're so distracted (分心的) by the process that we miss the moment altogether.

The first explanation is the loss of memory. People know that their camera is recording that moment, so they don't try to remember. Similarly, if you write down someone's phone number, you're less likely to remember it offhand because your brain tells you there's just no need. That's all well and good — until that piece of paper goes missing.

The other is distraction. We're distracted by the process of taking a photo — how we hold our phone, composing the photo, such as smiling faces, the background to our liking and clear image, all of which uses up our attention that could otherwise help us memorize.

However, taking photos can benefit memory — when done mindfully. While taking a photo may be distracting, the act of preparation by focusing on visual details around has some upsides.

When people take the time to zoom in (拉近镜头) on specific things, memories become strengthened.

Another benefit is that we recall moments more accurately with the photos. Memory has been reshaped with the help of new information and new experiences. Thus, photos or videos help us recall moments as if they really happened.

Memories die away without a visual record backing them up. Therefore, a photo is an excellent tool to help remember when done purposefully, which is worth exploring further.
