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 2014 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.

    Once, when the food we ordered at a restaurant arrived, the first thing we wanted to do was to eat right away.{#blank#}1{#/blank#} Others want to take at least five photos of their food to share on social media, such as Wechat.

    {#blank#}2{#/blank#} “Foodtography” has been around for longer than one would expect. Take US photographer Irving Penn (1917-2009) for example. In 1947, Vogue magazine published many food photos taken by Penn. Looking at the carefully put salad ingredients or the cakes on stands(货 架), it would be easy to think Penn's 70-year-old photos were taken just last week.

    Besides Penn's efforts, it seems that social media is behind the recent rise of foodtography.

    {#blank#}3{#/blank#}And the star posts just one delicious-looking food picture with the place where it was taken. It can bring hundreds of new customers for the restaurant.

    So while it's fun to share pictures of delicious dishes with your friends, just remember the most important thing:{#blank#}4{#/blank#}

A. Don't forget to eat your meal afterwards.

B. But now, some people just want to eat their meal.

C. Today, a social media star may have thousands of fans.

D. In fact, taking pictures before meals is not a recent thing.

    Life is full of difficulties, from birth to death. When we face with problems, we often feel, "I am the only one having such problems." Or, we exaggerate (放大) our problems and regard them as most painful. But if we look around us, we will find other people may be in much worse conditions.

    Life is not always full of smiles and flowers. Every person has his own difficulties no matter who and where he is. So it's very important to have a correct attitude in your life. Only with the correct attitude can you face up all of your difficulties and finally overcome (战胜) them. First, you have to believe in yourself. That's the secret of success. Second don't blame others when you have difficulties, because it can neither help you avoid difficulties nor help you solve them. And the most important thing is that don't run away or give up. Use your ability to clear the difficulties that appear in your life. Third, remember how you overcome the difficulty because it may help you avoid similar trouble next time. Just take it easy, and enjoy the life even it's full of difficulties.
