1 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.
In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.
In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.
Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.
Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?

2 . As a child I was one of the 125 people at our family gathering for New Year. These days we were a much smaller group in Belle Valley, Ohio. I insisted (坚持要求的) on acting as hostess and wanted to bring back the joy I’d felt at my childhood New Year that filled with love.
As family members arrived at the hall, I handed each one of them a numbered card and said, “Time for the alphabet game.” “What kind of game is that?” one of my great-grandchildren asked. “well,” I said, “who’s got number one?” A cousin raised her hand. “Tell us something you never forget,” I said. “Something that begins with the letter A.” My cousin smiled. “Apple pie!” she said. Great-granddaughter Mindy was next. “B,” she said. “I am impressed by Buckeye Country.” “Cookies!” Number 3 shouted.
Until Number 17, “The next one’s a challenge,” I said. “Who’s got 17?” Ryan, my son, slowly raised his hand. “Q,” he said. “Quaker City Carnival (嘉年华).” The room went silent.
“It’s one of the oldest traditions in Ohio,” Ryan said. “Grandma and Grandpa met there. That’s where they fell in love. That’s where this whole thing started. This whole family.” Ryan looked around the room, making eye contact with everyone. “We wouldn’t be here celebrating New Year together if it wasn’t for Quaker City Carnival.”
The room burst into laughter and was full of the love that had kept us connected to our Ohio traditions. “This is the best New Year we’ve ever had,” a great-grandson said to me secretly. Whatever their New Year would look like when they grew up, they’d remember this one. And for me, I had an unforgettable New Year to treasure — a memory where love started with the letter Q.

3 . Your options for an ego - friendly home may seem somewhat limited now—solar panels, rain barrels, and maybe a small garden—but as the world of green technology advanced, there is a rise in the number of smart, ego-friendly home improvements. Some of them are available now.
A home thermos tat (恒温器) can automatically adjust the temperature for you, making sure your house is warm when you get home and reducing energy waste during the day. For example, a thermos tat called Nest Learning Thermos tat learns your heating and cooling preference and automatically adjusts itself.
Years ago, recycling paper and plastic was the most you could do to save resource.
In 2009, The Wall Street Journal asked four architectural firms to imagine the future of green homes.
| A．There are quite a lot of benefits of green homes. |
| B．Others, like walls made of gardens, are a bit more futuristic |
| C．Traditional energy sources are still the norm in most houses |
| D．Nest users have saved 29 million in energy in less than two years |
| E．It will depend on the type of heating and cooling system in your home |
| F．Now, recycling factories have gone way beyond the traditional materials |
| G．And one of the groups, Rios Clementi Hale Studios, undertook the project |
4 . Is there anybody out there? For centuries humans have wondered although the ways in which we have gone about this have varied. As we have gained a greater understanding of the universe, our searches have taken on more concrete(具体的) forms. Questions about aliens(外星人) have become a subject for science rather than science fiction.
Now new cooperation between the Very Large Array (VLA) observatory in New Mexico and the SETI Institute in California means that our curiosity about whether aliens exist can be closer than ever before to being satisfied. Data from the VLA’S 28 radio telescopes, used to scan a vast area of sky, will be fed through a special supercomputer that will search for distant signals.
How likely it is that a signal will be found, and what this might mean, are hard questions to answer. SETI’s existing projects have not discovered any signals from other planets so far. But recent discoveries in space and Earth sciences have provided some encouragement for those who are enthusiastic about the possibility, however remote, of detecting other civilizations.
Once it was thought that our solar system could be unique. Since the discovery of the first exoplanet (a planet beyond the solar system) in the 1990s, thousands more have been located. Around one in five stars is now thought to have a planet in their orbit(运行轨道) in a so-called “habitable(适合居住的) zone”—that is, at a distance from the star where the temperature means that life is theoretically possible.
Are Earth’s 7.5 billion humans, along with billions of other animals and plants they share their home with, on their own in the universe? If there is another life form somewhere, could it be as intelligent as humans? Or could it threaten them? I think all of these need further exploration. As explorations of Mars continue, and a new set of observations from the James Webb Space Telescope are set to begin, our interest in the possibility of alien life appears as much as before.

| C．Receiving signals: aliens appear again? | D．Exoplanets: home of aliens |
5 . In the Hollywood movie The Martian, actor Matt Damon plays an astronaut who grows food on Mars(火星)to survive alone on the red planet.
After seeing the movie, Washington State University physicist Michael Allen and University of Idaho food scientist Helen Joyner decided to carry out a case study helping students figure out how to farm on Mars. In the case study, students have to imagine they are mining(采矿) on Mars and decide how to feed themselves there before starting on the journey. They get advice from Allen and Joyner on how to select crops and take the challenges of growing crops over long periods on Mars. Students use a scoring system to select three foods to plant on Mars.
Allen found the results impressive: among 30 students, “no two people have ever gotten the same answer”, he said.
Human travelers to Mars will likely have to make use of resources on the planet rather than take everything they need with them on a spaceship. This means farming their own food on another planet, one that has a very different ecosystem (生态系统) from Earth’s.
One challenge for those who would like to live on Mars is the fact that there can be no farming tools. Like real astronauts, students taking part in the study cannot take a lot of farming tools with them. As Joyner put it to his student astronauts, “You are starting with nothing.”
Besides, students also have to deal with a very limited choice of diet. “If I had to eat a single food for the rest of my life, could I do it?” Joyner asked.
But Allen believes the case study is about more than farming and eating on the Red Planet.
“I’m not teaching about growing food on Mars,” Allen said. “I’m teaching about living with choices. I’m teaching about problem solving.”
