About a year ago,NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert,to build a device(设备)that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype(原型)that begins by creating a single slice of dough(面团)that is cooked and printed at the same time.Then comes the tomato “sauce” — a mix of tomato powder,oil and water and finally,a protein slice that resembles cheese.While the video doesn’t show the baking process,the inventor says that once the pizza is printed,it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover,Anjan Contractor is far from ready for astronauts.That’s because he still has to find a solution to make the food container in the printer last for 30 years.Though that may sound unrealistic,actually it is not.
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients(配料)and then they are reduced to the powder form.This,as you can imagine,will not be so easy.But,while the printer may not be ready for space,it certainly looks ready enough for people on earth.Hopefully,NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

Somebody once said that knowledge is power, yet we constantly find from readers of our website that they have knowledge to burn and still do not have power. Just look at the academics in universities all around the world; they have so much knowledge that they should control the wealth of the world. In truth they work for peanuts and very few of them ever achieve the power of independence. So knowledge certainly isn’t power. Therefore, we should change that “wise” statement to: “Power is the ability to use knowledge to your own benefit.”
That paragraph was inserted because Annie is a typical academic—strong on talk and plans but a little weaker on actions. In the period of a twenty-minute conversation, she expounded(阐述)a whole list of plans and ideas to make the extra few hundred dollars each month she was seeking. Any one of her many ideas was a potential money maker, but she had taken action on none of them. At one time she said, “I’m lost as to what to do next.”
That was my cue(提示)to get involved. “Take action,” I advised.
All that is wrong is that Annie was inactive without knowing it. In five minutes we drew up a plan of action and agreed to talk again in a month to review progress. When we finished the conversation, she sounded much happier and more motivated than when we started. Annie just needs a little

After my very first visit to Cantata, my life changed forever. That may sound a bit dramatic, but volunteering with the elderly has changed my views on life.
Our visits last about an hour, and we bring 25-30 students every time. We play board games and cards with the residents while we’re there.
You can watch all the movies and TV shows you want about “life back then”, but nothing compares to talking to the people who were actually there. Just hearing their stories has touched me in a way I never thought possible.
Whether it was talking to 98-year-old “Hurricane Hilda” about her glory days as a roller skater or chatting with Lou about the times she danced with a famous actor, I was completely attracted by every single memory the residents wanted to share with me.
Even the residents who don’t have amazing memories make the experience satisfying . I remember visiting Mrs Robinson. She couldn’t recall much about her past, but she told me she’d never forget how kind I was just to listen to her “rambling (漫谈)”. It made me realize that it’s the little things that make life worth living. That’s something I won’t forget anytime soon.
If there’s one thing I’ve realized in my three years of visiting Cantata, it’s that presence – just being there – means more than anything to many of the residents. And despite how busy our lives are, there’s always time to make someone’s day.
For me, it feels great to be a source of happiness, a smile on a bad day or a listening ear for old memories. And at the end of the day, that’s all that matters.
It’s easy to feel like you don’t have anything in common with the elderly – especially when you’re a teenager. But that’s not true at all.
I hate to be overly clichéd (陈词滥调的) here, but age really is just a number. As young adults, it’s important for us to realize this sooner rather than later. We can learn a lot from the elderly, and they can often benefit from teenagers too.

5 . Christmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.
Middleburg, a small town in the state of Virginia, is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade(游行). Men and women ride horses through the woods and fields. They follow hunting dogs as they search for a wild fox. But first, these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats.
John Hale, a citizen of Middleburg says many city people visit his town. “We have a lot of people from an urban area that come to visit, but it incorporates a lot of the o1d traditions.” The nighttime hay ride is one such tradition. Small groups gather under the moonlight on an open wagon filled with hay. The passengers sing as farm horses pull the wagon slowly across the fields.
There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension.
“Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there’s really an opportunity where you’re allowed to step off for a little bit.”
Parade organizers say more than 13,000 people attend even in below-freezing weather. But if you ask, you will hear many different reasons why people come to watch the parade:
“I come here because I’m from a small town. I like how everybody comes together. ”“I live right down that street; right there. And that’s my dog.”
Middleburg looks its best at Christmastime. That may be why so many people return each year.
