While astronauts in space get to do many exciting things, they miss out on ordinary things that we will take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer.
About a year ago, NASA offered $125,000 to Anjan Contractor, a 3-D technology expert, to build a device 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 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 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 !

If you are travelling in Britain, besides so many world-class things to see and do in London, planning a day trip away from it can also be worthwhile.
Stonehenge
Stonehenge consists of a group of huge standing stones. The 5,000-year-old stones are one of the world’s biggest mysteries that no one has figured out yet. While exploring Stonehenge, you can imagine wildly and decide for yourself how the stones came to be there and why. Although you can’t touch the stones, you can walk among them and feel the changes of seasons.
Windsor
Most people visit Windsor to see Windsor Castle, where the Queen spends most of her time. The castle itself could keep you busy for days. The best way to appreciate Windsor Castle is to approach via the Long Walk, a straight road where there are no cars, but you might see some deer.
Oxford
Oxford is best known for its world-famous university. The large student population keeps the atmosphere young and fresh, though there’s no shortage of history if you want it. 30 colleges make up the university itself. A tour of the colleges is a must—Harry Potter fans will recognize various locations used in the movies.
Bath
Founded by the Romans, who used the area’s springs to create a spa retreat(水疗中心), Bath’s now the best tourist attraction of Southwest England. Visitors never miss the Roman Bath Complex, which is divided into four main parts—the Bath House, the Sacred Spring, the Roman Temple and the museum, which displays fascinating finds from the historical ruins of the city.
1.What remains a mystery about Stonehenge?
A. How long it has been there. B. Why the stones can’t be touched.
C. How the stones came there. D. Why it changes with seasons.

There are many things you can do to keep friendship strong forever.
Trust is very important in keeping any relationship strong and long lasting. If you trust the person whom you have a good relationship with and the other person also trust you in the same way, then you two have a good relationship.
You can remember important date of your friends such as their birthdays and wish them or give gifts to them on the special days. Many people say that money is the most important thing to consider, but remember friendship is not about money. You can find something small and inexpensive for their gifts or send online cards.
A friend should also always help others even when it is not very convenient. So have a helping hand ready at all times.
Sometimes distance makes relationships even closer. So, if you are far from your friends, there are many ways you can remain in contact(联系). You can use email, chat programs, and you can also write a blog and share your daily life activities with your friends.
If there is anything that makes you happy, share it with your friends. Listen to their thoughts as well. If they have achieved something noticeable, congratulate them and celebrate with them.
I have seen good friendships and when there is unhealthy competition between two friends. Though this may not happen in many cases, it is better to keep this idea in mind since it may happen to you.
As far as I have seen and experienced, it will be better not to either lend to or borrow money from your good friend. Of course, we have to do this with friends. But, attention should be paid so that your friendship may not end.
