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 !

1.NASA offered $125,000 to Anjan Contractor mainly to ____.

A. create some new type of 3-D printer

2.The biggest challenge that Anjan Contractor is faced with now is probably that ____

A. he has no money left to go on with his research

B. the pizza doesn't seem appetizing to pizza lovers

C. he has no way to make pizza that can last for thirty years

D. he cannot make the food container last for decades

3.What's the best title of the passage?

A. NASA is trying its best to help astronauts eat better

B. Astronauts may soon be able to enjoy steaming hot pizza

C. NASA is working on making pizza for common people

D. A 3-D pizza printer has been used to make pizza

Since people first launched rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spacecraft. But much of the space junk is made up of little pieces of things that were once bigger objects, until they struck each other and broke apart.

Some things we send into space fall back toward Earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.

But space junk falling on roofs is not the biggest worry. Scientists are concerned about the “Kessler” problem. Imagine what happens when an empty rocket strikes another while orbiting the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.

Marco Castronuovo, an Italian Space Agency researcher, says launching a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the Earth. After a time, the junk burns up in the atmosphere. Mr.Castronuovo has proposed using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite could jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.

Scientists have been concerned about space junk for many years. Right now, the costs of the clean?up have been too great. Mr.Castronuovo says his system could be put in place for a much more reasonable amount of money. So what can be done to clean up the space around our planet?

1.We can learn from the text that much of the space junk ________.

A. was left by the astronauts on purpose

3.It implies in the last but one paragraph that ________.

A. clearing up the space will actually cost little

B. small rockets also do harm to the atmosphere

C. only robots can clear up the space completely

D. it is still difficult for us to clear up the space

4.What is the text mainly about?

A. Space junk threatens earth's orbital environment.

B. Scientists use different methods to clear up space junk.

For more and more young Chinese professionals, the first day back at work after the Lunar New Year holiday is the day they quit.

The period after the Lunar New Year holiday, also known as Spring Festival, often sees Chinese workers on the move. This year, the number looking for new opportunities is supposed to be especially high.

Mr. Zhu, a 27-year-old Beijing native, is one of the young workers looking for a better deal. “Salary is a big concern for me and I need a job that pays more, and my department can’t provide good career development for me,” he said.

An online survey by Zhaopin.com, a leading job-hunting website, provides further details on why China’s young white-collar workers are so keen to move on.

Low salaries are the biggest concern for 62% of the job-hunters, and overtime and a wide mismatch between low salaries and high housing costs are also the complaints. Two-thirds of them said they had to work at home after office hours, and a full 95% said they felt they were under heavy pressure because of the housing payment or rent.

The survey also found that what was seen as a “good job” has changed. For the generation born in the 1970s, high salary and status is the key. For the generation born after 1980, work-life balance and respect in the office are also important.

Zhao Bin, a 28-year-old woman who earns over 7,000 yuan a month working at a public relations company in Shanghai, said she would wait until the Lunar New Year to change her job. “My salary is OK for me, but I am working like crazy. So I want to find something comfortable, like being an English teacher in training schools.”

1.Mr. Zhu is looking for a new job because ________.

A. he was fired before the Lunar New Year holiday

B. he was promised a better job

C. he wants a job better in salary and in development

D. he was advised to do so

A. a big gap B. a lost game

C. a hot debate D. a failed marriage

3.The writer uses the example of Zhao Bin to prove that ________.

A. salary is the first concern for people who change jobs

B. young people are under pressure of high housing prices

C. young people tend to value work-life balance

D. teacher has become a good job for Chinese youth

4.The article is intended to ________.

A. encourage Chinese white-collar workers to change jobs

B. present a social phenomenon and explain its causes

C. carry out an online survey to readers

D. compare different reasons why people quit jobs

If you are hungry, what will you do? Grab a piece of your favorite meal and stay quiet after that? Just like stomach, even your mind will be hungry. But it never lets you know, because you keep it busy thinking about your dream lover, favorite star and many such absurd things. So it silently begins to hide your needs and never lets itself grow. When mind loses its freedom to grow, creativity gets its full stop. This might be the reason why we all sometimes think “What happens next？”， “Why can't I think？”， “Why am I always given the difficult problems？” Well, this is the after?effect of using our brain for thinking of not?so?worthy things.

Hunger of the mind can be actually satisfied through extensive reading. But why is it reading but not watching TV? Because reading has been the most educational tool used by us right from the childhood. Just like that to develop other aspects of our life, we have to turn to reading for help. You have a number of books in the world which will answer all your “how?to” questions. Once you read a book, you just don't run your eyes through the lines, but your mind decodes (译解) it and explains it to you. The interesting part of the book is stored in your mind as a seed. Now this seed is unknowingly used by you in your future to develop new ideas. The same seed, if used many times, can help you link and relate a lot of things, which you would never think of in your wildest dreams！This is nothing but creativity. The more books you read, the wider your mind will become. Also this improves your oratorical (speech?making) skills to a large extent and also makes a significant contribution to your vocabulary. When you start speaking English or any other language fluently with your friends or other people, you never seem to run out of the right words at the right time.

Actually, I had a problem in speaking English fluently，but as I read, I could improve significantly. So guys, do join me and give food for your thoughts by reading, reading and more reading. Now what are you waiting for? Go, grab a book and let me know!
