A
There's no pizza on Mars，but scientists have found a way to solve this problem for hungry astronauts：a pizza printer！NASA has developed a machine that “prints” food.They showed a model of the printer in Texas，US.21·世纪*教育网
How does it work？Cartridges(墨盒) can be filled with powdered dough(弄成粉末的生面团)，cheese，sauce，water and oil.Put these ingredients onto a printer bed.The printer bed，which gets hot from below，cooks the food as it's being printed.【来源：21cnj*y.co*m】
Most of the ingredients are powdered，so they can be sent into space and stored(贮存) for many years without going bad.The food powder can mix with water and oil when they're being printed.21*cnjy*com
In outer space，there are fewer choices for astronauts for dinner.Most of their foods－even things like beef－are eaten from bags as powder.Scientists hope the new food printer can be used to make more delicious food in outer space，keeping astronauts healthier and healthier.
The printer isn't only used in outer space.Scientists think it could be useful on the earth，too.People can make meals at the dinner table according to their different needs.
(A)16.What is the main idea of the second paragraph?
A．How the printer works.
B．The advantages of the printer.
C．How the printer was invented.
D．How food in outer space is stored.
(B)17.Which of the following is TRUE according to the passage?
A．A model of the food printer was shown in New York.
B．Astronauts can eat beef powder in outer space.
C．The food will be cooked after being printed.
D．The printer can only be used in outer space.
(A)18.Which is the best title for this passage?
A．Hungry？Just Print!
B．How to Make Pizza
C．How to Make a Printer
D．Astronauts' Life in Outer Space
B
Do you want to live another 100 years or more？Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.21·cn·jy·com
“I think we__are__knocking__at__the__door__of__immortality__(永生) ，”said Michael Zey，a Montclair State University business professor and author of two books on the future.“I think by 2075 we will see it and that's a conservative estimate (保守的估计)．”
At the conference in San Francisco，Donald Louria，a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will live in the future beyond what has been possible in the past.“There is a great push so that people can live from 120 to 180 years，”he said.“Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However，many scientists who study in ageing are doubtful about it and say the human body is just not designed to last past about 120 years.Even with healthier lifestyles and less disease，they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live.“It remains to be seen if you pass 120，you know；could you be healthy enough to have good quality of life？”said Leonard Pooh，director of the University of Georgia Gerontology Centre.“At present people who could get to that point are not in good health at all.”
(B)19.By saying “we are knocking at the door of immortality”，Michael Zey means ________.
A．they believe that there is no limit of living
B．they have got some ideas about living forever
C．they are sure to find the truth about long living
D．they are able to make people live past the present life span
(C)20.Donald Louria's attitude towards long living is that ________.
A．people can only live from 120 to 180
B．it is still doubtful how long humans can live
C．it is possible for humans to live longer in the future
D．the human body is designed to last past about 120 years
(D)21.The underlined word “it” in Paragraph 4 refers to ________.
A．the conservative estimate
B．a great push
C．the idea of living from 200 to 300 years
D．the idea of living beyond the present life span
(A)22.What would be the best title for this text?
A．Living Longer or Not
B．Healthy Lifestyle and Long Living
C．No Limit for Human Life
D．Science，Technology and Long Living

Did you think you could only see the emojis (表情符号) on your mobile phone？Well，think again.Museum of Modern Art in New York City recently received 176 emoji icons created by a Japanese communication company.Actually they came as a gift from Nippon Telegraph and Telephone Corporation.21cnjy.com
Emojis first appeared around 1999，but took a long time to become popular.They are now widely used all over the world.These icons will be shown in the same building as works that were created by artists like Andy Warhol，Claude Monet and Pablo Picasso.The emoji icons are only 12 pixels by 12 pixels.Some of them are in the shape of the moon，a video game controller，a cat，a car and even a high－heeled shoe.21教育网
In total，there are almost 1，800 emojis.The Unicode Consortium organization works to make sure computer data and computer code can be understood around the world.It was in 2010 that the organization translated the emojis into Unicode Standard.That means a person in France can send a message to someone in the US and the emoji will look the same to both.www.21-cn-jy.com
Visitors will be able to see the emojis in the museum now.In a letter on Twitter，a number of people said they could wait to see the emoji icons.They consider emojis a new language since some messages do not use traditional text.Paola Antonelli is with the Department of Architecture and Design at the museum.She said the idea of emojis went back hundreds of years and covered all of human history.There is nothing more modern than timeless concepts such as these emojis.
(A)23.What can we learn about the emoji icons?
A．They are in all shapes.
B．They were widely used in 1999.
C．Most of them are 12 meters high.
D．Andy Warhol first suggested the idea.
(D)24.The emojis were translated in Unicode Standard to ________.【来源：21·世纪·教育·网】
A．introduce a new coding system
B．send more messages to foreigners
C．help people use the computer better
D．make it easy for people to communicate
(B)25.In the last paragraph，Paola Antonelli tells us that ________.
A．the emojis will be shown on Twitter too
B．the emojis play a role in human history
C．the emojis are loved by modern people
D．the emojis are more simple than traditional text

Some students think it's more convenient to get the information.And you don't have to wait or get a tutor on the spot.Also，it improves students' abilities in communicating with others.【版权所有：21教育】

Nowadays，many students do homework with the help of the Internet，they search information online，or discuss through social networks like QQ or WeChat. Is it good or not？The students in our school had a discussion.【出处：21教育名师】
Some students think it's more convenient to get the information.And you don't have to wait or get a tutor on the spot.Also，it improves students' abilities in communicating with others.【版权所有：21教育】
However，it also brings about problems.Some students just copy the answers online without thinking.They become lazy.What's more，some students chat online for too long.
In my opinion，it is important to know how to use the Internet.The key is to have good self-control.No matter how difficult the problem is，first we should think about it independently.Be sure to understand the reasons behind the answers，or we won't make progress. 21教育名师原创作品
