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
B. attract more companies to work for NASA
C. help astronauts in space enjoy fresh pizza one day
D. produce pizza in large quantities to earn great profits
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

When I was six, Dad brought home a dog one day, who was called “Brownie”. My brothers and I all loved Brownie and did different things with her. One of us would walk her, another would feed her, then there were baths, playing catch and many other games. Brownie, in return, loved each and every one of us. One thing that most touched my heart was that she would go to whoever was sick and just be with them. We always felt better when she was around.
One day, as I was getting her food, she chewed up(咬破)one of Dad’s shoes, which had to be thrown away in the end. I knew Dad would be mad and I had to let her know what she did was wrong. When I looked at her and said, “Bad girl,” she looked down at the ground and then went and hid. I saw a tear in her eyes.
Brownie turned out to be more than just our family pet. She went everywhere with us. People would stop and ask if they could pat her. Of course she’d let anyone pat her. She was just the most lovable dog. There were many times when we’d be out walking and a small child would come over and pull on her hair. she never barked(吠) or tried to get away. Funny thing is that she would smile. This frightened people because they thought she was showing her teeth. Far from the truth, she loved everyone.
Now many years have passed since Brownie died of old age. I still miss days when she was with us.
1.What would Brownie do when someone was ill in the family?
A. Look at them sadly. B. Keep them company.
C. Play games with them. D. Touch them gently.
2.We can infer from Paragraph 2 that Brownie______.
A. would eat anything when hungry
B. felt sorry for her mistake
C. loved playing hide-and-seek
D. disliked the author’s dad
3.Why does the author say that Brownie was more than just a family pet?
A. She was treated as a member of the family.
B. She played games with anyone she liked.
C. She was loved by everybody she met.
D. She went everywhere with the family.
4.Some people got frightened by Brownie when she______.

The Meaning of Dreams
Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.
1. First, we have most of our dreams during REM(rapid eye movement)sleep. At this time, the brain is very active. Second, everyone dreams, even if we can't remember doing so when we awaken. 2. While we are sleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.
3. . Some believe that our dreams are associated with thoughts and feelings that we experience while we are awake. Many dream researchers think that a dream about death, for example, is really about an important life change. 4. . Dreams about a car or travel often represent (代表) feelings about your own life. Dreams about teeth—especially broken or loose ones—may indicate(预示) stress or fear. Dreams in which you are flying often represent freedom or escape.
Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling, for example, maybe you are angry. 5. . There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.
A. Dreams may be more important than sleep.
B. Scientists do not know for certain why we dream.
C. If he or she was scared then maybe you are afraid of something.
D. Modern research can tell us some important things about dreams.
E. There are three things you should pay attention to have a sweet dream.
F. Finally, a part of our brain helps us to understand daily experience we have.
G. Dreams about telephones are thought to be about giving or receiving messages.
