While astronauts in space get to do many exciting things，they miss out on ordinary things that we all 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（設(shè)備）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（面團(tuán)）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！

1.Why does the author mention the things that astronauts in space cannot do？

A． To ask us not to take common things for granted．

B． To show they live a difficult life there．

C． To show their life is boring in space．

D． To introduce the topic of the text．

2.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

3.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

4.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

As far as I can remember, grow up in Ohio left many good memories and very few bad ones. We rented a home near a lake where I spent good time of my life. I attended to school to learn a variety of course, and went camping overnight in the woods. My dog and I would go fishing in the lake that I mentioned early. During the winter we will come down at night and go ice-skating on the lake. In Ohio the snow could be heavily sometimes and too deep to walk in as I was not that tall at the time. It was not until I was sixteen and moved to California when the life was changed. This was a tough change for me because the area total differed from Ohio. There was no rivers or lakes to fish in at all.

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.

Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. “We've been going to the same spot in the Pacific Ocean, and we try and characterize long?term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean.”

Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.

“As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid，” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the PH down, and makes it more acidic.”

The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.

The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.

“It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic.”

1.What can be the best title of the passage?

A．Climate Change Affecting Seawater

B．Oceans Becoming More Acidic

C．Sea Life Facing Danger

D．Scientist Researching Seawater

2.With the increase of atmospheric CO2，________.

A．the surface water is becoming warmer

B．more corals will appear in the sea

C．the PH of the ocean out here has been increasing

D．the chemical balance of the seawater is affected

3.Which of the following shows the process of the impact of atmospheric CO2 on sea life?

a．Sea life is endangered.

b．CO2 goes into the surface water.

c．The ocean chemistry is affected.

d．CO2 decreases the PH and makes the seawater more acidic.

e. CO2 levels in the atmosphere go up.

A．a(chǎn)→e→b→c→d B．e→d→c→b→a

C．e→b→c→d→a D．a(chǎn)→b→c→d→e

One hot night last August, I tried everything I could think of — toys, songs etc. to make him fall into sleep, but he just couldn’t do it. Since I believed that a long night was waiting for me ahead, I had no choice but to bring a TV into his room to kill off the hours until dawn. I was surprised that the moment I turned on the TV the baby became quiet right away and fixed his little eyes brightly on the screen. Not willing to waste an opportunity for sleep, I then tiptoed(躡手躡腳地行進(jìn)) out of the room, leaving him to watch the boring TV programs. I heard no more of the baby’s crying that night and the next morning when I went into his room, I found him still watching TV by himself. I found there was a metaphor(暗喻) in my baby’s behavior(行為) for the new generation. When I gave my boy some books to go over, he only spit upon them; when I read to him, he did not feel comfortable. And so it is in the schools with my students. I find that our students don’t read and they look down upon reading and make light of those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have drawn a conclusion: “Let them watch it!” If television is that much more attractive to children than books, why should we fight against it? Let them watch what they want！

1. Why did the father bring a TV set into his son’s room?

A. To enjoy some interesting programs together with his son.

B. To help himself pass the long hours ahead of him.

C. To help his son fall asleep sooner.

D. To keep his son from making noises.

2.The baby seemed to be ______ at the sight of the TV set.

A. excited B. surprised C. bored D. pleased

3.This experience with his baby helped the father ______.

A. to know his baby better

B. to know better how to educate his students

C. to change his opinions towards TV

D. to know better about the new generation

One morning, my husband Jerry went back to the kitchen as he just finished loading his car. “I guess filling my thermos(保溫瓶) is all that I have left to do, and then I’m off.” Down the drain went the hot water that had been warming his thermos.

With a nostalgic(懷舊的) look on his face, he softly said: “Anytime I fill my thermos I think of your mom.” The tone in his voice was so tender as he spoke of my mother, who is sadly no longer with us.

“Oh honey, I know she’s watching and listening right now with a big smile on her face,” I responded, tears in my eyes.

One morning years ago when we were leaving, mother watched as Jerry was to fill his thermos. Mom then casually said, ‘Jerry, if you filled your thermos with hot water and let it sit a while, your coffee would stay hot for longer then.” With her simple suggestion, his face showed that he was shocked by his own lack of common sense. Well, of course it would!

He poured out the small amount of coffee already in the thermos and refilled it with boiling hot water. Then he poured the water and refilled it with hot coffee. Mom smiled as Jerry did so.

Words of wisdom from a loving mother-in-law made an impact that will never be forgotten. She never dreamed her words would be a treasured and everlasting memory in the heart of her son-in-law.

The lasting memories don’t necessarily come from major moments in life. Memories are often made during those small, ordinary times. Life is about small moments we share with friends and loved ones.

1.Which word best describes the author’s feeling in Paragraph 3? ____

A. Confused B. Concerned

C. Touched D. Interested

2.The underlined part “don’t necessarily” is similar in meaning to ________.

A. out of the question

B. without any doubt

C. certainly and absolutely

D. possibly but uncertainly

3. The message that the story intends to convey is ______.

A. how valuable a mother’s advice is to her children.

B. that lasting memories come from small things

C. what a wise woman the mother is to her son-in-law

D. why we should respect our parents and listen to them.

According to figures released by the Office for National Statistics (ONS)，the U．K．has about 7．7 million families with dependent children，of which 3．7 million have just one child，compared to 3 million with two and 1．1 million with three children or more．The number of families today with just one dependent child is now 47 percent and will likely rise to more than 50 percent in a decade．As the ONS confirms，“It appears that families are getting smaller．”
One obvious reason for this could be that women are putting off having children until they have established careers when they are bound to be less fertile．But it could just as well be a matter of choice．Parents must consider the rising cost of living，combined with economic uncertainty and an increasingly difficult job market．And this trend may continue growing as having an only child becomes more normal，which seems to be the mood on the mothers’ online forum Mumsnet，where one member announced that she “just wanted to start a positive thread about how fab it is to have an only child”．
She had received 231 replies，overwhelmingly in the same upbeat spirit．Parents of only children insist there are plenty of benefits．Nicola Kelly，a writer and lecturer who grew up as an only child and is now a married mother of one，says her 15-year-old son seems more grown-up in many ways than his contemporaries．
Not all products of single-child families are as keen to repeat the experience．In a moving recent account journalist Janice Turner wrote about her own keenness to “squeeze out two sons just 22 months apart”as a reaction to her only-child upbringing．
She was placed on a pedestal by her doting parents，whom she punished with a “brattish，wilful” rejection of everything they stood for．Desperate for a close friend she was repeatedly shattered by rejection and refers to her childhood as being “misery”．
Writer and clinician Dr．Dorothy Rowe，a member of the British Psychological Society，says that we all interpret events in our own individual way and there are some children who no matter what their circumstances feel slighted，while other children see the advantages of their situation．
However，the one part of life that is unlikely to get any easier for only children is when they grow up and find themselves looking after their own parents as they become older．
1.The passage is written with the purpose of ________．
A． illustrating the strength and weakness of having an only child
B． analyzing the reasons why having an only child becomes popular
C． presenting us with different opinions about having an only child
D． guiding people to look at the same issue from different perspectives
2.What does the underlined sentence in Paragraph 4 mean？
A． Nearly half of families intend to have just one child．
B． All people don’t stand for the idea of having an only child．
C． Some people fail to recognize the advantage of having an only child．
D． People brought up in an only child family resist downsizing the family．
3.From what Dr．Dorothy Rowe said，we know that ________．
A． journalist Janice Turner experienced a miserable childhood
B． she has a positive attitude towards Janice Turner’s reaction
C． it’s necessary for us to look at the event from our own angle
D． some are unable to make an objective assessment of their conditions
4.What can be inferred from the passage？
A． It’s normal to see the imperfection in character in only children．
B． Mumsnet is an online forum which promotes having an only child．
C． Economic development plays a determining role in the family size．
D． Only children will have difficulty in attending to their parents．
