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(设备)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(面团)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!
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.

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

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

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

Michael J. “Crocodile Dundee” (also called Mick), played by Paul Hogan, is the main character in the fictional Crocodile Dundee film series consisting of Crocodile Dundee, Crocodile Dundee II, and Crocodile Dundee in Los Angeles. The character is a crocodile hunter, hence the nickname.
In the first film, Crocodile Dundee, Mick is visited by a New York reporter, Sue Charlton, who travels to Australia to investigate a report when she heard of a crocodile hunter, who had his leg bitten off by a crocodile in the outback. The hunter supposedly walked more than a hundred miles back to civilization and miraculously survived his injuries. However, by the time she meets him, the story turns out to be a somewhat exaggerated legend where the “bitten-off leg” turns out to be just being some bad scarring on his leg; a “love bite” as Mick calls it. Still interested by the idea of “Crocodile Dundee”, Sue continues with the story. They travel together out to where the incident occurred, and follow his route through the bush to the nearest hospital. Despite his old-fashioned views, the pair eventually become close, especially after Mick saves Sue from a crocodile attack.
Feeling there is still more to the story, Sue invites Mick back to New York with her, as his first trip to a city (or “first trip anywhere,” as Dundee says). The rest of the film depicts Dundee as a “fish out of water,” showing how, despite his expert knowledge of living outdoors, he knows little of city life. Mick meets Sue’s boyfriend, Richard, but they do not get along. By the end of the film, Mick is on his way home, lovesick, when Sue realizes she loves Mick, too, and not Richard. She runs to the subway station to stop Mick from leaving and, by passing on messages through the packed-to-the-gills crowd, she tells him she won’t marry Richard, and she loves him instead. With the help of the other people in the subway, Mick and Sue have a loving reunion as the film ends.
Which of the following statements is true about Mick?

A.He is a crocodile hunter living in Los Angeles.
B.He got his nickname because of his job.
C.He wrote a film series about himself.
D.He is based on a real person in Australia.

In the film Crocodile Dundee, Mick ______.

A.pretends he was bitten by a crocodile
B.urges Sue Charlton to write his life story
C.hasn’t been abroad before his trip to America
D.shows Sue Charlton around the town he lives in

When in New York, Mick ______.

A.makes friends with Richard
B.makes full use of his bush skills
C.feels excited about living in a big city
D.doesn’t know how to fit into city life

No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus on doing one specific job.
Let’s take a man we’ll call Mr. Fielder for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn’t make the bricks for his house, cut his trees into boards, make the plows, or any of other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people’s attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this earliest form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today’s world.
What probably led to the start of advertisement?

A.The discovery of iron.
B.The development of farming techniques.
C.The appearance of new jobs.
D.The specialization of labor.

The writer makes up the two stories of Mr. Fielder and Mr. Plowright in order to __________.

A.explain the origin of advertising
B.predict the future of advertising
C.provide suggestions for advertising
D.expose problems in advertising

In ancient Egypt, a crier was probably someone who __________.

A.had the loudest voice
B.took possession of a ship
C.functioned like today’s TV or radio commercial
D.ran a shop selling goods to farmers

The last two paragraphs are mainly about __________.

A.the basic design of advertising
B.the early forms of advertising
C.the benefits of advertising
D.the history of advertising

Accurately forecasting the weather is a very hard thing to do. There are many parts of weather dynamics — the study of how water and air in motion cause weather patterns — to consider. Even the best forecast can be changed by a small weather disturbance halfway around the world. Today’s forecast use complex computer models, weather instruments, and detailed analyses of daily observations to predict the weather. However, it hasn’t always been that way. People, like your grandparents, use folklore and proverbs to help forecast the weather. They remembered what conditions caused changes and observed the factors associated with weather: atmospheric and cloud conditions, temperature, winds, and reactions of plants and animals. Many people believe that this way of forecasting weather is accurate more often than modem forecasting.
Grandma’s aching joints might indicate the arrival of a low-pressure system. She might also observe the geese flying lower than usual, confirming the low-pressure system. Finally, she might feel dampness on her skin, a sign of high humidity (湿度). Based on these three observations, grandma might warn that a storm is brewing.
Joints and nerves can indicate dropping air pressure, dissolved gases in the blood form bubbles under low air pressure. This causes pain in joints and nerve endings. Geese and other birds respond to changes in air pressure by adjusting how high they fly. In the fair, calm weather of a high-pressure system, the birds fly higher than in the stormy weather associated with a low-pressure system.
Nature provides other clues to changing weather. A decrease in air pressure causes deer and elk to come down from the mountains to look for shelter. Some animals feed more than usual. The higher humidity before a storm causes some insects to leave the trees and gather near the ground. Some flowers close so rain doesn’t get inside them. In winter, rhododendron plants curl up to protect themselves as the temperature drops.
Several of the sayings apply in particular areas of the world. Here are some of them.
■Early thunder, early spring.
■Rainbow in the morning gives you fair warning.
■When teeth and bones ache, expect the clouds to fill the lake.
■When high clouds and low clouds do not match together, prepare for a blow and a change in the weather.
It is true that ___________.

A.using folklore and proverbs to forecast weather is more accurate than modem forecasting
B.complex computer models and weather instruments can always forecast weather accurately
C.modern forecasting cannot always guarantee accurate weather forecasting for some reason
D.modem forecasting along with other observations is sure to give accurate weather forecast

A.some birds will be seen flying near the surface of the earth
B.some flowers close so rain doesn’t get inside
C.some animals come down from mountains
D.some insects disappear from ground

It is a fact that the behavior of plants and animals is _________.

A.likely to reflect long-term weather forecasting
B.likely to reflect short-term weather forecasting
C.unlikely to reflect any kind of weather forecasting
D.more likely to reflect both short-term and long term weather forecasting

What does the passage mainly tell us?

A.People can forecast weather with no modern equipment.
B.How to use proverbs to forecast weather forecasting.
C.Hard as it is, weather forecasting has a scientific base.
D.The importance of weather forecasting.

Pride and Prejudice for the Modern Woman
Let us imagine how Pride and Prejudice, Jane Austen's most famous work, might be updated, 200 years on. Austen's popularity is rooted in her intelligence. But today she would certainly have had a very different life, as would her characters. Here's my own suggestion. . .
It is a truth finally and universally acknowledged that a single woman with brains deserves to have equal opportunities to men, however disadvantaged she may feel by sexism.
"My dear husband," said his hopeful wife one day, "have you heard that the local store, standing empty for so long, is taken over by a bright young businesswoman?"
Her dull and indifferent (漠不关心的) husband replied that he had not. "But it is, it is," she replied excitedly. Mr Dull-Husband made no reply.
"Don't you want to know her plans?" she cried with some impatience.
"Well, clearly you think it matters to your silly little head… so I'd better listen. "
"Well, my dear, the rumour (传言) is that she has already set up a string of successful businesses in northern England, though how a woman can know anything about that is beyond me. She will move in herself next month. "
"What is her name?"
"Bingley.”
"Is she married or single?"
"What a question! And none of your business. But her coming will be good for our five boys. "
"How so? How can it possibly affect them? "
"My dear love; those lazy boys need something to wake them up. There are sure to be jobs going."
"Is that her point in settling here? Surely as a woman she has simply taken a fancy to the place."
"Nonsense, my love, how little you've noticed the world has changed. She's got a first-rate degree and some sort of business qualification, I'm told. She surely needs one of our boys! Perhaps you might give her a call. "
"Me? No. Perhaps you can take an interest. You still have your looks, after all. She may even offer you a job. "
"Oh, that's not likely. These new chances belong to the younger generation. But now you mention it, I think I'll go along all the same. "
And Mrs. Bennet went along. That was 10 years ago. She is now managing director of a FTSE-listed company.
... It would remain the case, of course, that Mrs. Bennet would be one of very few women on the company board, that her salary would be lower than her male colleagues, her bonus of a more "female" dimension and her lifespan (年限) among the city's business leaders shorter than theirs. Still, she'd no doubt have enjoyed Davos (达沃斯经济论坛)—and might even have hobnobbed (攀谈) with influential figures.
