People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.
Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.
Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.

Grant Wood’s American Gothic caused a stir（轰动）in 1930 when it was exhibited for the first time at the Art Institute of Chicago and awarded a prize of 300 dollars. Newspapers across the country carried the story, and the painting of a farmer and a younger woman posed before a white house brought the artist instant fame.
In 1930, Grant Wood, an American painter with European training, noticed a small white house built in the small southern Iowa town of Eldon. Wood was so fascinated by it that he decided to paint the house along with the kind of people he thought should live in that house. In the painting, the farmer is modeled on his dentist. Dr. Byron McKeeby. His younger sister Nan served as a model for the woman （imagined to be the farmer’s wife or daughter）. Wood wanted to give a description of the traditional roles of men and women as the man is holding a pitchfork symbolizing hard labor. Each element was painted separately; the models sat separately and never stood in front of the house. The Gothic style of the house inspired the painting’s title.
American Gothic remains one of the most famous paintings in the history of American art. The painting has become part of American popular culture. Some believe that Wood used it to satirize（讽刺） the narrow-mindedness that has been said to characterize Midwestern culture. The painting may also be read as a praise of the moral virtue or rural America or even as a mixture of praise and satire. American Gothic is one of the few images to reach the status of cultural symbol, along with Leonardo da Vinci’s Mona Lisa.Which of the following is true about American Gothic?

What is a six-letter word that immediately comes to mind when you need some information on the Internet? You probably thought of Google. But Google wasn’t always the name of the famous search engine. In fact, the original name was BackRub!
BackRub was the name two graduate students gave to the new search engine they developed in 1996. They called it BackRub because the engine used backlinks to measure the popularity of Web sites. Later, they wanted a better name — a name that suggests huge quantities of data. They thought of the word googol. (A googol is a number followed by 100 zeros.) When they checked the Internet registry of names to see if googol was already taken, one of the students misspelled the word by mistake, and that’s how Google was born.
Google is just one example of a name change in the business world. Many other companies have decided to change their names or the names of their products. Here are some more examples:
Jerry Yang and David Filo, two young computer specialists, developed a guide to Internet content in 1994. They called it “Jerry and David’s Guide to World Wide Web.” But they soon realized that this wasn’t a very catchy name, so they searched through a dictionary and found a better one: “Yahoo.”
Sometimes companies change their names because of the popularity of one of their products. In 1962, a young runner named Phil Knight started a company called Blue Ribbon Sports. In 1971, Knight decided to design and manufacture his own brand of shoes. He named the shoes after the Greek goddess of victory — Nike. Nike shoes became so well known that Knight changed the name of the whole company to Nike.

While it may be unlikely for a computer to write a best seller, a technology expert has created a computer program that writes its own fiction stories with minimal user input. The program, called MEXICA, is the first to generate original stories based on computerized representations of emotions and tensions between characters.
An Internet survey was carried out to see the popularity of the computer-generated stories, other computerized stories and stories written solely by a human. The result was that readers ranked MEXICA stories highest for flow and coherence, structure, content, suspense and overall quality. Rafael Pérezy Pérez, the creator of MEXICA, explained that a story might begin with something as basic as, “The enemy wounded the knight. The princess cured the knight. The knight killed the enemy. The knight rewarded the princess. The end.”
The program reads characters as variables (变量) and assigns a numerical value, between a continuum (连续体) from -3 to +3, to emotional connections that are defined as either amorous or non-amorous. The numerical value is equivalent to the degree of emotion, with -3 being intense hate and +3 being intense love. The program also understands story tension, such as linking the word “wounded” with tension. This too is assigned a numerical value.
Once these clusters of emotional links and tensions are established, the program begins what is called an “engagement reflection cycle”. Basically this involves searching a database of story actions and other happenings, which are called “atoms”, and determines the best match for the characters and contexts for that moment.
The process repeats itself again and again until the system can no longer make any matches. At this point, the computer analyzes the story for coherence and “interestingness”. The program views a story as interesting when tension levels increase and fall throughout the piece. If the program finds that the story is boring or incoherent in places, it will replace or insert atoms until a version is thought to be satisfactory.What can we know about MEXICA from the passage?
| A．It is a computer program that can write fiction stories on its own. |
| B．It is a computer program created by Rafael Pérezy Pérez. |
| C．It is blamed for low quality among many other descriptors. |
| D．The stories it has written is not very popular among readers. |

| D．Emotions and tensions between characters should be determined. |
How does the computer system describe the characters in its story?
| A．Characters in the story are given different numerical values. |
| B．Characters are developed according to the tension preset. |
| C．Characters are designed by using the language MEXICA can understand. |
| D．Each character is valued for its value in the construction of the story. |

Pacing and Pausing
Sara tried to befriend her old friend Steve’s new wife, but Betty never seemed to have anything to say. While Sara felt Betty didn’t hold up her end of the conversation, Betty complained to Steve that Sara never gave her a chance to talk. The problem had to do with expectations about pacing and pausing.
Conversation is a turn-taking game. When our habits are similar, there’s no problem. But if our habits are different, you may start to talk before I’m finished or fail to take your turn when I’m finished. That’s what was happening with Betty and Sara.
It may not be coincidental that Betty, who expected relatively longer pauses between turns, is British, and Sara, who expected relatively shorter pauses, is American. Betty often felt interrupted by Sara. But Betty herself became an interrupter and found herself doing most of the talking when she met a visitor from Finland. And Sara had a hard time cutting in on some speakers from Latin America or Israel.
The general phenomenon, then, is that the small conversation techniques, like pacing and pausing, lead people to draw conclusions not about conversational style but about personality and abilities. These habitual differences are often the basis for dangerous stereotyping (思维定势). And these social phenomena can have very personal consequences. For example, a woman from the southwestern part of the US went to live in an eastern city to take up a job in personnel. When the Personnel Department got together for meetings, she kept searching for the right time to break in — and never found it. Although back home she was considered outgoing and confident, in Washington she was viewed as shy and retiring. When she was evaluated at the end of the year, she was told to take a training course because of her inability to speak up.
That’s why slight differences in conversational style — tiny little things like microseconds of pause — can have a great effect on one’s life. The result in this cause was a judgment of psychological problems — even in the mind of the woman herself, who really wondered what was wrong with her and registered for assertiveness training.What did Sara think of Betty when talking with her?
| A．Betty was talkative. |
| B．Betty was an interrupter. |
| C．Betty did not take her turn. |
| D．Betty paid no attention to Sara. |
According to the passage, who are likely to expect the shortest pauses between turns?
| A．Americans. | B．Israelis. |
| C．The British. | D．The Finns. |
We can learn from the passage that ________.
| A．communication breakdown results from short pauses and fast pacing |
| B．women are unfavorably stereotyped in eastern cities of the US |
| C．one’s inability to speak up is culturally determined sometimes |
| D．one should receive training to build up one’s confidence |
The underlined word “assertiveness” in the last paragraph probably means ________.
| A．being willing to speak one’s mind |
| B．being able to increase one’s power |
| C．being ready to make one’s own judgment |
| D．being quick to express one’s ideas confidently |
We once had a poster competition in our fifth grade art class.
“You could win prizes,’’ our teacher told us as she wrote the poster information on the blackboard. She passed out sheets of construction paper while continuing, “The first prize is ten dollars. You just have to make sure that the words on the blackboard appear somewhere on your poster.”
We studied the board critically. Some of us looked with one eye and held up certain colors against the blackboard, rocking the sheets to the right or left while we conjured up our designs. Others twisted their hair around their fingers or chewed their erasers while deep in thought. We had plans for that ten-dollar grand prize, each and every one of us. I’m going to spend mine on candies, one hopeful would announce, while another practiced looking serious, wise and rich.
Everyone in the class made a poster. Some of us used parts of those fancy paper napkins, while others used nothing but colored construction paper. Some of us used big designs, and some of us preferred to gather our art tidily down in one corner of our poster and let the space draw the viewer’s attention to it. Some of us would wander past the good students’ desks and then return to our own projects with a growing sense of hopelessness. It was yet another grown-up trick of the sort they seemed especially fond of, making all of us believe we had a fair chance, and then always — always — rewarding the same old winners.
I believe I drew a sailboat, but I can’t say that with any certainty. I made it. I admired it. I determined it to be the very best of all of the posters I had seen, and then I turned it in.
Minutes passed.
No one came along to give me the grand prize, and then someone distracted me, and I probably never would have thought about that poster again.
I was still sitting at my desk, thinking, What poster? when the teacher gave me an envelope with a ten-dollar bill in it and everyone in the class applauded for me.What was the teacher’s requirement for the poster?
| A．It must appear in time. |
| B．It must be done in class. |
| C．It must be done on a construction sheet. |
| D．It must include the words on the blackboard. |
The underlined phrase in paragraph 3 most probably means ________.
| A．formed an idea for |
| B．made an outline for |
| C．made some space for |
| D．chose some colors for |
After seeing the good students’ designs, some students ________.
| A．loved their own designs more |
| B．thought they had a fair chance |
| C．put their own designs in a corner |
| D．thought they would not win the prize |
We can infer from the passage that the author ________.
| A．enjoyed grown-up tricks very much |
