Today just as technology changed the face of industry, farms have experienced an “agricultural revolution”. On the farm of today, machines provide almost all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock(家畜) to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for pig producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make shocking changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear（修剪） sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete change of the farm is far in the future, but engineers expect that some robots will be used before long.

Today, the bicycle is the primary method of transportation for the human race. About 1.6 billion bicycles are in use around the world --- in big cities, along remote country lanes, and in the smallest villages ---and hundreds of millions of bikes are produced every year to meet the continuing demand for cheap wheeled transport.
Yet the bicycle is hardly a new vision of how humans move around. Historians speculate(猜测) about Leonardo da Vinci’s 1940s drawings and a 1580s stained glass window in England that appear to describe a two-wheeler. The first widely recognized two-wheeler in actual use, however, was the pedal-less Celerifere, a toy of the French upper class in the 1970s. The more famous Draisienne followed that toy in 1816, still without pedals. The front wheel could be steered, and this two-wheeler was eventually mass-produced in Europe, particularly in England. Ernest Michaux added cranks(曲轴) to the two-wheeler in 1855, which started a revolution in human transportation --- the Velocipede.
By 1870, complicated metal Velocipede were in production in Europe and the United States. Over time, they gave way to the “Ordinary” or high-wheeler. The Ordinary was the beginning of the heyday(全盛期) of bicycling. It was speedy and capable of long trips on poor roads, so it was soon in widespread use. At that time a skilled person might earn 25 cents an hour in wages, but a good Ordinary sold for $75 to $125, making it more expensive than building a house. Nevertheless, they sold at a furious pace.
Ordinaries had a big problem, however. When the front wheel came up against any obstacle that it could not roll over, the bike simply threw the rider headfirst onto the ground. Called a “header”, this characteristic problem inspired the “safety bicycle” in the 1980s. With two wheels of equal size, plus a roller chain(齿轮) transmission, the safety bicycle was with a slight adaptation, they attracted thousands of women to cycling. Many historians point to the safety bicycle as the beginning of women’s rights.
In England, in 1909, the Raleigh bicycle, equipped with a 3-speed hub, started to be produced. In the 1930s, British-built “lightweight” bicycles, suitable for the packed earth of country roads, were being imported into the United States. The early 1980s saw the creation of the “Freestyle” or trick bicycle. And in the late 1990s, the road bike and the mountain bike proved to be the dominant machines of the decade.

There are no signs of little green men on Mars. But new discoveries offer a bit more hope that some form of life existed there in the past --- and perhaps is still there in the present. Methane gas(甲烷) and water have been found on the Red Plane. The presence of both suggests at least the possibility of life.
According to a new report in the journal, Science, the Mars rover, Curiosity, has detected spikes of methane in the Martian atmosphere. This gas is also found in the Earth’s atmosphere, and comes from animal and plant life, as well as from the environment itself. If there’s methane in Mar’s atmosphere, where is it coming from? Scientists aren’t sure. But it marks a big change. In September 2013, Curiosity found almost no traces of methane in the Martian air. Just weeks later, however, the rover picked up a whiff of(一点点) the gas.
The scientists don’t know whether the methane spikes are caused by some form of biological matter or by the geology of the planet. Christopher Chyba, a professor of astrophysics and international affairs at Princeton, says it’s best not to be too hopeful about biology on the Red Planet. “Hopes for biology on Mars have had a way of disappearing once Martian chemistry has been better understood,” he says. “But figuring out what’s responsible for the methane is clearly a key astrobiological objective --- whatever the answer turns out to be.”
The discovery of water on Mars is nothing new. For decades, scientists have had evidence that it flowed across the surface of the planet billions of years ago. But according to another new report in Science, while the surface water on Mars seems to be long gone, there’s a lot more of it left than most of people realize.
This report is also based on findings from Curiosity. Paul Mahaffy, of NASA’s Goddard Space Flight Center in Maryland, led the study. He says there is enough water on Mars “to cover the surface to a depth of about 165 feet.”
It is not easy to reach this water. Most of it is locked up in ice at the planet’s poles.Why do scientists think there might be life on Mars?
| A．Because the Mars rover has detected water on the planet. |
| B．Because there is evidence that little green men exist on the planet. |
| C．Because the Mars rover has found some plants on the planet. |
| D．Because both methane and water have been found on the planet. |
What is the attitude of professor Christopher Chyba towards life on Mars?
| A．Optimistic | B．Negative |
| C．Neutral | D．Indifferent |
The water on Mars _______________.
| A．still flows on its surface |
| B．covers the whole planet |
| C．is locked up in ice at the planet’s poles |
| D．only existed on it billions of years ago |

Before we start a voyage, we usually try to find out more or less definitely where we are bound and how we are supposed to get there.
I happen to have the “Concise Oxford dictionary” on my desk and that will do as well as any other. The word I am looking for appears at the bottom of Page 344. edition 1912.
“Geography: the science of the earth's surface, form, physical features, natural and political divisions, climate, productions and population.”
I could not possibly hope to do better, but I still stress some of the aspects of the case at the expenses of others, because I intend to place man in the centre of the stage. This book of mine will not merely discuss the surface of the earth and its physical features, together with its political and natural boundaries. I would rather call it a study of man in search of food and shelter and leisure for himself and for his family and an attempt to his background or has reshaped his physical surroundings in order to be comfortable and well nourished and happy with his limited strength.
Among the two million human beings in the world, there is of course the widest possible range for all sorts of experiments of an economic and social and cultural nature. It seems that those experiments deserve our attention before anything else. For a mountain is after all merely a mountain until it has been seen by human eyes and has been walked on by human feet and until its slopes and valleys have been occupied and fought over and planted by a dozen generation of hungry settlers.
The Atlantic Ocean was just as wide and deep and as wet and salty before the beginning of the 13th century as after, but it took the human touch to make it what it is today—a bridge between the New World and the Old, the highway for the commerce between East and West.
For thousands of years the endless Russian plains lay ready to offer their abundant harvest to whoever should take the trouble to sow the first grain. But the aspect of that country today would he a very different one if the hand of a German or a Frank, rather than that of a Slav, had guided the iron-pointed stick that plowed the first furrows (犁沟).
The island of Nippon would shake and quake just as continually, whether they happened to be settled by Japanese or by the Tasmanian race, but in the latter case they would hardly be able to feed 60,000,000 people.
Generally speaking, I have paid more attention to the purely “human” side of geography than to the commercial problems which are so important in a day and age devoted to mass production.In the first four paragraphs, the author wants to share with the readers ______.

Once again, the time has come for the biggest event in the fashion world: New York Fashion Week! But do you know enough about this annual event to call yourself a true fashionista?
From seating arrangements to model behavior, here are some things you might not know about Fashion Week.
___________________
At Fashion Week, it’s where you sit that counts. A-list attendees include the fashion media, buyers, retailers, fashion professionals, celebrities and socialites, but who gets the coveted front-row seats comes down to the designers and their PR teams. Usually, it’s celebrities and important editors who get the best seats.
Why do models always look so unhappy?
Models usually parade along the runway with serious expressions on their faces. Well, it’s not that they’re too cool to smile. Most high fashion designers typically ask their models not to smile while walking down the runway. The idea is that audience members will concentrate on the fashion designs instead of the model’s face or personality. “It’s more than anything else about doing the job well,” supermodel Claudia Schiffer told Reuters.
How should Fashion Week attendees behave?
Designers appreciate it when attendees wear their brand to their show. Most design houses will even ensure that the celebrities are “appropriately” dressed in designer wear once they agree to attend.
Catwalk photographers hate it when the audience’s feet sully their pristine runway shots, so just as the lights go down, they scream a single message to the audience: “Uncross your legs, please!”
How do the Big Four fashion weeks differ?
The Big Four always take place in this order: New York, London, Milan and Paris. Each of the Big Four is known for championing different styles — New York for sportswear; London for edgy, avant-garde design; Milan for its over-the-top yet stylish looks; and Paris for haute couture.which of the following is the most suitable heading for the third paragraph?
| A．Who attends fashion week? |
| B．Who gets a first-row seat? |
| C．Which seats are the best? |
| D．What counts at the fashion week? |
why do models always look so unhappy/
| A．They are too cool to smile |
| B．They are used to wearing serious expressions. |
| C．Audience will focus on the fashion designs rather than models’faces. |
| D．They will be fined if they smile while parading. |
we can learn from the passage that ____.
| A．London fashion week is known for sportswear |
| B．Fashion week attendees can be dressed however they like |
| C．The audience can cross their legs all through the show |
| D．Celebrities and important editors usually sit in the front row |
The main purpose of the passage is to ____
A.A.Advertise some fashion designs
B.advise people to attend fashion week
C.Introduce some knowledge about fashion week
D.Tell fashion week attendees how to behave

Alice’s mother died when Alice was five years old. Alice, who grew up to be my mother, told me that after her mother’s death her family was too poor to even afford to give her a doll.
In December 2012, I had a job at a local bank. One afternoon, we were decorating the tree in the bank lobby(大厅). One of my customers approached me with her beautiful handmade dolls. I decided to get one for my daughter, Katie, who was almost five years old. Then I had an idea. I asked my customer if she could make me a special doll for my mother—one with gray hair and spectacles(眼镜): a grandmother doll. And she gladly agreed.
A friend had told me that his dad who played Santa Claus would be willing to make a visit on Christmas morning to our home to deliver my Katie her presents, so I made some special arrangements.
Christmas Day arrived and at the planned time; so did Santa Claus. Katie was surprised that Santa had come to see her at her own house. As Santa turned to leave, he looked once more into his bag and found one more gift. As he asked who Alice was, my mother, surprised at her name being called, indicated that she in fact was Alice. Santa handed her the gift, with a message card that read:
For Alice:
I was cleaning out my sleigh(雪橇) before my trip this year and came across this package that was supposed to be delivered on December 25,1953. The present inside has aged, but I felt that you might still wish to have it. Many apologies for the lateness of the gift.
Love,
Santa Claus
My mother’s reaction was one of the most deeply emotional scenes I have ever seen. She couldn’t speak but only held the doll she had waited fifty-nine years to receive as tears of joy ran down her cheeks. That doll, given by “Santa”, made my mother the happiest “child” that Christmas.Why couldn’t the writer’s mother have a doll when young ?_________.
| A．Santa Clause forgot to send the doll to her |
| B．her daughter couldn’t make a doll by herself |
| C．her parents left the doll in the Santa Clause’s sleigh |
| D．her family was badly off when she was a child |
What can be inferred from the passage ?__________.
| A．the writer’s father played the Father Christmas |
| B．the writer’s mother was already in her sixties when she received the doll |
| C．the writer urged one of her friends to make the doll for her mother |
| D．the Santa Clause was too careless to deliver the doll on time |
The best title for this passage could be __________.
| A．A Doll from Santa |
| B．An unforgettable Christmas |
| C．A considerate daughter |
| D．A help from Santa Claus |
