Nearly every week, we hear news about the latest successes and failures in driverless vehicles. But we hear little about how other industries are developing this same kind of technology. One industry heavily involved in researching and developing artificial intelligence, or AI, is agriculture. Companies are experimenting with high-tech tools that can help farmers save time and money, while reducing environment-harming chemicals.
One of the companies is ecoRobotix of SwitzerLand, It created a robot equipped with AI and cameras to identify all plants on a farm The robot has four wheels to carry it through the fields in search of weeds. Computercontrolled arms then lower and spray the weeds with small amounts of herbicide(除草剂). Company officials say the robot can fully operate on its own for up to 12 hours a day while being powered by the sun It uses the same kind of sensor and positioning technology used to guide driverless vehicles. A farmer can also control the equipment through a smart-phone.
The co-founder of ecoRobotix, Aurelien Demaurex, says the farm robot can kill weeds with 20 times 1ess herbicide than traditional methods. This is because the system uses exactly the right amount of chemical in the exact place required to kill the weeds. Currently, farmers spread weed killers over massive areas to destroy unwanted plants.
Another company developing farm robotics is California-based Blue River Technology. The company has a system called "See & Spray", which it claims was the world's first smart sprayer. The system-which connects to the back of a tractor-is also equipped with AI to identify and chemically kill only the weeds. It can also spray chemicals on wanted plants to help them grow. Ben Chostner, vice-president of business development for Blue River Technology, explains in a company video that See & Spray technology uses the same deep Learning methods used in facial recognition. "The first time the machine saw a pigweed, it didn't know what kind of plant it was. But we taught it-by giving it tens of thousands of examples of that pigweed-and now it's an expert in pigweed. "
1.How will AI benefit agriculture?
A. It will fund agriculture research.
B. It contributes to low-cost farming.
C. It can avoid harmful chemicals.
D. It frees all farmers from field work.
2.What do the products of the two companies have in common?
A. They use recognition technology.
B. They are powered by solar energy.
C. They are connected with smart phones.
D. They can help wanted plants grow rapidly.
3.What do Ben Chostner's words suggest about the robot?
A. It is environmentally-friendly.
B. It is good at self-improving.
C. It has the learning ability.
D. It can track various plants.
4.What is mainly talked about in the text？
A. The experiment in farming robots.
B. New trend in artificial intelligence.
C. Modern See & Spray technology.
D. Artificial intelligence in agriculture.

I want to talk about the economy．Not "the economy" we hear about endlessly in the news each day and in politicians' speeches．I want to talk about the real economy, the one we live in day by day．
Most people aren't particularly interested in "the economy"．"Share prices are flying high; interest rates are soaring; the Dow Jones Index closed sixty-three points down on 8472．35．" We hear this and subconsciously switch off．
Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth．The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life．
We are supposed to be benefiting from all the advantages of a well-off society．So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives．Our towns become more and more crowded．We poison our air and seas, and our food is full of chemicals．There's something wrong here．If times were truly good, then you may think we'd all feel optimistic about the future．Yet the majority of us are deeply worried．More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations．
The term "economic expansion" suggests something desirable, but expansion simply means spending more money．More spending doesn't mean that life is getting better．We all know it often means the opposite - greed, crime, poverty, pollution．More spending merely feeds our whole economic system, which is based on production and consumption．Unless money keeps circulating, the economy breaks down．If we don't keep consuming, the whole system goes into stalemate（僵局）．
How do we break the cycle and make some changes? We need to become far more aware of the results of our actions．We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world．We create mountains of waste．We demand cheap food, mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land．
The consumption culture makes us unaware of the effect of our own behavior．Our main problem is not that we don't know what to do about it．It is gathering the desire to do it．
1.According to the author, which one belongs to the real economy?

Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet, or new plans to battle its effects like the one announced by President Barack Obama the other day. But the concept itself isn't new at all --- in fact, scientists have been exploring questions about climate change for almost 200 year.
The idea of “greenhouse gases” goes back to 1824, when Joseph Fourier wondered what was regulating the earth's temperature. Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat. As Fourier's ideas spread, it came to be called “the greenhouse effect”.
Scientists continued to study the greenhouse effect. Until a Swedish chemist named Svante Arrhenius came along, scientists understood how global warming actually works. After years of work, Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures.
Arrhenius found that CO2, and other gases trap radiation, which warms the atmosphere. Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect. But Arrhenius welcomed the warming effect on the planet. At a lecture later that year, Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.
While Arrhenius' findings won him the 1903 Nobel Prize in chemistry, scientists kept debating whether the greenhouse effect was increasing until 1950, when researchers finally began to find strong data supporting it. By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect – still, maybe Arrhenius should have been more careful of what he wished for.
1.What can we know from Paragraph 1?
A. Climate change has caused terrible disasters.
B. The topic of climate change has been talked a lot.
C. Scientists should work harder to research climate change.
D. The whole world should cooperate to protect the environment.
2.What does the underlined word “it” in Paragraph 2 refer to?
A. The atmosphere.
B. The idea.
C. The earth.
D. The earth's temperature.
3.What's the main idea of Paragraph 3?
A. Serious consequences of climate change.
B. The history of studying the greenhouse effect.
C. Significant research findings about climate change.
D. Scientists' doubts about the cause of global warming.
4.What did Arr henius think of the greenhouse effect?
A. It was beneficial for creatures on the earth.
B. It was totally responsible for climate change
C. It brought more troubles than benefits to human beings.
D. It worked as a punishment for human harmful activities.
5.What's the author's attitude towards Arr henius' expectation?
A. Cautious. B. Defensive. C. Positive. D. Negative.
