As the world’s population grows, farmers will need to produce more and more food. And large farms are increasingly using precision farming to increase yields (产量), reduce waste, and reduce the economic and security risks that inevitably accompany agricultural uncertainty.

Traditional farming relies on managing entire fields—making decisions related to planting, harvesting, irrigating, and applying pesticides and fertilizer (农药和化肥)—based on regional conditions and historical data. Precision farming, by contrast, combines sensors, robots, GPS, mapping tools and data-analytics software to customize（量身定制）the care that plants receive without increasing labor. Robot-mounted sensors and camera-equipped drones (无人机) wirelessly send images and data on individual plants to a computer, which looks for signs of health and stress. Farmers receive the feedback in real time and then deliver water, pesticide or fertilizer in adjusted doses（剂量）to only the areas that need it. The technology can also help farmers decide when to plant and harvest crops.

As a result, precision farming can improve time management, reduce water and chemical use, and produce healthier crops and higher yields—all of which benefit farmers’ bottom lines and conserve resources while reducing chemical runoff.

Many small businesses are developing new software, sensors, and other tools for precision farming, as are large companies such as Monsanto, John Deere, Bayer, Dow and DuPont. The U.S. Department of Agriculture, NASA and the National Oceanic and Atmospheric Administration all support precision farming, and many colleges now offer course work on the topic.

In a related development, seed producers are applying technology to improve plant characteristics. By following individual plants over time and analyzing which ones flourish in different conditions, companies can relate the plants’ response to their environments with their genomics (基因组学). That information, in turn, allows the companies to produce seed varieties that will grow well in specific soil and weather conditions. This advanced technology may also help to improve crop nutrition.

Farmers do not universally welcome precision agriculture for various reasons, such as high equipment costs and lack of access to the Internet. The technology may bring great challenges to experienced farmers who are not good at computers. And large systems will also be beyond the reach of many small farming operations in developing nations. But less expensive, simpler systems could potentially be applied. For others, though, cost savings in the long run may reduce the financial concerns. And however reticent some farmers may be to adopt new technology, the next generation of farmers are likely to warm to the approach.

1.Precision farming differs from traditional farming partly because it ________.

A. guarantees high yields with more labor

B. relies on regional conditions and historical data

C. offers plenty of water, pesticides and fertilizer

D. provides real time information about target crops

2.About precision farming, we can learn that________.

A. the government holds a cautious attitude

B. it draws positive responses from businesses

C. seed producers have already made huge profits

D. large systems will soon be built in developing nations

3.The underlined word “reticent” in the last paragraph probably means ________.

A. disappointed　　 B. confused

C. unwilling　　 D. shocked

4.What is the best title for the passage?

A. Precision Farming Increases Crop Yields

B. More Challenges Faced by Modern Farmers

C. Development of Farming Systems in the U.S.

D. Traditional Farming is Gradually Disappearing

Why do Chinese people love hot pot so much? As the winter months are coining in, more and people are silting around a table, enjoying this kind of traditional meal. I find myself wondering what it U about this traditional meal, which has existed for more than 1,000 years. What makes it a Chinese food favorite? It seems that the answer lies beyond the dish itself.

Hot pot isn’t just designed to keep you warm during the cold months; it’s also a social experience. It’s a “theater” cooked food that turns a meal into an event. There is a lot of fun for everyone to have in adding some foods to the hot pot.

Hot pot is eaten over two to three hours. For this reason, it is often considered an evening’s entertainment, and a time to spend with friends and families. However, many westerners would be put off by the idea of other people sticking chopsticks in their food. When we come to eat at the table in the UK, we tend to have our own shares, although the experience is still a social one.

A similar experience to the hot pot can be found in Korean barbecue restaurants, which lei you cook your own meat. This allows people to have their meat done however they want.

For most westerners, the idea of going to a restaurant to cook their own food is very strange. But having a go, I find it’s now one of my favorite meals in Beijing. The steam from the pot left my clothes smelling of food when I got home, but perhaps this was also part of the experience. When the cold wind is blowing outside, I am sitting around with my good friends, eating and drinking. For me it’s like a dinner party where my taste buds and my appetite are equally satisfied in the warm company of friends.

1.What is the main reason why hoi pot is popular in China?

A. It has a history of over 1,000 years.

B. It is a fun social experience.

2.We can conclude from the article that British people generally　　　　　 .

A. enjoy cooking their own food in restaurants

B. prefer a Korean barbecue to Chinese hot pot

C. don’t like sharing food with others in restaurants

D. don’t mind the smell of food staying on their clothes

3.How long do people spend in enjoying the traditional meal?

A. More than four hours.　　 B. Over one hour.

C. About three hours.　　 D. All the evening.

4.What is the author’s attitude to hot pot?

A. Serious.　　 B. Tired.

C. Humorous.　　 D. Appreciative.

Although the United States covers so much land and the land produces far more food than the present population needs, its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林业), and most of the rest live in or around towns, small and large. Here the traditional picture is changing: every small town may still be very like other small towns, and the typical small town may represent a widely accepted view of the country, but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(large cities with their suburbs ) of more than a million people each – a large proportion than in Germany or English, let alone France. The statistics(统计) of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues, rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment.

3.What’s the meaning of the word “metropolitan” in the middle of the passage?

A. Of a large city with its suburbs．

C．Of urban areas．

D．Of rural areas．

4.　 According to the passage，what can we learn about small towns in the United States?

A．Most small towns become gradually crowded．

B．Small towns are still similar to each other．

C．As the traditional picture is changing，towns are different．

D .Small towns are turning into large cities．
