阅读理解

    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

    Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying. {#blank#}1{#/blank#} However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace (支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

    Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position.

    Undo your seatbelt. {#blank#}2{#/blank#} Untie the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.

    {#blank#}3{#/blank#} Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.

    Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. {#blank#}4{#/blank#}

    Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. {#blank#}5{#/blank#} While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. Surviving a sinking car is not as difficult as you think.

C. It takes 60 to 120 seconds for a car to fill up with water usually.

D. Such accidents are particularly dangerous to the risk of drowning.

E. In conclusion, if you know what to do in the water, you will be safe.

F. This is the first thing to attend to, yet it often gets forgotten in the panic.

G. But the sooner the window is open, the sooner you can escape directly through it.

    A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops.

    Students are increasingly using laptops for note­taking because of speed and legibility(清晰度).But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes“mindlessly”by taking down word for word what the professors said.

    In the first experiment,students were given either a laptop or pen and paper.They listened to the same lectures and were told to use their usual note­taking skills.Thirty minutes after the talk,they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand.However,the typists performed worse at remembering and applying the concepts.Both groups scored similarly when it came to memorizing facts.

    The researchers' report said,“While more notes are beneficial,if the notes are taken mindlessly,as is more likely the case on a laptop,the benefit disappears. ”

    In another experiment aimed at testing long­term memory,students took notes as before but were tested a week after the lecture.This time,the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding,but that they also lead to superior revision in the future.

    In today's working world, the high school diploma program has become the initial footstep in achieving a successful career. A high school diploma is a formal document issued to certify a candidate's successful completion of a prescribed (规定的) secondary school program of studies.

    It takes four years to complete the high school diploma program. The eligibility (合格) requirements for the high school diploma vary from state to state. A high school diploma is the minimum qualification for higher education and government jobs in the United States. The opportunities for a better job are extremely limited for one who has not earned a high school diploma. To be more specific, the high school diploma can qualify one for fruitful careers in science, education, health care, the travel industry, and the legal profession.

    In some states, high school diplomas are differentiated by type such as a general diploma, an academic diploma, or a vocational diploma. A high school diploma is regarded as the minimum admission requirement for post-secondary education programs. When people apply for a green card or a US visa, a high school diploma is a valuable asset for immigrants into the United States.

    There are several ways to achieve a high school diploma. One can get the diploma through traditional classroom study. It is best suited for individuals who enjoy face-to-face interaction with their teachers and classmates. In the United States, opportunities are provided for getting high school diplomas without attending classes at school. One can earn a high school diploma at home through a combination of online and correspondence classes.

    Generally, the high school diploma programs do not have minimum age requirements. In order to get the high school diploma, the students must complete the coursework dictated by their school district. Curriculum (课程) varies from district to district. Before enrollment, a student counseling (咨询) service is recommended to most students.
