There is good reason to believe that emerging digital technologies can improve the functioning of agriculture markets at a very low cost per farmer.

Mobile phones, particularly GPS-enabled smartphones, make the provision of tailored information much easier than before. Recommendations for agrochemical inputs that address specific soil conditions can improve yields while reducing environmentally harmful and wasteful use. Farmers can tailor their investment decisions to expected weather patterns and benefit from improvements in weather forecasting. As smartphone use continues to expand, farmers will increasingly have the means to watch videos demonstrating new agricultural techniques or take pictures of pests affecting their crops and either request automatic identification and recommendations or raise questions with agronomists. Finally, digital agricultural services can improve the functioning of agricultural supply chains. For example, these services could make it easier for farmers to check and compare input or output prices ; and facilitate coordination among farmers in an area and with traders.

However, despite the potential of digital agriculture, reasons for skepticism remain. Overcoming informational restrictions may not result in substantially increased agricultural productivity, given the existence of other barriers such as input shortages at local markets, and missing insurance markets. Informational barriers are also important, and mobile phone messages may not overcome them: some farmers ignore messages, especially from unknown sources. Some farmers are illiterate and have difficulty using voice menus. Senders may design obscure and confusing messages or may provide messages designed to target objectives at odds with farmer interests. Effective communication may require pictures or video. Smartphones are thus required to receive these messages, but few farmers currently have access to this technology in the poorest countries. Finally, farmers may begin to ignore reminders they are repeated too often, or they may be annoyed by unwanted messages,　 which could lead to reduced trust in the messaging system.

1.According to Para 2, what can farmers do in digital agriculture?

A.They can use agrochemical to handle environmental problems.

B.They can adjust investment decisions based on weather forecasts.

C.They can identify pests on their crops by watching videos.

D.They can compete with others in prices in an efficient way.

2.What does the underlined phrase“at odds with”in the last paragraph mean?

A.In disagreement with. B.By means of.

C.In line with. D.Apart from.

3.Which of the following is NOT considered as an informational barrier?

A.Shortages of input in local markets and lack of insurance markets.

B.No access to digital technology in poorest countries.

C.Failure to read or use the voice menu on mobile phones.

D.Loss of interest and ignorance of the intended messages.

4.What is the author’s attitude towards digital agriculture?

A.Supportive. B.Doubtful. C.Objective. D.Negative.

Christopher Warnock, chief executive of E-Brary, believes most consumers won't want to buy entire books, only the parts that interest them．

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably(必然地) associated with environmental damage.

Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product（GDP）. Before growth is calculated, inflation （通货膨胀） is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.

There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.

Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.

In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable（必然的，不可避免的）. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.

For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.

1.What does the passage mainly talk about?

A. Pollution caused by plant construction

B. Effects of windmills on the environment

C. Economic growth and human civilization

D. Economic growth and environmental damage

2.What does the underlined word "They" in the third paragraph refer to?

A. Goods and products　　 B. The industrial plants

C. Water and atmosphere　 D. Negative health effects

3.According to the passage, the author holds the opinion that ____.

A. economic growth should be calculated in terms of GDP

B. use of natural resources causes no damage to the environment

C. industrial manufacturing may cause damage to the environment

D. a windmill is a perfect way to produce economically practical energy

4.Which of the following shows the structure of the passage?
