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.

It would be pleasant to believe that all young girls in the past got married for romantic reasons; but the fact is that many of them regarded marriage as their only chance to gain independence from their parents, to have a provider, or to be assured of a good place in society. A couple of generations ago, an old maid of twenty-five did not have much to look forward to, she was more or less fated to remain with her parents or to live in some relative’s home where she would help with the chores and the children. Not so any more. In the first place, women remain young much longer than they used to, and an unmarried woman of twenty-eight or thirty does not feel that her life is over. Besides, since she is probably working and supporting herself, she is free to marry only when and if she chooses. As a result, today’s women tend(倾向) to marry later in life. They have fewer children-or none at all—if they prefer to devote themselves to their profession. The result is a decline in the birthrate.

The new role that women have developed for themselves has changed family life. Children are raised differently; they spend more time with adults who are not their parents: baby sitters, day-care center personnel, relatives, or neighbors. Whether they gain or lose in the process is a hotly debated question. Some child experts believe that young children must spend all their time with their mother if they are to grow sound in body and mind. Others think that children get more from a mother who spends with them “quality time” (a time of fun and relaxation set aside for them) rather than hours of forced and unhappy baby sitting. And many child psychologists point out that children kept in day-care centers every day are brighter than those raised at home. No matter what it is, one thing about child-raising to be certain of is that the longer the child is with the mother, the better.

1.It can be concluded from the passage that______.

A. women today have developed a new role in family life

B. the birthrate is declining as a result of women’s pursuit (追求) of careers

C. women have always been dependent on their parents even after marriage

D. children must spend all their time with their mother if they are to grow sound

2.The change in women’s attitude towards marriage results in all of the following EXCEPT _________.

A. more and more women quit (leave) jobs to take care of their children at home

B. women today tend to marry later than they did

C. women have less time to raise children

D. more and more families remain childless

3.People have different opinions over the question as to______.

A. how children should be raised

B. where children should be raised

C. whether children should stay with their parents

D. how long children should stay with their parents

4.The author suggests that______.

A. working women should not have children

B. children should be kept in day-care centers all the time

C. young children should stay with their mother as long as possible

D. women should leave their work to look after their children at home
