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.

If you struggled to get up for work on Wednesdays, there could be a good reason--it is the day our mood reaches its lowest point. Monday has traditionally been thought of as the most depressing day of the week but according to psychologists, midweek gives more cause for concern in reality. Wednesday represented the lowest point in the week as people were furthest away from the weekend that has either just gone or is coming up and often feel too tired to go on with work.

However, psychologists have found that, on average, people's moods remain about the same on each day throughout the week.

To start their research, the University of Sydney scientists asked around 200 people what they thought their mood would be on each day of the week.

Most said their worst moods were on Monday mornings and evenings but they became increasingly cheerful as the week went on, with their best moods falling on Friday and Saturday mornings and evenings.

When asked why they believed that Friday and Saturday were best, respondents said they saw them as less-structured days when they could choose how to spend their time.

The psychologists then asked a further 350 people how they felt each day.

They found that, on average, people's moods remained about the same on each day throughout the week.Mondays were not as depressing as they had feared and Fridays and Saturdays were not as exciting as predicted.

Professor Charles Areni, who led the study, said the day-of-the-week stereotypes (陈词滥调) stem from a cultural belief that people are generally happier when they are free to choose their activities compared to when they are engaged in paid work.

In reality, he said, weekends do not often see moods change because they are frequently dominated by productive activities that may require large amounts of energy and begin to feel tired like work. "Day-of-the-week stereotypes like Monday morning blues and Thank God It's Friday are largely illusions," he said.

1. _________ has always been thought as the unhappiest day of a week.

A. Monday                 B. Wednesday                    C. Friday                     D. Sunday

2.People don’t like Wednesday because ________.

A. work seems to be endless on Wednesday

B. it is the most-structured day of a week

C. they have just had their weekend

D. weekend is still a couple of days’ away

3. Which of the following is the finding of the research mentioned in the passage?

A. All of the people asked admitted that on Monday they had the worst moods.

B. Saturday and Sunday were the best because people could plan their time freely.

C. There was no sharp difference in people’s moods between each day of the week.

D. Different people had different ideas about which day was the worst in a week.

4. Charles Areni believes that the day-of-the-week stereotypes results from________.

A. the productive activities requiring a large amount of energy

B. the cultural belief that doing paid work is usually less pleasant than doing freely chosen work

C. the illusions of day-of-the-week stereotypes

D. the days in a week when our mood reaches its lowest points

It is generally agreed that a good student must be able to concentrate for a reasonable time on a written text, yet most students are given very little help to practice this skill.

Generations of Americans have been brought up to believe that a good breakfast is essential to one's life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.

But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn’t have breakfast increased by 33%—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America.

For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting breakfast. “Going without breakfast does not affect work,” said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, “nor does giving people breakfast improve work.”

Scientific evidence linking breakfast to better health or better work is surprisingly inadequate, and most of the recent work involves children, not grown-ups. “The literature,” says one researcher,  Dr Earnest Polite at the University of Texas, “is poor.”

1.The main idea of the passage is that _______.

2.For those who do not take breakfast, the good news is that _______.

3.The underlined part “nor does giving people breakfast improve work” means  _______.

4.The word "literature" in the last sentence refers to _______.

5.What is implied but not stated by the author is that _______.
