The reason why science exists is to improve our lives. Sometimes science can ruin our small guilty pleasures we nature to be happier, though. These four little truths are just some of those.

Sleeping with pets is a good way to catch the plague(瘟疫), or some other bacterial infections, as is claimed in the study done in February 2011 in Emerging Infectious Diseases magazine. The study shares a case of a nine-year-old boy whose cat caught the plague and gave it to its owners while they were sharing a bed. A regular visit to the vet can greatly reduce the risk of your pet catching any disease that may infect the owner as well.

A recent study done on 200,000 people has shown that vitamin supplements do nothing to improve our lives, and what is worse—they actively increase our death risk. This conclusion from 2010 was so unbelievable that it made researchers do even more studies. Each study had the same result. People who choose vitamin supplements over fruit and vegetables are the same as people who choose to eat a burger over a healthy salad.

People who use the solarium(日光浴室)experience certain changes to their brains that are very similar to many caused by drug addiction. According to a study, our brain can in fact recognize the difference between the natural UV light and the solarium.

Long exposure to artificial light during the night is directly linked to a higher risk of breast cancer, obesity and depression. Exposure to artificial light before sleeping disturbs the natural biorhythms(生物节奏)of our bodies, which leads to restriction on the hormone(荷尔蒙)melatonin, which is the hormone that helps us fall asleep.

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.
