Panic Buying

Shoppers around the world are crazy buying because of fears over the coronavirus(新型冠状病毒), which caused a critical plague in China and even other countries at the beginning of 2020. People in countries such as England, Japan, Singapore and Australia have been emptying supermarket shelves of toilet paper, face masks, hand wash products and dried and canned food. Photos and videos of shoppers in Australia quarreling over the last pack of toilet roll in a supermarket have spread across social media swiftly.

However, governments have advised their citizens that there is no need to “panic buy”. They added that panic buying would only reduce the supply of products needed by patients and medical staff, which could exacerbate the problems the COVID-19 virus is causing. Singapore's prime minister comforted Singaporeans that: “We have enough supplies. There's no need to stock up.” A week after the panic buying fever, things have calmed down and shoppers have gone back to purchasing items in normal quantities.

Psychologists say panic buying is an “unwise” behaviour that is part of a condition called FOMO - the fear of missing out. Dr. Katharina Wittgens said a herd mentality(从众心理) sets in during disasters that causes people to copy the actions of others. People watch the news of items being bought in quantity and immediately rush out to the stores to do the same. She said people were taking on too much the risks of dying from the coronavirus. She said: “Far more people die in car accidents or household accidents per year but we don't panic about these things in the morning before we go to work.”

1.What made shoppers in different countries crazy buying?

A.The approach of 2020 New Year’s Day.

B.The shortage of resources and supplies in their nations.

C.Their concern about the virus.

D.The discount from supermarkets.

2.What does the underlined word in Paragraph 2 refer to?

A.solve B.release C.worsen D.quicken

3.What is the reason for this behavior according to expert?

A.People tend to follow others’ actions in the period of disaster.

B.People are wiser in making decisions.

C.People think no one needs the supplies.

D.People do not believe what others said.

4.What can be concluded from the last paragraph?

A.People should not panic over the virus.

B.More people die from car accidents.

C.People buy little when they go to the stores.

D.We should panic about the situation.

Travel Unaccompanie

Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen. It is challenging. This is what drives young people to travel alone.It is seen as character building and a chance to prove that they can make it on their own.

Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He said he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old.

Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that was ready to deal with anything”. He said, “The feeling of having conquered something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

The great 19th century explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

1.Which of the following will Kristina Wegscheider agree with?

A. Traveling alone is a necessary experience for everyone.

B. It is more meaningful to travel in foreign countries.

C. It is comfortable to travel around without a friend.

D. Traveling abroad helps people to find new things.

2.Traveling alone is challenging because__________.

A. it will finally build your character

B. you have to make things on your own

C. you depend on yourself whatever happens

D. it is hard for you to prove yourself to others

3.What can we infer about Chris Richardson?

A. He started traveling at an early age.

B. He was once shot in the arm.

C. His website inspires others a lot.

D. He used to work as a salesman.

高三英语阅读理解中等难度题查看答案及解析

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

There is growing concern about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle for families in many countries.

Three UN agencies have published a report recently, saying high prices are likely to continue. Gregory Barrow, who is with the World Food Program in Rome, says, “If you look at the places where the World Food Program works, particularly in developing countries, you see people who might be spending more than 60 percent of their salary in purchasing food for their families.”

East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, mostly in the north. Yet food is going to waste in central Kenya. Now, farmers there want the government to buy their food and give it to those in need. Farmers say bad roads and lack of transportation make it difficult for them to get their produce to the market.

Mr. Barrow says, “It needs the government to make some arrangements such as providing transport. They can buy it at a good price, then give it to those people instead of asking for food from overseas, which is very bad. When we are throwing away food, they are asking for food from overseas.”

Economists say that imports reduce local food prices, decrease productivity(生产效率) and increase the dependency on other countries. Farmers in Kenya hope the government can pay higher prices for their crops so that they can feed more Kenyans.

1.What is the best title for this passage?

A. Kenya Imports Food from Abroad

B. A World Food Program in Rome.

C. The Poor Suffer from High Food Prices.

D. A Report Published by Three UN Agencies.

2.What do we know about Kenya from the passage?

A. The people in central Kenya are suffering from hunger.

B. At least three and a half million Kenyans lack food.

C. The Kenyan government wants to improve road conditions.

D. People in northern Kenya refuse to ask for food from overseas.

3.What does “they” in the fourth paragraph refer to?

A. The people of northern Kenya.

B. Government officials.

C. The farmers of central Kenya.

D. Kenyan economists.

4.Which of the following statements is TRUE, according to this passage?

A. Gregory Barrow suggests that Kenya make good use of overseas food.

B. People in northern Kenya are suffering the drought less than the central.

C. Economists believe importing food from abroad may cause problems.

D. Kenyan government hopes to buy the native crops at higher prices.
