African swine fever has wiped out a third of China's pig population. Now government officials are discussing dramatic steps to stabilize the world’s largest pork market. Pork is a huge deal in China. The country is home to half of all the pigs on the planet .The meat is a staple of the Chinese diet, which means its scarcity could damage China's social stability. The outbreak of swine fever also threatens the global pork supply chain.
While Chinese authorities have already made plans to support the pig farms and families who may struggle with soaring prices, they re stepping up efforts to deal with the crisis.
The price sellers pay for pork has risen nearly 70% in the last year. And the average price that distributors pay suppliers was up 90% in the last week of August compared to a year ago, according to government data. Analysts say prices could yet go even higher.
The government on Wednesday announced more measures to encourage pig farmers and producers to breed more baby pigs. But they may need to go even further to fill the gap. Authorities have promised to release the government's emergency reserves of frozen pig meat if necessary. Ministry of Commerce spokesman Gao Feng said last week that the agency will “closely monitor market developments” before it makes such a decision.
It's difficult to overstate the scale of the problem. As of July, China had lost more than 100 million pigs in the last year, according to the data released Tuesday by the country’s agricultural ministry. Part of the problem is that farmers aren’t refilling their pig farms after the sick animals die, according to China’s agricultural ministry. That has pressured Chinese authorities to explore ways to encourage farmers and producers to breed more baby pigs. The finance and agricultural ministries on Wednesday asked local governments to free up money that could be used for artificial insemination (人工授精) technology.
The ministries also called on local officials to accelerate the distribution of subsidies (补贴) to farms where pigs have been killed because of sickness. And the Beijing government plans to increase loan support and insurance coverage for pig producers nationwide.
1.What is the possible consequence of the reduction in China’s pig population?
A.A lack of diversity of meat.
B.Dramatic drop in the pork price.
C.Instability of the Chinese society.
D.The boom of global pork supply chain.
2.Which is a measure of the government to address the problem?
A.To release the emergency reserves of fresh meat.
B.To fund artificial insemination technology.
C.To offer free loan support to pig farmers.
D.To limit the pork price at the market.
3.What can be inferred from Paragraph 5?
A.China has lost a large majority of its pigs.
B.The swine problem is not that serious at present.
C.Farmers are unwilling to raise more pigs for fear of further loss.
D.The problem can surely be solved by future technological advance.
4.What is the main idea of the passage?
A.Swine fever threatened the pork supply in the world.
B.China makes efforts to solve the swine problem.
C.China is home to half of all the pigs on the planet.
D.Chinese authorities encourage farmers to breed more baby pigs.

高三英语单项填空中等难度题查看答案及解析
Late blight (晚疫病) is a common disease of plants such as tomatoes and potatoes, capable of wiping out entire crops on commercial-sized fields. If conditions are favorable, it can quickly spread to other plants through wet soil and wind.
In history, late blight caused over 1 million deaths in Ireland. Today it still causes more than 6.7 billion dollars in annual losses worldwide. Small farms and growers are often the hardest hit, many stating losing almost two-thirds of their yearly production, because usually they don’t have money to identify and treat the disease.
But farmers may have a new weapon now. The technology, designed by researchers at North Carolina State University can recognize sick plants early by employing a piece of test paper that plugs into (接入) a reader on a smartphone.
Plants produce signaling chemicals from their leaves. “If a plant is diseased, the type and concentration of these chemicals changes,” said Wei Qingshan, an engineer at North Carolina State University. If the farmer suspects a late blight infection is underway, he can remove a leaf from a living plant and place it in a small, covered glass jar. After the leaf’s volatile (挥发性的) chemicals have accumulated for 15 minutes or so, the cap is removed and the air is pumped from the jar into a reader attached to the back of a smartphone. Inside the smartphone reader is a piece of paper specially treated with dyes (染料) by the researchers. Upon interacting (相互作用) with the plant’s volatile chemicals, the paper changes color to indicate the presence or absence of the late blight.
The researchers hope to tailor the technology for other crop diseases, which continue to appear as climate change and global trade increase the stress on agricultural systems. “This is an important step in the improvement of global food security,” Wei Qingshan said.
1.What are the statistics in Paragraph 2 mainly about?
A.The damage caused by late blight.
B.The money put into late blight treatment.
C.The number of crops in a commercial-sized field.
D.The yearly production of small farms and growers.
2.According to Wei Qingshan, how would a farmer find out if a plant was infected?
A.By treating the plant with special dyes.
B.By putting volatile chemicals on the plant.
C.By testing the air in the jar with a leaf inside.
D.By examining the land with a smartphone reader.
3.What do the researchers expect of their new technology?
A.It’ll reach farmers soon.
B.It’ll get rid of late blight.
C.It’ll be beneficial to the climate.
D.It’ll be able to detect more crop diseases.
4.What is the purpose of this passage?
A.To introduce a test method of late blight.
B.To explain the causes of late blight.
C.To discuss the effects of late blight.
D.To tell the history of late blight.

For almost 500 years, people have wondered what deadly disease wiped out most of the Aztecs (阿芝特克人）. The locals called it cocolizthi, and now a team of scientists think they know exactly what that was. The outbreak is considered to be one of the deadliest epidemics (传染病）in human history. For centuries, its cause has been debated by historians. New evidence suggests that the Aztecs died from a type of bacteria called salmonella enterica.
An international team of scientists came to this conclusion after analysing the skeletons (骨骼) of 29 Aztecs buried in a cocoliztli cemetery in the Oaxaca region of Mexico. The scientists obtained samples from the teeth of ten of the skeletons. They compared these with their database of bacteria and found traces of salmonella enterica.
Salmonella enterica can cause enteric fever, of which typhoid (伤寒）is a type. Today, there are around 21 million cases of typhoid worldwide and it is considered a global threat.
The Aztecs were fierce hunter-gatherers who settled in what is now Mexico at the beginning of the 13th century. From their incredible capital city Tenochtitlan(now Mexico City),the Aztecs fought wars with other tribes until they ruled much of the region.
The Aztecs ended up controlling large parts of Mesoamerica--now much of Mexico and Central America--until Spanish explorers arrived in 1519 and brought with them advanced weapons and deadly diseases. The team believe that the domesticated animals, such as goats and horses, which the explorers brought with them carried the deadly bacteria.
By 1545,not even 30 years after the Spanish had arrived, Mexico's Aztec nation started coming down with a terrible illness. Symptoms included high fever, headaches and bleeding from the eyes, nose and mouth. Within five years, up to 15 million people---more than 80%of the population at the time--had died from the mystery illness they called cocoliztli. The Aztec people had no immunity (免疫) to fight the disease.
“We cannot say with certainty that salmonella enterica was the cause of the cocolizti epidemic,” said Kirsten Bos from the Max Planck Institute for the Science of Human History in Germany.” We do believe that it should be considered a strong candidate."
1.Which helped the scientists come to the conclusion.
A.Certain traces of deadly diseases carried by goats and horses
B.Extensive comparison of Aztecs buried in a cocoliztli cemetery
C.Definite discoveries of infected tooth samples from the database
D.Small amounts of certain bacteria in the teeth of the skeletons
2.Which of the following is TRUE about the Aztecs?
A.They had a population of about 15 million around 1545.
B.Their livelihood depended on raising domesticated animals.
C.Their population dropped sharply in the middle 16th century.
D.They won the wars with the Spanish despite being poorly equipped.
3.The underlined word “it” in the last paragraph refers to_
A.cocolizti epidemic B.salmonella enterica C.the typhoid D.the Max Planck Institute
4.The passage is mainly about
A.how the Aztecs got infected with salmonella enterica
B.why the Aztecs had no immunity to fight typhoid
C.which reason caused the Aztecs to abandon their native land
D.what led to the military and economic decline of the Aztecs
