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.

For several decades, there has been an organized campaign intended to produce distrust in science, funded by those whose interests are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things, from the structure of the universe to the relativity of time and space.

Stressing successes isn’t wrong, but for many people it’s not persuasive. An alternative answer to the question “Why trust science?” is that scientists use the so-called scientific method. But what is called the scientific method isn’t what scientists actually do. Science is dynamic: new methods get invented; old ones get abandoned; and at any particular point, scientists can be found doing many different things. False theories sometimes lead to true results, so even if an experiment works, it doesn’t prove that the theory it was designed to test is true.

If there is no specific scientific method, then what is the basis for trust in science? The answer is the methods by which those claims are evaluated. A scientific claim is never accepted as true until it has gone through a long process of examination by fellow scientists. Scientists draft the initial version of a paper and then send it to colleagues for suggestions. Until this point, scientific feedback is typically fairly friendly. But the next step is different: the revised paper is submitted to a scientific journal, where things get a whole lot tougher. Editors deliberately send scientific papers to people who are not friends or colleagues of the authors, and the job of the reviewer is to find errors or other faults. We call this process “peer review” because the reviewers are scientific peers—experts in the same field—but they act in the role of a superior who has both the right and the responsibility to find fault. It is only after the reviewers and the editor are satisfied that any problems have been fixed that the paper will be printed in the journal and enters the body of “science.”

Some people argue that we should not trust science because scientists are “always changing their minds.” While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that science produces both creativity and stability. New observations, ideas, explanations and attempts to combine competing claims introduce creativity; transformative questioning leads to collective decisions and the stability of scientific knowledge. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.

1.Scientists stress the success of science in order to ________.

A.promote basic knowledge of science

B.remind people of scientific achievements

C.remove possible doubts about science

D.show their attitude towards the campaign

2.What can we learn about the so-called scientific method?

A.It’s an easy job to prove its existence.

B.It usually agrees with scientists’ ideas.

C.It hardly gets mixed with false theories.

D.It constantly changes and progresses.

3.What can we learn about “peer” review?

A.It seldom gives negative evaluation of a paper.

B.It is usually conducted by unfriendly experts.

C.It aims to perfect the paper to be published.

D.It happens at the beginning of the evaluation process.

4.The underlined sentence in the last paragraph implies that ________.

A.it is not uncommon for science to be overturned

B.scientists are very strong in changing their minds

C.people lose faith in those changeable scientists

D.changes bring creativity and stability to science

For several decades, there has been an extensive and organized campaign intended to generate distrust in science, funded by regulated industries and libertarian think tanks（自由主义智囊团）whose interests and beliefs are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things, from the structure of the universe to the relativity of time and space.

Quoting successes isn’t wrong, but for many people it’s not persuasive. What is typically declared to be the scientific method -- develop a supposition, then design an experiment to test it -- isn’t what scientists actually do. Science is active so that new methods get invented and old ones get abandoned. The scientific method doesn’t always work. False theories can produce true results, so even if an experiment works, it doesn’t prove that the theory it was designed to test it true.

If there is no identifiable scientific method, then what is the guarantee for trust in science?

The answer is the methods by which those claims are evaluated. A scientific claim is never accepted as true until it has gone through a long process of examination by fellow scientists. Until this point, scientific feedback is typically fairly friendly. But the next step is different: once the paper is ready, it is presented to a scientific journal, where things get a whole lot tougher. Editors deliberately send scientific papers to people who are not friends or colleagues of the authors, and the job of the reviewer is to find errors or other inadequacies. We call this process “peer review” because the reviewers are scientific peers but they act in the role of a superior who has both the right and the obligation to find fault. It is only after the reviewers and the editor are satisfied that any problems have been fixed that the paper is accepted for publication and enters the body of “science.”

Does this process ever go wrong? Of course. Scientists are human. But if we look carefully at historical cases where science went wrong, typically there was no agreement reached by all. Some people argue that we should not trust science because scientists are “always changing their minds.” While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that it explains what might otherwise appear paradoxical（矛盾的）: that science produces both novelty（新颖性）and stability. New observations, ideas, interpretations introduce novelty: trans-formative questioning leads to collective decisions and the stability of scientific knowledge. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.

1.Distrust in science has been found because _________.

A.scientists’ citing successes isn’t persuasive for many people to some extent

B.most scientists have tended to lay too much emphasis on the success of science

C.a wide - ranging and organized campaign has been founded in some industries and think tanks

D.someone’s benefits and beliefs are endangered by the findings of modern science

2.Which of the following statements will the author agree with about a scientific method?

A.A scientific method doesn’t necessarily take effect because science is changing.

B.A scientific method is not right because it isn’t what scientists actually do.

C.A successful experiment can guarantee the truthfulness of a claim by a scientific method.

D.True theories can produce false results because the scientific method doesn’t work.

3.What purpose does “peer review” in evaluating a scientific claim mainly serve?

A.The scientific claim can be completely accepted by the reviewers in the same field.

B.The scientific peers can draw right conclusions by finding its faults or other inadequacies.

C.The scientific claim can be published and recognized as true in science.

D.The scientific paper can be successfully submitted to a scientific journal.

4.It can be inferred from the last paragraph that _________.

A.Not all the claims about the falsehood of well-established science lead to its being overturned

B.It is inevitable that science sometimes goes wrong because it appears paradoxical

C.The beauty of science lies in the paradox of being both novel and stable

D.Science is not trustful because scientists always change their minds.

For several decades, there has been an extensive and organized campaign intended to generate distrust in science, funded by those whose interests and ideologies are threatened by the findings of modern science. In response, scientists have tended to stress the success of science. After all, scientists have been right about most things.

Stressing successes isn’t wrong, but for many people it’s not persuasive. An alternative answer to the question “Why trust science?” is that scientists use the so-called scientific method. If you’ve got a high school science textbook lying around, you’ll probably find that answer in it. But what is typically thought to be the scientific method — develop a hypothesis (假设), then design an experiment to test it — isn’t what scientists actually do. Science is dynamic: new methods get invented; old ones get abandoned; and sometimes, scientists can be found doing many different things.

If there is no identifiable scientific method, then what is the reason for trust in science? The answer is how those claims are evaluated. The common element in modern science, regardless of the specific field or the particular methods being used, is the strict scrutiny (审查) of claims. It’s this tough, sustained process that works to make sure faulty claims are rejected. A scientific claim is never accepted as true until it has gone through a lengthy “peer review” because the reviewers are experts in the same field who have both the right and the obligation (责任) to find faults.

A key aspect of scientific judgment is that it is done collectively. No claim gets accepted until it has been vetted by dozens, if not hundreds, of heads. In areas that have been contested, like climate science and vaccine safety, it’s thousands. This is why we are generally justified in not worrying too much if a single scientist, even a very famous one, disagrees with the claim. And this is why diversity in science — the more people looking at a claim from different angles — is important.

Does this process ever go wrong? Of course. Scientists are humans. There is always the possibility of revising a claim on the basis of new evidence. Some people argue that we should not trust science because scientists are “always changing their minds.” While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that it explains what might otherwise appear paradoxical (矛盾的): that science produces both novelty and stability. Scientists do change their minds in the face of new evidence, but this is a strength of science, not a weakness.

1.How does the author think of the scientific method?

A.Stable. B.Persuasive.

C.Unreliable. D.Unrealistic.

2.What does the underlined word “vetted” in Paragraph 4 probably mean?

A.Explained. B.Examined.

C.Repeated. D.Released.

3.According to the passage, the author may agree that ______.

A.it is not persuasive to reject those faulty claims

B.settled science tends to be collectively overturned

C.a leading expert cannot play a decisive role in a scrutiny

D.diversity in knowledge is the common element in science

4.Which of the following would be the best title for the passage?

A.Put Your Faith in Science B.Defend the Truth in Science

A gentleman put an advertisement in a newspaper for a boy to work in his office. Out of the nearly fifty men who came to apply, the man selected one and dismissed(解散) the others.

“I should like to know,” said a friend, “the reason you preferred that boy, who brough not a single letter—not a recommendation(介绍信）.”

“You are wrong,” said the gentleman. He had a great many. He wiped his feet at the door and closed the door after him, indicating that he was careful. He gave his seat immediately to the crippled (跛的) old man, showing that he was kind and thoughtful. He took off his cap when he came in and answered my questions immediately, showing that he was polite and gentlemanly.

“All the rest stepped over the book which I had purposely put on the floor. He picked it up and placed it on the table; and he waited quietly for his turn instead of pushing and crowding.

When I talked to him, I noticed his tidy clothing, his neatly brushed hair, and his clean fingernails(指甲). Can’t you see that these things are excellent recommendations? I consider them more significant(明显的) than letters.”

Postmen are all too used to keeping an eye out for the threat of dogs. But in a seaside town in North Wales，they have been forced to take cover from an unexpected threat seagulls. They have complained that the birds have become so terrifying that deliveries to some streets have been suspended. Yesterday residents of Abergele agreed the seagulls were fearless but said they were angry at losing their daily post.

Roberts, who works as a safety adviser，lives where the attacks have taken place. “Last week，we noticed we hadn’t got any mail for what we thought was a week，but it’s hard to tell because you don’t always know if you’re due any mail，”she said. “We put something on　 Facebook asking if anyone else had not had their post. . . One of my Facebook friends said a postman had refused to deliver because of the seagulls. ”

Royal Mail said that deliveries had been interrupted because of the postman experiencing attacks by seagulls as he delivered mail on his round there over the past few weeks, adding that the postman got people’s mail through whenever it was safe.

“We know that these kinds of attacks do happen at this time of year across the country as they are nesting，’’she said. Royal Mail apologized to the customers affected and promised to continue to monitor the situation every day，but in the meantime some are having to travel to neighbouring Rhyl to collect mail from the delivery office there. But he recommends preventing gulls nesting on roofs in advance by putting up nets, and if all else fails, walking with an umbrella up during worst-affected areas.
