高三英语单项填空简单题查看答案及解析

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.
