It Is Never Too Early to Think—and Communicate—like a Scientist
Who is a scientist and what is his job? A chemist doing experiments? A geologist out studying rocks? When most people think about science, they imagine characters making discoveries or finding cures （治疗方法）for new diseases. However, these leave out an extremely important part of the scientific process: communicating—sharing the results of that work.
Imagine if someone discovered something important about a disease. Other scientists need to understand the work well enough to use these new developments to make even more discoveries in the future. The public, too, needs to understand how these discoveries might influence their lives. But none of this will be possible if the work is not shared. Being a scientist goes far beyond the moment of discovery.
Without clear communication, scientists would not be able to use the work that has already been done. So how do scientists tell others about the work that they have done? How do they make sure that everything that they share is as clear and correct as possible?
Researchers publish their work in scientific journals（期刊）.These journals can be read by other researchers around the world. It is very important for these journals, and for the scientists who read them, to make sure that the research included is as correct as possible. In order to do that, articles given to scientific journals before publication first go through a process called peer review. Other scientists who do research in areas related to the work in an article are asked to read through it. Scientists also provide feedback to the writers. They bring up new questions the writer may not have considered, recognize limitations to the results being described, and also make sure that no mistakes were made during the process.
Frontiers for Young Minds is a scientific journal written for—and reviewed by young people. All of the articles in it are based on works already published in a peer reviewed scientific journal. However, while scientists are good at making sure that articles are understandable for other scientists, there are no better experts to make sure that something can be understood by young people than the young people themselves. By working together with an experts young reviewers read the article to see if any part of the article is hard to understands make it clear why the experiment was done in the way it was done and check whether the figures （数据）clearly explain the point of the article.
Basically, these young reviewers learn to think like scientists. It is never too early to start! Ask questions, learn new things, and don't forget the importance of communicating your findings.
1.What is Paragraph 2 mainly about?
A.What is required to be a good scientist.
B.Who should understand a scientist’s job.
C.Why sharing the results of scientific work is important.
D.How scientists make sure their work is clear and correct.
2.From the passage we can know that________.
A.scientists are good at working together with others
B.young people usually enjoy reading scientific journals
C.in peer review, other scientists bring up questions to readers
D.young reviewers help make articles in Frontiers for Young Minds more readable
3.What is the writer's main purpose in writing this passage?
A.To introduce how scientists do their jobs.
B.To offer practical advice on how to ask scientific questions.
C.To explain the effects of peer review on scientific journals.
D.To encourage young people to think and communicate like scientists.
