在数月前由国家有关部门举办的一次大型科普展中，有一个别具匠心的设计：三扇门上各有一个问题：“污染环境的是谁？”“饱受环境恶化之苦的是谁？”“保护环境的是谁？”拉开门，里面各是一面镜子，照出的是参观者自己。

根据下列文章，回答26～30题。It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the authors names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.
No longer. The Internet and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it- is making access to scientific results a reality. The Organization for Economic Co-operation and Development （OECD） has just issued a report describing the far-reaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.
The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market is estimated at between $7 billion and $11 billion. The International Association of Scientific, Technical and Medical Publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals.
This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three main institutional subscribers pay for access to a collection of online journal titles through site-licensing agreements. There is open-access publishing, typically supported by asking the author （or his employer） to pay for the paper to be published. Finally, there are open-access archives, where organizations such as universities or international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form. of the peer-review process, at least for the publication of papers.
