综合类考试：阅读理解重点内容encyclopedia
Wikipedia， the famous online encyclopedia， is looking to impose morediscipline with new restrictions on the editing of articles.
The latest changes come as Wikipedia tries to balance a need for credibility and a desire for openness.
While anyone can still edit entries， the site is testing pages that wont register changes until they are approved by an experienced Wikipedia editor.
If the sites users respond well to the test run， the new restrictions will apply to all entries for living people in the next few weeks.
The idea is to block the kind of high-profile vandalism that has marred some pages.
In one of the most recent embarrassments， US Democratic Senators Robert Byrd was prematurely declared dead by rogue editors.
Still， Wikipedia risks discouraging legitimate editing if restrictions on changes or additions become too burdensome， keeping articles from getting better or keeping up with events. That may be especially true on more obscure pages with fewer active volunteers to approve edits timely.
Aware of the risks， Wikipedia ha s set the criteria for "experienced editor" status relatively low. Users who are registered for a few days can give changes the OK， said Jay Walsh， a spokesman for the nonprofit
Wikimedia Foundation， which runs the site.
A more uniform system for filtering changes on Wikipedia represents a step back from the sites original philosophy， which called for harnessing the collective knowledge of volunteer editors without any major restrictions.
But it is not the first time Wikipedia has attached some strings.
The same flagging process， for example， has been imposed on all entries in the German-language Wikipedia for more than a year.
On the English site， too， high， profile pages that are likely to be defaced， such as Michael Jacksons， have been tightly restricted.
Some observers believe Wikipedia must continue tightening editing policies if it wants to gain credibility.
"Im just waiting for the other shoe to drop，" said Erie Goldman， director of the High Tech Law Institute at the Santa Clara University School of Law.
Goldman envisions a future Wikipedia crated by a relatively small group of dedicated editors. Under the current model， he said， there simply arent enough volunteers to catch all errors.
