For weeks, Facebook has been questioned about its role in spreading fake news.

幾個星期以來，Facebook一直因其在假資訊傳播過程中扮演的角色而遭到質疑。

Now the company has mounted its most concerted effort to combat the problem.

目前，該公司正采取步調最為一致的行動來解決這一問題。

Facebook said Thursday it had begun a series of experiments to limit misinformation on its site.

Facebook周四表示，公司已經著手推進一系列試驗性舉措，旨在遏制其網站上虛假信息的傳播。

The tests include making it easier for its 1.8 billion members to report fake news, and creating partnerships with outside fact-checking organizations to help it indicate when articles are false.

這些試驗包括：讓其18億名用戶可以更加容易地舉報假資訊，并與外部事實核查機構建立合作關系，以便及時就內容虛假的文章做出提示。

The company is also changing some advertising practices to stop purveyors of fake news from profiting from it.

此外，該公司正在改變某些廣告業務慣例，為的是防止假資訊供應者從中獲利。

Facebook is in a tricky position with these tests.

開展這些試驗的Facebook處境頗為尷尬。

It has regarded itself as a neutral place where people can freely post, read and view content.

But as its reach and influence have grown, it has had to confront questions about its moral obligations and ethical standards regarding what appears on the network.

但隨著它的傳播范圍和影響力與日俱增，它不得不面對與出現在其網站的信息有關的道德義務和倫理標準問題。

Its experiments on curtailing fake news show that Facebook recognizes it has a deepening responsibility for what is on its site.

But Facebook is wary of exposing itself to claims of censorship.
