总部位于瑞士日内瓦的世界经济论坛周一宣布，由于当前新冠疫情的不确定性，将取消原定于8月在新加坡举行的特别年会。

The World Economic Forum (WEF) has canceled its annual meeting — the blue-ribbon event for the global elite to discuss the world’s problems — due to be held in Singapore this year, the organizers said late Monday.

The COVID-19 pandemic meant it was not possible to hold such a large event as planned Aug. 17-20, they said.

“Regretfully, the tragic circumstances unfolding across geographies, an uncertain travel outlook, differing speeds of vaccination roll-out and the uncertainty around new variants combine to make it impossible to realize a global meeting with business, government and civil society leaders from all over the world at the scale which was planned,” the WEF said in a statement.

报道中的blue-ribbon就是“一流的，顶级的”。例如：

This is a blue-ribbon pie — I never knew pecan pie could taste so good!

这个馅饼味道一流，我没想到山核桃馅饼会这么好吃！
