Siberias forests are being logged at an incredible rate.
假如表被动的话，不是可以直接无需being吗？
Siberias forests are logged at an incredible rate.
该句为目前进行时的被动语态。意为“西伯利亚的森林正在以惊人的速度被砍伐。”
去掉 being 也可以，那是一般目前时的被动语态，意思就变了。
are being logged 是“正在被砍伐”。
are logged 是“常常被砍伐”。（该森林被砍伐是正常状态）
看来，网友需要认真学习一下被动语态的入门知识了。
目前进行时的被动语态：am/is/are + being + 过去分词
The thief is being questioned in the next room. 那个小偷正在隔壁房间同意审问。
Is the car accident being looked into now? 那起交通事故正在被调查吗？
过去进行时的被动语态：was/were+being + 过去分词
When I called,tea was being served. 当我打电话时，正值上茶之际。
