Until recently most historians spoke very critically of the Industrial Revolution.
until词性为连词或介词,recently为副词,until recently, 在词性/语法上如何理解?
在英语中,有些副词可以作某些介词的宾语。例如:
It’s too hot in here. 这里太热了。(摘自龚亚夫主编:《新编高中英语语法》普及版p.129)
I looked everywhere except there. 除了那儿,我到处都看过了。(同上)
I don’t know it until recently. 直到最近我才知道它。(同上)
