请教老师,这句话:The referee heard the gibes from the crowd, but,
ever the professional, ignored them.中ever the professional该如何理解呢,ever这里是副词么,和后面的 the professional语义上是什么关系呢?谢谢老师解答?
However, this was
only the case when participants watched the films with the curtain between them
open.这句话最后的between
them 还有open都是修饰curtain的吧?with加名词用法?
