英语翻译
At the bench Howl worked a good deal harder and faster than Michael,putting spells together in an expert but slapdash way.
expert在这里怎么翻译?

由后面的并列词 【slapdash adj.匆促的；草率的；粗心的,马虎的】可知,这里的expert由于与后面的词一起用在短语 in an expert but slapdash way 之中,因此,都应该是【形容词】.
expert
adj.
熟练的；内行的；老练的所以,在这里expert意思应该是：熟练的；内行的；老练的. in an expert but slapdash way ：以熟练而匆促的方式.祝你开心如意!
