老师我问题中的那句句子是根据下面那句话(选自经济学人)中破折号的使用方法写的,我感觉后面的句子出现很出人意料,不了解这句话里面破折号后面的成分是不是是插入语?
The necessary adjustments will not take place while the state pays workers to wait for their old jobs to return—often on better money than they got before.
插入语用逗号和句子隔开,不需要破折号。本句破折号后为对句子中pays workers做的补充说明,是补充语supplement。
