You know what. I signed up for a dance class. I've always wanted to learn how to dance.
你知道嘛,我报了一个舞蹈课程,我一直都想学。
I'm happy for you.
我真为你高兴。
重点讲解:
I enrolled a dance class.
I signed up for a dance class.
报名参加舞蹈班,可以说I enrolled a dance class, enroll有“登记,参加”的意思,但是口语中用这个词表示“报名参加”稍显正式,短语sign up for会更加口语一些,所以这句话还可以表示为I signed up for a dance class.
