英语句型不懂

问题描述:

英语句型不懂
I dropped out of Reed College after the first 6 months,but then stayed around as a drop-in for another 18 months or so before I really quit.So why did I drop out
stayed around怎么解释?for another 18 months or so 是stay的时间状语么?

stay around 徘徊,as 是由于,for another 18 months or so就是stay around的状语,徘徊了大概18个月
大意是
我到Reed College过完前6个月后就放弃了,但是由于踌躇,在我真正退出之前仍然徘徊了大约18个月.
