afewthousandyears还是afewthousandsof

是a few thousands of ，例如：

1、It` s funny people making a few thousands of yuan a month worry about the livelihood of those making hundred times more.月薪只有几千元的人去担忧那些收入超过他们几百倍的人的生活，这很滑稽。

2、Testimonials from a few of our thousands of satisfied clients.推荐几个从客户满意我们的数千人。
