[正] For the latest couple of years the tertiary industry in our country has been developing very rapidly.

注：“第一产业”是 the primary industry，“第二产业”是 the secondary industry,但“第三产业”不是 the third industry，而是 the tertiary industry。其实，tertiary 与 third 是同义的，都是“第三”的意思，这样用只是约定俗成。另外，“第三产业”还可以说成 the service industry，因为第三产业主要指服务业。
