For example, here is something I learned in reading an essay by an upper-year student today (not an ESL student, btw):
"Time sure gave way to new traditions and labels as currently we live in a world of politically correct sentences and empirically based findings."
I also learned, from this same enlightening piece of work, that the 20th century was the Victorian era. And that same-sex marriage is legal in over half the states in the U.S.
As well, the writer asserted that, "[people] of the past should be proud that the trails [sic] and tribulations they faces [sic] helped pave the path..." To which I could not help but respond, in the margin, "They can't be proud; they're dead."
An upper-year student.
This is why I drink wine, in case you were wondering.
