I have come across a few sentences that I had to look back over my shoulder while typing out, afraid to see if anyone behind me saw what I typed.

: )

My preliminary impression is that the English sentences have been written by German speakers; I am guessing teachers of German courses for Americans. Their English is generally good, but it should still be reviewed by an educated native English speaker.

Yeah, I was hoping the developers would see this and fix it but I'm still getting "I have a woman." and "I have a man." as sentences to translate. Maybe I'll get it wrong on purpose so I can send feedback to them or post an insight about this again with a "Yo! Developers!" in the title.

My favorite was "the bear is eating a cheese sandwich"

Funny, but certainly acceptable in the home country of Lewis Carroll
