Translation:The sheep goes over the zebra crossing.
What the heck? Is zebra crossing an actual word used somewhere in the USA that I am not aware off? Never heard of this. I thought it was like a 'deer crossing'! A place that deer frequently travel across a road.
Ah, just found out. Zebra crossing is a British thing. Crosswalk is what it is called in the USA.
I agree with other comments. Zebra crossing is not a word we use in the USA. I suppose Duo wants us to learn British English to be well rounded. Some other sentence using sheep would be so easy to use and universally understood by English speakers.
