As you have learned a while back, the accusative prepositions always demand the accusative case. This song will help you to ingrain them deep into your memory. Click play and enjoy the beautfy of German grammar (when learned with SmarterGerman).

Here they are for reference:

entlang - along
durch - through
um - around (time/place) / at (time)
gegen - around (time) / against
für - for (careful: the EN use "for" like sugar, way too often. Germans are scroogy with it)
bis - until (time/place)
ohne - without

With a little help from my friend: If you like this song, you could help me and go to YT by clicking this link, like the video and if possible subscribe to my channel. That helps a lot with keeping the boat afloat as Youtube is a really strong marketing tool (but a lousy learning tool).
