Do Czechs sell their blood instead of donating it? :o

[JanLyko]

No. There are 300,000 donors (out of 10 million population) donating for free and one Swiss company paying for plasma for needs of the pharmaceutical industry.

[BarbaraWhi574572]

why not "She sold her blood each week" of "Each week she sold her blood"

[VladaFu]

Options containing "each week" added.

To me 'each week' has a much more perfective feel. I much prefer 'Every week' , which just goes on forever.

Is prodávat imperfect? And prodat is perfect? How would she was selling her blood every week be written? I am starting to have a glimer of understanding with perfect & imperfect verbs. (I hope)

[VladaFu]

Correct. It would be the same as this one. "She was selling her blood every week." is accepted as a correct answer here.

[DeniseSchl5]

Good, that's a relief. I remembered it as imperfect and I used it that way so there most have been some other mistake in my sentence. Thanks!

I really don't get this section. What's the difference between 'prodala' and 'prodávala'?

[VladaFu]

You really should read the Tips and notes about verb aspect. You can add any additional material of your choice, you can find loads by a simple web search

prodala - sold, the selling process was finished
prodávala - she was selling, either she was selling it for some time or she used to sell it repeatedly
