Playing with tenses - Past perfect vs Past perfect continuous.
I've been learning english for a long time, but I never studied grammar.So by now I'm taking lessons. But I'm a little blocked today.
I made this example:
Past perfec - “Manuel had repaired many cars before he received his mechanic's license”
Past perfect continuous - “Manuel had been repairing many cars for years until he received his mechanic’s license”
Now I need to do the same with this
Past perfect - “She had never seen such beautiful painting before she visited Sistine Chapel”
Past perfect continuous - (((????))))
I tried one, but my teacher told me was wrong, the grammar.
“She had been seeing many painting, but nothing as beautiful as Sistine Chapel”
