Answer

I think one problem you are having is that you are dividing syllables into stressed and unstressed. This will make it difficult for you to really hear what is happening. English has three levels of stress: primary, secondary and unstressed.
So in your first sentence, the stress pattern is probably something like:

It's (unstressed) someone (secondary stress) who (unstressed) works (secondary stress) in (unstressed) a (unstressed) hospital (primary stress).

Then within long words there is primary, secondary and unstressed too.
