I need to know the difference in form and meaning between the members of each of the following sentence pairs:
1. Is there anything that worries you?
2. It is something that worries you, isn't it?
First of all: How should I analyse them?
I am working my wits out on this...
I am still working on this, and my main problem seems to be the use of it and there in the two sentences. They are both aticipatory subjects, as far as I can understand. I believe that the difference in meaning has to do do with the use of there and it, but I am not able to figure it out.
I would be really greatful if anyone could help me out on this. Please?
