Non-defining clause, Sub-ordinator, Introductory phrase...

[abc71044]

Did I write these sentense correctly?

1.) Non-defining clause
Miriam Yeung, who is a famous singer in HK, is my idol.

2.) Definite article
I think she is the most beautiful woman.

3.) Sub-ordinator
We brought a lot of snack because we afraid we will feel hungry at the night.

4.) Introductory phrase
After we have lunch, we go to watch a movie.

Many thanks

1.) Non-defining clause
Miriam Yeung, who is a famous singer in HK, is my idol. -- OK

2.) Definite article
I think she is the most beautiful woman. -- OK; I would add a defining phrase: 'the most beautiful woman in the world'.

3.) Subordinator (one word)
We brought a lot of snack because we afraid we will feel hungry at the night. -- Subordinator is OK, but there are other errors: 'Snack' is countable, so 'snacks'; 'we were afraid we would feel hungry at night'.

4.) Introductory phrase -- You have produced an introductory clause; was that your plan?
After we have lunch, we go to watch a movie. -- OK; 'to watch' is not necessary and would be more natural if omitted.
