#2 sounds more natural to me.

I prefer coffee to tea.
I prefer to live in my own house rather than a rented flat.
I prefer to read paper books rather than e-books.
I prefer swimming in a sea to lying on a beach.

I'd prefer to take one more dress.
I'd rather not go out today.

I'd rather you washed the dishes.

**note: (I, you, he, she, they) = prefer
(My, your, his, her, their) = preference 
Example: What is your preference for dinner?

While technically, both are correct. The first sentence is a more formal "Old Fashioned" way of speaking. The second sentence is more normal today. So, I would recommend using it.

It is "more than one Orange" Orange is singular in this case. If the sentence reads "more than two" (or more) then, it becomes Oranges.

Instead of "nothing as such called" "nothing called" sounds more natural. However, there are multiple ways to say this, so it can be difficult to know how to phrase it correctly, depending on the sentence, or situation. "In my company, there is nothing called Duty Leave." "In my company, we don't have Duty Leave." "In my company, Duty Leave doesn't exist."

Hi, everyone! I want to talk about my cat. I used to have two cats. But, the white one died, because of cancer. Now, I have just the black cat. That one is little bit strange. She doesn't play and run. She just always asks for food. She used to be slim. But now, she is fat. My sister loves her anyway.
