选择恰当的主题句。

D. My first wife and I only had one child.
E. I've always wanted the best for her.
                                                                   Family Matters
     Oliver Darrow, actor, talks about his daughter, Carmen. 
       1    It might have been nice to have more. I would have liked a son,but we just had Carmen.
      I see her as my best friend. I think she always comes to me first if she has a problem. We have the same
sense of humour and share many interests,except that she's crazy about animals,obsessed with them-she has
always had dogs,cats,and horses in her life. 
        2    That's when they need their parents most. But as soon as Carmen went to school,she seemed to
grow up and grow apart from her family, and any father finds it difficult with a teenage daughter. She was
very moody and had an odd group of friends. There was an endless stream of strange young men coming to
our house. I remember I once got annoyed with her in front of her friends and she didn't talk to me for days.
         3    We sent her to a good school, but she wasn't happy there. She left because she wanted to become
an actress.so with my connections I got her into drama school. but she didn't like that either. She worked for
a while,doing small roles in films, but she must have found it boring because she gave it up,though she never
really said why. She got married a few years ago; her husband's a vet. They must be happy because they work
together. and she lores animals. 
       4    When she was younger I used to take her to the opera-that's nay passion-but she can't have liked it
very much because she hasn't come with me for years. I don't think she goes to the cinema or watches TV
much. She might watch my films. but I don't know. It's not the kind of thing she talks to me about.
     I'm very pleased to have Carmen. She's a good daughter, but I don't think she likes my new wife very
much because she doesn't visit us very often. I'm looking forward to being a grandfather one day. I hope she'll
have a son.
