I'm not a parent either but I agree with what our forumers say...

Personally I did not like getting yelled at everytime I did not do my homework. I can tell you that I had no childhood at all as my mom would make me sit in front of her and watch me do my homework like a hawk.

That worked.. in a sense I would voluntarily do my hw right until high school. But of course, I hated it. I grew up with people making fun of me cos I had "no life".

So I would say go for a more gentle approach? The example of telling your daughter that she would have to do jobs like clean toilet or become road sweeper if she doesn't study is good. My mom did that too and I still keep that in mind til today.

As for language, try to get more interesting reading materials (let her choose on her own) or encourage her to mix with friends who speak different languages. I don't know if this would be a good idea but I picked up languages from watching TV.
