Doesn't wrong in definition, only there's a better word. Like "cage fight" or "cage battle". All the above example just make more sense.

My wishes

 

I am a chinese girl. 

My mother and my father, my parents, they all in business.

My wishes are that my parents are all healthy and I can speak English fluently.

(Because)I try very hard.

 

You gotta admit that every language's vocabulary need to be excite. But you have to choose the best for you to memorize those word into your daily life. For me, I try to memorize 10 words per day 60 words per week. Monday 10 words. Tuesday new 10 words and Monday's 10 words. I use google translate a lot and I always listen to that word at least 10 times. Pronounce it out loud and write it down on the paper at least 10 times. The most important thing for me was the example of that sentence, you also need to remember that too.

he tell me 他告诉我 I tell him 我告诉他 etc 等等 This sentence doesn't quite complete. If you can provide more would be helpful to translate it.

I would say 死鬼 is not devil. It means jerk in this sentence. Yeah, doesn't sound so nice. 这个死鬼他什么时候才回来呢 => When will this jerk coming back?

I like him a lot, but I'm not going to force him to like me back. Let it be... => 順其自然 It's too hard for me. I don't want anything anymore. Let it be... => 無所謂 (I don't care)
