I won't give any specific advice, since this looks a lot like a homework assignment, and I know I wouldn't want my students getting this sort of help off of the internet, but some general tips.
1. Watch adjective/noun and subject/verb agreement. S/V is generally okay, but you make a few mistakes.
2. Some of your sentences are missing Indirect Objects.
3. Masculine and neuter nouns in the genitive need an -s or -es added on to the end.
4. The following words are wrong: toeten (as in "Als sie jung war, toetete sie..."), Schlussfolgerung, and Rolle Modelle.
Leo.de is your friend.
5. And it's "Hilf mir", not helfe mir. You make a few similar mistakes with strong verbs throughout.
Hope this helps.
