How do i say "i don't have any siblings" in french?

Need this translated in french asap ! last week was lots of fun. on monday i attended class and did my homework then left for the beach with friends. on tuesday i went to chapman university to take a tour of the campus, then i had coffee with friends. on wednesday i did my class work then went out to see a movie. on thursday i went to the beach like i had on monday. after my friends got out of school on friday we drove around the city and went to the mountains to watch the sunrise.

Using the prepositions as a hint, choose the correct conjugation of the appropriate verb. je __ a la bibliotheque avec ma soeur. -vais-va-vas-viens

In this french correct ? i dont know if the person i am talking to is a female or male im assuming that wouldn't affect it but i kind of forget . i know all adjectives agree with the nouns that they modify. métier is masculine so i use the adjective bon and bon is masculine so i use un? is that how it works je pense un bon métier pour toi est un artiste ou un architecte. i think a good job for you is an artist or an architect
