The first ever entry on italki

Hello everyone! A friend of mine has recommended italki to me, in a case I have a questions related to the English language and have no one to answer them.This way I got here. I am learning English at school and I think that we don't have enough classes to learn the language so that everyone can speak it at the essential level. The only thing I have learnt from my school is the basic vocabulary. I know how to name things like:"a grey cat that has whiskers caught a mouse in his paws." I have to say that my school is not bad at teaching English. I think every student in our class who really followed the curriculum knows how to say that sentence. However, I want to learn more in order to be able to understand films and songs and talk to the native speakers. My friend recommended me to start with reading books, and I think this helped me enrich my vocabulary, but I find reading boring. I don't have enough patience to look up every word in the dictionary, especially if there is a bunch of them. I would rather watch a video or listen to a podcast. Aye, today I was learning some phrasal verbs. Could you check the sentences that I made:
1. The police put down the strike that started yesterday at the military factory.
2. After a long trip to a neighbouring town I dropped off in my armchair.
3. Eugene broke off a piece of chocolate and gave it to me to celebrate his break-off (break up is better here) with Maria.
4. The class fell through due to the holiday.
5. Parents who do not want their children to be vaccinated have to sign off a paper to state that they are refusing.
