One of the handicaps to becoming a proficient user of English is over-reliance on your mother tongue.  At this level, you should really avoid using translation dictionaries for everything except names of animals or plants, for example.  It’s more difficult to explain what a birch tree is than to simply translate it, but it’s vastly more helpful to your overall understanding of English to look up most words in an English dictionary to see the different ways they are used.  Phrasal verbs and collocations are usually explained better by monolingual dictionaries as well.
