Don't traslate
When you want to create an English sentence, do not translate the words from your Mother tongue. The order of words is probably completely different and you will be both slow and incorrect by doing this. Instead, learn phrases and sentences so you don't have to think about the words you are saying. It should be automatic.
Learn and study phrases
Many students learn vocabulary and try to put many words together to create a proper sentence. It amazes me how many words some of my students know, but they cannot create a proper sentence. The reason is because they didn't study phrases. When children learn a language, they learn both words and phrases together. Likewise, you need to study and learn phrases.
