Translation of extractor in German

I think we will start Spanish-English and then German-Spanish. Were my explanations clear that when the correct word appeared in the alternative suggestions one needs just to press skip? I think it is normal.
Anyway, there are a lot of people on board and I no matter how high the waves may be, I always suffer from nausea or seasickness. I have not been on a small boat before. I will have to vomit.
I have problems with adjectives, endings and articles. The grammar is so difficult. I am very happy to learn Spanish with you. What went wrong with the lessons? Thanks and best regards.
