To begin with, some high-level standing vocable I learned over the last two months in this school. As you know the English language has more than 500, so it is good for me if I know half of them. When I say high-level vocablary I mean in B2 and C1 levels. For example "Surroundings" this word means things near me, " I'm in my room and the surroundings me my books,laptop and for sure my phone. Other idioms like "Log, food and Branch", so when you need to set fire you need to use a lot of logs that already come from the trees , especially from one or more branches. Flooding, that water covered the streets after rain. It's really high-level vocable for me also I think that amazing words you can use to talk about some situations in real life,I mean close to my simple life. Such as when I'm in the desert with my friends in the Winter we must sit on fire to make us feel warm, so the logs are useful for us. Actually, there are people who use it also for decoration inside their houses.
