Question: what cultures do you legitly like?
You must be honest about this question, or you will never make it to the 7 language mark. This is why I was perfectly able to learn Japanese, why every attempt on learning Spanish has failed me very quickly.
Well if English is your main language, there are several languages that have had a profound influence on English. The English language borrows a lot of words from Latin, French, Italian, and Old German so those will all be familiar to you if you study them.
Enlivo,
You can use 也 or 而且 or 并且 and some other words as a conjunction between clauses. Thus,
He is my brother, and he is my best friend. = 他是我哥哥/弟弟,也是我最好的朋友。 or 他是我哥哥/弟弟,而且是我最好的朋友。 (For some reason, 并且 is not appropriate to be used here.)
It seems that you need a textbook on grammar or syntax to facilitate your learning.
Hi admin! I would just like to say that what you did is a really wonderful project. Something where everyone can share and contribute on for learning. I noticed that others have already filled up some slots. I have added a few but I will research on the other idioms first and then I will get back to the list soon.
