My first article in English

l know that there are many people learning English now, especially Chinese people. We have a population of with 1.3 billion people, almost a half of Chinese people are learning the most popular language in the world; so as a Chinese girl, l dont think it will make sense if l am only learning English. That is why l want to learn Norwegian here!
Maybe my English sucks, but l still try my best to learn it well and wonder if it could be my second native language one day. There It is no doubt that l know English much better if compared to than my Norwegian, and l have been looking for some connections between English and Norwegian because some English words and its grammar were developed adopted from Norwegian, so l hope l can learn English very well and master my favorite languages!

"I know that there are emany people learning English now" could also be "I know that that there are many people who/that learn English now".

Every sentence should have one main clause/statement, and everything else attached to it by commas should add meaning to that statement (ie. adding time, place, contrast). If you want to make a new 'main statement', make a new sentence.

This was very good. Keep up the good work!
