The earth goes round the sun. Hello. I found this sentence in my textbook. What is the different between "The earth goes 'round' the sun." and "The earth goes 'around' the sun."? Thank you!

留学のことが決めました とても緊張です。 友たちと話すはいつも楽しくてしてますが、本当に日本に行ったら、先生たちとバイト先の方達には丁寧語を使わないと。 そのために、本を読んで勉強しています。 ても敬語は本当に深いです。 どうな状況でどうんな言葉を使うとか色々なことを注意が必要です。 今はまだ早すぎるかも知りませんが、私も礼儀正しい人になりたいです。 外国人こそ、もっと日本文化を知りたいです。 それはやはり言語は第一歩かな。 頑張ります！

4/17 My application has been accepted!! My application to be an Community Tutor on italki has been accepted !! I'm so happy with the news! As a language learner, I really willing to help those who do want to learn my language as well. I become a language learner has been around one and half year, first was Japanese. And did many research on the internet, which helps me a lot and let me passed the JLPY N2 after just one year. My self-confidence grow not just because I passed the exam, but the whole process i've passed is so alive. I was so opened and so happily living with a new culture or a new language. And I don't afraid of making mistake anymore because I knew that whenever I made mistake is a chance to help me getting better. When I was a child, I was forced to learn English, I really hate those vocabulary, Grammar, the sound or even the stories which was talked by English. But, maybe it's time for me to face this language again. Would you help?
