Wednesday!!!

Today I knew found out two teachers are in charge of teaching my class. We will have one teacher is form on from Monday to Wednesday, and another teacher is on on the other days. I look forward to meeting another the other teacher, who we are told is from the the teacher said is form Australia. So I'm excited about it because I can learn Aussie slang!
In the morning class, I studied the tenses the time expression with past simple and present perfect. I'd learnt about it them before but they are a little confusing. I was thinking I should sometimes needed to revise it sometime. It was a good opportunity.
In the afternoon, as reading practice, I read a story. The content was It was about ''Nice Fake'', which means like when shop assistants usually pretend to be a friend to draw attract a customer's attention, but that makes the customer feel unpleasant or not according to the ways. That was an interesting article, although there were heaps of words I didn't know.
After I said goodbye to the teacher and my friends, I just went back home. Since I moved to Sydney, I've got been sleepy and tired. I guess that reflects shows that I'm not used to a big busy city like Sydney yet.
When I was lying on my bed and listening to music my ear phones was suddenly broken. I must buy new ones tomorrow after school.
