English Diary

Today I woke up at 8:00 am.
I had to return a car which I rented 2 days ago for my trip to Gold Coast.
Therefore I and my two friends and I went to the car center and returned the car.
Then we came back to the Brisbane city by train. We had to wait for the train for 30 minutes. It was boring.
We, I and my two friends went to the states library, and we slept there for 1 hour.
Afterwards, we came back home and go went to the gym, which is inside the apartment building.
I ran on the running machine (running machine treadmill) for 20 minutes.
I just took a shower just now and now I am writing this.

I decided to write a diary here in English everyday, because it is helpful to improve my english.
I hope someone will correct my poor writing.
Thank you :)

Hi 성준! This was a good diary entry, and there were only small mistakes. I could always understand what you were saying ^^

I wanted to quickly point out that the sentence "Therefore my two friends and I went to the car center  and returned the car." makes sense, but naturally in English I would put it together with the sentence before it like this:

"I had to return a car which I rented 2 days ago for my trip to Gold Coast, so my two friends and I went to the car center and returned the car."

Also, I wasn't sure if I needed to make a correction when you said "Brisbane city". For most cities, you don't need to add the word "city" after. You can simply say "Toronto" and not "Toronto city". For some cities you do need to write "city" after the city name because that is also the name of a state or province, such as "Quebec City" or "New York City". If Brisbane is a city like this, you should make the "c" in "city" into a capital "C". If you do not need to write "city" after "Brisbane" then you can just remove it.

My only other confusion was when you wrote "states library". If this is the library of the state, it would be written "state's library". If it is the name of the library, it would be capitalized "States Library". If there is some other reason it is called this that I don't know about, you may have written it correctly, but I just wanted to let you know it was a little bit confusing for me there.

I hope this all made sense! If you have any questions or want me to clarify anything, just let me know by commenting below. Good luck!
