English Conversation Lesson

I took an English conversation class on italki for the first time. That was awesome! I did had it with a native English speaker. He was really patient and kind. I learned the difference between "could" and "be able to do". When I had learned (using the past perfect because you talk about something that happened before another past action: learning the difference) these phrase in school for the first time, my teacher had said these/they (any of them is OK) are had the same meaning. These are transferred into one Japanese word so I didn't distinguish these two phrases. However, I learned that "could" is used when we express the a (this is just a detail, but since you don't refer to a specific ability...) general ability. On the other hand, we use "be able to do" when we express the one single accomplishment. It was a big deal for me because I learned to use these phrases correctly. I'm going to take his lesson again!

All in all, the text looks quite good. Keep at it!
