I can do a lot of things. I can speak English very well. And English was very easy to me. But I was not satisfied. I want to learn more about English. Especially junior high school's English. My sister helps me but when she was away I don't know how to do about this kind of things.
I can swim but not very well. I want to sign up for a freestyle swimming class. That will help me to learn how to swim. And I will practice every day.
Before I can cook but only pasta. My teacher was my mom, I am learning to her. Now I can boiled eggs,cook rice in a rice cooker and I can even cook dumplings. But I still wasn't satisfied.
Our people can learn things, but some animals can't, just like birds. It is impossible for us to make birds swim as they are not suited for swimming in the first place. And they are simply not built for it. And our body can do everything we want.
