同学好

应该使用 an old woman 而不是 a old woman，因为以元音音素开头的单词前应使用 an。

concentrately 不是一个正确的词，应该是 concentratedly 或更自然的表达是 intently。

Can you guess who she is? Yes, she is my grandma.
在 Yes 后面应该加一个逗号。

About two years ago, when my grandma just came here, she always said, “No one knows me, I'd rather live in the countryside.
在时间状语 About two years ago 之后应该有逗号。

when my grandma just came here 中的 just 可以改为 first 以增加清晰度： when my grandma first came here。

My father didn’t want my grandma to be lonely. He bought a radio from the supermarket. Since my grandma has had this radio, her life has become interesting.
Since my grandma has this radio 应该使用完成时态 has had。同样，her life become interesting 应该是 her life has become interesting。

She often listens to the radio in her spare time. After we got home, she sometimes talks about the news with us. She felt very happy.
listens to radio 应该是 listens to the radio。
时态需要一致，所以 After we got home 应该是 After we get home。同理，She felt very happy 应该是 She feels very happy。

Nowadays, my grandma watches TV, listens to the radio, and reads the newspaper regularly in her free time.
Nowaday 应该是 Nowadays。watchs Tv 应该是 watches TV。in her available 应该改为 in her free time。

I hope my grandma lives happily with us.
lives happiness 应该是 lives happily。
