Lily, I can't catch up with the English teacher very well.
What's the problem?
You are quite good at English. Can you help me with it?
Sure, but you'd better take an additional course in some English schools.
English schools? What's that?
This kind of school is good at helping people to improve their English.
Is that different from our school's English course?
Yes. Before you start your training, they will test you on your English first.
Then?
Then they will recommend you the class that suits you.
Really? How good can my English get there?
You see how well I am doing. I studied there, too.
