We are learning English。But how we learn English wall。A student can know a lot about English。But maybe he can’t speak English。
If you want to know how to swim，You must get into the river。If you want to be a football player。You must play football。
So you see。You learn by using it。You must listen to your teacher in class。You must speak English to your classmates every day。and also you must write something in English。Then one day you may find your English is very well。
