Hi there
Why do people in many countries speak English so badly? That includes Japan....
This is the result of decades of hiring "native speakers" as teachers. It is so naive to believe a native speaker is also a good language teacher. In reality, most of them have no idea about linguistics or about phonetics and the very grammar of their language is a big mystery to them.
They are also excessively "tolerant", probably because they sense their own incompetence.
So why not use real EFL teachers to REPAIR what the amateurs did wrongly?
Let's begin to REPAIR people's bad English with special online classes.
