His father works in a factory, he is a worker
Làm gì có gì sai đâu em ?
His father is a worker, he works in a factory.
vì có 2 chữ a nhưng nếu đặt câu là he is a father ko đc
His father works in a factory, he is a worker
his father is a worker works in a factory
chắc là thế thử lên google xem câu lúc nãy là đoán bừa
