can you make one for my brother.he can fly a kite and he likes to fly them very much

根据句意,them 指的是‘ kites ' 风筝　　如果指kites的话，那在句子中的意思是指风筝类的意思对吗。。。。？？？？　　对He can fly a kite.和Mike teaches me throw it like that and I teach him to fly the kite like this. fly a kite 在字典中能查到 放风筝的意思 但第二句中的 fly the kite 好像也是放风筝的意思。但为什么不用a 而用the?????请高人指教后面的the kite 是特指前面提到的kite
