辅导班汉翻英的例句：
他戴了一副非常滑稽的眼镜。
He is wearing a pair of glasses which are funny.
正在画画的男生是我的一个好朋友
The boy who is drawing pictures is my good friend.
昨天我在公园遇见了教我钢琴的老师。
Yesterday I met my teacher who teaches me playing the piano in the park.
我的疑问：
句中，戴眼镜可否写成 wearing glasses？另外，我觉得a pair of glasses which are funny 应改为 a pair of glasses which is funny，由于 which 指代的是 pair 而不是 glasses。
句中，画画应否改为drawing a picture 或 drawing the picture。另外 my good friend 是不是应改为 a good friend of mine？
句中，我觉得翻译的不对。译文的意思变成了：昨天我遇见了在公园教我钢琴的老师。
我感觉应改为：
Yesterday I met my teacher in the park，who teaches me playing the piano.
还有：my teacher 是不是应改为 the teacher？
请专家指教，谢谢！
Yesterday I met my teacher in the park，who teaches me playing the piano.应该改为：
Yesterday I met my teacher in the park，who teaches me to play the piano.
