上个星期我读了一本关于流行音乐的书。用英语怎么说

I read a book about pop music last week.( about 也可以换成on)

last week, i read a book about pop music.

此处的read 是过去时，注意读音有变化。
此处pop music应该是不加冠词的，
例句：
I like listening to pop music.
I am most familiar with classical and pop music.

I read a book about pop-music last week

Last week I read a book about the pop music.
