这个英语句子对吗?

不定式符号to后面必须接动词，所以应该是I want read a book in a library.

I want to read a book in a library.
I want to in a library read a book.
这两句话都是对的，
want to do sth固定搭配．
in a library 放前从语句上分析是没有错的。

I want to read a book in a library.

I want to go to a library and read a book.

I want to read a book in a library.
I want to in a library read a book.

i want go to the library reading some books
