As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment. It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.

What does the underlined phrase “an added meaning” in paragraph 3 refer to?

A．Pleasure from working in the library.

B．Joy of reading passed on in the family.

C．Wonderment from acting out the stories.

D．A closer bond developed with the readers.
