1 . We know that reading is good for children. Now, a new study suggests that just being around books has its benefits. A team of researchers in Australia finds that growing up with a large library at home improves literacy (读写能力)，number-sense, and even technological skills in later life. It appeared in the journal Social Science Research.
The researchers were exploring the advantages of scholarly culture. They were interested in a curious observation that some call the “radiation effect”. “Radiation effect is a situation where children grow up around books, but they don't read books. But somehow books benefit them, even though they don't read them as much as their parents wish them to.” Joanna Sikora, a sociologist in Australia. Joana and her colleagues analysed data collected between 2011 and 2015 by the Organization for Economic Development. The survey assessed the literacy, numeracy(计算能力), and technological competency of more than 160 ,000 adults from 31 countries. And it included a question about how many books participants had in their homes during adolescence. “What we were able to make clear was that people growing up around books had better literacy, numeracy and digital problem-solving skills than people who had fewer books growing up but had similar education levels, similar jobs, and even similar adult habits in terms of reading or working at various numeracy-improving activities.”
In fact, teens who only made it through high school but were raised in a bookish environment did as well in adulthood as college graduates who grew up in a house without books. Now, how might mere exposure lead to intellectual improvement? “If we grow up in a house, in a home where parents enjoy books，where books are given as birthday presents and valued, this is something that becomes a part of our identity and gives us this lifelong urge to always come close to books and read more than we would.”
So keep shelves piled with books. Your kids will not only be grateful, they’ll be more likely to be able to spell grateful correctly as well.
