4．We know that reading is good for children and for adults as well.Now a new study suggests that just being around books has its benefits - even if you don't read them a lot.A team of researchers in Australia finds that growing up in a home with a sizable library improves literacy，number sense and even technological knowledge in later life.
The researchers were interested in what is called the "Radiation Effect" "Radiation Effect" is a situation where children grow up around books，even though they don't read them as much as their parents would like them to.But somehow books benefit them.
Joanna Sikora，a sociologist at the Australian National University，and her colleagues studied data collected between 2011 and 2015.The survey tested more than 160，000 adults from 31 different societies，and it included a question about how many books testers had in their homes during adolescence（青春期的）.
"We found that people who grew 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 fact，teens who only made it through high school but were raised in a bookish environment were successful as well in adulthood as college graduates who grew up in a house lacking books.
"So if we grow up in a house，in a home where parents enjoy books，where books are given as birthday presents and cherished and valued，this is something that becomes a part of our identity and gives us this lifelong influence to improve our reading and writing ability." said Sikora.
So keep those shelves filled with books.Your kids will not only be grateful，they'll be more likely to be able to spell grateful correctly as well.
