Teens who 'never' or 'hardly ever' read for fun has gone from 8 percent to 22 percent in 10 years, according to a Common Sense Media report. What can parents do to help reverse the drop? 这段是文章的引言内容，所以可以判断出以下直接引语中 who 前省略了 of teens。

According to the report’s key findings, “the proportion of teens who say they ‘never’ or ‘hardly ever’ read for fun has gone from 8 percent of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and 27 percent respectively today.”

而通过网友这段内容的下一段，也可得知这样判断有理有据：The most dramatic drop is shown in teen reading habits, with the rate of teens saying they read "often" dropping from 64 percent in 1984 to just 19 percent in 2012. Among those ages 6-17, the proportion of "daily" readers is still estimated around 34 percent.
