Reading for Fun and the Brain
1Children who started reading for fun early did better on tests later, a large study found. Researchers at the University of Cambridge in the U.K. and Fudan University in China did the study.
2They used data on more than 10,000 children in the United States. The children were 9 to 11 years old when the data was first collected. Their parents answered questions about their reading.
3About half of the children read for fun for three years or more. These children got better grades at school. They also had fewer signs of depression and stress. They used screens less and slept longer.
4For test scores, the best amount was about 12 hours of reading a week. That is less than two hours a day. Reading more than that did not bring extra benefits. The researchers think too much reading may leave less time for sports and friends.
5The study shows a link, but it does not prove that reading causes these changes. The team also took family income into account.

全文訳
1小さいころから楽しみで本を読み始めた子どもは、のちのテストでよい結果を出した、という大きな研究が出ました。研究をしたのは、イギリスのケンブリッジ大学と中国の復旦(ふくたん)大学の研究者たちです。
2研究者たちは、アメリカの1万人以上の子どものデータを使いました。最初にデータを集めたとき、子どもたちは9歳から11歳でした。子どもの読書については、親が質問に答えました。
3子どもの約半分は、3年以上、楽しみで本を読んでいました。この子どもたちは、学校の成績がよりよいものでした。うつやストレスのサインも少なめでした。画面を見る時間が短く、睡眠時間は長めでした。
4テストの点数でいうと、いちばん良かったのは週に約12時間の読書でした。1日に2時間より少ない計算です。それ以上読んでも、さらによい結果にはつながりませんでした。研究者たちは、読書の時間が長すぎると、スポーツや友だちと過ごす時間が減るのかもしれない、と考えています。
5この研究は結びつきを示していますが、読書がこうした変化の原因だと証明したわけではありません。研究チームは、家庭の収入のちがいも計算に入れて調べました。
文法ポイント:比較級(better / fewer / less / longer)
2つをくらべて「より~」と言う形。本文では better grades(よりよい成績)、fewer signs(より少ないサイン)、used screens less(画面をより少なく使った)、slept longer(より長く眠った)。fewer は数えられる名詞、less は数えられないものや動作に使う。
