很多人想当然地以为，有哥哥姐姐陪伴的孩子学语言会更快，因为有更多人可以和自己交流。但是科学家的一项研究却得出了相反的结论。 Having an older brother comes with plenty of benefits. Big brothers tend to look out for their younger counterparts, and despite the occasional rocky moment here and there, many siblings enjoy life-long close relationships. However, a new study finds an interesting downside: children with older brothers take longer when it comes to developing language skills. 有一个哥哥好处多多。哥哥通常都会保护弟妹，尽管偶尔也会吵架，但许多兄弟或兄妹一辈子关系都很亲密。然而，一项研究发现了一个有趣的弊端：有哥哥的孩子学语言更慢。 |
