The vocabulary of babies who are bilingual remains flexible as they grow up and boosts their speaking ability as toddlers, a university study has found. 一项大学研究发现，接受双语教育的宝宝在成长过程中可以灵活地掌握两门语言的词汇，而且学步时期的口语表达能力也能有所提高。 Babies and children have a great ability to learn a second language but that begins to fade as early as their first birthdays. 婴儿和儿童在学习第二门语言方面能力很强，但早在他们过第一个生日的时候，这种能力就开始逐渐退化。 Now researchers at the University of Washington's Institute for Learning &Brain Sciences are investigating the brain mechanisms that contribute to infants' prowessat learning languages, with the hope that the findings could boost bilingualism in adults, too. 目前，华盛顿大学学习与脑科学研究所的研究人员们在对促进婴儿非凡的语言能力的大脑机制进行研究，他们希望研究结果也可以推动成人的双语教育。 In the research, the scientists report that the brains of babies raised in bilingual households show a longer period of being flexible to different languages, especially if they hear a lot of language at home. 在研究中，科学家们报告说，成长在双语家庭中、特别是在家能听到大量语言交流的宝宝的大脑表现出更长时间的对不同语言的灵敏度。 |
