The benefits of a bilingual brain
Hablas espafiol?Parlez-yous francais? 你会说中文吗?If you answered, “sí,” “oui,” or “会” and you’re watching this in English, _________ are you belong to the world’s bilingual and multilingual majority. And besides having an easier time traveling or watching movies without subtitles, knowing two or more languages means that your brain may actually look and work _________ than those of your monolingual friends.
So what does it really mean to know a language? Language ability is typically measured in two active parts, speaking and writing, and two _________ parts, listening and reading. While a(n) _________ bilingual has near equal abilities across the board in two languages, most bilingual around the world know and use their languages in varying proportions. And _________ their situation and how they acquired each language, they can be _________ into three general types. For example, let’s take Gabriella, whose family immigrates to the US from Peru when she’s two-years old. As a compound bilingual, Gabriella develops two linguistic codes simultaneously (同时地), with a single set of concepts, learning both English and Spanish as she begins to _________ the world around her. Her teenage brother, on the other hand, might be a coordinate bilingual, working with two sets of concepts, learning English in school, while _________ to speak Spanish at home and with friends. Finally, Gabriella’s parents are likely to be subordinate (次要的) bilinguals who learn a secondary language by filtering it through their mother_________.
Because all types of bilingual people can become fully proficient in a language __________ accent or pronunciation, the difference may not be apparent to a casual observer. But recent __________·in brain imaging technology have given neurolinguists a glimpse into how specific aspects of language learning affect the bilingual brain. It’s well known that the brain’s left hemisphere is more dominant and analytical in __________ processes. while the right hemisphere is more active in emotional and social ones, though this is a matter of degree, not an absolute split. The fact that language involves both types of functions while lateralization (脑部的偏侧性) develops gradually with age,has led to the critical period hypothesis. According to this theory, children learn languages more easily, because the plasticity of their developing brains lets them use both hemispheres in language acquisition, while in most adults, language is lateralized to one hemisphere, usually the left.
But regardless of when you acquire additional languages, being multilingual gives your brain some__________ advantages. Some of these are even visible, such as higher density of the grey matter that contains most of your brain’s neurons and synapses, and more activity in certain regions when engaging a second language. The heightened __________ a bilingual brain receives throughout its life can also help delay the onset of diseases, like Alzheimer’s and dementia by as much as five years.
So, while bilingualism may not __________ make you smarter, it does make your brain more healthy, complex and actively engaged, and even if you didn’t have the good fortune of learning a second language as a child, it’s never too late to do yourself a favor and make the linguistic leap from, “Hello,” to, “Hola,” “Bonjour” or “你好’s” because when it comes to our brains a little exercise can go a long way.
