Why Don ' t Babies Talk Like Adults?

Over the past half-century,scientists have settled on two reasonable theories related to babytalk.One
states that a young child's brain needs time to master language,in the same way that it does to master other
abilities such as physical movement. The second theory states that a child's vocabulary level is the key fac-
tor. According to this theory,some key steps have to occur in a logical sequence before sentence formation
occurs.Children's mathematical knowledge develops in the same way.
In 2007,researchers at Harvard University,who were studying the two theories,found a clever way to
test them.More than 20,000 internationally adopted children enter the U.S.each year. Many of them no lon-
ger hear their birth language after they arrive,and they must learn English more or less the same way infants
do一that is,by listening and by trial and error. International adoptees don't take classes or use a dictionary
when they are learning their new tongue and most of them don't have a well-developed first language.All of
these factors make them an ideal population in which to test these competing hypotheses about how language
is learned.
Neuroscientists Jesse Snedeker,Joy Geren and Carissa Shafto studied the language development of 27
children adopted from China between the ages of two and five years.These children began learning English
at an older age than US natives and had more mature brains with which to tackle the task.Even so,just as
with American-born infants,their first English sentences consisted of single words and were largely bereft（缺
乏的）of function words , word endings and verbs. The adoptees then went through the same stages as typical
American-born children,though at a faster clip.The adoptees and native children started combining words in
sentences when their vocabulary reached the same sizes,further suggesting that what matters is not how old
you are or how mature your brain is,but the number of words you know.
This finding一that having more mature brains did not help the adoptees avoid the toddler-talk stage一
suggests that babies speak in babytalk not because they have baby brains,but because they have only just
started learning and need time to gain enough vocabulary to be able to expand their conversations.Before
long,the one-word stage will give way to the two-word stage and so on. Learning how to chat like an adult is
a gradual process.
But this potential answer also raises an even older and more difficult question.Adult immigrants who
learn a second language rarely achieve the same proficiency in a foreign language as the average child raised
as a native speaker. Researchers have long suspected there is a"critical period"for language development,
after which it cannot proceed with full success to fluency.Yet we still do not understand this critical period or
know why it ends. When the writer says"critical period",he means a period when________.
A.studies produce useful results
B.adults need to be taught like children
C.language learning takes place effectively
D.immigrants want to learn another language
