[00:00.00]Part B You will hear a lecture about child development.
[00:07.13]Answer questions 6--10 while you listen.
[00:12.33]Use not more than 8 words for each answer.
[00:18.13]You will hear the recording twice.
[00:22.02]You now have 25 seconds to read the questions.
[00:27.51]1.Who is the speaker talking to?( )
[00:29.52]2.What is the main topic of this talk?( )
[00:31.50]3.When do children first begin to make language-like noises?()
[00:33.52]4.At what age do most children begin to master the basics of grammar?( )
[00:35.50]5.What does the speaker say about the grammatical mistakes
[00:37.51]that four-year-olds make?( )
[00:40.80]Now,in the last few minutes of class.
[00:45.11]I'd like to address a slightly different issue:
[00:49.71]the question of how children learn to talk.
[00:54.31]Learning to speak their own language
[00:58.31]is one of children's greatest accomplishments,
[01:02.72]yet it is a somewhat mysterious process.
[01:07.60]Children first begin to make language-like noises
[01:12.52]when they are between two and four months old.
[01:17.30]These noises generally begin with the letters 'g'and 'k'
[01:22.99]and because these sounds -- "goo" and "koo"
[01:28.29]--are the easiest sounds for infant mouths to make.
[01:33.57]Between four months and eight months,
[01:37.75]infants begin to babble meaningless syllables.
[01:42.77]Most common are those beginning with p,b,d,m,.or n sounds,
[01:51.26]followed by a vowel sound.
[01:55.04]Parents sometimes misinterpret these as actual words,such as mama or dada.
[02:03.04]Between six months and a year,babies say their first true words.
[02:09.54]Vocabulary grows slowly at first, usually only a few words a month,
[02:16.33]but once child has learned about Fifty words
[02:21.14]-- generally around 18 months--the pace picks up rapidly.
[02:27.23]At first,children say single words;
[02:32.03]then they begin forming two-word combinations:
[02:37.34]"all gone.""more milk," "see doggie."
[02:42.74]Children's two word combinations are so similar the world over
[02:49.04]that they read like translations of one another.
[02:53.92]Between the age of two and three,
[02:58.23]children can form complete sentences and have mastered the basis of grammar.
[03:05.13]Can you believe it?
[03:07.92]A two-and-a-half-year-old toddler is a grammatical genius
[03:14.22]and all without studying a single rule!
[03:19.00]Typically,four-year-olds know some 15,000 words
[03:25.01]and can form very sophisticated sentences.
[03:29.82]Even their mistakes are very logical:
[03:34.49]"I saw two mans" or "We goed to gramma's house."
[03:41.07]So,how does this all happen?
[03:45.28]Well,there are several conflicting theories about language acquisition
[03:51.78]but unfortunately,
[03:54.79]there just isn't time to discuss them today,
[03:59.57]so we'll take them up in Wednesday's class.
[04:03.96]In the meantime,please read Chapter Eight in your textbook.
[04:09.44]See you Wednesday.
