So he didn't just learn water.
而他并不只是學(xué)會了水
Over the course of the 24 months, the first two years that we really focused on,
在24個月里，在最初的2年里，這才是我真正關(guān)注的
this is a map of every word he learned in chronological order.
這里有一張圖按照時序列出了他所學(xué)到的詞匯
And because we have full transcripts,
因為我們有全部的記錄
we've identified each of the 503 words that he learned to produce by his second birthday.
我們?yōu)樗絻蓺q前學(xué)會的503個單詞都做了辨認(rèn)和分析
He was an early talker. And so we started to analyze why.
他算是說話早的。所以我們開始分析其原因
Why were certain words born before others?
為什么有些詞他學(xué)得早
This is one of the first results that came out of our study a little over a year ago that really surprised us.
這是其中的一個研究結(jié)果，是一年多前出來的，讓我們很吃驚
The way to interpret this apparently simple graph
解讀這張看似簡單的圖表的方式
is, on the vertical is an indication of how complex caregiver utterances are based on the length of utterances.
是橫坐標(biāo)表示，照顧者的話語復(fù)雜程度基于話語的長度
And the axis is time. And all of the data, we aligned based on the following idea:
縱坐標(biāo)代表了時間。所有的數(shù)據(jù)我們都用下述的方法排列：
Every time my son would learn a word,
每次我們發(fā)現(xiàn)兒子學(xué)了一個新的詞
we would trace back and look at all of the language he heard that contained that word.
我們就會回溯他聽過的這個詞的所有的語言記錄
And we would plot the relative length of the utterances.
然后我們繪制這些語言的長度
And what we found was this curious phenomena, that caregiver speech would systematically dip to a minimum,
我們發(fā)現(xiàn)了一個奇特的現(xiàn)象，照顧者的講話會系統(tǒng)地將語言簡化
making language as simple as possible, and then slowly ascend back up in complexity.
簡化到最簡單的程度，然后漸漸地回升到更復(fù)雜的句子
And the amazing thing was that bounce, that dip, lined up almost precisely with when each word was born -- word after word, systematically.
而驚奇的事是這種回升和下降，正好精確的吻合了每個詞的誕生過程--一個詞接一個詞，很有系統(tǒng)規(guī)律
So it appears that all three primary caregivers -- myself, my wife and our nanny --
似乎三個主要的照顧他的人--我，我妻子，和我們的保姆--
were systematically and, I would think, subconsciously restructuring our language
都是有系統(tǒng)的，我想，也是下意識的重新構(gòu)建我們的用語
to meet him at the birth of a word and bring him gently into more complex language.
去迎合他的新的詞匯的誕生，帶他漸漸學(xué)習(xí)更為復(fù)雜的語言。
