復(fù)雜的分割結(jié)構(gòu)（插入語）的理解 例226

例226　Human beings have agreed, in the course of centuries of mutual dependency, to let the various noises that they can produce with their lungs, throats, tongues, teeth, and lips systematically stand for certain happenings in their nervous systems.

【結(jié)構(gòu)分析】句子的主語是Human beings，動詞是have agreed，動詞和賓語之間增加了插入語，也就是in the course of centuries of mutual dependency，后面是不定式to let，賓語是the various noises，后面加上定語從句that they can produce with their lungs, throats, tongues, teeth, and lips，再加上賓語補足語stand for certain happenings in their nervous systems，是個let sth do這樣一個結(jié)構(gòu)。

【亮點回放】此句話的亮點在于插入語的成功使用，而且里面還有很復(fù)雜的定語從句。

【核心詞匯】

mutual dependency　相互依賴

systematically　系統(tǒng)地

stand for　代表

certain happenings　某些狀況

nervous systems　神經(jīng)系統(tǒng)

【參考譯文】人類在相互依賴生存的幾個世紀(jì)中慢慢形成一致觀點，也就是他們可以用肺部，嗓子，舌頭，牙齒，嘴唇所產(chǎn)生的聲音來代表神經(jīng)系統(tǒng)中發(fā)生一些情形。
