? ? 托福閱讀長難句分析
?我們來看一個例子。
According to conventional theory, yawning takes place when people arebored or sleepy and serves the function of increasing alertness by reversing, throughdeeper breathing, the drop in blood oxygen levels that are caused by the shallow breathingthat accompanies lack of sleep or boredom.
第一步:分析結構
并列句:Yawning takes place…and serves ….
并列結構前后對稱,如名詞與名詞詞組并列,動詞與動詞并列,從句與從句并列。
Serves是動詞單數(shù),則并列動詞為takes place而非are。

第二步,拆分主干
“Yawning” 為句子主語
takes place + serves ”為謂語
“the function of increasing alertness” 為serves后的賓語。
第三步:還原修飾
“by recersing the drop in blood oxygen levels”修飾”increasing alertness”
“through deeper breathing”修飾”reversing”
“That are caused by the shallow breathing” 修飾“the drop in blood oxygen levels “
“that accompanies lack of sleep or breedom”修飾“shallow breathing”
句子翻譯為:
根據傳統(tǒng)理論,當人們無聊或者厭倦時就會打哈欠,打哈欠可以通過逆轉血液中氧含量的下降來達到提高警覺性的效果。警覺性可以通過深呼吸逆轉血氧含量的下降實現(xiàn),而血氧含量的下降是通過伴隨睡眠缺乏的淺呼吸導致。
讀句子是先讀短,再讀懂,最后讀長。只要按照這三步操作,再長的句子也能朗朗上口,一遍讀懂。希望在以后閱讀中,大家把TPO中長難句及時整理下來,反復閱讀,多加復習。
搞定了長難句才能搞定閱讀,搞定了閱讀,聽力也會簡單,就有更多時間搞口語和寫作,托福100+指日可待,只要你想,沒什么不可以!!!
