托福阅读中长难句的分析和理解(在线收听

   响学生在托福阅读的理解,尤其是在句子简化题。这次题目解析针对于TPO的一个长难句:

  Sediments are also dropped where a river slows on entering a lake or the sea, the deposited sediments are on a lake floor or the seafloor at first, but will be located inland at some future date, when the sea level falls or the land rises; such beds are sometimes thousands of meters thick.
  难句类型: 复杂修饰+插入成分本句的主句结构应当是Sediments are also dropped,but will be located inland at some future date; such beds are sometimes thousands of meters thick. 这是一个由分号隔开的并列句,分号前面的句子结构比较复杂,Sediments are also dropped ,后面跟了一个由where引导的状语从句,紧接着这个状语从句又加上了一个插入结构, the deposited sediments are on a lake floor or the seafloor at first, 然后才开始进行转折but will be located inland at some future date, 但是马上又跟上了一个由when 引导的状语从句。分号后面的半句比较简单 such beds are sometimes thousands of meters thick.同学们面对这样的句子一定要先找主干,把状语从句、插入结构纷纷跳过,从纷繁复杂的句子中找出主干来,才能不被ETS出题人改写的句子所迷惑。
  译文:
  当河流汇入湖泊和海洋的时候也会有沉淀,这些沉淀最初在湖底或海底,但将来海平面下降或者陆地崛起时,它们就会分布于内陆,通常厚达几千米。
  意群训练:
  Sediments are also dropped  where a river slows on entering a lake or the sea,  the deposited sediments are on a lake floor or the seafloor at first,  but will be located inland at some future date,  when the sea level falls or the land rises;  such beds are sometimes thousands of meters thick.
