怎样判断句中动词是谓语还是非谓语

  在动词填空中,首先要判断句中的动词是谓语还是非谓语,特别是在长难句中更是如此.
下面通过两个句子来帮助同学们分析和破解这一难题.下面这两道练习题均来自高一年级期末动词复习单词拼写专题,经检查答案发现,答对率都是很低的.
  1.At present the terrorists weren't concerned about the request concerning how the government officials _______(乞求) for less cruelty would be released .
  2.Anyone hearing about the escaped *er _______(被判刑) to 10 years in * will be personally rewarded by the judge with money from the fund which has been created not long ago.
  学生答题情况:1 误填 begged 2.was sentenced (正确答案应该是:1.begging;2.sentenced)显然,学生所填的这两个答案都是错误的,其根本原因就是因为句子太长而搞不清楚句中要填的是谓语动词还是非谓语动词.既然方向都不清楚,那么“目的地”就肯定是错的了.
  解题思路:1.先分析句中所缺的是谓语还是非谓语.在判断前,必须搞清楚也原句的主谓结构,主语是the terrorists 谓语部分是weren't concerned about ,宾语是the request,concerning how …一直到句末是定语,在concerning后 又接了一个从句,从句中的主语是the government officials ,谓语是would be released .由此可见,句中并不缺谓语,填上去的动词应该是一个作定语的非谓语动词,因此要填begging;
  2.该句的主语是:Anyone,hearing about…是定语 ,谓语是will be … rewarded ,后面which 引导的是一个定语从句;由此可见,句中并不缺谓语,缺的正是非谓语.根据句意应填上表被动意义的过去分词,在此作后置定语.
  小结:当遇到一个长难句时,首先要学会“削枝留干找主谓”,确定主谓再找附加成份,这样句中的动词是谓语还是非谓语就一目了然了.
