1、非谓语动词与从句之间的关系及转换非谓语动词与从句间的相互关系及转换：英语中的非谓语动词是整个英语语 法当中非常重要的部分，也是英语学习的一个难点。非谓语动词作句子成分时与 相应的从句有着千丝万缕的联系，它们之间可以有条件的进行相互转换。一、非谓语动词与从句的相互关系（一）不定式和分词作定语相当于定语从句不定式通常位于被修饰名词后。与该名词构成逻辑上的动宾关系。如果不定 式与所修饰名词在意思上是被动且逻辑上的主语不出现时，要用不定式的被动 式，与所修饰名词构成逻辑上的主谓关系。分词作定语时，单个分词置于名词之前，分词短语置于名词之后，与名词构成主谓关系或被动主谓关系。定语从句和不定式、分词作定语

2、只是两种不同的表达方式，本质是相同的。例如：I have many letters to type .（动宾关系）f I have many letters which I should type .I have many letters to be typed .（被动主谓关系）f I have many letters which are to be typed by others .The standing people shouted at the dean .（主谓关系）（二）不定式和分词作状语相当于状语从句1. 不定式多作目的状语和结果状语.故可以转化为相应的目的状语从句和结果 状

4、in the army .2. 分词作状语可以表示时间、原因、条件、方式和让步等，相当于相应状语的从句。如果分词的逻辑主语与主句主语一致，则用现在分词；如果分词的逻辑主语与主句是被动关系且主语一致时，则用过去分词。分词作状语时，如果其带有逻辑的主语，称为分词的独立主格结构。分词的逻辑主语与句子的主语无语法联 系。例如：Seeing those pictures . he could nt help thinking of the un forgettable days in New York .（时间状语）f When he saw those pictures . he couldn t h
