12、grandfather being ill.是独立主格结构。Her grandfather 是现在分词的逻辑主语，而主句的主语是she。)T:Now look at the screen, lets conclude something about the grammar item.1.分词作状语:过去分词的逻辑主语必须和句子的主语保持一致。分词的逻辑主语和句子的主语保持一致的情况下，如果分词和句子的主语之间在逻辑上是被动关系，用过去分词，否则用现在分词。分词短语也可以有自己的逻辑主语，这种结构称为独立主格结构。分词作状语可以相当于一个状语从句。现在分词的被动式，习惯上不作伴随状语。2.分词作
13、表语:一般来说，表示心理状态的动词如excite,interest等都是及物动词，汉语意思不是“激动”“高兴”，而是“使激动”“使高兴”，因而现在分词应该是“令人激动的”“令人高兴的”，过去分词则是“感到激动的”和“感到高兴的”。所以，凡表示“令人的”都是-ing形式，凡是表示“感到”都用-ed形式。换句话说，-ed形式常和人有关，-ing形式常和物有关。look, expression等词作主语时常用-ed形式作表语，但有时要看具体情况。请在下面的几组句中体会他们的区别。The news was very exciting.

16、分词作定语与其修饰词之间是动宾关系或过去分词表示的动作已完成；现在分词作定语表示动作正在发生，与修饰词是主谓关系。 The school to be built is intended for the disabled children.即将要建的学校是为残疾儿童而设的。 The school being built is intended for the disabled children.正在建设的学校是为残疾儿童而设的。 The school built last year is intended for the disabled children.去年建的学校是为残疾儿童而设的。便于记
17、忆-ed形式和-ing形式作表语及作定语时的区别的句子:I am interested in the interesting book.He was excited at the exciting news.The parents were disappointed about their disappointing son.Mr.Smith, tired of the boring speech, started to read a novel.4.作补语:跟分词作宾补的动词有:catch, have,get, keep, hear, find,feel, leave, make,want,
18、 start, notice, observe, watch, set等。在复合宾语中，用现在分词作宾补，说明宾语是动作的发出者，形成逻辑上的主谓关系；用过去分词作宾补，表示宾语是动作的承受者，构成逻辑上的动宾关系。 There was so much noise that the speaker couldnt make himself heard.When he awoke, he found himself being looked after by an old woman.Just now I caught him stealing things from the supermark
