8、ed teacher. 与一位有经验的老师讨论这个问题是有必要的。 2、常用不定式做主语的句型有： 2.1 Its difficult (important, necessary) for sb. to do 2.2 Its kind (good, friendly, polite, careless, rude, cruel, clever, foolish, brave) of sb. to do. 3、常用动名词做主语的句型有： Its no good (use, fun) doing. Its (a) waste of time ones doing. 非谓语动词3Its worth
9、while doing. （二）不定式、动名词、分词做表语： 1、不定式做表语常表示谓语动词所表示动作之后发生的动作。 His teaching aim of this class is to train the students speaking ability. 他这节课的教学目的是要训练学生说的能力。 2、动名词做表语是对主语内容的解释，这时主语与表语位置可以互换，动名词常用于口语中。 Its full-time job is laying eggs. 它的（指蚁后）的专职工作是产卵。 3、现在分词做表语表示主语的性质与特征；进行时表示正在进行的动作。 The task of this
10、class is practising the idioms. （现在分词做表语） With the help of the teacher, the students are practising the idioms. （现在进行时） 4、常用作表语的现在分词有：interesting, amusing, disappointing, missing, puzzling, exciting, inspiring, following 等。现在分词表示进行与主动。 The joke is amusing .这笑话很逗人。 The problem is puzzling. 这个问题令人不解。
11、5、过去分词作表语表示主语所处的被动状态或完成某动作的状态。而被动语态表示主语所承受的动作。 The village is surrounded by high mountains.（过去分词做表语） The enemy was surrounded by the Red Army.（被动语态） He is well educated.（过去分词做表语） He has been educated in this college for three years.（被动语态） 常用在句中做表语的过去分词有： 非谓语动词4used, closed, covered, interested, foll
12、owed, satisfied, surrounded, done, lost, decided, prepared, saved, shut, won, completed, crowded, dressed, wasted, broken, married, unexpected 等。 6、注意如下动词的现在分词与过去分词用法不同： interest（使感兴趣），surprise（使吃惊），frighten（使害怕），excite（使兴奋），tire（使疲劳），please（使满意），puzzle（使迷惑不解），satisfy（使满意），amuse（使娱乐），disappoint（使失望）
13、，inspire（使欢欣鼓舞），worry（使忧虑） 它们的现在分词常修饰物（有时修饰人），表示主动，过去分词常修饰人，表示被动（包括某人的 look、voice 等）。例如： Climbing is tiring. 爬山很累人。 They are very tired. 他们很疲劳 After hearing the exciting news, he gave a speech in an excited voice. (三) 不定式与动名词做宾语： 1、下列动词跟不定式做宾语： want, wish, hope, expect, ask, pretend, care, decide, h
