不定式和动名词作主语的区别作表语的区别 一、不定式和动名词作主语的区别 1、动名词作主语通常表示抽象动作;而不定式作主语表示具体动作。 2、名词作主语时,通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。 3、不定式做主语,一般用it当形式主语,把作主语的不定式短语后置。 高中英语单词表3500词必背 英语单词记忆法 人教版初中英语单词 二、不定式、动名词和分词作表语的区别 1、不定式作表语 1)不定式作表语一般表示具体动作,特别是表示将来的动作。 2)如果主语是不定式(表示条件),表语也是不定式(表示结果)。 3)如果主语是以aim, duty, hope, idea, job, plan, problem, purpose, thing, wish等为中心的名词,或以what引导的名词性从句,不定式作表语是对主语起补充说明作用。 2、动名词作表语:动名词作表语,表示抽象的一般性的行为。 (注)动名词作表语时与进行时态中的现在分词形式相同,但其所属结构迥异,进行时态说明动作是由主语完成的。动名词做表语,说明主语的性质或情况。 3、分词作表语 分词做表语有两种情况,一种是现在分词做表语,一种是过去分词做表语。 这类词常见的有: interesting –interested,exciting –excited,delighting –delighted,disappointing --disappointed encouraging –encouraged,pleasing –pleased,puzzling –puzzled, satisfying ---satisfied,surprising –surprised,worrying --worried 题1: Since 1995, ______ people call the Year of the Internet, the world has turned flat thanks to the net work.. A. which B. when C. in which D. by which time 答案: A 详解:______ people call the Year of the Internet为定语从句,其先行词为1995。此处1995为call的宾语,所以选which。 题2: The old town has narrow streets and small houses ______ are built close to each other. A. they B. where C. what D. that 答案: D 详解:_____are built close to each other 是定语从句,其先行词为narrow streets and small houses。从句中缺少主语指物,因此用that。句意:这个老城镇拥有建的彼此靠近的狭窄的街道和狭小的房屋。 题3: We went to the West Lake yesterday, , not surprisingly, was crowded with visitors from all over the world. A. where B. which C. that D. when 答案: B 详解:第一个逗号之后是一个非限制性定语从句,其先行词为the West Lake。把从句中的插入语not surprisingly删去之后,就可明显地看出从句缺少主语,所以选which。 题4: Between the two parts of the concert is an interval, _______ the audience can buy ice-cream. A. when B. where C. that D. which 答案: A 详解:_______ the audience can buy ice-cream是定语从句,其先行词为interval。因为从句缺少时间状语in the interval,所以选when。 题5: The time is not far away ________ modern communications will become widespread in China’s vast countryside. A. as B. when C. until D. before 答案: B 详解:因为先行词是the time,且在定语从句中作状语,所以用when引导。此题的先行词与定语从句被主句谓语分开了,要善于辨别。 ![]() |
