[ 高二语法 ] 非谓语动词 非谓语动词是高中英语语法教学的重要内容之一,也是教和学的一大难点。同时,还是高考每年必考的 内容之一。 一、作主语 非谓语动词包括动词不定式、动名词、分词 三种。能够作主语的 是不定式和动名词。 1. 动名词为泛指,表示抽象的、笼统的、习惯性的行为; 不定式则表示特指,指具体的、一次性的或尚未发生 的行为。 Collecting information is very important to businessmen. To collect information is the most difficult job for us to do next. 2. 在 It is no use /no good 等句型中应用动名词。例如:It is no use ( no good, no point, no sense, a waste of time ) + doing sth. It is good ( nice, interesting, useless) + doing sth.There is no point ( use, sense, good) + doing sth.It’s no use crying over spilt milk. 后悔没有用。It’s simply a waste of time and money playing games.There is no point in my going out to date someone. 现在让我出去和别人拍拖没有用。I find it no good advising him to go with us. 我发现建议他和我们一起去美什么好处。 在“ have difficulty ( trouble, problem, pleasure, a difficult time (in) doing sth. 结构中, 后接动名词; 但注意 take the trouble to do sth. , have no time to do sth. 后接不定式 .I have some difficulty in persuading him.I worked so late in the office last night that I hardly had time to catch the last bus. 二、作表语 不定式、动名词、现在分词和过去分词均可用 作表语。 不定式与动名词作表语时的区别与作主语时相同。例如: My job is teaching English. ( 泛指,多次性抽象行为 ) Your task is to go and help the farmers. ( 特指,一次性具体行为 ) 同时,需要注意对等原则, 即: 表语使用不定式还是动名词应与主语保持一致。 例如: Seeing is believing . To see is to believe. 不定式、动名词作表语时相当于名词,而分词作表语时相当于形容词。现在分词表示主动,过去分词表示被动。例如One of the good exercises is climbing the mountain.( 相当于名词,...
