2019年高考英语总复习核心突破课件:第一部分 语法知识 第十五章 It 用法(共27张PPT)

【知识点评】 1.It is kind (of sb.) to do sth.不定式的逻辑主语是由of引 起的,主句中的形容词必须是能表示逻辑主语特征的褒义 或贬义的形容词。常见的词有bad,brave,careless, clever,cruel,foolish,good(好心的),honest,lazy, naughty,nice(有教养的),modest(谦虚的),polite,rude, silly,stupid,wise,wrong(错误的)等。这个句型可以改写为 sb.is kind to do sth.。如:It is kind of you to say so. =You are kind to say so.
2.It is necessary (for sb.) to do sth.不定式的逻辑主语是 由for引起的,主句中的形容词通常是表示重要性、紧迫性、 频繁程度、难易、安全等情况的中性形容词。常见的形 容词有important,impossible,dangerous,hard, difficult,pleasant,unusual等。
【随堂精练】 ( )2.It’s a great honor for me to visit your country. A.to invite B.inviting C.having invited D.to be invited
【答案】D
(三)it作形式宾语 不定式、动名词短语或名词性从句作宾语时,如果后面 带有宾语补足语,常用it作形式宾语,而把真正的宾语(不定 式、动名词短语或名词性从句)放在宾语补足语后面。 句型:主语+谓语动词+it+宾语补足语(名词/代词/形容 词)+真正的宾语
【知识点评】 1.it虽然不是考试的重点,但是它是一个常用词,出现的 频率高,用法多,突出的作用是指代,可以指代事物、群体、 经验、活动等,可以代替一个词、词组或整个句子,以免重 复。比如That wasn’t where you had dinner,was it?it就指 代了前面的句子。 2.it也可指代婴孩或性别不详的人。Who is it?未见具 体人,不同于Who is that?见到具体某人,但不相识。 3.it用作非人称代词的主语,表示气候、天气、温度、 时间、地点、距离等或虚指的情境。
