2014届高考英语临考冲刺语法讲解：it用作形式主语代替动名词主要

用于哪些句式

it用作形式主语代替动名词的用法主要见于以下句式：

1.It is no use(no good, fun, great fun, a new experience, a great honour, etc)doing sth。如：

It’s no use shouting at him—he’s deaf.向他叫喊是没有用的——他耳聋。

It has been a great honour your coming to visit us.你来看望我们是极大荣幸。

2.It is good(nice, useless, interesting, pleasant, tiring, etc)doing sth。如： It is useless speaking.光说没有用。

It was pleasant sitting there.坐在那里很愉快。

It’s so nice sitting here with you.和你坐在一起真是愉快。

第二篇：2014届高考英语临考冲刺 语法讲解 关于分词作状语的逻辑主语问题

2014届高考英语临考冲刺语法讲解：关于分词作状语的逻辑主语问题 有这样一道题，涉及分词作状语时的逻辑主语问题：

Finding her car stolen, _________.A.a policeman was asked to helpB.the area was searched thoroughly

C.it was looked for everywhereD.she hurried to a policeman for help

【分析】此题最佳答案选D，因为句首用作状语的现在分词短语finding her car stolen的逻辑主语应是“她”，而不是 a policeman, the area, it 等，按照英语语法，在通常情况下，非谓语动词用作状语时，它的逻辑主语应与句子主语保持一致，所以最佳答案为D。请再看类例：

(1)To master a foreign language, _________.A.the school needs a foreign teacherB.a good teacher is needed

C.a lot of practice is neededD.one must have a lot of practice

【分析】此题答案选D，因为 to master a foreign language 的逻辑主语应是 one，而不是其他。

(2)_________ many times, he still didn’t understand it.A.Having been toldB.Though to be told

C.Having toldD.He was told

【分析】此题答案选A，因为根据句意，he 与 tell 应是被动关系；另外，从时间上看，应该是“被告诉”在先，“没有理解”在后，故要用 having been told 这一现在分词的完成被动式。注意不能选D，因为 He was told 与he still didn’t understand it 这两个简单句之间缺乏必要的衔接关系(参见下一题)。

(3)_________ many times, but he still didn’t understand it.A.Having been toldB.Though he was told

C.To have been toldD.He was told

【分析】此题答案选D，句中的并列连词 but 表明整个句子为并列句，同时表明 but 前应是一个独立的句子，而不能是一个非谓语动词短语(所以不能选A或C)，又因为 though 为从属连词，用以引导让步状语从句，它与连接并列句的并列连词 but 不“兼容”，所以也不能选B。

第三篇：2014届高考英语临考冲刺 语法讲解 非谓语动词作主语时的主谓一致

2014届高考英语临考冲刺语法讲解：非谓语动词作主语时的主谓一致 非谓语动词(主要指不定式或动名词)作主语时，谓语动词通常用单数。如：
