主语从句公开课课件
• W___h__e__t_h_er we can go to picnic tomorrow is still a question.
•___T__h__a__t the wounded soldier is still alive is a wonder.
•___T__h__a__t Mr. Zhou will come is certain.
called.
E. It+doesn’t matter (makes no difference, et c.)+连接代词或连接副词引起的主语从句。如：
It doesn’t matter whether she will come or not. 注：在主语从句中用来表示 “惊奇，不相信，惋惜，
理应如此， 要求，建议”等语气时，谓语动词用 “should+ do”
1.What you left a_r_e only several old books.
2.What you said i_s of great importance.
3.Whether he’ll come here i-s not clear.
if /whether 引导的主语从句

如：
It’s no wonder that you have achieved so much success. 真可惜你没出席昨天的讲座。
I_t’_s_a_p_i_ty__th_at you didn’t attend the lecture yesterday
从句—主语从句(英语语法课件)
接下来我们来看看主语 从句中从句引导词的各 种用法
灵活运用
✓ 从属连词 ✓ 连接副词 ✓ 连接代词
灵活运用
that,whether
从属 连词
when, where, how, why
连接 副词
连接 代词
who，what，which， whatever, whichever, whoever
灵活运用
It 作形式主语和it引导强调句的比较
而强调句则不同，它的结构是： It+be+被强调部分+that+从句
强调主语：It is the times that produce their heroes. (时势造英雄) 强调宾语：It is English that Prof.Lin teaches us. 强调状语：It was in shanghai that I saw the film. 判断是否是强调句有一个方法，就是将that以后的“句 子的其余部分”拿出来单独看，看有没有缺成分，缺的 是什么成分，再把谓语动词后面that前面的那部分，带 到你认为缺成分的地方，如果放进去是一句完整的句子 了，那就说明是强调句。
It 作形式主语和it引导强调句的比较
为避免头重脚轻，常以形式主语 it引导从句。 It+形式主语谓语+从句。
例：It is known that... It is shown that... 用it 作形式主语的结构 (1) It is +名词+that从句 It is a fact that … 事实是…… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is +形容词+that从句 It is natural that… 很自然…… It is strange that… 奇怪的是…… (3) it +不及物动词+that从句 It seems that… 似乎…… It happened that… 碰巧…… (4) it is+过去分词+that从句 It is reported that… 据报道…… It has been proved that… 已证实……

主语从句PPTPPT课件.ppt
注意： (1)从句作主语谓语动词常用单数，但如果 what 引导的从句作主语，后跟名词作表语 时，谓语动词则由表语名词的数量决定。 What he told me is true. 他告诉我的是真的。 What he saw were some new comers. 他看见的是些新来的人。
(2)It is said that sb.do sth.的复合句形式可转化为简单句sb.be said to do sth.， 而且在简单句中常考查 to do 的具体形式。 (3)it 引导的强调句与 it 作形式主语的复合句的区别。 it 引导的强调句是用来对句中除谓语外某一成分加以强调，其结构为“It is/was＋ 被强调部分＋that/who...”。如果被强调的主语是“人”，则可用 who 或 that， 如果被强调的部分是其他成分时，必须用 that。 It was I that/who met John in the street yesterday. 是我昨天在街上遇到了约翰。(强调主语) It is a pity that you didn't go to see the film. 你没去看电影很可惜.ppt
