说明 作介词的宾语 作形容词的宾语 it 作形式宾语 例句 Our success depends upon how well we can cooperate with one ano-ther.我们的成 功取决于我们互相合作得有多好。 I am afraid (that) I've made a mistake.恐怕 我犯了个错。 We heard it that she would get married next month.我们听说她下个月打算结婚。
二、宾语从句 宾语从句是在复合句中作宾语的名词性从句，通常放在主 句谓语动词(及物动词)或介词之后。
说明 例句 由 that 引导的宾语从句(that I heard (that) he joined the army.我听说 他参军了。 通常可以省略) 作动词 由 what, whether/if, when, 的宾语 where 等引导的宾语从句 She did not know what had happened.她 不知道发生了什么。 She told me that she would accept my 动词＋间接宾语＋宾语从句 invitation.她告诉我她将接受我的邀请。
It doesn't matter whether he is right or not.(正) Whether he is right or not doesn't matter.(误)
含主语从句的复合句是 Is it likely that it will rain in the evening? (正) 疑问句时，主语从句不 Is that it will rain in the evening likely? (误) 可提前
第九讲 名词性从句
名词性从句是历年高考的重点和难点，也是热点。名词性 从句相当于名词，可作主句的主语、宾语、表语和同位语。因 此，名词性从句可分为主语从句、表语从句、宾语从句和同位 语从句(见下表)。
名词性从句
主语从句 宾语从句 表语从句 同位语从句
连接词
用 that, who, whether/if, what (＝the thing that)等连接词引导。 用 that (可省略), if, whether (or not), what
三、表语从句 表语从句是在复合句中作表语的名词性从句，放在系动词 之后，一般结构是“主语＋连系动词＋表语从句”。可以接表 语从句的连系动词有 be, look, remain, seem 等。引导表语从句的 引导词 that 一般不省略。另外，常用的含有表语从句的结构还
有“The reason why...is that...”和“It is because...”等。如：
否定前移(若主句主语为第一人 称，且谓语动词为 think, consider, suppose, believe, expect, fancy, guess, imagine 等，其后的宾语从 I don't think this dress fits you well.我认 为这件衣服不适合你穿。 句若含有否定意义，一般要把否 定词转移到主句谓语上，从句谓 语用肯定式)
语动词之前或由形式主语 it 代替，而本身放在句子末尾。
1．用 it 作形式主语的结构 结构 It is＋名词＋主语从句 常见句型 It is a fact that...事实是„„/It is n honor that...非常荣幸„„/It is common knowledge that...„„是常识
同位语从句在句子 中的位置
五、whether, if(是否)引导名词性从句的区别 1．句首引导主语从句或出现 or not 时，只能用 whether。 2．if 不能引导表语从句。 3．if 不能引导介词后的宾语从句和同位语从句。 4．宾语从句是否定句只能用 if。
5．discuss 后的宾语从句只能用 whether 引导。
(＝the thing which)等连接词引导。 用 that (一般不省略), whether, what (＝the
thing which)等连接词引导。 用 that (常指代 news, thought, idea 等词), whether 等连接词引导。
一、主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓
It is natural that...„„很自然/It is It is＋形容词＋主语从句 strange that...奇怪的是„„
续表 结构 常见句型 碰巧„„/It appears that...似乎„„ It is reported that...据报道„„/It has been
It＋不及物动词＋ It seems that...似乎„„/It happened that...
