第五节:名词性从句 教案
一、 英语句子的分类 单句:由一套主谓宾构成的句子。 复句:有两套主谓宾构成的句子。复句又分为 并列句 复合句 二、 并列句的用法 结构:句子+并列连词+句子 常见的并列连词: 表示并列关系:and both?and neither?nor not only?but also 表示转折关系:but yet still however nevertheless 表 示 选 择 关 系 : or or else( 否 则 ) otherwise either ? .or whether?.or 表 示 因 果 关 系 : for then thus so therefore consequently 三、 主从复合句的句法 1. 主从句主句专一原则 一个句子只有一个主句且没有连接词 一个句子有 n 个分句,只有 n-1 个连接词。 故 although 不与 but 连用 because 不与 so 连用 2.主从复合句的分类 名词性从句:主语从句、宾语从句、表语从句、同位语从句 三大从句 形容词性从句:定语从句 副词性从句:状语从句

名词性从句详解
一、 如何判断从句是名词性从句的哪一类 看从句(不是连接词)在句子中做什么成分。 如:从句作主语:主语从句 从句作宾语:宾语从句(放在及物动词的后面或者介词的后面) 从句作表语:表语从句(放在系动词后面) 从句作同位语(异名同物) :同位语从句。 (放在名词后) 常 见 的 同 位 语 从 句 的 名 词 : idea/fact/promise/message/word ( 消 息)problem/question/suggestion/ /possibility 举例:What he said at the meeting sounded reasonable. We didn’t know what my son has done to my computer. My suggestion is that we should leave the matter alone. He didn’t keep his promise that he would come to help us.

名词性从句常见的连接词: 不充当句子成分的连接代词 连接词 引导的从句 在从句中充当的成分 That(无意义起连接作用) 四种从句都行 不充当句子成分 Whether(是否) 四种从句都行 不充当句子成分 If(是否) 只引导宾语从句 不充当句子成分 注意: 1.若谓语动词是“怀疑(doubt) ”和“想知道(wonder) ”时,主句是肯定句, 从句用 if/whether ,主句是疑否句从句用 that . 2.whether 能与 or (not)连用,表示无论?还是?. If 不能 whether 能放句首,if 不能 3.所有的从句都用陈述语序 充当句子成分的连接代词 连接词 What(什么、所?的) Whatever(任何事物 不管什么) Who whoever Whom whomever Which(哪一个)有明确的范围选择 whichever whose 引导的从句 四种从句都行 四种从句都行 只引导主、宾从句 不能引导同位语从句 主 在从句中充当的成分 主 宾 表 主 宾 宾 定

充当句子成分的连接副词 连接词 When where why How 引导的从句 四种从句都行 四种从句都行 四种从句都行 四种从句都行 在从句中充当的成分 时间状语 地点状语 原因状语 方式状语

补充:
有关 that 的几个用法
1. That+宾表从句时,that 可以省略,而且常常省略。That+同位语从句时 that 不可省略。 2. it + seem/appear/happen/occur + that?????????? 此时下划线的部分是主语,但是主语太长,所以用 it 代替,it 叫形式主语

如何做题: (做题三部曲)
3. 分清从句类型 4. 看从句中缺少什么成分,缺什么成分就选什么成分。 5. 若有多项符合前两条标准则看意思。
