人教版初三第一学期英语unit2语法讲解:I think that mooncakes
一、宾语从句
We know him. 简单句
We know he likes English. 宾语从句
结论:宾语从句就是由一个句子来构成主句的宾语
宾语从句三要素:连接词、语序、时态
连接词:
1).陈述句→that (that 在句中无词义,在从句中不能充当句子成分,在口语中往往被省略。)
2).一般疑问句→if/whether(主句 + if / whether + 由一般疑问句变成的陈述句形式)
3).特殊疑问句→原有的特殊疑问词+句子剩余部分的陈述句形式
语序:
陈述句语序(主句 +连接词 +主语 +谓语 +其他成分.)
时态:①当主句是一般现在时,从句用该用的时态(即从句的时态不受影响)
②当主句是一般过去时态,从句必须用过去的某一时态。
1).The teacher says ,“We’ll have exams next Friday.”
→The teacher says (that ) we’ll have exams next Friday.
The girl said,“I can help him.”→The girl said (that) she could help him.
人称的转换规律:一随主,二随宾,三不变。
特别强调:If 与whether 的区别(不可替代的情况)
注意:
宾语从句的否定转移:如果主句的谓语动词是 think, believe, guess 等,而且主句的主语又是第一人称时,它后面接的宾语从句的否定词通常要前移到主句中,即否定主句中的动词,而从句用肯定形式.(主语为第一人称,否定在主句,翻译在从句。)
二、感叹句
表示惊讶、赞美、喜悦、愤怒等情感的句子,通常由what或how引导。
常见结构:
1)What a/an+形容词+可数名词的单数(+主语+谓语)!
2)What+形容词+可数名词的复数(+主语+谓语)!
3)What+形容词+不可数名词(+主语+谓语)!
4)How+形容词或副词(+主语+谓语)!
5)How+主语+谓语! (句子)
