表语从句两大问题思维导图模板大纲
1、that引导表语从句
结构:The fact/truth/chance/result/reason/cause+is that,其中that不做成分,可以省略。
2、whether引导表语从句
在表语从句中,需表示是否之意时,只能使用引导词whether而不能用if
3、连接代词(what,who等)和连接副词(when,where,how)引导的表语从句,语序应该为陈述句语序、非疑问句语序,而且这些连接代词和连接副词在句子都作成分。
The town is no longer what it used to be
4、because和why引导表语从句
主要区别在于because用于结果已于前述,需要补叙原因时,也即“先果后因”的倒叙法;why则用于原因已于前叙,需进一步说明其结果的情况,也即“先因后果”的倒叙法。
He didn't come to school yesterday that was because he was ill.
还有一些固定用法:(1)The reason why .....is that....(2)The cause is that....
5、as if/though引导表语从句
在look,seem,appear,feel,smell,sound,taste等系动词之后常可接有as if/though引导的表语
It seems as if it will to rain.
6、as引导表语从句
The main reasons are as follows.
1、在由as if/though 引导表语从句中,若其内容是一种假设或与事实不符,则需要用虚拟语气
The elephant feels as if it were a wall.
2、当suggestion,order,proposal,demand名词后接表语从句时该从句谓语动词多用should+动词原形,其中should可省略。
Their suggestion is that our choice(should) be incorrect.
