表语从句的常见引导词有哪些
常见的表语从句引导词总共有五类,连词that,whether,连接代词,连接副词,和关系代词what,种类较多,又比较零碎,很容易为学习者们所忽略。但引导词是从句学习中的重中之重,没有引导词,就不能构成从句,因此沪江小编这次就为大家梳理一下表语从句常见的五类引导词。 一.that 当that引导表语从句时,只起连接作用,不在表语从句中充当任何句子成分,但通常不省略,除了在部分口语句子中。 eg. The fact is that he doesn’t really try. The trouble is (that) he is ill. * 当主语是reason时,表语从句要用that连接,而不是because。 eg.The reason why he didn't come was that he missed the train. 二.whether 当表语从句要表达“是否”的含义时,连接词要用whether, 并且绝对不能用if进行替换。 eg.The question is whether the film is worth seeing. 三.连接代词who/whom/whose/which 当疑问代词用来连接表语从句时,既起连接作用,又充当句子成分。 eg.The problem is who we can get to replace her. The quesstion is whom we can trust. 四.连接副词when/where/why/how 当疑问副词来连接表语从句时,既起着连接作用,同时充当句子成分,一般作状语。 eg.The problem is how we can find him. That’s why he didn’t come. 五.关系代词what what引导表语从句时,既起连接作用,又充当句子成分。 eg.I am no longer what I was. That’s what I want to stress. 好了以上就是小编为大家梳理的表语从句五大常见引导词的相关知识点了,内容是不是很丰富呢?不知道大家记住了多少呢?引导词作为从句中不可忽略的部分是各位学习者必须要掌握的重点,而表语从句更是英语中出现的最常见最普遍的从句之一,引导词都是平常会使用到的基础词汇,所以只要掌握规律,就能慢慢地熟悉掌握各类用法了,希望小编为大家准备的内容能给各位提供帮助。 |
