2022届高考英语二轮复习:名词性从句 导学案
一、名词性从句的定义
在复合句中起名词作用的从句叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中的功能可以是主语、宾语、表语、同位语等,因此,根据它的这些语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
1. Whether he will go abroad has not been decided.
2. I expect that he will come.
3. The most important thing is that we must concentrate on study.
4. The news that Zhang ziyi will come to our city surprised us.
引导词及其词义 用法(在从句中充当什么成分)
从属连词 that, whether/if(是否)as if (似乎,引导表从) 只作连词,不充当句子成分
连接代词 who/ whoever, whom/whomeverwhose, which/whicheverwhat/whatever 既起连词作用,又作从句的主语,宾语,表语或定语
连接副词 when/wheneverwhywhere/whereverhow/however 作状语
引导名词性从句的引导词归纳起来可分为以下三类。

3、英语短文。
The main reason why some students prefer to gain information on the Internet is that they think it convenient. In addition, there’s no denying the fact that they can get accurate answers to questions quickly. However, what I want to stress is that it is likely that students will lose interest in thinking. In my opinion, measures must be taken to solve the problem. For example, what teachers and parents should do is to encourage students to finish their homework on their own.
