表语从句一、表语从句的概述用来作表语的从句叫作表语从句。表语从句说明主语是什么或者怎么样，位于系动词之后。可以接表语从句的系动词有be，seem，lk，sund，taste，feel，remain，appear等。It seems as if it were spring already．春天似乎已经来了。
二、引导表语从句的常见连接词常见的有连接代词 wh，which，whatever 等，连接副词 hw，why，whenever 等，从属连词 as，that，whether，because等。1．that引导表语从句that引导表语从句时仅起连接作用，无任何意义，在从句中不作任何成分，通常可省略。The truble is that she has lst his address．麻烦的是她弄丢了他的地址。My suggestin is that we shuld tell him．我的建议是我们应该告诉他。
2．whether引导表语从句whether引导表语从句时起连接作用，意为“是否”，但在从句中不作任何成分，也不可省略。The questin remains whether they will be able t help us．问题还是他们是否能帮我们。
[温馨提示]if不能引导表语从句。3．连接代词引导表语从句连接代词what，wh，whm，which等引导表语从句时，除了在句中起连接作用外，在从句中还可充当主语、表语、宾语等成分，它们都不可省略。He is n lnger what he used t be．他已经不再是以前的他了。The prblem is wh is really fit fr the hard jb．问题是谁才真正适合做这份艰苦的工作。
4．连接副词引导表语从句连接副词where，when ，why ，hw等引导表语从句时，除了在句中起连接作用外，在从句中还分别充当地点、时间、原因、方式状语，它们都不可省略。The prblem is hw we can find him．问题是我们如何才能找到他。That's where yu are wrng．那就是你不对的地方。
5．because，as if/as thugh等引导表语从句because引导的表语从句常见于“This/That/It is/was because...”句型中。as if/as thugh引导的表语从句常置于系动词lk，seem，sund，be，becme等后面。That's because yu can't appreciate music．那是因为你不会欣赏音乐。It sunds as if smene is kncking at the dr．听起来好像有人在敲门。
[温馨提示]①why和because引导的表语从句
I didn't phne her，and that's why she gt angry with me．(强调“没打电话”这一结果)我没有给她打电话，那就是她生我气的原因。I didn't phne her，and that's because I gt angry with her．(强调“生气”这一原因)我没有给她打电话，那是因为我生她的气了。
②that与what引导的宾语从句what既引导表语从句，同时又在从句中作成分(主语、宾语、表语等)。这时what相当于all that/everything that，常译成“……的(东西、事情、话等)”；而that只起连接作用，本身无实际意义，在从句中也不充当任何成分。What is the mst imprtant is that we shuld take sme effective measures t prtect the envirnment．最重要的是，我们应该采取一些有效的措施来保护环境。China is becming strnger and strnger．It is n lnger what it used t be．中国正变得越来越强大，不再是过去的样子了。
③表语从句中的虚拟语气在表语从句中，表示间接的命令、要求、请求、建议、决定等，主句中的主语通常是：advice，suggestin，prpsal，request，rder，idea等，从句谓语形式用“shuld＋动词原形”(shuld可以省略)。My suggestin is that we (shuld) start early tmrrw．我的建议是我们明天早点出发。
