2024年初中英语语法专项学习之表语从句及其引导词用法 表语从句引导词及用法总结 根据关联词来区分,表语从句可以分为六种: 一、由that引导的表语从句 The trouble is that he misunderstood me.麻烦的是他误解了我。 有时,引导表语从句的连词that可以省略 The truth is (that) I didn’t finish my term essay. 事实是我没有写完学期论文。 二、由连接代(副)词引导的表语从句 连接代词who, whom, whose, what, which, whoever, whatever, whichever; 连接副词where, when, how, why。 That was what she said this morning in her bedroom.那就是她今天早晨在卧室中说的。 三、由关系代词型的what引导的从句 I want to be a teacher. That’s what I want to be. 我想当老师,那是我的志愿。 四、关联词是连词because 比较下面这两个句子: I was angry. That was because he didn’t understand me. 我生气是因为他不理解我。(表语从句强调原因) That’s why he got fired from that firm.那正是他被公司解雇的原因。(表语从句强调结果) 注意:reason作主语或主语中包含事件的起因时,后面的表语从句表示原因时要用that来引导,而不用because That is why ...是常用句型,其中why引导的从句在句中作表语,该句型通常用于针对前面已经说过的原因进行总结。 1. That is the reason why ...That is the reason why ...与That is why ...是同义的, 但是从语法结构上讲,That is the reason why ...中的why引导的是一个定语从句,将其中的the reason去掉后则与That is why ...结构一样了 2. That is because ...That is because ...也是一个常用句型。 That is because ...句型中,连词because引导的从句作表语, That is because ...与That is why ...之间的不同在于That is because ...指原因或理由, That is why ...则指由于各种原因造成的结果 He did not read Harry Potter last night. That is because he had to help his mother to do the housework. 昨天晚上他没有读《哈里波特》,那是因为他得帮助他妈妈做家务。 五、关联词是从属连词whether, as, as if The question remains whether we can win the majority of the people. 问题是我们能否赢得大多数民众的支持。 六. 使用虚拟语气的表语从句 在表示建议、劝告、命令含义的名词后的表语从句,谓语动词需用“should+动词原形” 表示,should可省略。 常见的词有:advice,suggestion,order,proposal,plan,idea等。 My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。 表语从句: 就是用一个句子作为表语。说明主语是什么或者怎么样,由名词、形容词或相当于名词或形容词的词或短语充当,和连系动词一起构成谓语。 表语从句是名词性从句的一种。 表语从句的基本结构是: “主语+连系动词+关联词+表语从句”。 连接表语从句的连接词有: that, what, who, when, where, which, why, whether, how, whoever,whomever,whichever ,whatever等。 例如:The question is when he can arrive at the hotel. His suggestion is that we should stay calm. ①语序: 从句的语序必须是陈述句语序,即“主语+谓语”这种形式。 ②时态: 当主句是一般现在时或一般将来时的时候,从句可以是任何时态,而当主句是一般过去时的时候,从句,从句时态必须是过去时范围的时态,即(一般过去时,过去进行时,过去完成时,过去将来时)。 ③连接词: 当从句意思完整,主句意思肯定时,连接词用that,且可以省去,当从句意思完整,主句意思不确定或含否定含意时,常用if或whether(是否),当从句意思不完整时,连接词则是代替不完整部分的 ... ...
