②连接代词(在从句中充当主语、宾语、表语、定语):what(……的事情/东西)、who(谁,指人)、whom(谁,指人,作宾语)、whose(……的,表所属)、which(哪一个,表选择)、whoever(无论谁)、whatever(无论什么)、whichever(无论哪一个); ③连接副词(在从句中充当状语):when(什么时候)、where(在哪里)、why(为什么)、how(如何,怎样)、whenever(无论何时)、wherever(无论何地)、however(无论怎样)。 考●向●破●译 考向 考查表语从句的连接词 1.Experts aren’t sure exactly how dreams work, but what is certain is they are necessary for our mental health and that everyone has dreams. 【答案】that 【解析】考查表语从句。句意:专家们并不完全清楚梦境是如何运作的,但可以确定的是,梦境对我们的心理健康是必要的,而且每个人都会做梦。空处引导表语从句,从句句意完整、成分齐全,应用只起连接作用、无实意的that引导。故填that。 2.Peter showed me that what matters is you convey your own passion so that you excite other people. 【答案】how 【解析】考查表语从句。句意:彼得告诉我,重要的是你如何表达自己的激情,这样你才能激发别人。空处引导表语从句,从句缺少方式状语,需用连接副词how引导。故填how。 3.He feels so happy that he followed his heart when choosing what to do with his life, even though it may not be others expected of him. 【答案】what 【解析】考查表语从句。句意:他感到很开心,在选择自己的生活时,他听从了自己的内心,即使这可能不是别人对他的期望。分析句子可知,be后接表语从句,从句缺少宾语,指物,用连接代词what。故填what。 4.What the doctors really doubt is my mother will recover from the serious disease. 【答案】whether 【解析】考查表语从句。句意:医生真正怀疑的是我妈妈是否能从重病中恢复过来。空处引导表语从句,且根据句意可知,此处表示“是否”,应用whether引导。故填whether。 考点二 考查表语从句连接词的用法(高考高频考点) 知●识●解●构 知识点1 连接词that的用法 核心功能:无实际含义,只起连接作用,不充当从句任何成分;引导的表语从句语义完整,无需补充信息。 大多数情况下可省略(区别于主语从句:主语从句句首that不可省略,表语从句that可省);

My requirement is that you (apologize) to me in public. 【答案】should apologize/apologize 【解析】考查表语从句的虚拟语气。句意:我的要求是你当众向我道歉。根据句意可知,requirement“要求”作主语时,其表语从句需要使用(should)+动词原形的虚拟语气。即apologize动词原形或者在其前加should,构成虚拟语气。故填(should)apologize。 2.The suggestion from the student union is that all classes __________ (organize) a volunteer activity to help the elderly in the nearby community next weekend. 【答案】(should) organize 【解析】虚拟语气(“suggestion + be + that...” 结构中,表语从句需用 “should + 动词原形”,should 可省略)句意:学生会的建议是,所有班级下周末都应组织一次志愿活动,帮助附近社区的老人。主句主语 “suggestion” 表 “建议”,其后表语从句需用虚拟语气,结构为 “(should) + 动词原形”,故填 (should) organize。 考点七 表语从句的常用句型 知●识●解●构 知识点 1 The reason (why/for ...) is that ...

That is he had to help his little sister with her homework. 【答案】because 【解析】考查表语从句。句意:他没有看那部电影。那是因为他必须帮助他的妹妹做家庭作业。分析句子可知,空处引导名词性从句作句子表语,表语从句的成分完整, 且从句内容是对前面的“He did not see the film.”进行解释,因此空处应用because,表示“因为”。故填because。 4. My question is he likes the city center so much. 【答案】why 【解析】考查连接词。句意:我的问题是他为什么这么喜欢市中心。引导表语从句,表示 “为什么”用连接词why。故填why。 考点八 表语从句中的主谓一致、语序及时态问题 知●识●解●构 知识点1 表语从句的主谓一致需根据主句主语和表语从句的具体语境确定。 知识点2 表语从句的语序通常是陈述句语序,即主语在前,谓语动词在中间,其他成分在后。 知识点3 时态和语态:表语从句的时态和语态通常取决于主句的要求。 考●向●破●译 考向 考查表语从句中的时态 1.Dressed up, she looks as if she (be) ten years younger. 【答案】were 【解析】考查虚拟语气。句意:打扮起来,她看上去年轻了十岁。as if引导的表语从句与现在事实相反,使用一般过去时,be动词使用were。故填were。 2.My suggestion is that we (catch) up with the other classes. 【答案】 should catch/catch 【解析】考查虚拟语气。句意:我的建议是我们应该赶上其他班级。在suggestion后的表语从句中,要用虚拟语气,即从句谓语动词用“should+动词原形”,其中should可省略;本句中“that we (catch) up with the other classes”是表语从句,谓语catch up with(赶上)与主语we之间是主动关系,用虚拟语气(should) catch。故填(should) catch。 考点 九 主语从句的易错点 知●识●解●构 知识点1 that vs whether(高频考点) 看从句语义:语义完整(无“是否”含义)→ 用that;语义不完整(有“是否”选择)→ 用whether; 看主句主语:主句主语为reason时,表语从句只能用that,不可用because(易错点); 特殊注意:表语从句中that可省略,whether不可省略,且不可用if替代。 例句对比: His decision is that he will study abroad.(语义完整,用that,可省略) His decision is whether he will study abroad.(语义不完整,表“是否”,用whether) The reason is that he is ill.(正确:主句主语为reason,用that) The reason is because he is ill.(错误:不可用because,需改为that) 知识点2 what vs that(高频考点) that:无含义,不充当从句成分,只起连接作用,从句语义完整; what:有含义(“……的事情/东西”),在从句中充当主语、宾语、表语,从句语义不完整(缺成分)。 例句对比(易错警示): My wish is that he said at the meeting.(错误:从句缺宾语,that不能充当宾语) My wish is what he said at the meeting.(正确:what在从句中作宾语,指代“他说的话”) My wish is that he will come soon.(正确:从句“he will come soon”语义完整,that只起连接作用) 知识点3 whether vs if 表语从句中,只能用whether,不能用if(核心易错点,区别于主语从句“it作形式主语时可换if”),三种常见场景均需用whether: 1. 表语从句表“是否”,无论位置如何,均用whether; 2. 表语从句后接or not时,只能用whether; 3. 表语从句位于介词后(作介词宾语,本质还是表语从句),只能用whether。 例句对比: The question is whether he will come or not.(正确:表语从句+or not,用whether) The question is if he will come or not.(错误:表语从句不能用if) It depends on whether he will agree.(正确:表语从句位于介词on后,用whether) 知识点4 连接代词 vs 连接副词 解题依据:从句缺主语、宾语、表语、定语 → 用连接代词;从句缺时间、地点、原因、方式状语 → 用连接副词(与主语从句完全一致)。 例句对比: The problem is how we will get there.(从句“we will get there”缺方式状语 → 用how,连接副词) The problem is what we will take there.(从句“we will take there”缺宾语 → 用what,连接代词) The question is when we will get there.(从句缺时间状语 → 用when,连接副词) 考●向●破●译 考向 考查表语从句中的易错连接词 1.

That is because he got up late.(他迟到了,那是因为他起晚了。)注意与 because 引导原因状语从句的区别:表语从句中的 because 强调“前文情况的原因”,而原因状语从句中的 because 强调“导致主句结果的原因”。如:He didn't come because he was ill.(原因状语从句,强调生病导致没来) ;He didn't come. That is because he was ill.(表语从句,强调没来的原因是生病) 知识点2 as if / as though:意为“好像,似乎”,引导的表语从句常跟在 look, seem, sound, feel 等感官动词后面。当描述与事实相反的假设时,从句用虚拟语气;描述真实情况时用陈述语气。 考●向●破●译 考向 考查because,as if和as though引导的表语从句 1.My face was burning; this was I was embarrassed about how untidy the house was. 2.Indoor plants might look as they just sit around not doing much, but in many ways they are the unsung heroes of the home.   3.It looks as a compromise agreement has now been reached. 4.When George got absorbed in his world of music, he felt as he could “see” the beauty of the world around him. as if/though 引导的表语从句常置于连系动词look, seem, sound, be, become等之后。从句陈述的内容如果有明显根据,很可能发生,就用陈述语气;如果与事实不符,就用虚拟语气(若与现在事实不符,从句就用一般过去时(be动词用were);若与过去事实不符,从句用过去完成时)。 Dark clouds are gathering.

The reason is computers exist for humans, not humans for computers. 2. That is stone walls are used instead of fences around New England. 3. He did not see the film. That is he had to help his little sister with her homework. 4. My question is he likes the city center so much. 考点八 表语从句中的主谓一致、语序及时态问题 知●识●解●构 知识点1 表语从句的主谓一致需根据主句主语和表语从句的具体语境确定。 知识点2 表语从句的语序通常是陈述句语序,即主语在前,谓语动词在中间,其他成分在后。 知识点3 时态和语态:表语从句的时态和语态通常取决于主句的要求。 考●向●破●译 考向 考查表语从句中的时态 1.Dressed up, she looks as if she (be) ten years younger. 2.My suggestion is that we (catch) up with the other classes. 考点 九 主语从句的易错点 知●识●解●构 知识点1 that vs whether(高频考点) 看从句语义:语义完整(无“是否”含义)→ 用that;语义不完整(有“是否”选择)→ 用whether; 看主句主语:主句主语为reason时,表语从句只能用that,不可用because(易错点); 特殊注意:表语从句中that可省略,whether不可省略,且不可用if替代。 例句对比: His decision is that he will study abroad.(语义完整,用that,可省略) His decision is whether he will study abroad.(语义不完整,表“是否”,用whether) The reason is that he is ill.(正确:主句主语为reason,用that) The reason is because he is ill.(错误:不可用because,需改为that) 知识点2 what vs that(高频考点) that:无含义,不充当从句成分,只起连接作用,从句语义完整; what:有含义(“……的事情/东西”),在从句中充当主语、宾语、表语,从句语义不完整(缺成分)。 例句对比(易错警示): My wish is that he said at the meeting.(错误:从句缺宾语,that不能充当宾语) My wish is what he said at the meeting.(正确:what在从句中作宾语,指代“他说的话”) My wish is that he will come soon.(正确:从句“he will come soon”语义完整,that只起连接作用) 知识点3 whether vs if 表语从句中,只能用whether,不能用if(核心易错点,区别于主语从句“it作形式主语时可换if”),三种常见场景均需用whether: 1. 表语从句表“是否”,无论位置如何,均用whether; 2. 表语从句后接or not时,只能用whether; 3. 表语从句位于介词后(作介词宾语,本质还是表语从句),只能用whether。 例句对比: The question is whether he will come or not.(正确:表语从句+or not,用whether) The question is if he will come or not.(错误:表语从句不能用if) It depends on whether he will agree.(正确:表语从句位于介词on后,用whether) 知识点4 连接代词 vs 连接副词 解题依据:从句缺主语、宾语、表语、定语 → 用连接代词;从句缺时间、地点、原因、方式状语 → 用连接副词(与主语从句完全一致)。 例句对比: The problem is how we will get there.(从句“we will get there”缺方式状语 → 用how,连接副词) The problem is what we will take there.(从句“we will take there”缺宾语 → 用what,连接代词) The question is when we will get there.(从句缺时间状语 → 用when,连接副词) 考●向●破●译 考向 考查表语从句中的易错连接词 1. The problem is you can arrive at the airport in time or not. 2. The reason for their failure you know is they are lazy. 3.The reason why you got into a panic (恐慌) was you hadn’t been well prepared for what’s going to happen. 4.It is generally believed that communication skills are becoming it takes to be a good doctor. 5.Some people whose intention is to make big money appreciate being given any chance to multiply their income, believing this is their happiness lies. 6.The key to solving the traffic problem near our school is __________ the local government can build a pedestrian overpass before the new semester starts. 考点十 表语从句的思维建模 思维建模 ✅ 技巧1:判断是否为表语从句:看从句是否位于系动词之后,是否补充说明主语的身份、状态、内容等; ✅ 技巧2:分析表语从句成分:看从句中缺少什么成分(主语、宾语、表语、定语 → 连接代词;状语 → 连接副词;不缺成分 → 连接词that/whether); ✅ 技巧3:结合句意选择引导词:根据从句语义(是否表“是否”、是否表“无论……”、是否有选择范围),匹配对应的引导词,同时规避易错点(如reason后用that、不用if等)。 1. 主句主语为reason时,表语从句引导词只能用that,不可用because(高频易错); 2. 表语从句中,whether不可用if替代,无论是否接or not、无论是否位于介词后; 3. that引导表语从句时,大多数情况下可省略,但当表语从句较长、较复杂,或为了强调时,that不可省略; 4. what和that的区别:what充当从句成分,that不充当成分,从句缺成分用what,不缺成分用that; 5. 复合连接代词/副词(whoever/whatever等)表“无论……”,不可与no matter who/no matter what混淆(no matter...结构不能引导表语从句); 6. 连接代词whose后必须接名词,不能单独使用(如:whose is this 错误,应为whose book is this)。 真题溯源·考向感知 ——溯源真题逻辑,感知高考考向 单句填空 在空白处填入1个适当的单词或括号内单词的正确形式。 1.(2025北京卷)The truth, though, is could be guessed — there’s never anyone else here.
